Hello all, I fear that I am looking for the impossible. I am a network engineer trying to troubleshoot a transient throughput issue with a few of our Arcserve backup servers.
It seems like for a few weeks at a time everything will run well -- backups clocking 300-400 MB -- and then something happens and the speed drops to 50 MB without any warning.
The servers are IBM, the NICs are all forced to 100/Full and are fully capable of FUll duplex-- the Cisco 6509 Switch Gear is set to correspond 100/Full.
What I need to understand is something more about the network behavior of this application.
1.) How does arcserve communicate to the target server to initiate a backup?
2.) What network port, protocol, etc is used to communicate in a TCP/IP Windows NT/2000 environment?
3.) Does WINS play a role in the Arcserve agent resolving the IP address of the Arcserve server for returning requested data?
We use Arcserve 2000 and Brightstore. The various client agents are deployed to the target servers. Sadly I do not know full SP levels as the server gents handle that end.
We have a 32 Gbps backplane that is barely touched and microswitched 100/Full connections or gigabit connections all around -- so I have a hard time thinking the throughput is a network issue but want to be able to track down the root cause.
Thanks in advance for any help you can render.
