Isn’t their chart wrong?  It shows RAID 5 as “very high” and “very high” while RAID 0+1 is only “high” and “very high” which would seem to indicate RAID 5 is better and uses less disks.  Looks like a typo ???

Here’s a good high level view of RAID levels…   http://www.raidweb.com/whatis.html

 

I use their 8 drive SATA SCSI interface units with RAID 0+1 with my SQL servers and RS/6000 AIX servers.   Performance is two to three times any DELL or IBM raid arrays I’ve used.

 

 

Please note in real world usage I’ve seen RAID 0+1 well out run any RAID 10 array.

Hello All:

 

I haven't gotten any responses to any of my other questions that I've sent to the group, hopefully this one will.

 

I'm trying to spec out a new server and had a question for the group in regard to HDD configuration.  What kind of RAID setup works best on a mid-size Imail installation?  Is RAID-1 acceptable or is RAID-5 recommended? Also, would 15K RPM disks make a huge difference as opposed to 10K RPM disks?

 

Thanks,

Jim Frasch
