MSA 2060 Fault-tolerant cabling (mini-SAS)?

MSA 2060 Fault-tolerant cabling (mini-SAS)?

Is "Fault-tolerant cabling", for enclosures, available in the MSA 2060? 

The MSA 2040 and 2050 documentation shows diagrams of "Fault-tolerant cabling", but the MSA 2060 only shows "Straight-through cabling".   Fault tolerant allows you to cable A-2,3,4.5... and B-5,4,3,2.  If you only can do "Straight-through cabling" for A/B, then if you lost access, for example, of enclosure #3, you cannot access enclosure #4,#5, whereas in "Fault-tolerant cabling", you would still have access to #4,#5.  I just want to understand, if it's not available, why.

Hello @abnegated ,

MSA 2060 no longer supports ‘fault-tolerant’ SAS cabling for disk enclosures, it only supports 'straight-through' cabling.

Fault-tolerant cabling does not provide any meaningful increase to availability and is slightly less performant.

For more information on cabling, please refer to this QuickSpecs.

Thanks,
Sahana S.
