The Raptor ordering page includes some LSI HBAs for SATA / SAS:
- LSI 9300-8i 8-port Internal SAS 3.0 HBA
- LSI 9300-8e 8-port External SAS 3.0 HBA
- MegaRAID 9361 8-port Internal SAS HBA w/ BBU
- MegaRAID 9361 16-port Internal SAS HBA w/ BBU
The non-RAID cards have a PowerPC 476 running firmware from LSI. The RAID cards have some kind of RAID SoC, I haven't looked at the details but it also includes firmware.
Is there any particular reason these are recommended in the ordering process or is source code available now?
Do these cards allow people to replace the firmware or do they expect cryptographically signed blobs from the vendor?
