High Performance Disk Subsystem

High Performance Disk Subsystem

Post by Scott Ho » Fri, 08 May 1992 06:37:30

We are currently using a 950 to provide (Oracle) database service for a small
demand application. However, in the near future, we will be adding other
applications which will present significant user load. In order to handle this
load, I would like to consider either the purchase of additional SCSI
interfaces (all our disks are on one SCSI) or a couple of 9333 Disk Subsystems.

My questions are this - has anyone had experience moving from SCSI to the
9333 and if so, what kind of performance changes did you notice? Were they
what you expected?  I am trying to get a feel for which will give the better
price/performance - adding a couple of more SCSI channels, or replacing our
current SCSI disks with the Serial subsystem.

This is my signature. There are many like it, but this one is mine.

1. Tuning Linux for high-speed disk subsystems

Eh, we do 60-70 MB/s reads and 110-120 MB/s writes on our RAIDs... from

I'd say you should get rid of your compaq raid controller and use a
regular SCSI-controller - 66Mhz 64 bit. (e.g. an adaptec)
