I'm working on setting up our DSSUs for our new Netbackup system, and I've got an idea I want to float here. I've got 86% of our data on a guaranteed gigabit backbone that can all push somewhere in the neighborhood of 50MB/sec+ to media servers with trunked 4xGbit Ethernet. I've also got a hundred or so, slower clients with 100F front ends that push somewhere closer to 5-8MB/sec. I'd like to segregate these backups and where they write two and I've come up with the following ideas. DSSU1 - Slow Front End DSSU on each media server that can accept 10 simultaneous streams from the slow 100-F front end clients to a 2xGbit trunked media server front end port. DSSU2 - High-Speed DSSU on each media server that accepts 8 simultaneous streams from Gigbit clients to 4xGbit trunked media server front end ports. Make sure server's w/ 100-F Front ends use the DSSU1 Storage Group and servers w/ Gigabit backend connections use the DSSU2 storage group. I really can't think of any other way to have a high number of streams for the slow servers but a low number for the faster servers. Also - anyone using Windows for DSSU storage? Any comments on NTFS fragment size, compression, RAID5 vs. RAID6 also multiple drives (DSSU1 = F:, DSSU = G:) versus single drive letter (DSSU1 = F:\DSSU1, DSSU2 = F:\DSSU2) ?! I've got two weeks fo testing ahead of me, but I'd look forward to hearing any "pointers" -Jonathan
