Exchange 2010 HA Question

Question,
How many out there uses the HA configuration having both DB+LOG’s on 1 LUN, I ask because I have 3 Server and 18 DB total putting 6 DB per server. Now if I split the DB and the T-Log on to 2 different LUN’s on my SAN I will run out of drive letters really fast  and will not be able to do DAG so I’m thinking of just putting both DB and T-Logs on the same LUN and adjusting the LUN size for the T-LOGS. Now I know the biggest thing is IOPS I will be running 96 x 1TB 7200 Drives at RAID 10 giving me about 4800 IOPS but will I see any performance issues running the LOGS and DB on the same LUN @ RAID 10

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing.

disk letter -> you don't use drive letter to assign LUN.

you use mount point (instead of assigning drive letter, you can mount into empty NTFS folder)

so theoritically, you should have a M drive, and put all your DB and LUN into those folder like

M:\Data1\DB
M:\Data1\LOG

(or something similiar)
