Folks,
I am hoping to start a thread where users post their experiences with
various RAID and SCSI controllers running Postgres. When completed,
I'll post it somewhere on Techdocs with a big disclaimer. I'll start it
off:
MYLEX AcceleRAID 170: Not supported under Linux 2.4 kernels.
Performance under RAID 5 with 3 Maxtor UW SCSI disks good on read
operations (slightly better than a single SCSI disk) but on large write
operations poor, similar to low-end IDE disks in having disk-acccess
bottlenecks. Suspected in our installation of locking up on very large
simultaneous read/write operations, such as data tranformations on
tables over 1 million records. (cause of lockup not firmly determined
yet). (Josh Berkus 11/2002)
