hit long before you notice you have internal issues within the TSM server.

Yep, doing a 200 GB database with high-end and reduntant SLC NAND is definedly
not cheap (let alone the 2 TB Bill Colwell described in his post). Not that
bunch of 15K disks and the power to run them is free, either. Cost per IOPS for
disk is actually terrible.

Hi Henrik,
Well as I was specing a new TSM server i thought, why not try for the best
performance possible and although the SSD drives drives the server costs up by
50% it wasn't out of the ballpark, therefore I wanted to hear from the
community what their ideas were.
As it stands I have a 100
Or maybe he has a huge amount of DB entries? If his options are either six SAS
15K or eight SSDs (50GB each), it means his DB is propably in the multi-hundred
gigabyte range. If he just needs the IOPS for smaller DB, then he would not
need 8 SSDs to beat 6 platters, even one or two could be eno
SSD to me seems overkill if you already have 24 GB of RAM, unless you need
superfast performance and are going to run a very busy TSM server with a huge
amount of concurrent sessions.

Hi Louw,
For a single instance 24GB of RAM should be enough.
For the OS is using SSD a bit nonsence, even SATA is enough, so don't
spend to much on that.
But if you want speed, look at the SSD cards of Fusion-IO
(fusionio.com) these cards are build for enterprise usage and have
redundancy on the
