The controller node has two 90GB SSDs that I plan to use as a bootable RAID1 system disk. What is the preferred method for laying out the RAID array?
a server makes very little use of its system disks after its booted, everything it needs ends up in cache pretty quickly. and you typically don't reboot a server very often. why waste SSD for that?
I'd rather use SSD for something like LSI Logic's CacheCade v2 (but this requires you use a LSI SAS raid card too)
Just add to this comment that you can also use the SSD drives to store the logs/journals/metadata/whatever_you_call_it.
As an example, with XFS you would use the -l option.
