Other Notes

Failover is supported by an additional blade that operates in
standby mode. In the event of any blade failure, this unit takes over the
function of the failed unit. The standby blade does not contribute to
the performance of the system and is not included in the processor, memory,
or other components listed above.
Server blade tuning:
param ufs inoBlkHashSize=170669 (inode block hash size)
param ufs inoHashTableSize=1218761 (inode hash table size)
param ufs updateAccTime=0 (disable access-time updates)
param nfs withoutCollector=1 (enable NFS-to-CPU thread affinity)
param file prefetch=0 (disable DART read prefetch)
param mkfsArgs dirType=DIR_COMPAT (Compatibility mode directory style)
param kernel maxStrToBeProc=16 (no. of network streams to process at once)
param kernel outerLoop=8 (8 consecutive iterations of network packets processing)
param kernel buffersWatermarkPercentage=5 (flushing buffer cache threshold)
file initialize nodes=1000000 dnlc=1656000 (no. of inodes, no. of directory name lookup cache entries)
nfs start openfiles=980462 nfsd=4 (no. of open files and 4 NFS daemons)
param ufs nFlushCyl=32 (no. of UxFS cylinder group blocks flush threads)
param ufs nFlushDir=32 (no. of UxFS directory and indirect blocks flush threads)
param ufs nFlushIno=32 (no. of UxFS inode blocks flush threads)
Storage array notes:
The DMX3000 used for storage exposes LUNs across multiple Fibre ports.
Each file system is built on a stripe that spans 14386MB RAID-1 LUN.
There are two disk controllers per blade, one port each. Each port is
connected to one of the fibre channel switches so that each blade has one link
per switch. Each link on each switch is zoned to four Symmetrix fibre channel
directors (HBA) with one HBA to one HBA zone.
The DMX3000 was configured with 128GB memory. The memory is backed up with
sufficient battery power to safely destage all cached data onto the disk in
the event of a power failure.
