Are these LAN clients or SAN Media Servers or what?
I can get close to 30MB/s from HP DL360/380 G3s from local disks via the
onboard GigE card. IF I'm only running a single job....

        I'm curious to hear what kind of speeds (mbs/sec) others are
getting backing up windows servers. 
        
        Running Netbackup Enterprise 5.1 mp6 under Solaris10 on
master/media servers. 
        
                a.        Using brocade 2g ports 48000 director. 
                b.        IBM Ultrium LTO Gen2 drives 
                c.        Sun branded Qlogic 2gb cards. single port
feeding each tape drive. 
                d.        The storage on the windows servers is FC
attached Hitachi Tagmastore 9990.  (Very fast drive configuration.) 
                e.         Servers are HP G5's also 64 bit. Some are 32
bit. Seems 32 bit servers are actually faster. 
        
        note:         Some of my other backups such as Solaris, Linix
and Netware can get as much as 20 mb/sec with this configuration. 
                So why are the windows servers so slow? Any  one have
some kind of idea what may be a cause?  Or it is what it is!  Windows!
