Drive shelf or drive tray cabling
A controller shelf (controller-drive tray) along with any drive shelves (drive trays) that are attached to
it, comprise a storage array. When a storage array includes drive shelves, each controller in the
controller shelf is connected to an environmental services module (ESM) for SAS-2 connections, or
to an I/O module (IOM) for SAS-3 connections in a drive shelf.
The ESMs/IOMs in drive shelves are either connected to a controller in the controller shelf or to an
ESM/IOM in another drive shelf. Correct drive shelf cabling is important because it affects both data
availability and the performance of a storage array. This chapter provides examples of cabling
between a controller shelf and one or more expansion drive shelves. See
on
page 22 for figures that show the port locations on the specified controller shelf and drive shelf
models that you are connecting.
Drive shelf (drive tray) information by model
Certain shelf specifications might affect your choice of cabling topology. Make sure that your
planned topology is compatible with applicable specifications and restrictions.
When you mix different types of drive shelves, you must consider the total number of drive slots that
are available in the final configuration of the storage array. Your configuration must meet both the
limit on the total number of drive slots and the limits on the number of drive shelves of a given
model.
The maximum number of drive slots and the maximum number of drive shelves for a redundant pair
of channels is the same as for a single non-redundant channel.
Each storage array must contain at least one drive. For drive trays and controller-drive trays with a
60-drive capacity, each of the front four bays in each of the five drawers must have a drive installed,
for a minimum of twenty drives.
