I get asked this question many times… what are the best practices for partitions with ESX 3.5.
Here are the settings that I use…
Setting primary partitions
Best practices state that the following partitions should be made “Primary” partitions:
Table 3 – Primary Partitions
Mount Point Partition Type Size in MB
/boot ext3 100 MB
/ ext3 2048 MB
N/A swap 1600 MB
This can be accomplished by selecting each of the aforementioned partitions (one at a time) and clicking the “Edit” button. The configuration options for that partition/file system will be brought up. Select (turn on) the checkbox option near the bottom of the box labeled “Force to be a primary partition”. Do this for each of 3 file systems listed above, clicking “OK” after fixing each file system.
The following table adheres to VMware best practices:
Mount Point Partition Type Size in MB
/var ext3 4096 MB
/tmp ext3 1024 MB
/opt ext3 2048 MB
/home ext3 1024 MB
vmkcore 100 MB
N/A vmfs Remaining space
Check out this great article on EVC… lots of great information and links!
VMware KB: Enhanced VMotion Compatibility (EVC) processor support: “Enhanced VMotion Compatibility (EVC) processor support
Enhanced VMotion Compatibility (EVC) simplifies VMotion compatibility issues across CPU generations. EVC automatically configures server CPUs with Intel FlexMigration or AMD-V Extended Migration technologies to be compatible with older servers. After EVC is enabled for a cluster in the VirtualCenter inventory, all hosts in that cluster are configured to present identical CPU features and ensure CPU compatibility for VMotion. The features presented by each host are determined by selecting a predefined EVC baseline. VirtualCenter does not permit the addition of hosts that cannot be automatically configured to be compatible with the EVC baseline.”

Shadow Protect IT Edition is a product that I love to use… especially for P2V (Physical to Virtual) conversions..
Benefit that I found are:
It allows you to create an image of a server, PC, notebook, etc and then push it to anything you want..
PC to Notebook, server to VM, VM to server, PC to VM, etc..
I keep every image file that I make… this comes in handy after a P2V as sometimes the applications owner wants to see there system prior to the P2V.
I simply get a piece of hardware, push the image, and let them have it..
Also, I can mount the image file and give them access as a file share..
