How much drive space can I use on a single server with vmware 5?

I know that in Vmware esxi 4 I was only able to use a 2TB raid. With vmware 5 what is the limit? I plan on buying the V5 ESSENTIALS PLUS KIT 3HOST MAX 2CPU PER HOST AND 192GB VRAM product and then using one of the servers to backup the other two offsite with Veeam. I want to make sure I don't have a drive problem. I also have offices with vmware that I want to back them up to one central server in a colo.

Thanks,

64TB is the maximum size of a VMFS datastore.
a VMFS can be up to 64TB in Vsphere 5

with ESXi 4.1 you can use extents to join 2TB datastores together.

Make sure you use VMFS-5 and not 3 in vSphere 5.0

64TB is the max, but the disk size for your VM is still 2TB max. You can of course create Dynamic disks (in Windows) & extend them out to a partition of > 2TB, though.

Ok. A little confused. I see the 64TB, but what is the 2TB disk size limit of the VM? If I have a server with ten 600gig SAS drives, can I create a RAID that is over 2TB and then create a server with over 2TB of drive space?

virtual machine disk is still limited to 2TB.

NO. Max size of virtual disk is still 2TB.

do not get confused here between ESX host datastore Max 64TB

VMware ESX Guest MAX virtual disk size 2TB, which is stored on the datastore.

Yes...very confused. As an example if I had a "physical" server. BIG Raid 5 with 3TB of storage then that is fine. But if I install a 2008 virtual server and give that server 2.5tb of drive space over the c and d partitions, I can't do that?

That is correct, because the maximum virtual disk is still 2TB.

if you wanted to create a virtual disk larger than 2TB you would need to use OS techniques to span disks, or present a RDM to the OS, or an iScSI LUN.

There was a lot of info scattered on replies but they gave me the full explanation. The 64TB host and 2TB VD was a little confusing at first but they clarified.
