So I was wondering how the rest of you handle the size requirements of larger guests.

Say you have a virtual machine that is going to be bigger than 500 Gb.
Do you still think its a candidate for virtualization?
- What happens when they request addtional space?
- - You will need at least a 1 TB drive, but now it becomes cumbersome to manage?
- - sVMotion and tasks like this become time consuming.
- - RDM's? Suggest to move physical with SAN attached storage?

In what ways are you handling the large disk requirements of some guests?
Curious minds want to know.

candidacy depends a lot on policy, is it more important to virtualize? or more important to save $? luckily in our case, it's more important to virtualize.

- Additional space issues largely depend on the operating system. With Linux like operating systems; additional disks can be added and moved in utilizing LVM. With Window's based operating systems it can become quite cumbersome Sad But here, we just add another virtual disk or expand their current disk (providing there is enough free space on the lun to accommodate their needs)

We have several "large" guests; we use standard virtual disks instead of RDM's.

Also in several circumstances, we have been forced to use extents in order to provide large virtual disks to the guest(s).
