Other Notes

There are 6 IBM TotalStorage FAStT700 Storage Server units attached to
the SUT. Each FAStT700 contains 2 controllers. Each controller is
connected to an FC adapter. Also, each controller has a 1GB cache.
Writes to either cache are mirrored in the other such that the total
effective write cache is 1GB per FAStT700. There are 5 EXP700 expansion
units connected to each FAStT700. Every EXP700 contains 14 physical
disks. A logical disk is composed of 5 physical disks in a RAID-5
configuration. There is one test filesystem per logical disk.
EXT3 is used for the OS. JFS is used for the test filesystems (F1-F84).
DCM is a Dual-Chip Module, one dual-core cpu chip plus one L3-cache chip.
SMT stands for Simultaneous Multi-Threading. SMT is a processor technology
that allows the simultaneous execution of multiple thread contexts within a
single processor core. SMT enabled is the default mode of operation.
There were 2 external 7311-D20 I/O drawers used in this configuration.
Each of the drawers contained 6 Fiber Channel adapters.
Used one of the integrated gigabit ports, plus all ports of the 3 dual port
gigabit adapters, which were placed in the internal slots.
Server specific tuning:
"noatime" and "nodatime" specified when mounting the JFS file systems.
sys.vm.min_free_kbytes = 40960, modprobe jfs commit_threads=32 nTxLock=65536
nTxBlock=65536, boot options: "selinux=0 elevator=noop numa=off iommu=vmerge"
The number of NFS threads is 64 (/usr/sbin/rpc.nfsd 64).
F1-F84 exported with no_wdelay(no write delay) option.
Client and Server tuning: Gigabit Ethernet MTU=9000
net.core.rmem_max = 1048576, maximum receive socket buffer size
net.core.wmem_max = 1048576, maximum send socket buffer size
