SCSI hba recommendation
|
|
| Felix Engel 2006-11-13, 8:28 am |
| Hello NG,
in order to connect an external RAID system via SCSI to our file server
we are looking for a suitable HBA. Up to now we have tried an Intel
SCRU42E and an Adaptec 29320, but both of them do not support 16 bytes
SCSI CDBs. Therefore they do not support LBA64 addressing, which limits
the volume size to 2TiB at 512 bytes/sector. Since our volumes are
larger, this is not an option for us.
We are therefore looking for recommendations of SCSI host controllers
with the following features:
- U320 transfer rate
- Driver support for CDB16
- Mature driver
- If possible dual channel
- If possible PCI-Express
Any hints will be greatly appreciated.
Regards, Felix Engel

Have a look at the LSI22320. It's PCI-X, but it's dual channel and the
drivers are rather mature. And on the info page they have a blurb saying
that they support >2TiB volumes. You may want to confirm that with their
tech support, but it looks promising.

Just to confirm what Joshua has recommended, we have two LSI 22320's and
they work very well with our > 2TB RAID DAS systems.
