The expansion frame includes I/O enclosures. You can add up to four High
Performance Flash Enclosure Gen2 pairs to the expansion frame.
The main power area is at the rear of the expansion frame. The power system in is
a pair of direct-current uninterruptible power supplies (DC-UPSs) with internal
batteries.
DS8886F (machine type 533x models 986 and 86E):
The DS8886F (machine type 533x models 986 and 86E) is a high-density,
high-performance, high-capacity storage system that includes High Performance
Flash Enclosures Gen2, and supports three-phase power.
DS8886F (machine type 533x models 986 and 86E) storage systems are scalable
with up to 24-core processors, and up to 384 Flash Tier 0, Flash Tier 1, or Flash Tier
2 drives. They are optimized and configured for performance and throughput by
maximizing the number of paths to the storage enclosures. The frame is 19 inches
wide and 46U high. They support the following storage enclosures:
v Up to 4 High Performance Flash Enclosure Gen2 pairs in a base frame (model
986).
v Up to 4 High Performance Flash Enclosure Gen2 pairs in an expansion frame
(model 86E).
The DS8886F 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.
For more specifications, see the IBM DS8000 series specifications web
site(www.ibm.com/systems/storage/disk/ds8000/specifications.html).
The following tables list the hardware components and maximum capacities that
are supported for the DS8886F (models 986 and 86E), depending on the amount of
memory that is available.
