I was wondering if there is anyone with an as close as possible similar setup as mine.
We bought a NetAPP FAS 2552 with SAS and SATA drives, it was supposed to replace our aging EMC CX3-20. We do have an Dell MD 3620i as well in our datacenter.
I cannot wrap my head around these performance issues I see, NetAPP is consistently slower in backups compare with MD and even way slower compare with the EMC. It looks to me like our upgrade is actually a real big downgrade. What kind of speeds do you get with such setup?
My setup details: iSCSI 10 G with jumbo frames, Round Robin, software iSCSI initiators on ESXi 5.5, veeam B&R 8 running on hotadd and/or storage snapshots against NetAPP.
Full backup jobs run at ~100MB on NetAPP and at 2-3 times that speed against MD. I compare this for both of them at SAS 10 k rpm. NetAPP 36 disks in 2 x raid dp agregate , MD in 24 disks on raid 10. For both bottleneck is always the source, followed far by proxy. Network and destination is pretty much 0%.
Please, if anyone has a NetAPP in their care, can you please share here what kind of speeds do you have in your environment? I wonder if my expectations of it are not too high or maybe some other issues are in my environment.

don't use more the 50% of the system capacity, disable dedup,....
