|LG #||LG Type||Network||Target File Systems||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.
