Only the first expansion frame includes I/O enclosures. You can add up to two
High Performance Flash Enclosure Gen2 pairs to the first expansion frame. The
second, third, and fourth expansion frames do not include I/O enclosures or High
Performance Flash Enclosures Gen2.
The main power area is at the rear of the expansion frame. The power system in
each frame is a pair of direct-current uninterruptible power supplies (DC-UPSs)
with internal batteries.
DS8886 (machine type 283x models 986 and 86E):
The DS8886 (machine type 283x models 986 and 86E) is a high-density,
high-performance, high-capacity storage system that includes standard disk
enclosures and High Performance Flash Enclosures Gen2, and supports three-phase
power.
DS8886 (machine type 283x models 986 and 86E) storage systems are scalable with
up to 24-core processors, up to 192 Flash Tier 0, Flash Tier 1, or Flash Tier 2 drives,
and up to 1,440 standard drives. They are optimized and configured for
performance and throughput, by maximizing the number of device adapters and
paths to the storage enclosures. The frame is 19 inches wide and expandable from
40U - 46U. They support the following storage enclosures:
v Up to 2 standard drive enclosure pairs and up to 2 High Performance Flash
Enclosure Gen2 pairs in a base frame (model 986).
v Up to 4 standard drive enclosure pairs and up to 2 High Performance Flash
Enclosure Gen2 pairs in a first expansion frame (model 86E).
v Up to 9 standard drive enclosure pairs in a second expansion frame.
v
Up to 9 standard drive enclosure pairs in a third expansion frame.
v Up to 9 standard drive enclosure pairs in a fourth expansion frame.
The DS8886 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 DS8886 (models 986 and 86E), depending on the amount of
memory that is available.
