DL580 G5 Internal Drive Perfomance

DL580 G5 Internal Drive Perfomance

We have two possible scenarios for our DL580 G5 and we would like to know which would give us the best performance/throughput.

Scenario A) consists of the DL580 G5 with a P800 Smart Array Controller and 7 x 300GB 10K Disks (Raid 5)

Scenario B) consists of the DL580 G5 with a P800 Smart Array Controller, an extra drive bay, and 14 x 146GB 15K Diksks (Raid 5)

Also, if we go with Scenario B, do we need two P800 Smart Array Controllers or is one enough for 14 drives?

Thank you.

The P800 has 8 internal ports only so for scenario B) you need a second raid controller. Or you can use a SAS expander card but you would perfromance would be lower.

With a second controller, you would not be able to combine all 14 disks in one array.

The P800 has external connectors too and you would not be utilizing them so you should be considering alternaltives with internal connetors only such as the (cheaper?) P200 or the faster P410.

Is there a 300GB 15k sas sff drive for the DL580G5 or possibly a 500GB 15k drive?

hello,

Raid 10 is faster than raid 5 but you will waste half of the space.

regarding option B, with an SAS expander board you do not need another controller and you can have a raid with 16 drives, if you need more details about it..like performance...check

regarding supported drivers, check the official HP doc.

Is the P410 supported/works for the DL580 G5? I see it documented as supported for G6 but not G5

The P410 is supported. Scroll down to "HP Storage Controllers"

That's the G5, there is no DL580 G6. Rumor has it that there will not be a G6 and G7 will be released soon.

theres a dl585 g6..... the last 5 stands for AMD processor ....

regarding p410... that will help you with the performance, a p410 + SAS expander Board + raid 5+0........ nice!
