Tape Library Configurations - Best Practices
Hello,
I've configured the below in my environement lately:
- 4 Media Servers (A,B,C,D) with A being master as well. Each media server has its own PureDisk storage and connected to 3 TLs as below.
- 3 Tape Libraries (X, Y, Z with 4,2,1 drives respectively, a total of 7 drives)
For tape library configurations, I've performed the below:
a) Single "Storage Unit Group" with each 12 STUs, each representing the 4 Media servers connected to the 3 TLs.
b) 5 Different "volume pools" for different applications like Oracle, SharePoint, Exchange, etc.
c) About 9 SLPs, configured to reflect the various PureDisk connected to the various TLs.
d) All 3 TLs are managed by single robot control host, the master/media server "A".
My questions are as follows:
1) Would there be a better way to configure the above?
2) Currently I see that one of the media server "C" connected to 2 TL, uses both but not all the drives. No other tape jobs with other media servers are on. But tape jobs in "C" are queued rather than using the available 2 drives. Am i missing some configuration which limits number of drives?
3) How can i make sure all my drives are running at best possible performance level and are utilized simultaneously, apart from proper job scheduleing :)
