Drive cabling topologies for the E5700 controller shelves
and the EF570 flash arrays
The E5700 controller shelf models are the E5724 and E5760. The total number of drive bays in the
storage array, including the drive bays in the controller shelf and those in the drive shelves, must not
exceed 480. The total number of shelves (controller shelves and drive shelves) in a storage array must
not exceed eight.
You can cable E5700 controller shelves to SAS-3 drives shelves (DE460C or DE224C), SAS-2 drive
trays (DE6600 or DE5600) or combinations of SAS-2 and SAS-3 drive shelves. Use cables with
mini-SAS HD (SFF-8644) connectors to connect SAS-3 drive shelves. Use cables with a mini-SAS
(SFF-8088) connector on one end and a mini-SAS HD connector on the other end to connect SAS-2
drive shelves to the controller shelf. Use cables with a mini-SAS connector on both ends for
connections between SAS-2 drive shelves.
Note: When you install SAS cables, make sure that the blue tabs on the SAS cables face the
bottom of the tray or shelf and that each connector clicks into place.
When you cable a mix of SAS-2 and SAS-3 drive shelves to the same controller shelf, you should use
a dual-stack configuration. Put all of the SAS-3 drive shelves in one stack and all of the SAS-2 drive
shelves in the other stack. Attach expansion port 1 from each controller to the SAS-3 stack and
expansion port two from each controller to the SAS-2 stack.
The EF570 controller shelf can be cabled to the DE224C drive shelves. The total number of drives in
the storage array, including the drives in the EF570 controller shelf and those in all of the attached
drive shelves, must not exceed 120. The total number of trays in the storage array, including the
EF570 flash array and all of the attached drive trays, must not exceed five. The drive shelves must
contain only solid-state disks (SSDs).
Note:
When utilizing a E5700 controller in SAS-2 enclosures, support for base host ports is
disabled. For more information on performing upgrades, refer to the E-Series Systems Controller
Upgrade Guide.
