Other Notes

OS Tuning:
Checkpoint disabled on all volumes: disabled via menu
NFS worker threads set to 120: set nfs.nworker 120
Disable system monitor: set sysmon.test.enable yes
Disable directory audit: =sfs2_no_dir_audit=1
Disable file system read ahead: =sfs2_nrax=0
Disable file system access time update: fsctl atime disable *
Maximum queued HBA commands limited to 128: set qlogic.isp.maxthrottle 128
The storage subsystem consists of (4) dual-controller Sun StorageTek
NAS 5320 RAID EU controller trays with cache mirroring disabled,
and (20) Sun StorageTek NAS 5320 RAID EU F expansion trays, totalling
352 drives. (88) 3+1 RAID 5 LUNs are configured.
All LUNs are available to both NAS heads
via the SAN switches, with each head having primary server
responsibility for (44) LUNs. (2) Brocade Silkworm 4100 and 3900
switches instantiate the fabric. In the case that a NAS head fails,
the remaining head automatically assumes responsibility for LUNs
belonging to the failed head.
There are (88) LUNs.Node 1: F1 is on first port of first controller,F2 is on first port of second controller,
F3 is on second port of first controller, F4 is on second port of second controller, and etc.
Node 2: F45 is on first port of first controller,F46 is on first port of second controller,
F47 is on second port of first controller, F48 is on second port of second controller, and etc.
Each 252GB file system is built from a
single segment, with each segment residing on one RAID5 LUN, (1) file
system per LUN.
the Ethernet switches are interconnected thought single Gigabit port.
There are eleven clients and a cluster node on each one.
One port goes to each of the FC switches from each dual HBA.
Controller arrays provide battery-backed cache memory. In the
case that line power is lost, battery power is sufficient to
preserve cache contents for 72 hours minimum. If the batteries
are depleted to the extent that they cannot maintain memory for
72 hours, the controller will automatically switch to write-
through mode.
The tested system is a failover cluster composed of (2) nodes.
There are (2) gigabit ports per node. (1) port is used for
heartbeat and administration. The other port is used for file
system serving. Each node is the owner of (44) file systems and
has the capability of taking over the partner node file system
The network under test utilized GigaBit ethernet with standard frame size.
