Hello Exports :

In the case of ZS3-4, the 4x4 ports(SAS-2) 4ea HBAs installed on each controller in max.

ZS3-4 clusters have 8ea 4x4 port HBA, (8ea*4port=32ports).

one single chain used 4 ports on the cluster configuration (each controller used 2 ports for single daisy chain connection).

So 8 daisy chains in max daisy chains on ZS3-4.

ZS3-4 cluster model could be configured 36 DEs in max.

36/8=4.5 (max disk shelves counts are in a single daisy chain)

It should be considered for takeover/failback conditions.

Maximum disk shelves per controller mentioned Max. disk shelves (as 36ea) and Max 4x4 port SAS-2 HBA (4ea)
