I'm thinking of going for RAID for my MCITP studies, I'm having doubt for choosing what kind of RAID.
RAID0 ,1 or 5 ?... IMO, I dont want to get RAID 0 as there is a high possibility of failure.
And what i want to know is.. for virtual machines.. which is more important.. read or write...
if read is impt... i could get a RAID 1, quite slow for writing but double read rate..
fyi.. i dont have enough budget to get SSD
Raid 1 will not give double read speeds. (1 drive will be hidden at all times and is a real time duplicate of the first drive)
performance will be a little slower than 1 single drive but provide redundancy.
I have just setup a Hyper-V envioroemnt here at work on an iSCSI attached SAN.
i picked RAID 6 (same as raid 5 but with 2 parity drives instead of 1)
its provided quite nice performance while still giving me the redundancy we need.
how many drives are you looking at using?
we currently have 8 drives (450gb SAS 15kRPM) with expandability to 12
