IBM has added a new capability to its virtualization platform that will allow Linux applications to run on IBM&#39;s Unix servers, the company announced Tuesday.The &quot;Lx86&quot; capability, to be included in IBM&#39;s PowerVM virtualization software, allows x86-based Linux applications to run on IBM&#39;s System p and Power-based Unix systems without modification, according to IBM. The systems will automatically detect and run Linux-based binaries designed for x86 environments.&quot;Lx86 is a way to say, &#39;Whatever you have, it can run,&quot; said Scott Handy, vice president of marketing and strategy for IBM Power Systems.The capability will simplify the consolidation of Unix and Linux server sprawls, Handy said. Running Linux applications in the Unix environment can reduce the cost of server consolidation and energy consumption and increase asset utilization, he argued.Lx86 will be a useful tool for people looking to migrate from Linux systems to other IBM systems, IBM said. The company offers both Unix and Linux operating systems on its servers.The capability will be included in all editions of IBM&#39;s PowerVM platform, which it also renamed Tuesday from the Advanced Power Virtualization platform.The software now includes an Express edition targeted at SMBs. It allows customers to create up to three partitions on a server and control the use of processor cycles to get optimal performance. The Express edition will be shipped to customers soon, priced at $40 per core. PowerVM is also available in Standard and Enterprise editions.IBM also announced that it will update its i5/OS operating system with support for Power6 processors. The update, called V6R1, includes improved performance, storage and security features, according to IBM.The update supports IBM&#39;s Power6 EnergyScale technology for controlling energy use. The company also updated its Rational software tool set for the i5/OS, Handy said.The i5/OS V6R1, for IBM&#39;s System i servers, will ship in March. It will also work with the company&#39;s new BladeCenter H server chassis, Handy said.

(InfoWorld) - In 2006, many enterprise IT groups saw the potential in virtualization, rushed to consolidate servers and subsequently propelledÂ VMwareÂ software to a market-leading spot. As 2007 begins, VMware's prices are under attack, just as more CIOs look to virtualization to control server and storage sprawl and tame data center power costs. For starters, VMware rivals XenSource and Virtual Iron Software have launched new open-source alternatives, undercutting VMware on price. Also, new processors, such as IBM's Power 5 and upcoming Power 6 chips, and new operating systems have virtualization capabilities built in, negating the need for some additional software, says Clay Ryder, president of The Sageza Group. Sun Microsystems' Solaris 10 OS includes a virtualization feature it calls Containers. MicrosoftÂ is expected to release a beta version of Windows Virtual Server in the first quarter of 2007 and ship it a year later. That's good news: As virtualization features become part of the hardware or the OS, software providers will have to offer useful extra features, Ryder says, such as automated new software testing or security patch management. Virtual Iron introduced Version 3.1Â of its virtualization platform in December for a license price of $499 per socket--compared to $2,875 per socket for a comparable VMware license. XenSource also introduced new virtualization products at sub-$1,000 prices. Both XenSource and Virtual Iron build their proprietary products on top of the open-source Xen platform for virtualization hypervisors. (A hypervisor lets a computer run multiple operating systems at once.) VMware's products are not based on open source. Meanwhile, middleware vendor BEA Systems is making its own cost-cutting move. In the first half of 2007,Â BEA plans to releaseÂ WebLogic Server Virtual Edition (WLS-VE), a version of its Java application server that includes Liquid VM--a BEA-specific Java Virtual Machine that lets Java applications run directly on a hypervisor without requiring an operating system to be present. This will let users substantially reduce the amount of computer power, lowering the hardware costs per application, says Guy Churchward, vice president and general manager of the Java Runtime Products Group at BEA Systems. Initially, Liquid VM will work only with VMware's ESX Server hypervisor. Analysts advise CIOs planning for virtualization in 2007 to think strategically, not just tactically. "To really make virtualization work you want to do it so end users access capability, not just specific machines," Ryder says. "That's only going to be possible if you take a strategic approach," he says, noting that virtualization needs to be applied to storage, networking and the introduction of new software, not just servers. Mike Williams, CIO for the Defense Contract Management Agency (DCMA), learned a lesson about thinking strategically when he did a virtualization project in 2006. (The DCMA, a federal Department of Defense agency, places contract managers inside companies fulfilling defense contracts for weapons systems, jets, military equipment and parts.) Williams deployed VMware, reducing the agency's number of servers to 160 from 560 and the number of data centers to three from 17. But that move taxed the WAN when all the network traffic converged on the three data centers. His advice: Optimize the WAN first. Still, Williams likes the results. Before virtualization, DCMA replaced about one-third of its 560 servers annually at a cost of about $2 million, Williams says; virtualization cut that expense to $560,000.

(InfoWorld) - While many IT shops see virtualization as a question of adopting EMC's VMware on servers running Windows or Linux, Nationwide Insurance has adopted the technology for both x86-based and mainframe-hosted servers. After all, notes Buzz Woeckener, the company's zLinux/Unix server manager, virtualization was invented for mainframes. On the x86 server side, Nationwide reached 5,000 servers two years ago, running all sorts of departmental applications, notes Scott Miggo, vice president of technology solutions. "We were growing at a steady pace, so we wanted to control the server space and the costs for new development," he says. "A lot of our servers had only a 10 percent utilization rate," he notes, wasting much of the server capacity. Roughly half are production application servers and half are test-and-development servers. Today, there are 3,500 physical servers in operation but still 5,000 instances under management. The VMware servers typically host a dozen instances per physical server. "We assume every new server or application can be virtualized," Miggo says. He expects to have more than 1,000 virtual servers running on 89 physical servers by 2009. His team works to tweak I/O requirements or settings for virtual servers that may have trouble supporting I/O needs in their default state, and it works with vendors to support VMs where possible, before falling back to dedicated servers. Lotus Notes and database applications are examples of where the I/O requirements make virtualization not an option. Although it's easier to deploy servers in a virtual environment by using predefined images, "our staffing has stayed pretty much the same," Miggo says, because the same number of servers must still be monitored. The slight reduction in management overhead is offset by the need for VMware experts to manage the VMware environment, in addition to the server instances. And Nationwide learned the hard way that it needs to monitor both its virtual and physical servers, then correlate the two to identify potential trouble spots, Miggo says. Not doing so can make diagnosis hard, since a VM issue may be caused by a physical issue that a server monitor application running in only the VM won't detect. There's also more overhead needed for Miggo's shared-services group to coordinate all users (such as developers and application managers) of a physical server, as changes to the physical server could affect them all -- and because adjustments to one VM's application mix could affect I/O and other physical server performance characteristics. "We now have to coordinate with 12 users," Miggo says. "People were used to having their own boxes and doing their own thing. Now they're more tightly controlled, which they don't like. But they have to follow control processes like code management and release management since what they do could affect others," he notes. The use of EMC's VMotion software to load-balance and failover VMs across physical servers might reduce management, but the insurer is still exploring that technology. One barrier: Its requirement that all server instances run on physical servers with the same CPU family, requiring a consistent server pool to be in place. Nationwide runs its Web servers in a zLinux environment on IBM zSeries mainframes, supporting 650 guest operating systems (VMs) today, with space for another 650 before additional hardware frames would be needed. Often, using z/VM to support the virtualized Web servers requires a different strategy than using VMware to support virtualized Windows servers, Woeckener notes. For example, you might add memory, CPUs, or network cards to increase I/O on a VMware server. On a zSeries, the CPUs just handle executables, offloading physical I/O (such as network bandwidth and resource scheduling) to dedicated processors, so you don't need to worry about performance-sapping overhead incurred by server resource management. Another difference: Increasing heap size can improve performance in a Windows application but also degrade it in a zLinux application, Woeckener says. That's because Linux steals resources wherever it can find them, so any extra heap space is used by Linux for its own purposes, degrading application performance. When the heap size is reduced, Linux seeks resources elsewhere, giving the full heap to the application and improving performance. In both the VMware and z/VM environments, the ease of deploying new virtual servers has led Nationwide to align demand with real needs, as well as to encourage the use of VMs rather than physical servers. Virtual Windows servers cost a requestor $750 per month versus $2,000 per month for a physical server. And zLinux VMs add a per-MIP rate for weekday usage exceeding 15 MIPs. This overage charge steers batch processing to overnight and weekend periods, when overall demand is less, and forces developers of applications in use during the business day to optimize for performance, saving datacenter resources at the same time.

(InfoWorld) - Going virtual is becoming a real answer for data center managers, according to a survey of large and small businesses. Fifty-one percent of North American companies are either testing virtualization technology in their data centers or have already deployed it, according to a report released Friday by Forrester Research. Use of virtualization is less in Europe (35 percent either testing or deploying it) and Asia-Pacific (21 percent), but is generally growing nonetheless. Forrester compared results of a 2006 survey to a similar one in 2005 in which 41 percent of companies in North America, 30 percent in Europe and 23 percent in Asia-Pacific were using or testing virtualization. Although the Asia-Pacific number is lower in 2006 than 2005, Forrester notes the survey sample was smaller there than in the other regions. Whether or not they are using virtualization, interest in or even just awareness of virtualization grew in all geographic regions in 2006 from 2005. Virtualization refers to dynamic management of a company's total information technology infrastructure. The most common use of virtualization is in the operation of x86 servers in data centers. Virtualization makes it possible to run multiple software applications and operating systems simultaneously on one physical server. The result is that instead or running at only 15 percent to 20 percent of capacity, when one server runs only one application, servers can run at 80 percent to 90 percent of capacity. Thus, a company could spend less money buying servers. Although virtualization is more likely embraced by large enterprises, awareness of it by SMBsÂ is growing at a faster rate, the survey showed. Awareness of virtualization by Global 2000 large enterprises grew to 92 percent in 2006 from 87 percent in 2005. But awareness by medium-to-large business jumped to 86 percent from 60 percent andÂ to 83 percent from 62 percent by SMBs. Server virtualization software company VMware remains the dominant provider. Fifty-three percent of those surveyed would consider VMware for virtualization, versus just 9 percent for Microsoft's Virtual Server product. Only one respondent mentioned the open-source Xen virtualization software as a choice, while just six mentioned Sun's Solaris operating system, whose virtualization feature is called Containers. EMC, which operates VMware as a subsidiary,Â announced plans this week to launch an initial public offering of VMware stock. Microsoft, which introduced its Virtual Server product in 2004, is expected to launch an updated version later this year. Forrester surveyed 1,267 enterprises with more than 1,000 employees, and 503 SMBs with 100 to 999 employees for its report.

(InfoWorld) - Hewlett-Packard is upgrading its virtualization software offerings to help data center managers better manage their virtual environments, while VMware is offering a virtualization capability for Web hosting companies. HP on Wednesday announced enhancements to its HP Virtual Server Environment software for its Integrity line of servers, which creates a pool of virtual servers that can expand and contract depending on capacity needs. Virtualization refers to the practice of running multiple software applications on one physical server to enhance utilization. Previously, most servers were dedicated to running only one application, but that kept utilization rates as low as 15 to 20 percent. Virtualization increases server utilization, thus reducing the need to buy, power, cool, and manage additional servers. HP also offers a specific software tool, Integrity Essentials Capacity Advisor, for easing the migration of data from Sun servers to HP servers. Although virtualization improves server utilization, it requires different management tools than a nonvirtual environment. HP says the Integrity Essentials Global Workload Manager, another feature of Virtual Server Environment, specifies which computer workloads can automatically access available capacity in order to maintain service level agreements for key applications. The company also announced a new Partner Virtualization Program, which allows ISVs to test how their software will work in an HP virtualization environment. Testing and fine-tuning can be done for virtualization using HP ProLiant and Integrity servers and with a number of operating systems, including HP-Unix, Windows Microsoft, and Novell and Red Hat Linux. The Virtual Server Environment also works with VMware virtualization software. Meanwhile, VMware announced Wednesday the launch of its VMware Service Provider Program, which allows Web hosting services, telecommunications companies, and other outsourcing businesses to include virtual infrastructure as a service offering. Traditional hosting services use dedicated servers for each client, but virtualization makes it possible to run multiple virtual servers, even for different clients, on one physical server. The Web hosting company can then bill clients monthly based on how many virtual machines they use, not physical ones, VMware said.
