New R640 with BOSSUS ssd - disk status report?
Recently installed a batch of R640s that came with with a pair of SSD model "SSDSCKJB480G7R". Im looking about for a way to check the health of these via OME, nagios, snmp or other.
- The "smartctl" tools don't seem to support these.
- Using "check_openmanage" (via nagios) doesn't detect the storage (via SNMP). Gives this error:
"SNMP ERROR [storage / channel]: The requested entries are empty or do not exist."
- I can get some info via omreport:
# omreport storage pdisk controller=0
List of Physical Disks on Controller BOSS-S1 (Embedded)
Controller BOSS-S1 (Embedded)
ID : 0
Status : Ok
Name : Physical Disk 0
State : Online
Power Status : Not Applicable
Bus Protocol : SATA
Media : SSD
Part of Cache Pool : Not Applicable
Remaining Rated Write Endurance : 100%
Failure Predicted : No
Revision : N201DL43
Driver Version : Not Applicable
Model Number : SSDSCKJB480G7R
Wondering if there is some other way to monitor these using "standard" OSS methods.

Hello
It looks like the those are M.2 NVMe drives in a Boot Optimized Server Storage controller. There is a section in the manual of the BOSS card that lists the supported management applications. More detailed information about the available management tasks can be found in documentation for those applications. Links to the applications are in the BOSS manual.

That's better than nothing, but it dodges the fact that this lack of support for the *industry standard tool* is a serious red flag. I'll assume that the BOSS-S2 has the same design flaw and avoid it in favor of rear bays for boot drives.
I guess this explains why BOSS is so expensive, and is IMHO a design flaw. HBA RAID is an anachronism best left in 1995. MD RAID is far easier to manage, less expensive, and works better.
