How fast of your msa2012i ?

does anyone can sharing your msa2012i performance information?

I have msa2012i Dual Controller,
14pcs 450GB 15k SAS @ RAID5/MPIO/Jumboframe 9K/Server2003/Dynamic Disk

Around 125Mbps read/write speed.

Re: How fast of your msa2012i ?

Interesting results!
We have a major issue with our MSA 2012i
12 SAS 300GB 15K drives in Raid 5 configuration.
Copying a 5GB file we are getting 48MB/s
Same file on a Raid 1 with 2 SAS 300GB 15K drives is 70MB/s.
Which HBA and switch are you using?
Also what are your results when accessing the Raid 5 over the network using a Windows Share? Our is 15-20MB/s (Slow)
We have an isolated LAN for iSCSI and no activity on our production LAN.

Re: How fast of your msa2012i ?

last post i have some mistakes,
We are gettings 125MBytes/s file copy for 12pcs of 450GB running in RAID5

If you have time, download the Hdtune and try to benchmarks your iSCSI storage.

For HBA, we are using *ell Server with on-board broadcom 5708 TOE NIC with Microsoft iSCSI Initiator and the cable is directly connected between the server and storage without any switch.

For slow file copy on windows sharing, i guess it is windows file sharing problem, even for Server Local Disk to Server Local Disk, you can just getting around 20 - 30% of 1Gbps speed. You can try to do multi-file copy through network in the same, you could saw the total network usage is increased.

For jumboframe, i can't saw any improvement for the file transfer speed, for cpu usage just a few % differnence, so i have configure it backed to 1500 MTU.

I will try a direct access at some point this week. As far as the jumbo frames I do agree no differance. Between the storage server and the MSA we are getting anywhere between 48MB/s for raid 5 and 70MB/s for raid 1.
