Netbackup and MSDP questions

[Steve_Lussiaud]

Hello,

We use Dedup via MSDP in this environnment :

- 1 master Server - Linux RHEL 6.2 X64 - 24 Go RAM

- 2 media Server - Linux RHEL 6.2 X64 - 24 Go RAM with MSDP connected in 10 Gb NIC on switch 10 Gb Brocade.

For the Storage, we use Infortrend Bay with 24 To in RAID 5 connected in ISCSI on each media server

Netbackup 7.5.0.3 is installed

What do you think about ISCSI connection for deduplication storage area  in terms of speed, latency, availability ?

I use open-iscsi.

Have you tuned iscsi daemon and /or Linux kernel to improve backup / restore ?

HAve you tuned PureDisk to use with 10 Gb NIC ?

Each media server use 40 concurrent jobs

Does this number seem to hight ?

Thanks for your help

Regards.

Steve

Refer performance and tuning guide and alro Additional info on DeDupe which would give you tested outcome.

Seeing at your infra config.. It's still more than better what you are getting.. Further you can tune it and performing testing to see if it's returning with desired output or it's getting worse
