the limit is not based on OS but rather ESX
the largest virtual disk size in 5.5 and above is 62tb

Hello,

The maximum size that you can use in a virtual hard disk is 62 TB.

From the article, "You must use the vSphere Web Client to create or extend a VMDK beyond 2 TB".

Any screenshot or reference on how to configure it ? Thx

and if the disk is less than 2TB currently, it will need to be reformatted as GPT if you go above 2TB under NTFS!

and although the host may be able to provide a 62TB disk under VMware ESXi 5.5., which has already been posted twice, Microsoft have only tested up to 16TB, based on this link

My current Window 2008R2 disk is configured as picture01. Should I expand the disk in vmware client or web interface (picture02 / picture03) ? Do I need to shut down the server and the option is currently grey out ?

This looks like an Exchange disk.

To be honest with you I would create and add a new disk...of the size you require, larger than 2TB...

format as GPT in the OS, and then use Exchange to MOVE to Mailbox and Storage Group to this new disk, and then eventually remove and delete the old 2TB disk.

That's better and recommended, because you can do all that with VM running.

otherwise you are going to have issues.

Also that disk has a snapshot attached which you need to deal with (new question!)

"format as GPT in the OS" - Does only GPT support disk space larger than 2 TB ?

Thx

correct.
AXISHKAuthor Commented:
One more check, once I format the new disk as GPT, can I latter expand the disk through picture02 or picture03 ? Does it support online disk expansion ?
