VMware Fusion reaches RC1
106088
(InfoWorld) - VMware launched the RC1 (first release candidate) of its Fusion virtualization software that lets Mac owners run Windows on Intel-based machines, one of the last steps toward finalizing its rival to Apple's own Boot Camp and Parallels's flagship virtual machine, Parallels. Fusion RC1, which can be downloaded free of charge from the VMware site, is "feature complete," said VMware. Among the changes since Beta 4, which was released last month, is "Unity" support for Windows Vista, Windows Server 2003, and the 64-bit edition of Windows XP. Unity lets users run Windows applications directly from the Mac desktop without actually launching into a Windows VM (virtual machine); the previous version of Fusion only offered Unity support for Windows XP. VMware also cited RC1 improvements to Boot Camp VM performance, faster resume from the Mac's suspend state, numerous bug fixes and "experimental" support for the developer's edition of Mac OS X 10.5, a.k.a. Leopard released by Apple at last month's Worldwide Developers Conference. Fusion is on track for a final release next month, said VMware. Until then, it will continue to sell the VM software at the preorder price of $39.99; when the product ships, it will retail for $79.99. VMware's competitors include Apple, which currently gives away the dual-boot utility Boot Camp and plans to integrate it in Mac SO X 10.5 Leopard, due to ship in October; and Parallels Desktop for Mac, Apple-sanctioned VM software that shipped in Version 3.0 several weeks ago.

InfoWorld - In 2006, many enterprise IT groups saw the potential in virtualization, rushed to consolidate servers and subsequently propelled&#160;VMware&#160;software to a market-leading spot. As 2007 begins, VMware&#39;s prices are under attack, just as more CIOs look to virtualization to control server and storage sprawl and tame data center power costs.

(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) - Like other adopters of server virtualization, Purdue University was concerned that its datacenter would hit the wall, exceeding physical space, power, and cooling limits. The use of EMC VMware let it combine 140 physical servers into three Hewlett-Packard DL-585 servers, a 40:1 compression ratio, says Mike Rubesch, director of IT infrastructure systems. "It helps postpone the inevitable," he adds. But the first servers chosen had very low utilization -- around 5 percent -- so the 40:1 rate is not sustainable. Over time, Rubesch expects the ratio to be 6:1, taking into account such servers as e-mail, database, and telephony that cannot be virtualized. That utilization rate will still reduce overall power usage to 16 percent of what it had been and physical space needs to a tenth, as the use of blade servers plus virtualization greatly reduces the physical footprint. Facilities costs should fall by $75,000 per year and hardware costs by $250,000 per year, he says. But organizations considering the use of virtualization need to be careful calculating costs, Rubesch cautions. If you have fewer than 10 virtual server instances running on a physical VMware server, virtualization becomes "extraordinarily expensive," he says. IT managers must also be careful not to factor in too much savings for the operating systems and applications running in virtual machines, Rubesch says. Many IT managers count on being able to run multiple instances of an OS or an app on one CPU, paying for just one license, because most enterprise apps are licensed on a per-CPU basis. But vendors are starting to charge per instance, not per CPU. For example, BEA now charges per instance rather than per CPU for its WebLogic server, and Microsoft Windows Server Enterprise Edition's license allows use on one physical server and as many as four VMs on that server. As virtualization grows more popular, you can expect the licensing savings to evaporate, so the investment should be based on savings elsewhere, such as in hardware and facilities efficiencies, Rubesch says. The use of VMs also increases your risk, because "you can put a lot of eggs in one basket," Rubesch says. But because you've reduced the number of points of failure, IT staff has more capability to focus on those critical areas, he notes. Rubesch is building sufficient capacity so that no single server is fully utilized, providing space for EMC's VMotion software to move VMs if a physical server fails. He's also keeping a spare physical server ready to go if needed. Using virtualization also incurs a high up-front cost. "The benefits aren't immediate," Rubesch says. A big reason is that to use the EMC VMotion utility to move server instances to other physical servers for better load-balancing or failover requires that all the hardware use the same CPU family, requiring a big hardware cost at each refresh cycle. "You need to sell that concept a little bit," he says dryly. Beyond the hardware costs, the use of virtualization makes the server environment more complicated, as "servers" can reside anywhere and change where they reside over time. As a result, "you need more skills," Rubesch says. For example, although a good Windows administrator will easily adapt to running virtualized Windows servers, you still need a dedicated person to handle such items as dynamic allocation and failover, he says. Of course, you can also use virtualization to simplify your environment, Rubesch notes, such as having standard server images that ensure consistency -- ending the nightmare of navigating the peculiarities specific to each hand-deployed physical server. "It's a lot simpler with VMs to have them nearly identical." Despite the caveats on understanding actual savings and the increased up-front costs, Rubesch is a big fan of server virtualization: "You get real benefit from it -- as long as you plan ahead."

(InfoWorld) - The president of virtualization software leader VMware Wednesday questioned the strategy of rivals that are integrating virtualization functionality into their operating systems. Diane Greene made the comments at the third and final day of the Morgan Stanley Technology Conference in San Francisco. VMware, a subsidiary of storage vendor EMC, doubled revenue in EMC's latest quarterly report, compared to the year ago quarter, as enterprises embrace VMware's virtualization software to make more efficient use of the servers in their data centers. RivalsÂ like Red Hat and Microsoft have responded to VMware's dominance by integrating virtualization into coming new operating systems. Red Hat is introducing Red Hat Enterprise Linux 5 next week, and Microsoft's new Windows server OS is due later this year. But Greene, in discussing virtualization with analysts for the investment firm, said she wonders how effective the competition's virtualization features can be. "Traditionally, the operating system manages the hardware and manages the application. Once you virtualize with a hypervisor, that is now what is managing the hardware, not the OS," Greene said, in a presentation that was distributed via webcast. "Now the operating system is just managing the application. So certainly Windows and Red Hat are moving to integrate virtualization into their OS, but part of the value proposition seems to be lost when you do that." Spokespeople for Microsoft and Red Hat did not respond to requests for comment. VMware is a strong contributor to the earnings of parent company EMC, which also sells storage hardware and security software. Greene also is executive vice president of EMC. Revenue for VMware increased to $232 million in the fourth quarter of 2006, 101 percent more than a year prior. The growth comes from increased demand for VMware Infrastructure 3, a virtualization software suite for servers and storage networks. VMware's growth prompted EMC to recently announce plans toÂ spin off 10 percent of VMware in an IPO. EMC executives said they anticipate releasing the prospectus later this month for the IPO, expected about midyear. Greene noted the stock sale will benefit VMware employees as well as potential shareholders. "Our stock-based compensation will track our performance, and that is the ideal model," she said. Also at the Morgan Stanley conference, Greene acknowledged that virtualizing servers, which helps them use more of their designed capacity, may suppress server sales growth. But she said many customers are upgrading servers as they introduce virtualization into their operations. Those new servers are more high-end products, with greater processing power, and should yield higher margins for server vendors. EMC reported fourth quarter 2006 financial results Jan. 23, posting net income of $389 million, or $0.17 a share, on revenue of $3.21 billion. It edged out analysts' estimates of $0.16 a share. Â
