The Red Exclamation Points (A Suspense/Thriller Mini-Novella)…

2017-07-27T00:01:02+00:00 June 18th, 2014|Uncategorized|

This evening was going like any other busy evening for a Coretek employee with a deadline fast approaching.  I was working with Citrix Support to figure out what the problem is with a Citrix XenMobile (an Enterprise Mobile Device Manager), when the dreaded warning texts started pouring in…

I received message after message about “servers down, 8:30 PM”…  The nice thing about it is I figured out who was by their phones to respond to the alerts.  After a quick couple of text messages, I acknowledged the alerts and began troubleshooting. 

I knew the issue was with our VMWare Vcenter Server, and my first reaction was, “…well I’m busy let’s just reboot this thing.”  So I rebooted the server and waited for it to idle down before launching VSphere, which now showed a bunch of orphaned VMs (“orphaned” is a bad word in Vmware, essentially meaning that a portion of the vm be it disk or configuration files can’t be located). 

So my mind starts racing to a network or storage issue.  I go to click on an orphaned VM and vSphere Crashed.  I now *Face Palm* myself (…sigh…) and go back to the vCenter server and attempt to start the service “VMware VirtualCenter Server.”  It starts, and as I open vSphere again, and it almost immediately crashes. 

So now I’m starting to get really nervous, and I’m thinking I’m going to need to do a restore; meanwhile, the support engineer from Citrix is on the line asking me to show her my Netscaler configuration and AppController configs.  I tell her, “I’ll show you what I have in a minute, ½ of my network just alerted me it is down.”  I believe it was one of those “lost in translation” moments because she waits and a minute later says, “well can I see the configs?”.  I give in show her the configs and run for another laptop from my desk to continue troubleshooting.  And as I log in and open Event Viewer on the vCenter server to see what is going on…  All I see are red exclamation points…


Red Exclamation Points!

So I have another *Face Palm* moment and think, “…Well, SQL Express 2008 R2 database size limit.  Ok, fun… now what…?”  Well Google here I come…

I found a few articles that talk about shrinking the database and truncating records…  It’s now 9:30 at night, I’m not feeling the “truncate my database” vibe tonight, so I continue reading on.  Eventually, I come across an article about cleaning up performance Data…  Well now, we don’t truly review performance data!  So why not clean that out, save some space and go home.  It’s now 9:50 ish…

So I have the plan of attack, and of course immediately roadblock #1 comes up: no SQL Management Studio on the box, and I don’t have another SQL box readily available.  So I back to google to find and download “SQL Server Express 2008 R2 with tools”…  except there are not stinkin’ tools in this package!  Argh!  Howver, hopping over to my MSDN subscription, I download “SQL Server 2008 R2 Express with Tools X86” and lucky me, the tools are actually there.  It’s now 10:30 ish…

Now roadblock #2: I took over this network and environment and I don’t know the account and password to use.  So I try my domain admin account…  Nope, public access only.  Well, I’m not a DBA — and I don’t claim to be a SQL Expert — so Google, here I come again… 

One of the top results is a Microsoft article on how to get access.  So in following this article, I stopped the Vmware services and added the –m parameter in the service start-up.  I proceeded to log in with my domain account (NOTE: RUN MANAGEMENT STUDIO IN PRIVLIDGED MODE, a.k.a. “Run As Administrator”) and my new shiny tools.  Once logged in, I created my account and provided myself with sysadmin rights to the instance.

I then backed up the databases to the D: drive (separate the OS and Database), and then ran the Script I got from the above VMware Article.  It worked like a charm, and in under a minute I cleared ½ of my database and was up and running.  Now, back to the Citrix support call…  It’s now 10:45… 

The End….?



Converting a VMware Linux Guest to Hyper-V…

2017-07-27T00:01:02+00:00 May 1st, 2014|Uncategorized|

If there were enough room, the full title for this article would actually be something more like, “Converting a Suse SLES or Opensuse Linux machine from either VMware Workstation or ESXi or to Hyper-V, even when you don’t have the VMware environment anymore…

To give you a little background, Microsoft recently released the MVMC v2 (, packed with some critical new features, including better handling of Linux VM guests.  And it just so happens that I have a small handful of dev/test Linux machines lying around from a VMware lab environment that I tore down a while ago that I’d love to have in my Hyper-V lab.  The problem is that I just don’t have the VMware workstation or space on my ESXi servers to bring the VMs back up and follow the standard documented procedure.

If you haven’t figured it out already, the basic problem here is that the Linux VMs (that came from the VMware environment) don’t have the Hyper-V drivers configured because they weren’t needed at installation (again, on VMware), but the Installation ISOs *do* have the drivers at the ready when booting the “rescue system”.

And while the very nice documentation provided with the converter kit (Microsoft_Virtual_Machine_Converter_Admin_Guide_2_0.docx) gets you close to knowing what you need to do, it doesn’t quite provide you with step-by step instructions, especially with the guests already downed or in an archive.


Without further ado, here’s how to convert and fix those Linux VMs.  Of course, there are a few particulars here; for instance, this procedure was tested with Opensuse versions 12.2 and 12.3, and SLES 11 sp3, but should be the same for other similar versions.  And it should go without saying that by following these instructions, you proceed at your own risk. 

Step 1: Install MVMC2

First, the installation.  Go to the MVMC2 download site, get the software, and install.  I recommend doing this on a Windows 8+ or Server 2012R2 machine, for a few small niceties (like defaulting to vhdx format, etc.).

Step2: Convert the Disk

Open Powershell *as Administrator* (right-click, run as Administrator), and load the module:

Import-Module "C:Program FilesMicrosoft Virtual Machine ConverterMvmcCmdlet.psd1"

We need to create a temporary folder for our converted disk — in my case on a separate drive from where my source VMs reside, to speed things up a tad:

md c:MvmcResults
cd c:MvmcResults

And then we can convert out source disk:

ConvertTo-MvmcVirtualHardDisk -SourceLiteralPath "E:Virtual MachinesOpensuse12.3Opensuse12.3.vmdk"

Next, move the newly converted disk to wherever you keep your virtual hard disks (I assume you have a designated location).

Then, create a Generation 1 Virtual Machine in Hyper-V (try to use the same name, memory settings, and so on as before), but choose to “Use an existing virtual hard disk” and set it to the newly converted hard disk.  But before you start it, attach the correct installation ISO (I use the tiny “network install” ISO).  Remember, it’s mandatory that you use the correct processor type ISO (32 vs. 64), and you should use the correct distro version.

Step 3: Boot and Mount the Alternate Root

Start the VM (booting from ISO), and choose “Rescue System” as the boot choice.  Tip: while the splash screen is up, hit the escape key and notice the Hyper-V drivers it chose; in my case it was only hv_netvsc and hv_storvsc, but you may have others.

Once at the “Rescue” prompt, enter “root” as the login.

Now, mount the proper disk partition for your root filesystem; this may take some guessing if you don’t remember which is which.  For instance, on some of my lab machines, I used /dev/sda2 as the full root filesystem.  On others, I created a separate partition for /boot, so the root file system was on /dev/sda3.  If you don’t know, you might have to mount a few of them and look and see what’s in them.  And of course, if you have a separate /boot, you’ll have to mount that too.  But for the examples that follow, we’ll assume the full root file system is all on /dev/sda2.

So mount the root filesystem under the alternate mount point, like this example:

# mount the root
mount /dev/sda2 /mnt
# you may have to mount /boot too, depending on your setup
# mount /dev/sda1 /mnt/boot
# you must re-mount the live dev and proc
mount -–rbind /dev /mnt/dev
mount -–rbind /proc /mnt/proc
# set the chroot environment
chroot /mnt

…and then we’re ready to actually do some fixing.

Step 4: Fix the Modules

(These next instructions are re-interpreted from the MVMC2 guide, courtesy Microsoft):

Use vi to edit /etc/sysconfig/kernel to include the Hyper-V modules.  Sorry, there’s not enough room here to teach you how to use vi…  😉  Add the “hv_” modules to the end INITRD_MODULES line, which *may* look something like this:

INITRD_MODULES="mptspi ata_piix ata_generic vmxnet3 vmw_pvscsi vmxnet”

…or perhaps like this (this example does not have VMtools drivers):

INITRD_MODULES="mptspi ata_piix ata_generic”

…and with your change, you’re making it look more like this (again, we’re only adding the hv_ modules to the end):

INITRD_MODULES="mptspi ata_piix ata_generic vmxnet3 vmw_pvscsi vmxnet hv_vmbus hv_netvsc hv_storvsc”

And finally, recreate the initrd with something similar to the following command (this example is taken from one of my older ones). The kernel and initrd specified in the command must match your current kernel the machine boots with.

mkinitrd -k /boot/vmlinux-3.7.10-1.11-desktop.gz -i /boot/initrd-3.7.10-1.11-desktop

…and you’re done!  Type “exit” to end the chroot environment, and “init 0” to shut down.  Go to the settings of the VM, and detach the ISO, and boot it up.

Phew!  You did it.  Enjoy your Linuxy goodness…


DFS Replication Validation Script…

2017-07-27T00:01:04+00:00 December 12th, 2012|Uncategorized|

The other day, while at the enterprise-level customer with whom I’m currently working, I ran into a situation where I needed to validate that certain parts of a DFS hierarchy were properly being replicated across the customer’s AD domain controllers.  As the administrators applied normal, routine DFS changes, the changes sometimes didn’t replicate properly across the enterprise — causing some segments of the DFS structure to not be visible or available. 

Apparently, the DFS problem was a result of using VMware guests as AD DCs.  I understand (from the customer) that a Microsoft hotfix is in the last stages of testing (at the time of this writing) and will be available for release “soon.”   It seemed that even though the DCs in question did not synchronize time with the ESX host upon which they reside, there is a default behavior in VMware Tools that assigns the host time value to the guest — at least up until the “do not sync” routine is processed during startup; after which the guest is then allowed to find its own time.  During this brief time window, the DFS Namespace service sometimes completes assembling its DFS target list and can find itself behind in time, relative to links it has been given by PDCE; which makes no sense to it, and it removes them from its listing.  And as a result, people can’t find their mapped drives or browse some of the DFS Tree.  (Note: I cannot take credit for this timing behavior investigation and results; and while I’d love to credit the folks who are due, I’m not permitted to.)  The customer remedied the situation with a temporary fix, but the real fix is the up-coming aforementioned patch.

Anyway, while the symptoms were being analyzed, I was working on other things and needed to work around the issue as much as possible while the solution was being chased.  So, I whipped up a simple little DOS script to go out and validate the top-levels of the DFS hierarchy across all domain controllers that carry them, in order to find out what would or wouldn’t be properly resolved.

For what it’s worth, I thought I’d pass the script along to you.  Here it is:


@set AdDomain=MyAdDomain.local
@set DirQuantity=17
@set DestPath=h:DcList.txt
@REM This requires elevated credentials, otherwise will fail...
@ipconfig /flushdns
@REM First we build the input file...
@nslookup %AdDomain% |findstr 
[0-9].*.[0-9].*|findstr /V /C:"Address: " > %DestPath% @ECHO As of 20121212, there should be %DirQuantity% DFS dirs on each server (actual, plus the "." and ".." items). @REM Now loop through the input file and check the DFS at the destination... @For /F "tokens=*" %%Q in (%DestPath%) Do @( @set MYDC=%%Q @set MYDC=!MYDC:Addresses: =! for /f "tokens=* delims=" %%A in ('dir /A:D \!MYDC!Corp ^|findstr /C:"Dir(s)"') do @set MYDIR=%%A for /f "tokens=* delims= " %%G in ("!MYDIR!") do @set MYDIR=%%G @REM Options A: Use this line if you wish to see all DFS sources: @ECHO For: !MYDC! !MYDIR:~0,9! @REM Option B: Use this line if you wish to see only those in violation @REM (note: there's a space and tab separator for spacing alignment): @REM @ECHO For: !MYDC! !MYDIR:~0,9! |findstr /V /C:"%DirQuantity% Dir(s)" )

What it does:

The script builds a domain controller list in a static, external file, then iterates through the list, attempting to quantify the available DFS path branches against a numeric count that you supply in another variable.  I provided two different “ends” to the script (one of them commented out), in order to give you a couple different ways to present the results.  Make sure to “set” the variables in the first few lines, to your locally-relevant information; especially the number of *expected* DFS hierarchies.

Of course, I wanted to write it to do more, but I pretty much ran up against the limits of what I *should* do in a DOS script.  I’ll make another version in PowerShell some day that iterates down the hierarchy and validates the entire structure, instead of just the top level… 

…Unless you beat me to it…  😉

There you go; enjoy!




Windows 8, Week 1…

2017-07-27T00:01:05+00:00 October 31st, 2012|Uncategorized|

Well, it’s been almost a week since I upgraded my laptop to Windows 8, and it’s actually been a very smooth ride so far.  However, I’ve had to deal with just a few twists in getting used to some of the new locations and limitations of the things I’ve always been used to in Windows XP and Windows 7.  So, I thought I’d toss together a few tips from my first week of use, and I hope you’ll toss a few back at me!

Shutdown and Reboot buttons

Shutting down a Windows 8 computer is not as immediately obvious as it used to be.  There are a couple “new” ways of shutting down your Windows 8 machine, for instance:

  • Mouse to bottom-right –> Settings –> Power –> Shut down
  • (Win Key) + I –> Power –> Shut down
  • (Win Key) + C –> Settings –> Power –> Shut down
  • (Win Key) –> Right click on username (at top right) –> Lock/Sign out –> Right-click on lock screen –> click on power icon at bottom right

But I needed an easier way.  Fortunately, if you invest a few minutes now, you’ll have easier Shutdowns and Reboots for years to come.  Here’s how to do it:

  • In Windows Explorer, go to this folder:
  • C:Users(username)AppDataRoamingMicrosoftWindowsStart MenuPrograms
  • Right-click and choose New –> Shortcut
  • For the “location”, type: shutdown /s /t 00
  • Click Next, and for the “name”, type: Shutdown Now
  • Click Finish, and press the (Win Key).
  • Right-click the new “Shutdown Now”  app tile, and choose Pin to taskbar
  • Resume sanity
  • (Note: You can create others, like “Restart Now” with shutdown /r /t 00 and “Delayed Restart” with shutdown /r /t 10 etc.)

…by the way, that tip for adding shortcuts on the taskbar works great for other things too; effectively bringing back your shortcuts menu that you were so used to

Wireless Driver Back-Rev

Of course, I couldn’t resist mentioning our awesome post about back-revving your Windows 8 “n” wireless driver to a Windows 7 driver version — since I had to do that this week too, in order to be able to stay productive.  So far this week, we’ve been noticing that this seems to predominantly affect Broadcom-based drivers, and Intel-based drivers seem to work fine in some cases.  It’s only the first week, so we’ll be watching that…

VMware and Hyper-V

I was excited to find out Hyper-V was included in Windows 8.  Unfortunately, I cannot use on it yet on my Windows 8 laptop.  As part of my work/experimentation in my current role, I have to keep virtual machines like NetWare, CentOS, Opensuse, and other non-mainstream OS’s around for scripting, and testing automation and integrations, and such.  And while I’m thrilled that Hyper-V supports a few recent versions of CentOS and the latest version of Opensuse (12.1 at this writing), it still does not support NetWare and a guest OS.  As a result, I’ve had to choose VMware workstation of my hypervisor of choice on my laptop for now (since VMware and Hyper-V cannot co-exist on the same base hardware), and I’ll run Hyper-V in the dedicated lab instead.

Remote Desktop Connection Manager

The Remote Desktops snap-in for the MSC is gone!  It’s not available in Windows 8.  If you know what that means, then you’re probably as upset as I was.  Fortunately, I discovered that the old Remote Desktop Connection Manager still works on Windows 8!  Phew!  Honestly, it’s a better tool anyway. 

So Far, So Good…

…So that’s where I’m at so far.  The good news is that just about everything I’ve brought over to Windows 8 so far from my Windows 7 world has worked perfectly.  And I “get it” now; what I mean by that is that I understand and appreciate the dual layer effect of the “tablet-like” OS on top of the “traditional-style” OS.  Now that I’m able to dance easily between them, I quite like it and am eager for a Windows 8 based tablet, actually.  Hint, hint…

Now, share some of your tips, please!



How to check the VMware Tools version across your Windows Server 2008 R2 farm…

2012-06-20T22:40:00+00:00 June 20th, 2012|Uncategorized|

I was on a conference call today where someone asked if the server administration team could quickly get a “read” on the VMware Tools version across the server farm.  An ESXi upgrade was being deployed and the team wanted a quick way to see what VMs needed to catch up with the deployment.

Fortunately, I had a bunch of PowerShell snippets lying about that would fit the bill nicely.  Of course, there are a few different ways to accomplish this, depending upon which resources that you are permitted to access; but using PowerShell in a loop with a list of your server names is a quick and easy way to get it done.

So first, a little set up…  Imagine that we are inside a PowerShell script, in a foreach loop (or a function called by that loop) that is calling each computer (our Windows 2008 R2 servers) in a list.  At the time you hit this snippet of code, the current server name in the loop is in the variable $ComputerName, and the output file for the report is $outfile


    write "" | Out-File $outfile -append
    $vmtoolstatus = Get-WmiObject -class Win32_Product -computername $ComputerName | Where-Object {$_.Name -match "VMWare Tools"} |select Name,version
    if ("X$vmtoolstatus" -eq "X")
      write "VMware Tools **NOT** found." | Out-File $outfile -append
      write "WMware tools presence/version info:" | Out-File $outfile -append
      $vmtoolstatus | Out-File $outfile -append


All we’re really doing here is to query the product list for the tools, and if present report the version. And the result look something like this for each item in the loop:

WMware tools presence/version info:
Name                                                        version                                                  
----                                                        -------                                                    
VMware Tools                                      

Simple, but effective and functional. 

I hope it helps!



A FlexPod Brief…

2012-05-02T22:31:06+00:00 May 2nd, 2012|Uncategorized|

With the rise of virtualization over the last several years, there’s one large segment of Information Technology that has been struggling to keep up with the demand – your organization’s data center. 

Not So Long Ago…

IT infrastructure used to be built and deployed using distributed technology and components on an application-by-application basis.  That philosophy worked well because most IT teams were organized in silos that segmented applications, servers, local area networks, and storage groups.

As more applications were required across multiple departments, that infrastructure development strategy became far less efficient.  Server sprawl become a serious concern as more and more servers were required to deliver software solutions.  It took longer to build and deploy environments.  It also turned the data center into one of the least “green” places in an organization due to the immense power requirements needed to power the core infrastructure.

Virtualization changed much of that in the last few years by re-imagining a consolidated data center that significantly reduced the number of servers required to deliver Tier 1 applications for the enterprise.  The result is a more flexible, easier to manage environment that has reduced power demands.  Building this type of infrastructure can be very simple when you use a building-block solution like FlexPod.

A New Approach…

Introduced a little over two years ago, FlexPod offers a set of validated infrastructure designs that allow you to build a robust data center with a very dense infrastructure footprint confined in a small amount of space.  The FlexPod system is built around a baseline configuration that includes servers and switches from Cisco, high-performance storage from NetApp, and virtualization components from Citrix, VMware, or Microsoft, depending on your Hypervisor preference.

All FlexPod solutions begin with a standard – but flexible – blueprint which can be modified to suit your organization’s unique needs.  This base configuration can be scaled quickly to meet any number of infrastructure needs, but FlexPod truly shines in the virtualization space.

Because all three components of FlexPod are tightly integrated, supporting FlexPod is considerably simpler than with a traditional server model.  All patches, upgrades, and enhancements are pre-tested to ensure they work seamlessly during implementation.  This reduces risk during critical updates and time required when performing basic maintenance tasks.

What Cisco Brings…

Cisco has done a phenomenal job of leveraging their popular Unified Computing System (UCS) platform to serve as the backbone of the FlexPod environment.  Cisco’s new B- and C- Class series servers significantly increase performance and capacity for large data-heavy virtualized environments by serving up a whopping 384GB (and even more in some models) of memory per blade server.  Cisco’s UCS M81KR Virtual Interface Card improves network throughput performance by 38% over similar software-based switches, and reduces cost by performing as both a network interface care and a host bus adapter.  The result is the elimination of key bottlenecks that directly impacted performance on virtual servers.

Cisco also includes the Unified Computing System Manager (UCS-M) as part of the FlexPod environment.  This provides for management of all software and hardware in the stack.  UCS-M also offers flexible role and policy-based management of the entire environment using services profiles.  Resources can be placed in pools, and service profiles can be used to help speed up time to market for key deployments.

The NetApp Piece…

NetApp provides a huge boost to the FlexPod environment by offering a wide array of software aimed at maximizing storage.  NetApp’s de-duplication process drives the cost of storage down dramatically by intelligently writing only truly unique data to its drives.  Using its FlexClone technology, users can quickly provision new environment for use in development, testing, or disaster recovery.  Innovations like NetApp’s FlexCache technology allow high-demand data to be segregated from data in its main repositories to ensure for quick access and maximum performance.

Greater Than The Sum…

Add this all up and it’s clear that FlexPod is a real game changer.  Whether your organization is looking to reduce its footprint in the data center, drive better performance it its virtualized environments, or simplify the management of the data center, FlexPod’s certainly a technology worth keeping an eye on.

How the Cloud Is Transforming IT

2017-07-27T00:01:08+00:00 March 13th, 2011|Uncategorized|

In a business world where first movers gain the advantage and IT is central to every decision, IT responsiveness and agility provide a competitive edge. Yet many IT organizations aren’t quick enough on the uptake because their infrastructures are exorbitant to manage and too complex to easily adapt.

Cloud computing provides a vastly more efficient, flexible, and cost-effective way for IT to meet escalating business needs: IT as a service. VMware offers you an evolutionary and practical path to this new model, with solutions that harness the power of the cloud while ensuring security and preserving the value of your existing technology investments.

VMware’s Approach: Enabling the Journey to Your Cloud

Virtualization is the essential catalyst for cloud computing. As the virtualization leader, VMware builds on this solid foundation with platforms and solutions to pow

er your cloud infrastructure, build and run robust cloud applications, and supply end-user computing as a cloud-based service.

Our approach is comprehensive, but unlike other cloud offerings, it’s not one-cloud-fits-all. To deliver competitive advantage, cloud computing must be flexibly tailore


d and aligned to your individual needs. For your enterprise, that could mean a cloud that’s internal and private, one that leverages external services, or a hybrid cloud that combines both.

Whichever cloud option suits you best, only VMware offers a complete solution stack for building and managing it, plus a broad partner ecosystem to ensure that everything in it works seamlessly and securely. The result is not just any cloud, but your cloud—where accelerated IT delivers accelerated results for your business.

VMware’s tailored approach delivers flexibility and security while protecting your existing investments, by enabling:

  • Efficiency Through Utilization and Automation
    Resource pooling and a self-managed, dynamically optimized environment dramatically increase IT performance—leveraging existing resources to avoid unnecessary infrastructure investment and technology lock-in. The result is lower total cost of ownership (TCO).
  • Agility with Control
    Cloud computing aims to empower end-users while ensuring security and preserving IT oversight and authority. The VMware solution interweaves all three, greatly simplifying IT services provisioning and deployment while maintaining IT control, protective safeguards, and regulatory compliance. The IT organization can thus respond more quickly and securely to evolving business needs.
  • Freedom of Choice
    IT retains the ability to support traditional systems and gains the flexibility to deploy them internally or externally, without being restricted to any single technology or vendor. Developers can build applications that are portable among hybrid, private, and public clouds within a common management and security framework.

 Our Solutions. Your Cloud. Key Advantages.

VMware solutions are engineered and integrated to equip your cloud with a unique combination of benefits:


VMware solutions deliver always-on, virtualization-aware security that adapts to the dynamism of cloud-based deployments while simplifying the protection of endpoints, applic

ations, and the network edge.

Automation and Management

Once IT resources are virtually pooled, business rules, policies, and defined service levels are mapped to them, creating a highly efficient, self-managing i


nfrastructure where IT is available as a service.

Interoperability and Openness

With a shared management and security model based on open standards, VMware solutions free you from vendor lock-in, ensuring application portability between internal datacenters and external service provider clouds hosted by VMware vCloud partners. Additionally, the </LINK 34657>VMware cloud application platform lets developers build robust modern applications that are portable, dynamic, and optimized for elastically scalable deployment on popular public clouds such as VMforce and Google App Engine.

Self-Service for the Cloud

Our approach delivers a new level of IT efficiency by standardizing and automating IT services provisioning and management. Rather than having to wait for manual provisioning, line-of-business units can deploy standardized, preconfigured IT services from a Web-based catalog available via a self-service portal. Business units receive tailored services right when they need them, IT administrators are relieved of the bulk of their maintenance burden, and IT preserves control over policies, compliance, and internal chargeback.

Pooling and Dynamic Resource Allocation

Your IT resources are pooled and abstracted into logical building-blocks of storage, network, and server units—effectively creating virtual datacenters. These resource containers are then dynamically allocated to your various applications, governed by defined business rules and user demand.


Join the Evolution to Your Cloud

Cloud computing holds the very real promise of agile, efficient IT service delivery with dramatically lower complexity, significantly reduced costs, and much greater business responsiveness. The key to realizing these advantages is tailoring the cloud model to work for your business and your approach to IT.

As the acknowledged leader in virtualization and cloud infrastructure, VMware is uniquely positioned to help you transition to your cloud—the private, public, or hybrid c


loud environment that’s best fits your business needs and goals. Thousands of enterprises have already achieved exceptional results with VMware solutions. And because our approach is open, flexible, a


nd geared to addressing individual needs, they’ve done so without a heavy customization burden.


VMware offers a 3-layered solution stack to supports your evolution to the cloud:

  • Cloud Infrastructure and Management. The foundation for your cloud, based on virtualization and the ability to unify private and public cloud resources with consistent security, compliance, management, and quality of service.
  • Cloud Application Platform. Enabling developers to rapidly build and run modern cloud applications while deploying on premises or off for maximum flexibility.
  • End-User Computing. Creating a modern, user-centric approach to personal computing, delivering secure access to applications and data from any device, anytime and anywhere.

ApplicationHA and VirtualStore to protect systems from downtime and optimize storage in VMware environments


Symantec Corp. (Nasdaq: SYMC) today announced that it will offer Symantec ApplicationHA and Symantec VirtualStore, two solutions that will provide customers the ability to confidently virtualize their business critical applications and minimize storage costs on the VMware platform. ApplicationHA and VirtualStore are the result of extensive collaboration between Symantec and VMware, as the companies work closely to help customers accelerate the adoption of virtualization to mainstream applications.

Symantec ApplicationHA, based on industry-leading Veritas Cluster Server technology, will provide high availability for business critical applications through application level visibility and control in VMware environments. Symantec VirtualStore, based on Veritas Storage Foundation technology, is a software-based storage management solution for VMware virtual machines that will provide rapid provisioning of servers and virtual desktops, efficient cloning and accelerated boot up of virtual machines. Both ApplicationHA and VirtualStore are seamlessly integrated with VMware management tools such as VMware vCenter Server, enabling customers to deploy these tools without impact to their operational model.

Customers have been aggressively virtualizing non-critical applications, and now that they are starting to move business critical applications like SAP and MS SQL Server databases to virtual platforms, they require high availability of the applications inside VMware virtual machines. Symantec ApplicationHA, for the first time, will ensure application high availability by providing visibility, control and integration with VMware vCenter Server and VMware High Availability (HA).

Symantec ApplicationHA:

  • Monitors applications’ health status and detects failures in the virtual machine
  • Restarts failed applications
  • Coordinates with VMware HA to restart the virtual machine, if needed


Administrators can fully manage all operations of Symantec ApplicationHA through VMware vCenter Server, avoiding the need for additional tools and associated training. Deep discovery and auto-configuration allows administrators to easily install, configure and administer Symantec ApplicationHA with a few clicks.

Built on the industry-leading Veritas Cluster Server technology, ApplicationHA supports a wide range of applications including MS SQL Server, Exchange, IIS, Oracle and SAP. It provides consistent functionality and usability across both Windows and Linux operating systems and is fully compatible with VMware vMotion and VMware Distributed Resource Scheduler (DRS).

Symantec VirtualStore: Address Storage Challenges in Virtual Infrastructures

As organizations scale their virtual environments, they find themselves challenged by the ever increasing storage requirements and performance bottlenecks that are associated with retaining hundreds or even thousands of virtual machine images on traditional hardware filers. VirtualStore will enable administrators to fully benefit from their virtualization investments with a software-based NAS solution that scales servers and storage independently, efficiently provisions virtual machines, and delivers advanced storage optimization capabilities for VMware environments.

Like ApplicationHA, VirtualStore fully integrates with VMware vCenter Server. Based on Symantec’s industry leading Veritas Storage Foundation technology, VirtualStore can:

  • Help customers reduce storage costs associated with virtual machine sprawl and improve the performance of virtual infrastructures
  • Enable administrators to dramatically reduce the cost per virtual machine by repurposing existing storage investments or using inexpensive or commodity storage
  • Help IT organizations reduce their storage footprint by storing only the differences between the parent virtual machine image and each clone
  • Significantly drive down total cost of ownership by taking advantage of the benefits of thin provisioning


Virtual Desktop Infrastructure (VDI) environments can also be managed more efficiently. VirtualStore’s ‘FileSnap’ feature lets administrators easily and rapidly clone and provision thousands of virtual machines in minutes through its VMware vCenter Server integration. Through innovative page caching, VirtualStore also eliminates the performance bottlenecks created when multiple users boot up their virtual machines (‘Bootstorm’).
