I'd strongly recommend ARECA controllers. The independent, out of band management is really critical.
It just so happens that I'm a reseller lol. Let me know if you want a quote on a 1880!

I have build my solution just 2 month ago. My bust suggestion is to use Intel/LSI card like the RMS25PB080 + the FAST PATH I/O that enable SSD cache. It works great, it's compatible with Open-e. Performance are great. My configuration is based on a entry level server with a Xeon E3 + the raid above and 6HDD in RAID 10 + SSD cache. Easy to configure and easy to manage.

LSI RAID Controller Firmware 5.6 not compatible with Open-E
Just one hint for LSI Megaraid owners: Don´t upgrade your card to the 5.6 Firmware ! It is not compatible at the moment with Open-E Version 7.0up07.xxxx.7356 2013-02-15 b7356 and earlier. The volumes are not recognized at all. ! If you buy a Card with the new software installed you have to downgrade to 5.5. This can be done with a special flag called "noverchk" for the MegaCli command: "MegaCli -adpfwflash -f <older fw file name> -noverchk -a0"

Which card are you talking about ?
Changing the firmware code that drastically would be a first for LSI.

I am talking about the whole MegaRAID Line, like the MegaRAID 924x, 926x, 927x and 928x RAID Controllers. The new driver MR 5.6 (Linux Version 6.506.00.00-2) is out from Mar 02, 2013 and replacing the MR 5.4 (Linux Version 6.504.01.00-02) from Oct 08, 2012. The funny thing is that you recently released a "new" LSI Driver on April 04, 2013 in your "Engineering Phase" section but is was still the old 6.504.01.00-02 driver from last year....Originally Posted by Gr-R
So, yes this is drastic code change and the warning is still active....

I am using a 9271-8iCC and 9266-8i (plus CacheCade). The volumes are recognized, but the performance is unexpectedly slow. Is this related?

Quick question, what would the settings ( Read Policy, Cache Policy,Disk Policy, write policy etc..) be for the SSD Cache Virtual disk in open-e and then what would the settings for the other virtual disks that is associated with the SSD Cache virtual disk.

recommended for LSI w/BBU
-write policy: write-back caching
-read policy: readahead
-Cache Policy: Cached
-Disk cache policy: Enabled
