Mirror RAID IDE->IDE or IDE->SATA ok?
Posted on 2004-11-01
I'm building up a new server. It will run Win 2003 Server OS.
2 - 120gb IDE's
2-4 - 200gb SATA
I'm running the on-board SATA controller in Basic Mode, I.e. no RAID used on the Mother board.
Raid configuration will be via the OS
The question: For the OS I will partition 60gb or so and use RAID1. Should I mirror it to the other IDE drive or a partition on an SATA drive?
For data I'll use RAID5, again inside the OS. Can (and should I) use partitions in only the SATA drives or is using IDE and SATA in a mixture ok.
I'm thinking of 60gb partitions on all drives for the RAID5 and another set using the balance of the SATA's. If I go 4, I will leave 1 as hot spare if Win2003 will make use of it. If not I'll add it to the array.
Hopefully I'm making some sense. I'm currently reading all the other postings re RAID and 2003 but thought I'd ask my specific in the meantime.
Should I be using the controllers/motherboard raid capabilities? I've been bitten a few times by hardware changes making a raid mirror useless, hence the apprehension.
Thanks in advance for your help
