This is touted as the minimum requirement and it is. To allow tapes volumes to perform space reclamation etc. you need a minimum of 2 drives for simultaneous tape mounts.
Perhaps you can do fancy things with DASD devices, but this is not the aim with a tape library really when you want to physically move data to safe locations. DASD is entirely not suited for that purpose in the main. >From my experience, I'd recommend 4 drives, and 5 if you can get it as a spare in case one fails. This is for a large/active site. This allows you to get reclamations out of the way quickly etc. If you have a small site perhaps 2 will get you by and you can add more drives are required. We used to run a 3575 as our primary library with 2 drives and it used to spend the entire day performing reclamations and would get behind in this task which was bad as it wouldn't be sending tapes offsite or recall any and we'd run out of available scratch. This was a management decision not to add any more 3570 drives..... It's now superceded by our 3584 LTO and performs minimal backup tasks. When you need reclamations to occur but you also have to restore files, what do you do with no drives available? Just some ideas. > -----Original Message----- > From: Douglas Currell [SMTP:[EMAIL PROTECTED]] > Sent: Tuesday, July 16, 2002 6:56 AM > To: [EMAIL PROTECTED] > Subject: 2 drives are required for LTO? > > One of the System Admins has been talking to an IBM > Business partner and was told, apparently, that the > use of two drives is not only recommended but is also > required with LTO.
