xii DS8880 Introduction and Planning Guide

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).
vThe 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.
vDepending 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).
vThe 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.

The machine types for the DS8000 series specify the service warranty period. The
warranty is used for service entitlement checking when notifications for service are
called home. All DS8000 series models report 2107 as the machine type to attached
host systems.
Hardware
The architecture of the IBM DS8000 series is based on three major elements that
provide function specialization and three tiers of processing power.
Figure 1 illustrates the following elements:
vHost adapters manage external I/O interfaces that use Fibre Channel protocols
for host-system attachment and for replicating data between storage systems.
vFlash RAID adapters and device adapters manage the internal storage devices.
They also manage the SAS paths to drives, RAID protection, and drive sparing.
vA pair of high-performance redundant active-active Power servers is functionally
positioned between the adapters and a key feature of the architecture.
The internal Power servers support the bulk of the processing to be done in the
storage system. Each Power server has multiple processor cores. The cores are
managed as a symmetric multiprocessing (SMP) pool of shared processing
power to process the work that is done on the Power server. Each Power server
runs an AIX®kernel that manages the processors, manages processor memory as
a data cache, and more. For more information, see IBM DS8000 Architecture and
Implementation on the IBM Redbooks website(www.redbooks.ibm.com/)
The DS8000 series architecture has the following major benefits.

for cost, by minimizing the number of device adapters and maximizing the
number of storage enclosures that are attached to each storage system. The frame
is 19 inches wide and 40U high.
Model 984 supports the following storage enclosures:
vUp to 4 standard drive enclosure pairs and up to 1 High Performance Flash
Enclosure Gen2 pair in a base frame (model 984).
vUp to 5 standard drive enclosure pairs and up to 1 High Performance Flash
Enclosure Gen2 pair in a first expansion frame (model 84E).
vUp to 7 standard drive enclosure pairs in a second expansion frame (model 84E).
The DS8884 uses 8 or 16 Gbps Fibre Channel host adapters that run Fibre Channel
Protocol (FCP), FICON, or Fibre Channel Arbitrated Loop (FC-AL) (for 8 Gbps
adapters only) protocol. The High Performance FICON (HPF) feature is also
supported.
The DS8884 supports single-phase power.
