We have a PV TL4000 with 4 half height drives. I hope expert here give me guide on how many logical libraries I should configure the TL4k.
Hardware and software setup:
TL4000 w 4 physical drives;
each drive connects to a PE R910 server via SAS HBA and no second backup server (not planned);
44 slots are populated with LTO5 tapes;
Backup server runs Backup Exec 15;
A number of media sets for different backup jobs (Win, Linux, and VM);
Goal: All four drives should be used to backup to tapes simultaneously. Any drive should be able to access any tapes so more than one backup jobs can use tapes in the same magazine.
Based on above goal, how many logical library I should create? One or four? If it's one, are there any drawbacks and limitations for having one logical library? If it's four, benefits/drawbacks/limitations.
I read through the manual 'Chapter 3' but still not quite clear. If you could offer some tips, it'll be greatly appreciated.
Thanks,
Yu
