DS8910F Rack Mounted model 993

The DS8910F Rack Mounted storage system is an entry-level, high-performance storage system that includes only High Performance Flash Enclosures Gen2.

The DS8910F Rack Mounted storage system can be integrated into an IBM Z or IBM LinuxONE, or another standard 19-inch wide rack that conforms to EIA 310D specifications to take advantage of the DS8910F advanced features while limiting datacenter footprint and power infrastructure requirements. This modular rack-mountable enterprise storage system features 8-core processors and supports one High Performance Flash Enclosure Gen2 pair with the IBM Z or IBM LinuxONE installation, or up to two High Performance Flash Enclosure Gen2 pair with the standard 19-inch wide rack installation, with up to 96 Flash Tier 0, Flash Tier 1, or Flash Tier 2 drives. The modular system contains processor nodes, an I/O Enclosure, High Performance Flash Enclosures Gen2, and a Management Enclosure (which includes the HMCs, Ethernet Switches, and RPCs). The HMCs are small form factor computers. The DS8910F Rack Mounted storage system requires a minimum of 15U contiguous rack space.

The standard 19-inch wide rack installation (feature code 0939) supports optional features that require additional contiguous space:
  • A second High Performance Flash Enclosure Gen2 pair (feature code 1605) requires an additional 4U contiguous space.
  • A 1U keyboard and display (feature code 1765) requires an additional 1U contiguous space. For accessibility, the keyboard and display must be mounted at a height of 35 - 46 inches. If you add the keyboard and display, ensure that you provide adequate space to accommodate them.
    Note: The model 993 can also be connected to an existing keyboard with touchpad and display in the frame. The keyboard must include a touchpad because the management console does not accommodate connection for a mouse.

The DS8910F model 993 uses 16 and 32 Gbps Fibre Channel host adapters that run Fibre Channel Protocol (FCP) or FICON® protocol. The High Performance FICON (HPF) feature is also supported.

The DS8910F model 993 supports single-phase and three-phase power. The C13/C14 power cords for connection of the model 993 components to IBM iPDU features or to customer supplied rack PDUs are provided with the components. 1 m jumper C13/C14 power cables are also provided.

The following tables list the hardware components and maximum capacities that are supported for the DS8910F model 993.
Table 1. Components for the DS8910F model 993
Processors System memory Processor memory I/O enclosure Host adapters (4 port) High Performance Flash Enclosure Gen2 pairs1
8-core 192 GB 96 GB 1 2 - 8 1 or 22
8-core 512 GB 256 GB 1 2 - 8 1 or 22
  1. High Performance Flash Enclosures Gen2 are installed in pairs.
  2. The standard 19-inch wide rack installation (feature code 0939) supports an optional second High Performance Flash Enclosure Gen2 pair (feature code 1605). The optional second High Performance Flash Enclosure Gen2 pair is not available with the IBM Z installation (feature code 0937) or the IBM LinuxONE installation (feature code 0938) because there is not enough available space.
