I am looking to understand what is the backup restore perf for fas9500. Approx how much throughput per hr and for what system specification.

Also, if there are any performance benchmark then please share!

Thanks,

what protocol are you using for backing up? CIFS? SnapDiff? NDMP? SnapMirror? SM2T? iSCSI? NFS?

Nfs.

Depends on many factors:

  1. How many volumes
  2. How many disks and what speed
  3. Block size (4k, 64k) and r/w ratio
  4. How many nodes
  5. How many files and directories
  6. How deep and wide those directories and files are
  7. ???
  8. profit

Honestly I'd get a sizing done by your account team through Fusion to get an idea.

#

Also, backups generally have more overhead. Assuming a straight copy using "cp" or something like XCP, you can expect a linear, predictable amount of performance because it's single or multithreaded.

#

Backups have more overhead because the initial copy may have to scan the backup, etc.

#

Also if you use a backup engine that uses snapshots, it will use Snapshot/SnapMirror tech which has a different performance profile.

#

So...the answer we can provide is...yes it will perform at some rate.

I understand. Thank you. That's why I was looking for any published benchmarks

#

For instance dell 9910 spec sheet claims a 75tb/hr max perf. In comparison where would fas9500 land without additional licenses? And maybe with snapmirror. Not looking at bluexp

How many maximum 60 drive dsc60 expansion shelves can fas9500 accommodate ? Does the racked appliance come as 42U?

each HA pair can handle 24 DS460C shelves, and you can have up to 12 HA pairs in a cluster (probably more with a PVR)
