DS8886 (machine type 283x models 985 and 85E or 986 and 86E)
The DS8886 is a high-density, high-performance, high-capacity storage system that
includes standard disk enclosures and High Performance Flash Enclosures Gen2.
The DS8886 models 985 and 85E support single-phase power. The DS8886 models
986 and 86E support three-phase power.
DS8886 (machine type 283x models 985 and 85E):
The DS8886 (machine type 283x models 985 and 85E) is a high-density,
high-performance, high-capacity storage system that includes standard disk
enclosures and High Performance Flash Enclosures Gen2, and supports
single-phase power.
DS8886 (machine type 283x models 985 and 85E) 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 1,536 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 3 standard drive enclosure pairs and up to 2 High Performance Flash
v Up to 5 standard drive enclosure pairs and up to 2 High Performance Flash
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 6 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 985 and 85E), depending on the amount of
memory that is available.
