Eric,
Thanks, I had checked this out earlier but the only non-raid SAS HBAs
(those HBAs that do not end in -R) that are JBOD seem to be external only
(e.g., do not contain any internal SAS ports?)
Justin.
For some of the SAS cards that LSI produce there are 2 sets of firmware
on their site and you can load the non-RAID firmware; both versions
will let you drive stuff as individual drives (e.g. tape drives or
inidivudal discs) but the non-RAID firmware is a LOT faster for that.
Four and eight port LSI cards:

Firmware and BIOS for both Integrated RAID and Initiator-Target. Must
boot to DOS to run utility. Batch file simplifies installation.
Welcome to LSI Logic Integrated SAS Flash Utility
This Utility will upgrade your LSI SAS3442E HBA
Integrated RAID ( IR ) or Initiator ( IT ) Firmware
For IR Type R or r
For IT Type T or t
To Exit Type q
So one just needs to flash the card and use the initiator firmware and
then it will act like a regular (SAS) HBA, no RAID in the card itself, and
then one, presumably could use the card for md/software raid and have
direct access to the disks, no need for exporting disks via JBOD etc?
