What measurement tools do you use to determine this throughput number?

        We have one that uses three (3).
        Two fast ethernet & one GB.
        You have to remember that your standard TCP/IP routing is what
determines
        how these boxes talk !
        Client traffic will go in which ever interface you point to and will
return
        out to the client based on standard routing in the system (but will
go back
        to the ip in the received packets).

        Back when we built our environments "SAN" wasn't really around so we
built a
        sudo-SAN.  Works great !

        Our busiest S70 TSM server (just 2 processors & 1 GB memory) seems
to max
        out at about 60-ish GB/hr of inbound  compressed client data
(actually kind
        of hard to find enough clients to push more than that ;-) but I need
to
        check recent #'s )
                (so during DB backups, that is about 240 GB/hr of client
file spaces
        being  backed up)

        Is this good or bad ? ? ?
        It is just what we see and it serves our needs !

        Hello,

        Does anybody know if a single TSM server can listen on different
ip-adresses
        (on different nic's)  ? Or do you need to run multiple instances on
one
        machine ?

        TSM Server Config example :

          Listening for backup data on NIC1 : 192.168.10.10:1500
          and                               on NIC2 : 10.10.10.10:1500
          + other nic for normal lan traffic


        Just wondering if adding extra LAN cards in every client to increase
the
        total bandwith, is a
        cheap alternative for SAN environments.

        For example : client config with 3 NIC's :
                                        NIC1 : regular client traffic
                                        NIC2 : for online database backup
(scheduler
        1)  (backup lan 1)
                                        NIC3 : for backup of regular file
(scheduler
        2)  (backup lan 2)

                                        2 x 100 Mbit bandwith to backup

        Any remarks about this ?  I agree, it isn't a good alternative, but
I was
        just wondering if this is possible ?

        Thanks !
