ADS multi-node server component locations

A 14-node example (1 utility node and 13 active storage nodes) of the initial
configuration of a standard ADS multi-node server is shown here. Initial configurations
range from 4 to 18 nodes (one utility node plus a maximum of 16 active storage nodes
and one optional spare storage node).
When performing remove and replace procedures in this document, use this diagram to
determine component locations.
Figure 1 Multi-Node Layout
Because previous component replacement might have changed the arrangement of
nodes in the rack, always use the instructions in this guide to verify the location of a
defective component before continuing. Since a spare can replace any defective storage
node, and because a replacement node can become the new spare, the location of any
specific storage node can vary over time.
Each rack configuration has 40U capacity. For Gen4T, the utility node takes up a 2U
increment. All storage nodes take up 2U increments. The utility node is at the bottom of a
multi-node configuration, with active storage nodes and an optional spare storage node
stacked above it. Additional nodes can be added in expansion slots starting with the
lowest available slot.
