Drive Enclosures

This section explains the installation conditions for drive enclosures.
When only one controller is installed in the controller enclosure, high-density drive enclosures
cannot be installed.
■
Types of Drive Enclosures
There are three types of drive enclosures that correspond to available drive sizes (2.5", 3.5", and
high-density 3.5").
Twenty-four 2.5" drives can be installed in a single 2.5" type drive enclosure.
Twelve 3.5" drives can be installed in a single 3.5" type drive enclosure.
Sixty high-density 3.5" drives can be installed in a high-density drive enclosure.
■
Number of Installable Drive Enclosures
Up to ten drive enclosures can be installed.
The number of each type of drive enclosure that can be installed is shown below.

High-density drive enclosures
If different types of drive enclosures are installed, up to ten drive enclosures can be installed in the
ETERNUS DX.
Drive enclosures can be installed until the total number of drive slots reaches the maximum num-
ber that can be installed (144 for the ETERNUS DX100 S4/DX100 S3 and 264 for the ETERNUS
DX200 S4/DX200 S3). If the number of drive slots reaches the limit, additional drive enclosures can-
not be added.
For example, if four 2.5" type drive enclosures are installed in a ETERNUS DX100 S3 (2.5" type CE),
up to two 3.5" type drive enclosures can be added. However, a high-density drive enclosure cannot
be added.

I/O Module

Up to two I/O modules can be installed in a drive enclosures.
