Info about I/O Scheduling and Disk

Hello,

We are currently rolling out SRM 5.0 on Linux RHEL 4 with Oracle 10g as the database.

I was just wondering if anyone has changed the I/O Scheduling to use the Oracle recommended "Deadline" algorithm versus the default "CFQ" Completely Fair Queuing method.

I've had a look around and could not find anything from SAP that says that the Deadline algorithm could be used.

Similarly is anyone using Veritas Volume Manager on RHEL 4 and if so is this ok by SAP for Linux. We use it on our Solaris Servers but am not sure if we can use it on Linux.

Regards,
