Quick ? for anyone with a SAS-846a backplane (supermicro)

[james23]

Hi, I just swapped out my supermicro BPN-sas-846TQ backplane for a BPN-sas-846a backplane (i went from the backplane which has 24 individual sata inputs, to the backplane version with just 6 x SFF-8087 ports, feeding the 24x attached drives).


My question is about the Blue activity LEDs. on the 846TQ, the blue LEDs were generally off but would blink/flash based upon activity. on the 846A, the blue LEDs are ON, and flash/go off for activity (full activity is the blue led heavily dimmed, almost off, where as on the 846TQ, full activity was the blue LED shinning really bright and solid).

Can someone with a 846A backplane confirm what their drive activity LEDs show for disk activity.

thanks

depends on the drive... I have an 836A which is probably about the same functionally (just 16 instead of 24 ports) and the blue LED is off and blinks for activity EXCEPT with my Intel SSDs, those are on and blink off for activity, but they do that in a lot of backplanes.... it's an issue with the drive itself

My SAS drives show solid blue once they spin up.

Blue after spinup.. darker on disk activity. SATA RE4 and Intel SSD.

with some ST31000424SS on after spin-up , blink on activity other
ST31000424SS off after spin-up blink on activity

@flecom Intel SSDs are strange. They blink off for activity unlike my Samsung or Seagate ones.
