Storage device layout
– To conveniently maintain and operate a controller enclosure, install it in the middle
of the cabinet (15 U to 25 U).
– Reserve 2 U space above and below the controller enclosure to install the cable tray
(also to facilitate the operation of removing and inserting the modules in the
controller enclosure).
– Symmetrically install disk enclosures above and below the controller enclosure.
– Do not stack disk enclosures. Enable five disk enclosures to form a group. In a
cabinet, reserve at least 1 U space between disk enclosure groups for easier
management and minimum vibration transfer.
– Reserve 2 U space at the bottom of the cabinet to facilitate cabling, ventilation and
heat dissipation, and maintenance of the devices in the lower part of the cabinet.
Switch layout
– Install two SNS2248 switches into two cabinets respectively or the same cabinet in
a data center. Use different power supplies to provide power for them.
– Reserve 1 U space below each switch for cabling.
