I hear more and more that people say, take a whole enclosure and place everything in a RAID 5 instead of by application look for the best performance. So what is best?

At VMworld Europe, Cannes, France, Citrix Systems Inc. will also unveil a version of Essentials for Microsoft Hyper-V, layering Citrix's management capabilities on top of Microsoft's base hypervisor. Citrix has also elicited promises from Microsoft that System Center will manage XenServer in its next release, which is scheduled for 2010, and that Microsoft will push Essentials for Hyper-V through its worldwide partner network. These efforts may give XenServer a boost in the marketplace and in its competition with VMware.
XenServer's feature shell game
Features in the free XenServer package include the hypervisor with support for Windows and Linux guests, live migration and resource pooling, and unlimited multiserver management. Simon Crosby, Citrix's CTO, compared the features in the newly free XenServer to those in VMware Virtual Infrastructure 3 (VI3) Enterprise Edition, which lists at $5,750 per dual-socket system.But that isn't an accurate comparison, said Burton Group analyst Chris Wolf, since VI3 Enterprise Edition also includes high availability (VMware HA) and workload balancing (Distributed Resource Scheduler), which Citrix includes as part of Essentials.
"HA is the biggest thing that's missing," Wolf said. "If I'm an enterprise and I'm going to deploy in production, [the virtualization platform] has to include HA."
Other features of the erstwhile Enterprise Edition not included in the free edition include Workflow Studio orchestration, for automating common tasks, and StorageLink, a set of storage integration modules that enable administrators, among other things, to provision virtual machine storage directly from the XenServer management console. Both Workflow Studio and StorageLink will be included as part of Essentials for Hyper-V and XenServer.

In addition to providing a hypervisor scorecard, the criteria in the study should be administered by IT as a way of differentiating between true hypervisor features and marketing spin, Wolf said.
"We believe this is the first comprehensive hypervisor comparison study by an analyst firm, and some people - like Microsoft - are not going to be happy with us," Wolf said. Burton Group worked with Global 1000 organizations on the evaluation criteria and analysis of production level hypervisors.
The evaluation criteria
Burton Group scored four products for enterprise production-environment readiness: VMware Infrastructure 3 (VI3), Microsoft Hyper-V, Citrix XenServer and Virtual Iron and scored each hypervisor using several features, including the following:
* high availability;
* live migration;
* memory management;
* networking, storage and security;
* management features and power; and
* licensing and support.

Aaron Sweemer and Dudley Smith from http://www.virtualinsanity.com/ has don a great job by mindmap Troubleshooting ESX.
"I was at the Louisville VMUG on Friday talking about Troubleshooting ESX. In my preparation for the event, I was looking for a good PowerPoint presentation I could reuse and I stumbled across a sweet little gem of a document. Dudley Smith, a VMware Technical Account Manager (TAM) out of Virginia, created a cool one page Mind Map for Troubleshooting ESX. Does it address every potential issue you'll come across? No, of course not. But it's a heck of a good place to start. One look at his Mind Map and I thought to myself, "that would be a great thing to have printed out and hanging over every VMware admin's desk."
