Hi all,
I'm piecing together the info I need from this list's archives. Thanks much
to all the members and the host!
What I'm preparing to do is determine the optimal configuration for my
environment. I want to maximize throughput, so I'm thinking multiplexing,
where a machine with multiple drives/mount points will kick off a relative
number of jobs, and where my two drives will handle multiple streams. Here
goes:
Environment Info:
*NBU 3.41_2 on Win2K Advanced Server
*100 Mbs shared LAN
*StorageTek L40 w/dual Seagate Ultra-SCSI LTO drives
*145 Clients (Windows & Solaris)
*100% Development Environment
*Differential Incrementals: M T W Th F, 2 week retention
*Fulls: Sa-Su, 2 week retention
NBU Settings I'm concerned with:
Classes:
Solaris:
Cross Mount Points: Unchecked
Allow multiple data streams: checked
Limit jobs per class: unchecked
Files: ALL_LOCAL_DRIVES
Windows:
Cross Mount Points: Unchecked
Allow multiple data streams: checked
Limit jobs per class: unchecked
Files: ALL_LOCAL_DRIVES
Storage Unit Management:
Maximum concurrent drives used for backup: 2
Maximum fragment size: 0
Maximum multiplexing per drive: 3
Configure NetBackup:
Server:
Maximum jobs per client: 2
Maximum data streams: ?
Individual Clients:
OTM Enable OTM during backups: checked
OTM Initial cache size: 100
OTM Maximum cache size: 0
OTM Busy file wait: 5
OTM Error Control: Retry OTM
OTM Snapshot: Individual drive snapshots
With my goals in mind, are these the correct settings? How does "Maximum
data streams" fit into the equation? Am I missing anything (no snide
comments!).
Thanks again,
Chris
