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 22 drive enclosures can be installed in the ETERNUS DX500 S4/DX500 S3. Up to 44 drive enclosures can be
installed in the ETERNUS DX600 S4/DX600 S3.
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 22 drive enclosures can be installed in the ETERNUS
DX500 S4/DX500 S3 and up to 44 drive enclosures can be installed in the ETERNUS DX600 S4/DX600 S3.
Drive enclosures can be installed until the total number of drive slots reaches the maximum number that can be
installed (528 for the ETERNUS DX500 S4/DX500 S3 and 1056 for the ETERNUS DX600 S4/DX600 S3). If the num-
ber of drive slots reaches the limit, additional drive enclosures cannot be added.
For example, if twenty 2.5" type drive enclosures are installed in a ETERNUS DX500 S4/DX500 S3, up to two 3.5"
type drive enclosures can be added. However, a high-density drive enclosure cannot be added.
