we have 4gb/s fiber channel, Emc cx3-20 san and backing up from raid 1+0 8 disk array. all backups from this array and anyothers in our san only backup at 5mb/s using either full VM or FIle level VCB backups.
When i ran a disk benchmark i get 150mb/s on that raid.
How can i make backups faster? how do i even start to isolate this issue? what kind of preformance from a 1+0 should i recieve(15000rpm fc)? also on our sata raid (7200rmp 1TB drives) on the san its a 10disk raid 5 and we only get 25mb/s this seems drastically lower then it should be.
I welcome any help on this matter

i wanted to add that over the network backups are around 130-150mb/s. why would fiber channel backups be so MUCh slower. also the network backups are not using vcb.
Don
On the VCB Server do you have powerpath installed?
How many HBA do you have?
Andre
powerpath yes, 2 qloqic hba's.
Try to disable multipath on VCB system.
A simple way is remove PowerPath license, and PowerPath will work only in failover mode.
Then reboot your VCB and try again.

I will try this out this week and reply with the results soon as i can.
