Ok, I figured it out. Since we use Qlogic branded adapters and QLA driver instead of the QLC driver there was a setting we needed to change in /kernel/drv/qla2300.conf. It is the equipment of the pci-max-read-request variable in qlc.conf.
# PCI-X Maximum Memory Read Byte Count. # Range: 0, 128, 256, 512, 1024, 2048 or 4096 bytes # Default: 0 = system default hba0-pci-x-max-memory-read-byte-count=2048; Anyway, that plus setting maxphys=0x800000 in /etc/system seems to have removed all bottlenecks from the T2000 and we are able to get linespeed data transfer speeds through the QLE2462. We are now able to vault jobs at around 160MB/sec from VTL to LTO3. I've only tried two concurrent vaults for x2 performance. +---------------------------------------------------------------------- |This was sent by [EMAIL PROTECTED] via Backup Central. |Forward SPAM to [EMAIL PROTECTED] +---------------------------------------------------------------------- _______________________________________________ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
