Hi
A quick question regarding configuration. WHat would be described as the best practice for setting up a guest server which required a large amount of disk space? Which is the preferred option:
1. - Create a VM with a raw device mapping to the LUN (on a san)
or
2. - Create a VM with another large virtual disk which sits in a datastore on the LUN (on a san)
Thanks
Dave
Sincy you're limited with 2TB anyway (except using software iSCSI from inside guest OS), the only arguments are:
1) Use RDM if it is possible that you'll connect to this LUN physical machine. Or you already have LUN from physical machine like a big fileserver.
2) Use VMFS in all other situations - vmdks give you flexibility, you can migrate VM wherever you want.

Cool, as I thought really, Both options are OK, it just depends on how you want to handle it, but using vmdks just gives you a bit more flexibility.
Thanks
