Verifying data path on a backup
I have a Clariion with several servers (File, SQL, Backup server, etc.) attached. I backup to disk on a DAE then stage to tape with Networker 7.4 SP1.
I'm only getting about 50mb/s writing to disk. How can I verify that the data is flowing over the Fiber and not going out over ethernet and coming back to the backup server instead?
It seems like 2GBps fiber should be faster.
If this belongs in the Clariion forum I apologize.

You sure that Backup Server resolves fine by ip belongs HBA for the client.
Execute from Backup Server:
#ping cut_name_client
#ping long_name_client
#ping ip_address_HBA
#nslookup cut_name_client
#nslookup long_name_client
#nslookup ip_address_HBA

Sorry, when I wroten about HBA I was thinking in Ethernet.
Forget the previous lines where I told you cut, long and ip HBA.
Really, the proof is you disable ethernet card and launch backup, in this way, you will see if it is ok and his speed.
Sorry for the confussion

Now I have time for answer.
Forgetting the confussion (I do not in what I was thinking, I am with 100 things
Your Backup Server has ethernet 1GB and HBA, which, is connected in SAN.
Clarioon and Library are connected to SAN, too. Is it ok?
If yes, when the backup from disk to tape starts, it is going to backup on device, which, you have selected in NetWorker. If this device is seen by the HBA (is in SAN), the backup is by Fiber.
Other example is if you have Stand Alone attached directly to Backup Server, only is seen by Backup Server by port SCSI. If you configure this Stand Alone, and some pool has added this device Stand Alone, and a group, (which, has differents clients with ethernet), starts, then the backup by this pool is done by Ethernet, because device Stand Alone is out SAN.
Sorry so confussion, I wish help you.
Regards.
