http://www.mail-archive.com/veritas-vx@mailman.eng.auburn.edu/msg00289.html

節錄
DSS/HPC
==========================
VxFS mount options:
Log mode= delaylog (best performance and enables data integrity)
Logsize= medium (doesn't need to be very much larger than default or
keep default)
Mincache=direct (turn off in-kernel buffering)
Convosync=direct (delay inode updates for writes to files)

Tunefs:
Read_ahead=1 (traditional vxfs read ahead enabled)
Fcl_winterval=6000 (50 minute update interval for FCL)

VxVM kernel tuning (/etc/system)
Set vxio:vol_maxio=32768 (max IO size = 16MB)
