Array Configuration
My company just purchased a ML530 w/10 drives and a 2 channel 6x series Smart Array Controller. I would like to know if its possible to configure the following using the default ACU:
disk 1 & 2 - RAID1 (mirror the OS)
disk 3,4,5,6,7 - RAID5 (Databases)
disk 8 & 9 - RAID 1 (mirror log files)
disk 10 - SPARE
Thanks in advance!

Re: Array Configuration
This will provide maximum performance since the bottleneck to storage is the hard disk.
General rule of thumb:
Load balance across all channels (you can RAID across channels not cards)
Use as many drives as possible to create and array
Create Logical drive from the array set.

Re: Array Configuration
Your confusing Array and RAID.
Using an EVEN number of drives create an ARRAY.
*Then*
Create your logical drives (enter the size and the RAID type ├в 0, 1, 5, 5ADG).
**Example**
Drive 1 ├в 100MB
Drive 2 ├в 100MB
Drive 3 ├в 100MB
Drive 4 ├в 100MB
Add 1-4 to ARRAY A (400MB RAW Space)
Create Logical Drive (Logical Drive 1, 50MB RAID 1).
You now have ARRAY a with 300MB RAW space and one drive 50MB-RAID 1 (50MB mirror requires 100MB RAW).
Now you can create a Logical drive with X space using RAID 5.
You have just created 2 virtual RAID sets ├в you do not need to tie physical drives to RAID sets. This allows for maximum performance since I use ALL the drives for
