locations
Use "Hard disk drive locations" on page 183 to keep a record of the drives that are
installed in or attached to the DS3500 storage subsystem and EXP3500 storage
enclosure. This information can be helpful when you install additional drives or if
you have to report a hardware problem. Make a copy of this table before you
record information in it, in case you need extra space to write new values later, or
when you update the DS3500 storage subsystem and EXP3500 storage enclosure
configuration.

DS3500 storage subsystem overview

An overview of the DS3500 storage subsystem is provided here.
With direct-attached Serial Attached SCSI (SAS) connectivity and support for RAID
levels 0, 1, 3, 5, and 6, the DS3500 storage subsystem provides an internal physical
storage capacity that is scalable up to 36 TB (terabytes) for the DS3512 and 24 TB
for the DS3524 storage subsystem.
Note: RAID 6 implements a P+Q design. If RAID level 1 is implemented and the
number of drives increases to more than 2, RAID level 10 gets implemented
automatically.
