DS8888F (machine type 533x models 988 and 88E)

The DS8888F (machine type 533x models 988 and 88E) is a high-performance, high-efficiency, high-capacity storage system that includes only High Performance Flash Enclosures Gen2.

DS8888F storage systems (machine type 533x models 988 and 88E) are scalable with up to 48-core processors, 16 High Performance Flash Enclosures Gen2 pairs, and up to 768 High Performance Flash Enclosure Gen2 flash drives or High Capacity Flash Drives. They are optimized and configured for cost. The frame is 19 inches wide with a 46U capacity. They support the following storage enclosures:
  • Up to 4 High Performance Flash Enclosure Gen2 pairs in the base frame (model 988).
  • Up to 6 High Performance Flash Enclosure Gen2 pairs each in the first expansion frame (model 88E).
  • Up to 6 High Performance Flash Enclosure Gen2 pairs each in the second expansion frame.

The DS8888F uses 8 or 16 Gbps Fibre Channel host adapters that run Fibre Channel Protocol (FCP), FICON®, or (for 8 Gbps adapters only) Fibre Channel Arbitrated Loop (FC-AL) protocol. The High Performance FICON (HPF) feature is also supported.

The DS8888F supports three-phase power only.
