Hi Somen,
- You can snoop your gig-e interface. Can use 'snoop -d ce' - again, substitute
your gig-e driver for 'ce' as appropriate.
- Are you backing up enough clients in parallel to utilize the gig-e interface?
- The old Sun gig-e adapters (ge driver) had pathetic performance. The newer
h/w and drivers (ce driver) are much better.
- Why are you still using/configuring your 100 Mb interface?
- Is your gig-e and network switch running at gig-e speeds? Can check using
'ndd /dev/ce link_speed' - substitute your gig-e driver for 'ce' as
appropriate.
- Are your drives so busy that they can't accept data more quickly? Can check
with 'iostat -xnp 3 | grep rmt' and look at the '% busy' column.
- Are you runing enough drives in parallel?
Regards,
/\/elson

We had 100MB interfaces on our clients and server and now we have 1 GB
interface on the server.
To send data on the nsr server I have configured the client in its setup I
have specified to use the GB interface on Server Network interface option.
I have stopped and restarted the networker client. I am not seeing much
performance increase while writing to the tape.
Can anyone tell me how I can check if the nsr server is getting all the
data through the desired interface? My server is running Solaris 8
Is there any parameter or setting in networker to increase the network
buffer size and number of network buffers to accomodate more data ?
Thanks in advance!
Somen
