The overall positioning of the DS4000/DS5000 series within the IBM System Storage DS
family is shown in Figure 1-2. It expands the IBM Midrange System Storage offering in terms
of performance and scalability.

Within the IBM Midrange storage series, the DS5000 models of storage servers support Fibre
Channel (FC), Serial ATA (SATA), Full Disk Encryption (FDE) disk drives, and Solid State
Drives (SSD), and the DS4000 models supports both FC and SATA disk drives.
In terms of capacity, the maximum raw SATA storage capacity is 448 TB, using 1TB SATA
DDM drives. The maximum raw FC storage capacity is 268.8 TB (using 600 GB 15K 4 Gbps
FC DDM).
1.2 IBM Midrange System Storage storage server models
The IBM Midrange System Storage series of storage servers (DS4000 and DS5000) uses
Redundant Array of Independent Disks (RAID) technology. RAID technology is used to
protect the user data from disk drive failures. DS storage subsystems contain Fibre Channel
(FC) interfaces to connect the disk drive enclosures, which contain iSCSI or Fibre Channel
(FC) interfaces to connect the host systems.
The storage servers in the DS5000 series provide high system availability through the use of
hot-swappable and redundant components. This is crucial when the storage server is placed
in high-end customer environments, such as server consolidation on Storage Area Networks
(SANs).
At the time of writing, the IBM Midrange System Storage storage series is composed of five
products that are available in specific models. These products are named DS4700, DS5020,
DS5100, and DS5300, which offers balanced performance, and linear IOPS scalability
supports workloads ranging from departmental to bandwidth-intensive.
