I've scoured the search engines
I've looked at vinum and ccd
I need RAID-1 Hardware with instructions how to mirror!
Where is this information?
Mylex, AMI all have cards. Which card to buy? How are they
supported? How do I set them up? Where is the RAID documentation?
Where's the secret cache of all this info?

1. Raid performace issues (Raid 5 vs. Raid 0+1) with database files
Hi folks,
We are thinking to place one of our DB's on a Sun Storedge 5200 and
Sun Enterprise 4500.
Since we have a web-based OLTP environment, well, actually mixed,
since we have major updates running at nights against most of the
data, I thought that RAID-5 is not great, since during the day there
are a lot of small reads/writes.
I was thinking about 0+1 on datafiles with actualy data, but I am not
sure whether I need to mirror the TEMP tablespace or whether I should
place the REDO logs on the mirror.
Any advice would be appreciated.
Thanx
