Drive Tray
Information by
Model
The following tables lists drive tray specifications that might affect your topology.
Make sure that your planned topology is compatible with these specifications and
restrictions.
NOTE When you mix different types of drive trays, you must consider the total
number of drives that are available in the final configuration of the storage array. Your
configuration must meet both the limit on the total number of drives and the limits on
the number of drive trays of a given model.
NOTE The maximum number of drives and the maximum number of drive trays for
a redundant pair of channels is the same as for a single non-redundant channel.
