Updated: 02 Mar 2009
I've a big problem with my I/O performance to the SAN disk staging
This ist the "iostat" from my Solaris server
extended device statistics
r/s w/s Mr/s Mw/s wait actv wsvc_t asvc_t %w %b device
69.4 163.6 3.9 6.1 0.0 3104.9 0.0 13324.7 0 38 d60
r/s w/s Mr/s Mw/s wait actv wsvc_t asvc_t %w %b device
69.4 163.6 3.9 6.1 0.0 3104.9 0.0 13324.7 0 38 d60
I konw this is a very bad troughput on the media server.
My config
The D60 Device is a stripe over two 500GB SAN LUN's
- Solaris stripe size 512k
/etc/system
set ssd:ssd_max_throttle=20
set maxphys=1048576
set maxphys=1048576
The EMC Clariion LUN's are in RAID3 RaidGroups
- EMC setup = default
Netbackup Setup
NUMBER_DATA_BUFFERS_DISK
16
SIZE_DATA_BUFFERS_DISK
1048576
16
SIZE_DATA_BUFFERS_DISK
1048576
What's wrong in my config ?
