Other Notes

We set NFS share access through insecure port larger than 1024.
RAID controller's disk cache size is 512MB (Disk cache can be extended to 1 GB).
NVRAM: Each RAID controller has 512 MB of write-back cache (72 hours battery-backed).
Each NAS server and RAID was connected with 2 ports through 2 Gbps FC link.
Netbine500 has two RAID controllers, which were configured active-standby failover.
The RAID is configured with 2 LUNs. Each LUN has 6 disks with RAID level 5 and the stripe size is 128 KB.
Each NAS server has onboard Adaptec U320 SCSI controller for OS disks.
Two OS disks in a NAS server are mirrored with software RAID 1 for failure protection.
Uniform Access Rules:
Each node has 1 network port(N1) for NFS service connected with the LGs.
Each node has 1 network port(N2) for cluster operation connected with each node in the cluster.
There are two LUNs in the RAID. A file system consists of one LUN.
Each LG has 20 processes and the 10 processes access F1 via active server and the other 10 processes access F2.
Stable Storage:
There is an integral UPS for each NAS server, which guarantees sufficient power in the event of power failure.
The irrecoverable power failure detected by UPS, the active NAS server flushes all data safely and shutdown to failover.
Buffer cache mirroring are performed between active node and standby node to prevent data loss in buffer cache.
If active node fails in H/W, OS or some media, the standby node takes over all services and data without any loss.
When the cluster is recovered, all written data in buffer cache are flushed and cache mirroring is started.
