Hi
We currently work on implementing our new DataDomain in the networker environment. The networker Server is a T5120 running Solaris 10, with SAN attached storage (EMC VMax) and a DataDomain DD670 connected to 1GB Lan device. On top of it we run Networker 7.6.2 with Boost Option enabled.
To explain the problem I should start with a Configuration like this:
10 SAN Filesystems total capacity 1.7TB
1 DD-Boost Device (10 Sessions)
1 SaveGrp
1 Pool
Result --> Average throughput 38MBytes/sec running für 12.5hours (after 3 runs)
Then we tried to add a 2. DD-Device
10 SAN Filesystems total capacity 1.7TB
2 DD-Boost Device (10 Sessions/each)
1 SaveGrp
1 Pool
Result --> Average throughput 36MBytes/sec per Device running für 6.5hours (after 3 runs)
More devices
10 SAN Filesystems total capacity 1.7TB
4 DD-Boost Device (6 Sessions/each)
1 SaveGrp
1 Pool
Result --> Average throughput 28MBytes/sec per Device running für 4.25hours (after 3 runs)
and more devices
10 SAN Filesystems total capacity 1.7TB
8 DD-Boost Device (4 Sessions/each)
1 SaveGrp
1 Pool
Result --> Average throughput 19MBytes/sec per Device running für 3.1hours (after 3 runs)
You see, the throughput raised from 36 to 152MByte/sec when defining more devices, but to save one single filesystem with 500GB will still take too much time when we can't break this 36Mbyte/sec for a single device.
Is anyone here experiences similar problems/behavior? Are there any parameters to be checked?
Any ideas are welcome
Regards
Beat
