(1.75 in.). The U levels are marked on labels on one front mounting rail and one rear
mounting rail.
Important: All DS3500 storage systems are in chassis that are 2U in height.
Figure 3-2 shows an example of the required service clearances for a 9306-900 42U rack.
Check the documentation for the specific rack model that you will use for a statement on the
required clearances.

3.2.2 SAS cables and connectors

All DS3500 storage subsystems, regardless of the optional host attachment feature added
will have SAS host connections available. Also with the addition of any expansion subsystems
they use SAS cabling to attach expansion enclosures. Therefore, let us have a look at the
SAS cables and connectors used.
The SAS ports on the DS3500 controller and EXP3500 ESM all support mini-SAS 4x
multilane connectors. SAS cables with mini-SAS connectors that will fit in these ports are
required, as shown in Figure 3-3 on page 36. IBM provides SAS cables in two cable lengths:
1 and 3 meters.
