Recommended LUN design

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

Hi

I would go for storage vendor documentation, I pretty sure that they have guidance how to set up their storage to get as much as you can togoether with vSphere. For example, For XIV storage IBM recommended LUN with 2TB size but for DS8000 series recommended LUN size is 500GB.

Personally I prefer to have less number of big LUNs (less administration overhead and yo can assign to server more space then for exmaple in smaller LUNs)
