Re: New Server Setup...Drive configurations



>From what I've read, I'd say:

1) a single R10 is a *bad* idea. You should not have the log files and the
databases on the same drive. It will have a significant performance impact.
2) The log files should be on an R1 and the data should be on R10 (R5 is OK,
but has a write speed penalty)
3) not sure what a LUN is...
4) The 2x36 array should be RAID-1

Also, it is recommended (once again, for performance) that each RAID array
be on it's own channel. This would require one or more RAID adapters. If
there are only two arrays, then you could get an adapter with two internal
channels.

I don't know where the tempdb file(s) should be..

Having said all this, you should really first analyze your database size,
complexity, number of users, transactions, etc. before you make a final
decision on the configuration. Without doing that, you are likely to over
build the machine and spend more than is necessary...... Multiple RAID
channels can be costly and a RAID-10 array will require at least 4 drives
while the same size for RAID-5 will require 3 drives...... However, be sure
to allow for future growth, since changing it later will be more costly and
take a lot of effort....
