Shelf Installation Overview - Dell EMC Data Domain FS15 SSD Shelf Hardware Manual

CHAPTER 1

Shelf Installation Overview

ES30 expansion shelves
Adding ES30 expansion shelves to an Data Domain system increases the system's
storage capacity. The expansion shelves are organized by sets (or chains). For regular
DD systems, a set consists of one to four shelves of the same model (either all ES20
or all ES30 shelves). For DD systems with the Extended Retention software option, a
set consists of one to seven shelves of the same model (either all ES20 or all ES30
shelves). For redundancy, a shelf set is usually connected to two separate SAS I/O
modules or HBA cards on the Data Domain controller, and all of the shelves within a
set are connected to each other via dual paths.
FS15 SSD shelf
The FS15 shelf consists of a number of SSD drives, and while the shelf chassis is the
same chassis used in all ES30 products, it can only be used with DD6300, DD6800 and
DD9300, and DD9500 and DD9800 systems configured with DD OS 6.0 and later.
Note
Data Domain systems that support the ES30 shelves must be running DD OS 5.1
l
and later.
For instructions on replacing one of the field replaceable components, see the
l
appropriate ES30 Field Replaceable Unit (FRU) documentation on the Data
Domain Support site. You should assume that any printed copy might be out-of-
date. Therefore, always check the on-line support portal for the latest version of a
FRU document before replacing any part.
Racks are filled from the bottom up.

For details about the SATA and SAS shelves and recommendations for the
l
supported DD OS software and Data Domain systems, see
guidelines on page 21.
SSDs in an FS15 shelf are not RAID-protected.
