This replaces the long standing PERC4 (which was an OEM LSI / AMI MegaRAID U320) in the [1,2]850 series. Obviously this is an OEM chipset as well. I see it listed in mfi(4). It appears to be backported into RELENG_6. It appears to be an OEM of the HBA ASIC on the LSI Logic products: -MegaRAID SAS 8408E -MegaRAID SAS 8308ELP -MegaRAID SAS 8344ELP -MegaRAID SAS 8408E -MegaRAID SAS 8480E Do we know if ports/sysutils/megarc supports /dev/fmi? The Linux drivers for SUSE/RHEL seems to suggest that the new driver is simply an extension to the existing one, so it seems likely the management interface is the same. I see LSI lists a separate CLI: http://lsi.com/files/support/rsa/MR_SAS_1.0_1.00.07-Linux-MegaCLI.txt http://lsi.com/files/support/rsa/MR_SAS_1.0_1.00.07-Linux-MegaCLI.zip Which is different from where we get the MegaRC "Beta": http://www.lsilogic.com/files/support/rsa/beta/drivers/ (no directory listing support) There were some posts in April that suggested Linux Binary emulation and linux compat "sysfs" or "linprocfs" would be needed instead of a native source code port. I think it's safe to say most people will be disinclined to enable Linux binary emulation on production servers. The controller is pretty much useless without a management CLI. Plus, the last I heard from Dell, there was no chance of integrating RAID management with any out-of-band management API (IPMI,BMC, SNMP, etc.) Also, anyone who may have worked with an 1950/2950 demo unit or non-OEM LSILogic card: has the BIOS menu usability and/or general intelligence of the card has improved? For example, with the PERC 4/e you could pull a component out of a RAID1, power on the system, and the RAID controller would scan the SCSI bus and report all volumes a healthy. TIA, ~BAS
