SMART ARRAY 3200 WRITE PERFORMANCE

Hi, i'm having performance problems with my smart array 3200 controller.

i have 5 * 72gb disks.
2 logical drives: 1 Mirror, 1 raid 5 (3disks)

i achieve 2 Mb/Sec write performance????
for read, that is 38 Mb/Sec....

Any idea what's happening?

Thx !

Re: SMART ARRAY 3200 WRITE PERFORMANCE

Hi;

You are probably using a small blocksize for your writes. Try increasing your blocksize, up to 64k. That should help dramatically.

Good luck,

Re: SMART ARRAY 3200 WRITE PERFORMANCE

Hi Thank you for your advice.

i'm just wondering, if i chanhge that while having data on the logical drive,
will the drive remain available?
it there any risk for data loss?

Thank you!

Re: SMART ARRAY 3200 WRITE PERFORMANCE

If you're running Windows and you want to change the blocksize on the filesystem, you will need to reformat the logical drive with the new blocksize. So, yes, you will have to backup/restore the data, as that's a destructive operation.

I was referring more to your benchmark test - if you can use a larger blocksize, it should go faster.

What are you benchmarking it with?
