I'm getting ready to order the Controllers and HDD for our new server. I'm
going with Serial ATA HDDs. I'm going to have Three (3) arrays on two 8 port
Controllers. Controller 1 will have OS as Raid 10 with hot spare (5 drives
total) and Data 2 as Raid 1 with Hot Spare (3 drives total). Controller 2
will have Data 1 as Raid 10 with Hot Spare ( 7 drives total). If I
understand my Raid capacity correctly and all HDD are 120 GB then OS drive
will be 240 GB, Drive Data 2 is 120GB and Drive Data 1 is 360 GB. Is this
correct?
Yes the Controllers support multiple arrays. I also my switch to 3
controllers cost is driving this to Two at the moment.
I was going to make Data 1 Raid 5 but then read about the write limitations
so I thought Raid 10 would be better. I went with SATA HDD instead of SCSI
do to cost and I want some RAID. Right now we have a 20GB EIDE for DATA 1
and a 30GB for DATA 2 on a single PII 400 MHz system. For the price (3)
147GB SCSI I can buy the fifteen 120 GB SATAs.
