User's guide for the Sonnet Fusion RX1600RAID 16-drive Serial ATA disk array rackmount storage system. These directions apply to storage systems with drives.
With a RAID 5 or 6 group: set Speed Read to Always; set Interleave to 1MB; set Prefetch to 6. Also make sure the RAID controller is in an x8 or faster slot.
The default drive timeout Fusion RAID systems is 30 seconds. The default is generally the best, but may be insufficient for some Seagate drives, which in rare instances may not respond within a 30 second timeout and consequently appear as degraded. If you are using Seagate drives, Sonnet recommends setting the timeout to 60 seconds, with the CLI command, "set raidcommandtimeout 60000".
