P4300 IOPS

Hi,

Can anyone tell me how much a P4300 node IOPS can handle?

Depends on the Drive Types (SAS/SATA, Spindle Speed, etc.), the internal RAID configuration, and the number of drives in use.

Hi there,

LEt's say a p4300 7.2 TB SAS network 10 raid 5 hardware level.

Per node, you are looking at a rough estimate of 8 x 100 (100-120 IOPS per spindle w/RAID5) so around 800-960 IOPS x 2 (as I assume you are looking at the P4300 starter SAN), so about 1,600-1,920 IOPS total for both nodes.

Hope that helps.

According to the HP P4000 Sizing Guide (available to partners only), the IOPS spec for what you reference would be 1700 IOPS per node (network raid 10 and hardware raid 5).

djlaube -

How would you get 1700 per node? That would be roughly 210 per spindle (8 spindles in the P4300), which is way above anything I have ever seen.

I think perhaps since HP quotes the Starter SAN as 16 disks (when it is actually 2 nodes), maybe they quote the two as a bundle.
