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.

Symantec Endpoint Protection 12 Delivers Unrivaled Security with Fastest Performance

2017-07-27T00:01:08+00:00 March 2nd, 2011|Uncategorized|

Symantec announces new versions of Symantec Endpoint Protection and Symantec Endpoint Protection Small Business Edition (currently in beta), providing businesses of all sizes with advanced protection while improving system performance. Complete with advanced features to secure virtual infrastructures and powered by Insight, Symantec’s award-winning community and cloud-based reputation technology, Symantec Endpoint Protection 12 is designed to detect and block sophisticated new threats earlier and more accurately than any other security product.

Security threats have become more sophisticated and more widespread, creating a challenge for traditional signature-based security solutions. Last year, attackers unleashed more than 286 million distinct malicious programs, an average of more than nine new threats every second of every day. This explosion in malware scope and complexity is due in large part to the proliferation of easy-to-use attack toolkits—such as Zeus—which lower the barrier of entry in cybercrime. These toolkits enable hackers to continuously generate new mutated malware variants, each targeting a different victim, making traditional discovery and fingerprinting of these threats nearly impossible. According to Symantec’s Attack Toolkits and Malicious Websites Report, at least 61 percent of threat activity can be attributed to attack toolkits. As these toolkits grow in popularity, the trend towards millions of narrowly distributed, high impact threats will continue. Symantec Endpoint Protection 12 leverages Insight to provide unmatched protection against this new threat landscape.

Key Benefits

  • Unrivaled Security: Symantec Endpoint Protection 12 blocks new and unknown threats missed by traditional signature, heuristic, behavioral and HIPS-based security solutions. All of the product’s security engines are now reputation-enabled, leveraging Insight’s online reputation database to identify and block malware attacks. Symantec’s Insight has analyzed the anonymous software adoption patterns from more than 175 million customer computers to automatically derive highly accurate security ratings for more than 2.5 billion unique software files—Insight has ratings for virtually every software file, good or bad in existence. In addition, SONAR 3, the world’s first hybrid behavioral-reputation engine, blocks zero-day and highly targeted threats based on their joint behavior-reputation profile. As part of a commissioned test, the leading security testing organization, AV-Test.org, recently compared a number of major endpoint security products on their effectiveness in blocking new threats as well as cleaning up pre-existing infections. Symantec Endpoint Protection 12 (beta) received the top score against all tested competitors in both categories.
  • Fastest Performance: Symantec Endpoint Protection 12 leverages cloud-based community intelligence to reduce the overhead of virus scanning by as much as 70 percent by using Symantec Insight to automatically identify and whitelist trusted high-reputation files, resulting in fewer, faster and smarter scans. The new, Insight-driven compatible scan engine is also designed to do most of its work while computers are idle. In the latest roundup of PassMark Software’s performance test of enterprise and small business security solutions, Symantec Endpoint Protection 12 reported the fastest scan speed and was found to be twice as fast as the average security solution. Symantec Endpoint Protection 12 also used the least memory,57 percent less memory usage than the average security solution.
  • Built for Virtual Environments: Symantec Endpoint Protection 12 offers comprehensive defense against all types of attacks and is optimized for performance on virtual systems. Symantec Endpoint Protection 12 can whitelist baseline images, maintain a local Insight cache, randomize scans and updates, and automatically identify and manage virtual clients. This is above and beyond the performance improvements gained with Insight. Together these innovations dramatically reduce the load on virtual hosts, alleviating ‘AV Storms’/concurrent scans from bogging down system resources and allowing for faster, more responsive systems, which can in turn support greater density of virtual instances. Symantec is working closely with VMware to take full advantage of virtualization awareness and introspection capabilities based on VMware vShield™ technology and Symantec Endpoint Protection 12 is the first step along the optimization path for virtual environments.
  • Small Business Edition: Leveraging Insight and Sonar 3, Symantec Endpoint Protection Small Business Edition offers enterprise-class threat detection technologies and performance improvements with simple to use features such as an installation wizard, pre-configured policy settings and automated notifications and reports for small business customers. Symantec Endpoint Protection Small Business Edition meets small business needs with the fastest, most effective anti-malware capabilities in the industry. Small businesses will have peace of mind that their data is safe from cybercriminals, so that they can stay focused on growing their businesses.

Beta Registration and Availability

Presently, Symantec Endpoint Protection 12 is in an invitation-only beta and is expected to be available for public beta in April 2011. The new versions of Symantec Endpoint Protection 12 are scheduled to be generally available later this year and can be purchased through Symantec’s worldwide network of value-added authorized resellers, distributors and systems integrators or directly.

Virtual Servers, Real Growth

2017-07-27T00:01:09+00:00 July 12th, 2010|Uncategorized|

 

If you follow tech industry trends, you’ve probably heard of cloud computing, an increasingly popular approach of delivering technology resources over the Internet rather than from on-site computer systems.

Chances are, you’re less familiar with virtualization — the obscure software that makes it all possible.

The concept is simple: rather than having computers run a single business application — and sit idle most of the time — virtualization software divides a system into several “virtual” machines, all running software in parallel.

The technology not only squeezes more work out of each computer, but makes large systems much more flexible, letting data-center techies easily deploy computing horsepower where it’s needed at a moment’s notice.

The approach cuts costs, reducing the amount of hardware, space and energy needed to power up large data centers. Maintaining these flexible systems is easier, too, because managing software and hardware centrally requires less tech support.

The benefits of virtualization have made cloud computing an economical alternative to traditional data centers.

“Without virtualization, there is no cloud,” said Charles King, principal analyst of Pund-IT.

That’s transforming the technology industry and boosting the fortunes of virtualization pioneers such as VMware (NYSE:VMW – News), Citrix Systems (NMS:CTXS), two of the best-performing stocks in IBD’s specialty enterprise software group. As of Friday, the group ranked No. 24 among IBD’s 197 Industry Groups, up from No. 121 three months ago.

1. Business

Specialty enterprise software represents a small but fast-growing segment of the overall software enterprise market, which according to market research firm Gartner is set to hit $229 billion this year.

As with most software, the segment is a high-margin business. With high upfront development costs but negligible manufacturing and distribution expenses, specialty software companies strive for mass-market appeal. Once developers recoup their initial development costs, additional sales represent pure profit.

Software developers also make money helping customers install and run their software, another high-margin business.

But competition is fierce. Unlike capital-intensive businesses, software companies require no factory, heavy equipment, storefront or inventory to launch. Low barriers to entry mean a constant stream of new competitors looking to out-innovate incumbents.

In addition to the virtualization firms, notable names in the group include CA Technologies (NMS:CA) and Compuware (NMS:CPWR).

All offer infrastructure software to manage data centers.

“Big-iron” mainframe computers began using virtualization in the 1970s, around the time when CA and Compuware were founded.

In the late 1990s, VMware brought the technology to low-cost systems running ordinary Intel (NMS:INTC) chips. VMware has since emerged as the dominant player in virtualization.

Citrix has added a twist to the concept, virtualizing desktop computers. Rather than installing workers’ operating system and applications on hundreds of PCs spread across the globe, companies can use the technology to run PCs from a bank of central servers. Workers, who access their virtual PCs over the Internet, don’t know the difference.

Microsoft (NMS:MSFT) has jumped in with its own virtualization product, HyperV, which it bundles free into Windows Server software packages. Oracle (NMS:ORCL) and Red Hat (NYSE:RHT – News) have launched virtualization products as well.

Meanwhile, CA and Compuware are racing to move beyond their mainframe roots to support virtualization and cloud-computing-enabled data centers. In February, CA said it would buy 3Tera to build services and deploy applications aimed at the cloud-computing market.

And Compuware bought privately held Gomez, Inc. last fall to manage cloud application performance.

Name Of The Game: Innovate. With a fast-moving market and steady influx of new competitors, keeping customers happy with good service and money-saving breakthroughs is vital.

2. Market

Nearly everyone who runs a corporate computer system is a potential buyer of virtualization software. Companies ramping up their information-technology purchases use the software to manage their sprawling infrastructure; others with limited budgets use it to squeeze more out of their existing systems.

Sales of server-virtualization software are set to grow 14% this year to $1.28 billion, according to a report by Lazard Capital Markets. Sales of software to manage virtual environments will grow 44% in 2010 to $1.88 billion.

Desktop virtualization revenue will rise 184% this year to $847.8 million. Citrix has the edge in this budding market with its XenDesktop product.

VMware is dominant among large enterprises, controlling about 85% of the server virtualization market. Microsoft is favored by small and midsize companies.

Virtualization is seen as “a strategic asset” for enabling cloud computing, and continues to gain momentum, says Lazard analyst Joel Fishbein.

VMware has the early-mover advantage in this market with its vSphere platform and has stayed ahead by adding new features such as data security and disaster recovery, analysts say.

But Citrix is partnering closely with Microsoft to take on VMware in virtualization.

3. Climate

Competition is heating up as companies scramble to adopt virtualization. Before 2009, just 30% of companies used virtualization, says analyst Fishbein. This year, that will double to 60%. Most of the gain is coming from small and midsize customers.

In addition, virtual servers are soon expected to more than double as a percentage of the overall server workload, from 18% today to 48% by 2012.

VMware says it can stay a step ahead of the pack by building new features into its products, says Dan Chu, VMware’s vice president of cloud infrastructure and services.

“We have a large technology lead with what we enable for our customers,” Chu said. “We are several years ahead of what the others are doing.”

Citrix CEO Mark Templeton says his firm’s broadening strategy — offering a variety of products with multiple licensing options and distribution channels — will grow sales.

“What’s going on is a massive shift in how computing gets delivered,” Templeton said. “In an environment that’s changing so dramatically, the highest-risk thing you can do is not act.”

4. Technology

The first virtualization boom stemmed from a shift over the last decade away from big expensive mainframes and minicomputers to massive banks of cheap Intel-powered machines. Virtualization gave these low-cost systems some of the high-end features of their pricier counterparts.

Virtualization software makers are betting on a second wave of growth fueled by the industrywide shift to cloud computing.

Technology managers use virtualization to run cloud computing in their own data centers. And large tech vendors such as Microsoft use the technology for cloud-computing services they sell to customers.

Dividing computers into isolated virtual machines gives cloud service providers the benefits of shared computing resources without the security downsides.

VMware has the early lead in virtualization. But the technology is quickly becoming a commodity as Microsoft and others bundle it into their broader platforms.

“VMware is known as a virtualization company, and Microsoft is a platform company,” said David Greschler, who heads up Microsoft’s virtualization efforts. “Their strategy is to sell virtualization, but our strategy is to make virtualization available as part of a larger platform at no extra cost.”

At the same time, a shift toward a world of cloud-computing services hosted by the likes of Microsoft, Amazon.com (NMS:AMZN) and Google (NMS:GOOG) could lead to fewer companies purchasing virtualization software themselves.

Server Virtualization- Under the Hood

2017-07-27T00:01:11+00:00 June 9th, 2010|Uncategorized|

In today’s complex IT environments, server virtualization simply makes sense. Redundant server hardware can rapidly fill enterprise datacenters to capacity; each new purchase drives up power and cooling costs even as it saps the bottom line. Dividing physical servers into virtual servers is one way to restore sanity and keep IT expenditures under control.

With virtualization, you can dynamically fire up and take down virtual servers (also known as virtual machines), each of which basically fools an operating system (and any applications that run on top of it) into thinking the virtual machine is actual hardware. Running multiple virtual machines can fully exploit a physical server’s compute potential — and provide a rapid response to shifting datacenter demands.

The concept of virtualization is not new. As far back as the 1970s, mainframe computers have been running multiple instances of an operating system at the same time, each independent of the others. It’s only recently, however, that software and hardware advances have made virtualization possible on industry-standard, commodity servers.

In fact, today’s datacenter managers have a dizzying array of virtualization solutions to choose from. Some are proprietary, others are open source. For the most part, each will be based on one of three fundamental technologies; which one will produce the best results depends on the specific workloads to be virtualized and their operational priorities.

Full virtualization
The most popular method of virtualization uses software called a hypervisor to create a layer of abstraction between virtual servers and the underlying hardware. VMware and Microsoft Virtual PC are two commercial examples of this approach, whereas KVM (kernel-based virtual machine) is an open source offering for Linux.

The hypervisor traps CPU instructions and mediates access to hardware controllers and peripherals. As a result, full virtualization allows practically any OS to be installed on a virtual server without modification, and without being aware that it is running in a virtualized environment. The main drawback is the processor overhead imposed by the hypervisor, which is small but significant.

In a fully virtualized environment, the hypervisor runs on the bare hardware and serves as the host OS. Virtual servers that are managed by the hypervisor are said to be running guest OSes.

Para-virtualization
Full virtualization is processor-intensive because of the demands placed on the hypervisor to manage the various virtual servers and keep them independent of one another. One way to reduce this burden is to modify each guest OS so that it is aware it is running in a virtualized environment and can cooperate with the hypervisor. This approach is known as para-virtualization.

Xen is one example of an open source para-virtualization technology. Before an OS can run as a virtual server on the Xen hypervisor, it must incorporate specific changes at the kernel level. Because of this, Xen works well for BSD, Linux, Solaris, and other open source operating systems, but is unsuitable for virtualizing proprietary systems, such as Windows, which cannot be modified.

The advantage of para-virtualization is performance. Para-virtualized servers, working in conjunction with the hypervisor, are nearly as responsive as unvirtualized servers. The gains over full virtualization are attractive enough that both Microsoft and VMware are working on para-virtualization technologies to complement their offerings.

OS-level virtualization
Still another way to achieve virtualization is to build in the capability for virtual servers at the OS level. Solaris Containers are an example of this, and Virtuozzo/OpenVZ does something similar for Linux.

With OS-level virtualization, there is no separate hypervisor layer. Instead, the host OS itself is responsible for dividing hardware resources among multiple virtual servers and keeping the servers independent of one another. The obvious distinction is that with OS-level virtualization all the virtual servers must run the same OS (though each instance has its own applications and user accounts).

What OS-level virtualization loses in terms of flexibility, it gains in native-speed performance. In addition, an architecture that uses a single, standard OS across all the virtual servers can be easier to manage than a more heterogeneous environment.

Easier but harder
Unlike mainframes, PC hardware wasn’t designed with virtualization in mind — software alone had to shoulder the burden, until recently. With the latest generation of x86 processors, AMD and Intel have added support for virtualization at the CPU level for the first time.

Unfortunately, the two companies’ technologies were developed independently, which means they are not code-compatible, although they offer similar benefits. By taking responsibility for managing virtual server access to I/O channels and hardware resources, hardware virtualization support relieves the hypervisor of its most demanding babysitting chores. In addition to improving performance, operating systems can run unmodified in para-virtualized environments, including Windows.

CPU-level virtualization doesn’t kick in automatically. Virtualization software has to be written to specifically support it. Because the benefits of these technologies are so compelling, however, virtualization software of all types is expected to support them as a matter of course.

A virtual toolbox
Each method of virtualization has its advantages, depending on the situation. A group of servers all based on the same operating platform would be a good candidate for consolidation via OS-level virtualization, but the other technologies have benefits as well.

Para-virtualization represents the best of both worlds, especially when deployed in conjunction with virtualization-aware processors. It offers good performance coupled with the capability of running a heterogeneous mix of guest operating systems.

Full virtualization takes the greatest performance hit of the three methods, but it offers the advantage of completely isolating the guest OSes from each other and from the host OS. It is a good candidate for software quality assurance and testing, in addition to supporting the widest possible variety of guest OSes.

Full virtualization solutions offer other unique capabilities. For example, they can take “snapshots” of virtual servers to preserve their state and aid disaster recovery. These virtual server images can be used to provision new server instances quickly, and a growing number of software companies have even begun to offer evaluation versions of their products as downloadable, prepackaged virtual server images.

It’s important to remember that virtual servers require ongoing support and maintenance, just like physical ones. The increasing popularity of server virtualization has fostered a burgeoning market of third-party tools ranging from physical-to-virtual migration utilities to virtualization-oriented versions of major systems management consoles, all aimed at easing the transition from a traditional IT environment to an efficient, cost-effective virtualized one.

Integrating Dell EqualLogic SANS with Citrix XenServer

2017-07-27T00:01:11+00:00 May 21st, 2010|Uncategorized|

INTEGRATING DELL EQUALLOGIC SANS WITH CITRIX XENSERVER

VIRTUALIZED STORAGE TO OPTIMIZE THE XENSERVER ENVIRONMENT

Server virtualization can offer strategic value to organizations in a number of arenas. By creating an abstraction layer between operating systems and physical hardware, IT administrators can consolidate server capacity, parcel out computing resources as needed, and streamline system provisioning and deployment, all while improving service levels and network security. Server virtualization also facilitates support for multiple operating systems, broadened choices among vendors and solutions, and employee empowerment across organizations, regardless of location.

In implementing virtualization solutions, however, IT managers often overlook a major opportunity: the integration of the virtualization platform and the shared storage backend. The result of this oversight: two critical components that effectively operate as discrete silos, creating new inefficiencies and increasing administrative workloads.

SAN AND SERVER MANAGEMENT VIA A SINGLE CONSOLE

To address this problem, Citrix and Dell have introduced the next generation of virtualization and storage with the Citrix XenServer Adapter for Dell EqualLogic PS Series SAN arrays. Available as part of Citrix XenServer 5.0 Dell Edition, this module allows IT administrators to hand off storage virtualization operations from the server virtualization software over to the EqualLogic SAN, for effective handling and superb overall performance.

The adapter integrates EqualLogic control interfaces directly into the XenCenter Management Client, helping improve overall system performance, enabling more efficient disk utilization, and realizing more completely the benefits of storage consolidation. The integration also leverages the automated features designed into both the XenServer and the PS Series arrays, reducing administrator workloads and increasing efficiency over more conventional, stove-piped deployments. 

Through this partnered integration, Dell and Citrix offer organizations the full benefit of virtualization, including centralized storage, live migration, high availability, realtime streaming and improved management of workload and life-cycle costs.

VIRTUALIZED STORAGE FOR THE VIRTUALIZED ENVIRONMENT

With their ease-of-use, storage virtualization, and automation features, EqualLogic SANs provide a flexible means for managing storage resources, gracefully scaling, and reducing overall complexity, resulting in low total costs of ownership (TCO). When deployed within a XenServer environment, EqualLogic SANs can simplify the tasks and routines by which applications and data are stored and protected. Unlike other SAN platforms, the EqualLogic PS Series arrays share processor and storage resources dynamically, and perform load-balancing continuously, allowing more efficient implementation of these vital resources.

The Citrix XenServer Adapter for Dell EqualLogic capitalizes on this intelligence and goes even further, allowing simple management of these resources — storage provisioning, intelligent backup, rapid recovery, and capacity growth — live in production environments, with no application interruption or downtime. The XenServer Direct Storage Adapter enables IT administrators to perform unique EqualLogic capabilities through the Citrix XenCenter Management Client, automating the creation and assignment of dedicated storage volumes to each Virtual Machine (VM), without the manual work required by classic direct-storage mapping technologies.

As an integrated virtualization solution, XenServer and EqualLogic maintain high operating efficiency by delegating such advanced capabilities as Thin Provisioning, Fast Cloning, and Automated Snapshots to the EqualLogic SAN. Thin Provisioning helps IT administrators control costs by dedicating only the storage capacity needed in the short term, and maintaining unallocated storage in a common pool for later use by applications or user groups as disk resources are actually consumed. Fast Cloning lets storage administrators create copies of entire volumes (e.g., virtual drives or LUNs) as a background process, without disrupting network operations. Once created, clones can be used to accelerate the provisioning and deployment of standardized VMs, as well as to test new applications, configurations or procedures. Snapshots are space-efficient, point-in-time captures of storage volumes that can be created without disrupting network operations, for use in backing up or testing data.

In addition, XenServer supports iSCSI multipath I/O (MPIO) and simplified disaster recovery, two strategic tools for improving business continuity even in the event of network failures or other outages. MPIO support allows multiple networkpaths — e.g., separate subnetworks or VLANS — for both the SAN arrays and the virtualization servers, as a means of both improving performance and safeguarding against Ethernet switch failures or other network problems. Disaster recovery tools apply snapshot and fast cloning technologies to the processes of initial VM placement, the real-time movement of VMs via XenMotion, and automatic high availability.

CITRIX XENSERVER DELL EDITION: A POWERFUL VIRTUALIZATION SOLUTION

Dell and Citrix have partnered to bring virtualization ready platforms for today’s dynamic and growing data centers. With the 64-bit open-source Xen hypervisor at its core, Citrix XenServer Dell Edition is a powerful virtualization solution that enables efficient resource consolidation, utilization, dynamic provisioning, and integrated systems management. XenServer Dell Edition has a small footprint and is optimized to run from an internal flash storage in Dell PowerEdge servers.

EqualLogic SANs deliver the benefits of consolidated networked storage in a self-managing, iSCSI storage area network that is affordable and easy to use, regardless of scale. By eliminating complex tasks and enabling fast and flexible storage provisioning, EqualLogic solutions can reduce the costs of storage acquisition and ongoing operations.

Citrix XenServer Dell Edition is certified and fully supported by Dell for select server and storage configurations. Citrix XenServer Dell Edition comes pre-installed with Dell OpenManage Server Administrator, which enables systems management right out of the box without any additional need to install an agent on the host.
