Base frame (model 985) overview:
The DS8886 (model 985) includes a base frame.
The base frame includes the following components:
v Standard storage enclosures
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
Expansion frame (model 85E) overview:
The DS8886 supports up to four expansion frames (model 85E) that can be added
to a base frame (model 985). A minimum of 256 GB system memory and a 16-core
processor is required, if expansion frames are added.
The first expansion frame supports up to 240 2.5-inch standard disk drives. The
second and third expansion frames support up to 432 2.5-inch standard disk
drives. A fourth expansion frame supports an extra 288 2.5-inch standard disk
drives. When all four frames are added, the DS8886 can support a total of 1,536
2.5-inch disk drives in a compact footprint, creating a high-density storage system
and preserving valuable floor space in data center environments.
