Blades have come a long way since the early days of very few options and limited expandability. Most early blade servers only had one or two NICs, limited storage, no Fibre Channel support, and limited CPU and memory, which made them poor choices for virtual hosts. That’s all changed in recent years as blade technology has evolved and no longer has the limitations of earlier blades, making them ideal for virtual host servers. Modern blade servers can support up to 16 NICs, four quad-core processors and multiple Fibre Channel or iSCSI HBA adapters. When considering blade servers in your environment as an alternative to traditional rack mount servers, you need to know the advantages and disadvantages of each and why you might choose one type over another.
Some reasons you might choose blade servers over traditional servers:
- Rack density is better for data centers where space is a concern. Up to 50% more servers can be installed in a standard 42U rack compared with traditional servers.
- Blade servers provide easier cable management as they simply connect to a chassis and need no additional cable connections.
- Blade servers have lower power consumption than traditional servers because of reduced power and cooling requirements.
- Blade servers can be cheaper than traditional servers when comparing a fully populated chassis with the equivalent number of traditional servers.
Some reasons you might choose traditional servers over blade servers:
- Traditional servers have more internal capacity for local disk storage. Blade servers typically have limited local disk storage capacity due to the limited drive bays. Some blade vendors now have separate storage blades to expand blade storage, but this takes up additional slots in the blade chassis.
- Traditional servers have more expansion slots available for network and storage adapters. Blade servers typically have very few or no expansion slots. Virtual hosts are often configured with many NICs to support the console network, vmKernel network, network-attached storage and virtual machine networks. Additional network adapters are also needed to provide failover and load balancing.
- Once a chassis is full, purchasing a new chassis to add a single new additional server can be costly. Traditional servers can be installed without any additional infrastructure components.
- Traditional servers are often less complicated to set up and manage than blade servers.
- Traditional servers have multiple USB ports for connecting external devices and also an optical drive for loading software on the host. They also have serial and parallel ports, which are sometimes used for hardware dongles for licensing software. Additionally, tape backup devices can be installed in them. Blade servers make use of virtual devices that are managed through the embedded hardware management interfaces.
Many people that use blade servers as virtual hosts often take advantage of the boot-from-SAN feature so they don’t need internal storage on their blade servers. The choice between blade and traditional servers often comes down to personal preference and what type of server is already in use in your data center. Some people like blades, others don’t. Regardless of which server type you choose, they both work equally well as virtual hosts.
Having a virtual machine expiration date is an important procedural step in successfully managing a virtual environment. Managing the expiration date in VMware environments is challenging without adding pricey tools such Lifecycle Manager or other commercial management products. In this video blog, Rick Vanover discusses one way to get the expiration date into your virtual environment without adding direct costs:
Vizioncore, the company best known for its virtualization backup software vRanger Pro (formerly known as esxRanger) hoped to make a strong impression at VMworld with lots of new products being unveiled.
On display was the next vRanger release, version 4.0. Highlights of the new release are a faster engine, a redone GUI, more granular file-level recovery and the new vAPI 1.0 that allows third-party software providers to leverage the Ranger technology. Expect to see news about partners writing to the new application programming interface after VMworld, said Chris Akerberg, Vizioncore’s president and COO.
The company has also delved into the virtual sprawl reduction business with the introduction of vOptimizer, a new tool that enables administrators to easily shrink and expand VMware Virtual Machine Disks. The tool targets the masses of overallocated virtual machines and provides an easy alternative to what is otherwise a cumbersome, manual process, Akerberg said.
Last but not least, the company has announced the version 4.0 of vConverter, its physical-to-virtual migration tool. New features include synchronized cutover, continuous protection via incremental replication, automated remote cold migration, task profiles and the so-called Quick Convert feature.
One caveat: While Vizioncore showcased these products at VMworld, the offerings won’t be generally available until later this fall.
With all due respect to VMware’s new CEO Paul Maritz, the portion of yesterday’s keynote discussing VMware’s new vClient initiative didn’t seem to register much with VMworld attendees.
After the address by VMware CTO Steve Herrod, however, was a different story. Assisted by VMware’s Jerry Chen, Herrod and Chen finally got a rise out of the audience, who applauded loudly to a demonstration of 25 virtual machines being provisioned out to thin clients and laptops, then updating the master VM image with Google Chrome using ThinApp.
“I need that right now,” said the attendee sitting behind me at the conclusion of Chen’s demonstration. “Heck, I needed that yesterday.”
I think part of the crowd’s enthusiasm simply had to do with finally “getting it.” Unlike Maritz, Chen used the word ‘hypervisor’ to describe the “thin-client virtualization layer” that drives VMware’s vClient idea of being able to manage disconnected laptops as well as connected VDI thin clients. By saying the H word, 14,000 VMworld attendees had a collective aha moment.
Whatever the case, with vClient, VMware has once again taken a top-down approach, tackling the enterprise’s “desktop dilemma” rather than that of the consumer or SMB. In a subsequent conversation with VMware senior director of product marketing Bogomil Balkansky, he said it’s not that those segments don’t have desktop dilemmas of their own, rather, “the problems of the enterprise are very well identified,” and thus, for VMware, the enterprise is “a much easier entry point.”
Looking out a few years, however, Balkansky described a distinctly consumer-focused scenario. Home users today run full-fledged PCs, complete with a host OS, and all the attending management issues. At the same time, home users engage largely in web-focused activities. “Given that everything I do is Web-connected, why isn’t that part of my DSL service?” Balkansky asked rhetorically.
In other words, Balkansky is insinuating that someday, users’ personal desktops will run as VDI images hosted by the Verizons and Comcasts of the world rather than locally on their home PCs. For a small monthly fee, users will enjoy the convenience of a centrally managed, backed up desktop that they can access from anywhere, and easily recover even if their disk drive fails or laptop is stolen. That’s an idea that just about everyone can get their head around.
On Sept. 17, 2008, SixApart and JumpBox announced the release of a jointly developed appliance named Virtual Movable Type. The product can be installed on a server, PC or in a cloud infrastructure and is compatible with the majority of the major virtualization platforms on the market.
As opposed to installing its predecessor Movable Type on a web server, Virtual Movable Type is installed from software and exists as a single virtual machine (VM) which eliminates the need for configuring all of the applications in the server environment. According to JumpBox CEO Kimbro Staken, “It takes minimal technical skill and just minutes to deploy, regardless of whether it’s on your laptop, in the data center or in the cloud. This strips away the barriers to using server based applications like Movable Type and allows a less technical customer to take advantage of this great software.”

When you walk up to the Venetian Hotel in Las Vegas this week, it is obvious something big is happening, and it sure as hell isn’t me winning the jackpot on those God forsaken slot machines.
When VMware Inc. announced there would be 14,000 people attending VMworld 2008 this week, they weren’t blowing smoke. Last year’s show in San Francisco held about 10,000 attendees and that seemed like a lot. Apparently, that was just the beginning.
The volume of IT administrators who are here in Vegas this week makes me wonder in a slight panic, who is manning all of the servers?
It reminds me of an episode of the cartoon American Dad, where the main character, a CIA agent named Stan Smith, storms into a Sci-Fi convention looking for someone and sees a place swarming with stereotypical techie types. “Good God, who is manning the Internet?,” he gasped.
Joking aside, the not-subtle point I am trying to make is that the huge turnout at VMworld 2008 signals how popular virtualization is today, reminiscent of the earlier days of Linux when LinuxWorld was a huge show.
Though the LinuxWorld organizers claimed there were 10,000 people at the show in San Francisco last month, it didn’t seem that way. “When Linux was an emerging technology that people were excited about, those LinuxWorld shows were like [VMworld] is today,” said AMD’s commercial products director Margaret Lewis. “But now Linux is mainstream, so the excitement is gone.”
She said AMD didn’t set up a booth at the LinuxWorld show floor this year because turnout the previous year was low. And by the way, AMD has a monster booth set up at VMworld this year.
Which means that when virtualization becomes mainstream, VMworld will no longer be “the place to be.” Maybe VMware 2015 will be held at a small conference center in a small state, like Rhode Island (which is great, by the way).
But for now, VMworld Las Vegas is it.
At VMworld 2008, VKernel announced that it will partner with Microsoft to offer several management tools for Windows Server 2008 and Hyper-V. VKernel will modify its line of management tools to better handle Microsoft-based environments.
Although VKernel already supports the majority of VMware platforms, this will be the first foray into tools that are supported for Microsoft Hyper-V. “We see this as an opportunity for VKernel to differentiate ourselves and enable our customers to best manage their environments and assure optimal performance regardless of whether they are using Microsoft or VMware,” VKernel CEO Alex Balkman said in a press release.
Initially only some of the tools that make-up VKernel’s Performance Lifecycle Management bundle will be available for use with Hyper-V. They include Chargeback, a cost analysis tool; Capacity Analyzer which monitors resources; and Modeler which tests new additions to an environment and, prior to launch, analyzes the impact they might have on the environment.

On Tuesday, Sept. 16, Irvine, Calif.- based Integrien Corp. previewed the newest incarnation of its systems management software, Alive, at VMworld 2008. This new release is notable because it contains VMware-specific capabilities for the first time in Alive.
The newest version of Alive can monitor the behavior of VMware ESX servers, clusters and virtual machines (VMs) while providing a picture of the overall health of a VMware infrastructure. It will also contain more in-depth analysis including an overall environment “health” score regardless of whether the infrastructure comprises heterogeneous tools or VMware-only tools. In addition Alive sends an alert to the administrator prior to a problem’s manifestation, along with the root cause, because of its ability to learn the behavior of an environment.
