Chapter 1. Overview
The IBM DS8880 is a high-performance, high-capacity storage system that supports
continuous operation, data security, and data resiliency. For high-availability, the
hardware components are redundant.
DS8880 system types with frames included add a base frame and expansion frame
to the 283x machine type family, and the 533x all-flash machine type family.
Note: The modular rack-mountable system DS8882F model 983 is covered in a
separate publication. For information on the DS8882F model 983, refer to the
DS888F Introduction and Planning Guide (GC27-9259-00).
v The base frame contains the processor nodes, I/O enclosures, Ethernet switches,
and the Hardware Management Console (HMC), in addition to power and
storage enclosures. The HMC is a small form factor computer and uses a
keyboard and monitor that are stored in the base frame. An optional secondary
HMC is also available in the base frame. A secondary HMC can provide
high-availability, particularly for important processes such as encryption, Copy
Services, and the HMC storage management functions.
v Depending on the system configuration, you can add up to four expansion
frames to the storage system. Only the first expansion frame contains I/O
enclosures, which provide more host adapters, device adapters, and High
Performance Flash Enclosure Gen2 flash RAID adapters.
The DS8880 features five system types with frames: DS8884, DS8884F, DS8886,
DS8886F, and DS8888F. The DS8884 (machine type 283x models 984 and 84E) is an
entry-level, high-performance storage system. The DS8884F (machine type 533x
model 984) is an entry-level, high-performance storage system featuring all High
Performance Flash Enclosures Gen2. The DS8886 is a high-density,
high-performance storage system with either single-phase power (machine type
283x models 985 and 85E) or three-phase power (machine type 283x models 986
and 86E). The DS8886F is a high-density, high-performance storage system with
either single-phase power (machine type 533x models 985 and 85E) or three-phase
power (machine type 533x models 986 and 86E) featuring all High Performance
Flash Enclosures Gen2. The DS8888F (machine type 533x models 988 and 88E) is a
high-performance, high-efficiency storage system featuring all High Performance
Flash Enclosures Gen2.
Note: Previously available DS8880 models (980, 98B, 981, 98E, 982, 98F) are still
supported, but not covered in this version documentation. For information on
models not documented here, refer to previous version documentation
(GC27-8525-06).
v The DS8884 (machine type 283x models 984 and 84E) storage system includes
6-core (12-core with zHyperLink support) processors and is scalable with up to
96 Flash Tier 0, Flash Tier 1, or Flash Tier 2 drives, up to 768 standard drives, up
to 256 GB system memory, and up to 64 host adapter ports. The DS8884 includes
a base frame (model 984), up to two expansion frames (model 84E), and a 40U
capacity in each frame.
v The DS8884F (machine type 533x model 984) storage system includes 6-core
(12-core with zHyperLink support) processors and is scalable with up to 192
