[Veritas-bu] Re: Tuning Solaris 10 for NetBackup Media Server
Honestly, you shouldn't have to do much.
As long as the media server is gigE and your tape drives are working properly
(FC ones are pretty easy) I would just make sure you got the buffers set
something higher than the default:
Solaris 10 defaults to 25% of system memory for shared memory. As long as you
have more than a couple GB I recommend you use 64 and 262144 respectively.
Your mpx settings also calculate into how much max shared mem will get used by
We've had great success with our T2000 servers that use FC LTO3. In our
environment, some higher end linux/solaris clients over the network can write
70-80MB/sec cumulatively via a couple jobs multiplexed to a single LTO3 drive.
We have the 8 core 8GB T2000 systems and they don't even break a sweat (load
<.5 0% iowait, etc). We usually load em up with lots of other tasks.
Windows clients just don't backup very fast over the network, even tuned.
You'll have to mpx several of those clients to a single drive just to meet the
native write speed.
