Gabes Virtual World

I frequently read postings on different forums about what the best LUN size is and I thought I’d write a post about it on how I usually do it.

First of all, there is no ideal LUN size that suites all environments. But I think there is a general calculation you can use to come to the LUN size suited for your environment.

What’s New in VMware Workstation 6.5:

• Use Unity to integrate your guest apps with your host
• More Powerful VM Record and Replay
• Support for Smart Cards & Smart Card Readers
• Enhanced ACE Authoring
• Link State Propagation Networking
• Improved 3D graphics Support

To make sure my ESX hosts are VMotion compatible, I normally use the cpuid.iso found on the ESX install CD, to boot from and write down all cpu info. Its a bit of a pain, because you can’t redirect the output to file or floppy, so you really have to write it down on a piece of paper.
