The DS8888F uses 8 or 16 Gbps Fibre Channel host adapters that run Fibre
Channel Protocol (FCP), FICON, or (for 8 Gbps adapters only) Fibre Channel
Arbitrated Loop (FC-AL) protocol. The High Performance FICON (HPF) feature is
also supported.
The DS8888F supports three-phase power only.
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 DS8888F (models 988 and 88E), depending on the amount of

DS8888F base frame (model 988) overview:
The DS8888F includes a base frame (model 988).
The base frame includes the following components:
v High Performance Flash Enclosures Gen2
v Hardware Management Console (HMC), including a keyboard and monitor
v Second HMC (optional)
v Ethernet switches
v Processor nodes (available with POWER8+ processors)
v I/O enclosures
v Direct-current uninterruptible power supplies (DC-UPS)
v Rack power control (RPC) cards
DS8888F expansion frame (model 88E) overview:
The DS8888F supports up to two expansion frames (model 88E) that can be added
to a base frame. A minimum of 2048 GB system memory and a 48-core processor is
required, if an expansion frame is used.
The first expansion frame includes I/O enclosures. You can add up to six High
Performance Flash Enclosure Gen2 pairs to each expansion frame.
