Please advise the best way of backing up NAS vol

[trick-on-tsm]

Please advise the best approach and tuning to quickly backup the entire 500 TB NAS data

since 2 weeks TSM was able to backup only 135 TB
which we are not happy with this

Environment:
We are using 10TSM instances on Linux RHEL 5 on IBM p570 box 128Gb Memory,
16 CPU's and 10 Gig NIC and we have 3 bonding interfaces using mode4 (link aggregation) to get 20 Gigabit aggregate. 42TB of DS4800 storage is using for TSM DB & stgpools.

around 60 NAS volumes mounted on TSM server to backup
we are using 4 TSM instances to backup 500 TB NAS volumes and each instance has its own Storage pool 3 TB each,.
library 3584 with 22 L4 3592 drives

following are the configuration of server option files

Which NAS Device are you using - IBM - EMC - NetApps.....
Each have Native tools or addon packages which will backup to TSM accordingly.

 

[trick-on-tsm]

TSM IBM DS4800
For DB lun we are using Raid 10
for Stgpool we are using Raid 5

NAS Devices are combination of the following
IBM , NetApps, EMC

 

[trick-on-tsm]

we found that the responce from NAS filer is slow
we still investigating more
