We are moving to a new SAN, and was hoping for some advice on how we should structure the sizing of the LUN's.
Everything on the new SAN will be in a large RAID 10 pool.
We have a mixture of Windows 2003 and 2008 guests, doing everything from domain controllers, file and print, web services, Exchange and SQL.
I was wondering if there was a rule of thumb for how many guests should share a LUN?
How big should LUN's be?
Lots of smaller LUN's, or a few large ones?
Any advice would be appreciated.
Thanks in advance
