Hi there! our tsm server got out of disk space and I want to reinstall the complete system, but I don't know the best configuration of the raid system. raid1, raid1E, raid5 ? where to put the database volumes logfile, system, disk storage group volumes... a lot of questions... is it really nescesarry to use copy database volumes should tsm do the mirroring of the data base volumes or hardware raid? perfomance - security?
now a short description of my system: TSM Server 4.2.2.5 Windows 2000 SP3 IBM Netfinity 5500 Dual PIII 550Mhz 512MB RAM IBM ServeRaid II 4MM Tape IBM 3583-72 incl. 2 drives Harddisks now in the system: 3 x 9GB SCSI (non raid) 1 x 80GB IDE 1st SCSI disk = system (w2k, tsm) 2nd = db volumes, dblog 3rd = db copy volumes, dblog copy ide = disk storage group Harddisks available for future: 3 x 9GB SCSI 5 x 36GB SCSI (all SCSI disk hot-plugable, but there is only space for 6 disks in the system) 1 x 80GB IDE i thought 3x9gb + 3x36gb raid5 is ok, but I am not sure, because of the db copy volumes... or 2x9gb + 4x36gb raid1... does anyone has any suggestions for my problem? thanks thomas ps: what do you think about upgrading to TSM 5.1
