Data space issue - to span or not to span?

We have a HP SAN that has a 2TB virtual disk limit.  

We currently have a 2TB SAN virtual disk (LUN) presented to a Windows 2008 server formatted as a basic partition.  The entire root folder is shared as a network drive.  The issue is that it's almost full and we need to extend it.

What is the best option here?  We were thinking of presenting another 1TB LUN and spanning both partitions to create a 3TB logical drive.

Any advice appreciated

Are you sure the limit is a EVA limit and not a MBR limit on the the Windows box?  I believe I have seen LUNs larger then 2TB on the EVAs before

Definitely a EVA limit.  If you enter a value larger than 2GB, you get the error:

"Vdisk size must be an integer between 1 and 2047."

This also occurs on a HP EVA 4400 with the latest firmware.

You're correct, I was thinking of the 6400 which increased from 2TB to 32TB.  

Couple of options.  If you have multiple shares Youl could move them to the new LUN or perhaps use DFS to present a single space.  If none of these fits the bill then you have no choice but to span

Thanks.  Unfortunately it's only one share so it looks like spanning is our only option.

Cheers
