FDE considerations
The Full Disk Encryption feature available via the management interfaces requires use of self-encrypting drives
(SED) which are also referred to as FDE-capable disk drive modules. When installing FDE-capable disk drive
modules, follow the same procedures for installing disks that do not support FDE.
The procedures for using the FDE feature, such as securing the system, viewing disk FDE status, and clearing and
importing keys are performed using the SMC or CLI (see the Storage Manager Guide or CLI Reference Guide for
more information).
NOTE: When moving FDE-capable disk drive modules for a disk group, stop I/O to any volumes in the disk
group before removing the disk drive modules. Follow the procedures in
replacing disk drive modules relative to the enclosure type (2U12/2U24/5U84). Import the keys for the disks so
that the disk content becomes available.
NOTE: For more information, see the topic about the FDE feature in the Storage Manager Guide.
Connecting the controller enclosure and optional expansion enclosures
The DS6200 and DS4200 controller enclosures support up to nine (9) 2U expansion enclosures for a maximum of
240 disk drives. Alternatively, the DS6200 and DS4200 controller enclosures support up to three (3) 5U84
expansion enclosures for a maximum of 276 disk drives.
The DS2200 controller enclosures support up to three (3) 2U expansion enclosures for a maximum of 96 disk
drives. The DS2200 controller enclosure does not support the 5U84 expansion enclosure available for use with
DS6200/DS4200 controller enclosures.
The enclosures support both straight-through and reverse SAS cabling. Reverse cabling allows any drive enclosure
to fail—or be removed—while maintaining access to other enclosures. Fault tolerance and performance
requirements determine whether to optimize the configuration for high availability or high performance when
cabling.
IMPORTANT: RBOD/EBOD cascades
•
The DS6200/DS4200/DS EXP storage system supports intermixing of 2U12 and 2U24 EBODs, but it does not
support intermixing of 2U and D3284 EBODs. EBOD cascades must be all 2U or all 5U enclosures.

The DS2200/DS EXP storage system supports intermixing of 2U12 and 2U24 EBODs, but it does not support
the D3284 EBOD.
