I've been working on retrofitting an old SCSI Powervault to SAS/SATA. (Yes, silly, but fun!)
The plan is to use an adaptec 3805, switch from internal mini-SAS (SFF 8087) to external mini-SAS (SFF 8088) at the host and back to internal mini-SAS at the backplane and fan out from there.
Will SES-2/SGPIO sidebands persist through the cable changes?
I've been trying trying to find information about it myself, but half of it seems to be conflicting.
I'd assume internal and external would use the same pinouts, but sidebands seem to use vendor-specific pins so I could see them being dropped when needing greater error-resistance in external cabling.
If anyone has seen information about receiving SES-2/SGPIO with a microcontroller or found a place with standalone SGPIO-controllers for sale I'd also be interested
