Sun StorageTek 5220 NAS Appliance Getting Started Guide • October 2006
Cabinets, Racks, and Rail Kits
The Sun StorageTek 5220 NAS Appliance can be installed in the Sun™ Rack 900, the
Sun™ Rack 1000, or third-party racks that comply with the requirements. Although
the system is installed in a single cabinet or rack, the appliance and the back-end
storage units require different rails to support them.
Note –
A cabinet is a rack with a door and the two terms are used interchangeably.
Requirements for Racks and Cabinets
Requirements to support installation of the storage system:
■
The rack’s horizontal opening and unit vertical pitch must conform to ANSI/EIA
310-D-1992 or IEC 60927.
■
Rack must have four-post structure to allow mounting at both front and back.
■
Distance between front and back mounting planes must be between 61 cm and
92 cm (24 to 36 inches).
■
Clearance depth at front (distance between front cabinet door and front mounting
plane) must be at least 2.6 cm (1 inch).
■
Clearance depth at back (distance between front mounting plane to the back
cabinet door) must be at least 80 cm (31.5 inches).
■
Clearance width (distance between the left and right structural supports, cable
troughs, and so on within the front and back mounting planes) must be at least
46 cm (18 inches).
Rack density varies widely based on systems installed, power distribution
installation (in-cabinet, external), power source (single-phase, three-phase), and
whether redundant power is required. Some rack vendors do not support a fully-
loaded rack because of the amount of power required. For power specifications, refer
to
Appendix A
.
Requirements for Rail Kit
Note –
Not all third-party racks are compatible with these slide rail kits.
