All new designs are completely compatible with all valid SP configurations using
older equipment. Also, all new nodes can be installed in any existing SP frame
provided that the required power supply upgrades have been implemented in
that frame. The reason for this is that the SMP nodes have higher power
consumption. Therefore, there is a higher power requirement for the frame.
4.1.1 SP frame dimensions
The most noticeable difference between the new and old tall frame is the
reduction in height. Another physical difference is the footprint. Before this new
frame offering, the frame and the first node in the frame were tied together,
forming a model. Each new node that was made available was potentially
installable in the first slot of a frame; so, a new model was born. With the new
offering, IBM simplified the SP frame options by decoupling the imbedded node
from the frame offering. Therefore, when you order a frame, all you receive is a
frame with the power supply units and a power cord. All nodes, switches, and
other auxiliary equipment are ordered separately. Table 4-1 details the SP frame
dimensions, including the base.
Table 4-1 SP frame dimensions
The new tall frame has a height of 75.8 inches (1.9 m), which provides an easier
fit for the entrance doors than the old 79 inches (2.01 m) tall frame. However, it
requires more floor space because the depth of the tall frame is 51 inches (1.3
m), which is 7 inches (0.2 m) greater than the old tall frame. The new Short frame
has the same dimensions as the old short frame.
