Chapter 3. IBM System Storage DS4000 and
DS5000 hardware
This chapter describes the hardware and features of the current IBM System Storage
DS4000 and the DS5000 family, including the new IBM System Storage DS5020 Express.
This section details the DS5000 products, which include the DS5020, DS5100, and the
DS5300. The DS4000 product covered in this section includes only the DS4700 model; for
more details about the older DS4000 models, see IBM System Storage DS4000 and Storage
Manager V10.30, SG24-7010.
The chapter also includes a description of additional hardware components that are essential
for a complete storage solution. These include the new EXP5000 and the EXP520, with
cabling considerations.
The IBM System Storage DS storage subsystem is designed for the rigors of consolidation.
The architecture allows for linear scalability, and it is easy to customize a balanced workload
to fulfill high IOPS and MBps requirements. Replaceable host cards enable modular adoption
for different host interface techniques, such as 4 Gbps FC, 8 Gbps FC, iSCSI, and so on.
