14.11. Solutions Fast Track

14.11.1.

14.11.1.1. Evolved Virtually You Have Become
The road ahead involves constant learning, something which you should embrace.
You've already taken the first steps to a virtual infrastructure. As you continue forward, you'll find ever-increasing options and possibilities, and you'll certainly want to virtualize what you can in your environment.
The further you move down the path of virtualization, the greater the rewards. Buzzwords like ROI and TCO will actually become meaningful.
14.11.1.2. Bigger and Badder Brains
Virtual machines perform better with more memory.
Sixty-four-bit processing and the increased capacity for memory inherent with this technology will elevate virtual possibilities far above today's levels.
From a memory perspective alone, 64-bit computing is a technology that will greatly enhance consolidation ratios.
14.11.1.3. ESX Server 3.0…Better the Beta
VMware needs to expand its beta program and be more inclusive instead of exclusive.
We've heard rumors that ESX Server 3.0 may be based on the 3.0 Linux kernel.
We've also heard that it will come with metadata enhancements, new operating system support, 64-bit support, four-way virtual-SMP, improvements in SAN storage, and iSCSI support.
14.11.1.4. Faultless Fault Tolerance
With each release of ESX Server, support for clustered virtual servers has increased.
In the past VMware tried to show nearly equal support between the SAN manufacturers, so you can bet that new and interesting fault-tolerant solutions will become available
A cost-effective transport for storage supported by VMware would definitely open up more possibilities for virtual infrastructures.
14.11.1.5. The Rise of Utility Computing
With VirtualCenter, all of your ESX Servers are basically one pool of resources, CPUs, disks, memory, and so on.
With the use of VMware's SDK, the possibilities of utility computing become closer and closer.
Some interesting technologies exist in VMware's ACE product, such as expirations and policy-based virtual machines that if applied to some future version of ESX Server would allow for tremendous utility computing and server provisioning capabilities.
14.11.1.6. Your Moment of Xen
Xen is a growing virtualization platform that is gaining industry support. Keep your eye on it.
According to the XenSource site, currently Xen only supports some Linux and does not support any Windows virtual machines.
The recent release of SUSE 9.3 comes with the most current release of Xen built into it.
14.11.1.7. Microsoft Virtual Server…Watch Your Six
Microsoft's virtual platform is a decent one on which to run Microsoft operating systems. Although the product and its support isn't that old, Microsoft has always found a away of catching up. So definitely keep your eye on it.
Microsoft Virtual Server and VMware's GSX, as well as the virtual machines, run as processes within the host operating system.
Although the product and its support aren't that old, Microsoft has always found a way of catching up. So definitely keep your eye on it.
14.11.1.8. Virtual Storage Is the Place to Live
If you have a SAN, great. If not, try to budget for one. A SAN is where you want your virtual machines to live.
Vmotion requires a SAN, and quality SANs provide stellar redundancy and availability.
With some clever scripting, you can get some of the benefits of a SAN, such as snaps and BCV-like restore possibilities, even though you still don't have Vmotion.
