Re: [ADSM-L] Server stgpool volumes and GPT

Hi,

What evidence do you have that MBR volumes have better performance than
GPT volumes on Windows?

Actually, you may get better performance out of Windows if you leave off
the GPT.  You don't want really large storage pool volumes anyway, so
partitioning it out with 2 TB File systems, would be a good idea.  That
would remove another level of complexity, and overhead on the server
itself.  The fewer things you have between the App (TSM) and the
hardware the better.

Or, better yet, use Linux and you'll get more out of your hardware.

See Ya'
