Hi, I'm trying to find out which controller card people here recommend that can
drive 8 SATA hard drives and that would work with my Asus M2N-SLI Deluxe
motherboard, which has following expansion slots:
2 x PCI Express x16 slot at x16, x8 speed (PCIe)
The main requirements I have are:
- drive 8 SATA drives
- rock solid reliability with x86 OpenSolaris 2009.06 or SXCE
- easy to identify failed drives and replace them (hot swap is not necessary
but a bonus if supported)
- I must be able to move disks with data from one controller to another of
different brands (and back!), only doing zpool export and import, which implies
the HBA must be able to run in JBOD-mode without storing or modify anything on
the disks. And preferably, the drives must show up with the format command.
- should support staggered spinup of drives preferably
>From limited research I can see that at least the following 3 main
>possibilities exist:
1. Supermicro AOC-SAT2-MV8 (PCI-X interface) (pure SATA) (~$100)
2. Supermicro AOC-USAS-L8i / AOC-USASLP-L8i (PCIe interface) (miniSAS to SATA
cables) (~$100)
3. LSI SAS 3081E-R or other LSI 'MegaRAID' cards (PCIe interface) (miniSAS to
SATA cables) (~$200+)
1. AOC-SAT2-MV8 :
Again, from reading a bit, I can see that although the M2N-SLI Deluxe
motherboard does not have a PCI-X slot, apparently it could take the
AOC-SAT2-MV8 card in one of the PCIe slots, although the card would only run in
32-bit mode, instead of 64-bit mode, and would therefore run slower.
2. AOC-USAS-L8i :
The AOC-USAS-L8i card looks possible too, again running in the PCIe slot, but
the old threads I saw on this seem to talk about some device numbering issue
which could make determining the right failed drive to pull out, a difficult
task -- see here for more details:

3. LSI SAS 3081E-R or other LSI 'MegaRAID' cards :

This forum thread from DEC 2007 doesn't sound too good regarding drive
numbering (for identifying failed drives etc), but the thread is 18 months old,
and perhaps the issues may have been resolved now?
Also I noticed an extra '-R' in the model number I found, but this might be an
omission of the original forum poster -- see here:

I saw Ben Rockwood saying good things about the LSI MegaRAID cards, although
the model he references supports only 4 internal and 4 external drives so is
not what I want -- see here:

Perhaps there are better LSI MegaRAID cards that people know of and can
recommend? Preferably not too expensive though, as it's for a home system :)
If anyone can throw some light on these topics, I would be pleased to hear from
you. Thanks a lot.
