Thanks. Okay, i just had a quick look at the spec and yes, it's quite
different to SAF-TE.

I don't have any SES devices to test on but I may think about
abstracting saftemon to handle
more than one protocol for inquiring enclosures. The SES attributes
match pretty closely although
SES is s superset of SAF-TE.

It probably makes sense to include SMART, SAF-TE and SES monitoring into
s single
consistent package. I'm not using SMART as with most RAID controllers,
you only see logical
devices and have no contact directly with the drives (unless you use
SCSI passthrough APIs
althoug these are different from one RAID controller driver to the next).
