– One midplane or backplane for plugging components that provides
maintenance of flash drives, Expander Modules, and power supplies
Management enclosure
The model 983 contains a management enclosure.
The management enclosure contains the following components:
v Two Hardware Management Consoles (HMCs)
v Two Ethernet switches
v Two power control cards
v Two power supply units (PSUs) to power the management enclosure
v One Local/Remote switch assembly
Management console
The management console is also referred to as the Hardware Management Console
(or HMC). It supports storage system hardware and firmware installation and
maintenance activities.
The HMC connects to the customer network and provides access to functions that
can be used to manage the storage system. Management functions include logical
configuration, problem notification, call home for service, remote service, and Copy
Services management. You can perform management functions from the DS8000
Storage Management GUI, DS command-line interface (DS CLI), or other storage
management software that supports the storage system.
Ethernet switches
The Ethernet switches provide internal communication between the management
consoles and the processor complexes. Two redundant Ethernet switches are
provided.
Processor nodes
The processor nodes drive all functions in the storage system. Each node consists
of a Power server that contains POWER8 processors and memory.
I/O enclosure
The I/O enclosure provides connectivity between the adapters and the processor
complex.
The I/O enclosure uses PCIe interfaces to connect I/O adapters in the I/O
enclosure to both processor nodes. A PCIe device is an I/O adapter.
To improve I/O operations per second (IOPS) and sequential read/write
throughput, the I/O enclosure is connected to each processor node with a
point-to-point connection.
The I/O enclosure contains the following adapters:
Flash RAID adapters
PCIe-attached adapter with four SAS ports. These adapters connect the
processor nodes to enclosures and provide RAID controllers for RAID
support.
Host adapters
An I/O enclosure can support 8 or 16 host ports.
