RE: Boot from RAID5 or separate HDD?

["Ian Lowe" <ianlowe@xxxxxxxxxxxxxxxxx>]

I'd suggest a smaller mirror pair for the OS, and a big Raid 5 stripe
for
the data.

I use 2 old 80Gb IDE drives mirrored on the onboard controller for my media
server, and all the rest of the disks RAID-5'd on the actual raid
controller. (no apps or anything get installed on the RAID5, only data)

It's a good idea to separate the OS and apps from the Data- it means the
data can be trivially moved to another server/NAS at a later date without
breaking anything.

If you use DFS it becomes even slicker still.

Subject: [ukha_d] Boot from RAID5 or separate HDD?

Can anyone enlighten me with the current thinking behind where to boot from
on a RAID5 system - array or separate HDD? I'd really like everything
stored
on the array to benefit from the RAID features but are there any down sides
to this?

The array will hold all my home/office data, MP3 collection, HA data etc
and
will have a hot spare (5 x 500Gb SATA-II HDD's)

Thanks,

Paul.
