Blade enclosures in the D-racks are not identified using standard units. A standard unit (SU) or
unit (U) is equal to 1.75 inches (4.445 cm). Enclosures within a rack are identified by the use of
module IDs 0, 1, 2, and 3, with enclosure 0 residing at the bottom of each rack. These module IDs
are incorporated into the host names of the CMC (i0c, i1c, etc.) and the compute blades (r1i0n0,
r1i1n0, etc.) in the rack.
Each rack in a multi-rack system is numbered with a single-digit number sequentially beginning
with (001). A rack contains blade enclosures, administrative and rack leader server nodes, service
specific nodes, optional mass storage enclosures and potentially other options.
Note: In a single compute rack system (D-rack), the rack number is always (001).
The number of the first blade enclosure will always be zero (0). These numbers are used to identify
components starting with the rack, including the individual blade enclosures and their internal
compute-node blades. Note that these single-digit ID numbers are incorporated into the host
names of the rack leader controller (RLC) as well as the compute blades that reside in that rack.
Availability of optional components for the SGI ICE X series of systems may vary based on new
product introductions or end-of-life components. Some options are listed in this manual, others
may be introduced after this document goes to production status. Check with your SGI sales or
support representative for the most current information on available product options not discussed
in this manual.
The optional SGI RS system automatically detects system conditions that indicate potential future
problems and then notifies the appropriate personnel. This enables you and SGI global support
teams to pro-actively support systems and resolve issues before they develop into actual failures.
