Hello managers,
your first answers to my question have come in and it showed up,
that i forgot one point:
our 1000A sits alone at a 10baseT-port of a switch and the "mrtg"
does not show any remarkable traffic over that port. This is why we are
thinking, that the net is not the bottleneck...
My original question was:
to have a good server machine for the (near) future, we bought an
AlphaServer 1000A with DU-4.0B, 192 MB and 5 PCI-SCSI busses; we call it x00.
One of these busses is a wide SCSI, where we have around 150
user-home-directories, which are accessed ONLY via nfs
from several other AlphaServers, where those users have their local
diskspace.
When i now cp to another nfs-exported disk on another (narrow) SCSI-bus
(of x00) around 200 MB "locally" on an old ultrix-machine, where
this second disk is mounted (from a disk attached on that ultrix-machine)
i recieve several times the message pair
NFS3 server x00 not responding still trying
NFS3 server x00 ok
until the transfer finished.
I don't understand this. i thought, that such a slow transfer should not
be able to need more than the 1000A can handle. (In the near future we want
the x00 to handle far more disks!) We have 16 nfs-daemons running...
What can i do to make the situation better???
Thank you!
