– Reduces custom components and design complexity
– Positions the storage system to reap the benefits of server technology
advances
v Operating environment
– Promotes high availability and provides a high-quality base for the storage
system software through a field-proven AIX operating-system kernel
– Provides an operating environment that is optimized for Power servers,
including performance and reliability, availability, and serviceability
– Provides shared processor (SMP) efficiency
– Reduces custom code and design complexity
– Uses Power firmware and software support for networking and service
functions
System types
Starting with version 8.2.1, DS8880 supports five system types with frames: DS8884
(machine type 283x models 984 and 84E), DS8884F (machine type 533x model
984),DS8886 (machine type 283x single-phase power models 985 and 85E, or
three-phase power models 986 and 86E), DS8886F (machine type 533x single-phase
power models 985 and 85E, or three-phase power models 986 and 86E), and
DS8888F (machine type 533x models 988 and 88E).
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).
For more specifications, see the IBM DS8000 series specifications web
site(www.ibm.com/systems/storage/disk/ds8000/specifications.html).
DS8884 (machine type 283x models 984 and 84E)
The DS8884 is an entry-level, high-performance, high-capacity storage system that
includes standard disk enclosures and High Performance Flash Enclosures Gen2.
DS8884 storage systems feature 6-core (12-core with zHyperLink support)
processors and are scalable and support up to 96 Flash Tier 0, Flash Tier 1, or Flash
Tier 2 drives, and up to 768 standard drives. They are optimized and configured
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:
v Up to 4 standard drive enclosure pairs and up to 1 High Performance Flash
Enclosure Gen2 pair in a base frame (model 984).
v Up to 5 standard drive enclosure pairs and up to 1 High Performance Flash
Enclosure Gen2 pair in a first expansion frame (model 84E).
v Up 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.
