tRAID Performance expectations
« on: April 12, 2014, 02:11:15 pm »
Hi Folks

I am having a play with flexraid for the first time and before buying a license, want to know what the realistic expectations are for the final setup.

I am intending using quite a few drives in a set, with one or more (happy top be guided!) parity drives.

Now, using HDtune the drives on their own (ie discreet drives) report a fairly flat 170-180MB/sec each.

I have 6gbs JBOD controllers (LSI) and both HP and LSI expanders within shelves of drives, so as near optimal as I can justify in terms of cost!.

When I did a performance test in Flexraid before creating the raid, it reported around 33mbs - which was dire!

When it did built the party over a new 5 spindle set + single parity, it reported just under 700MB/sec.

What in reality should I expect from the final raid set?

Thanks in advance for your experience, help and advice.

David
