DS8910F model 994
The DS8910F model 994 is an entry-level, high-performance, high-capacity storage system that includes
only High Performance Flash Enclosures Gen2.
Model 994 features 8-core processors and is scalable and supports up to 192 Flash Tier 0, Flash Tier 1, or
Flash Tier 2 drives. The frame is 19 inches wide and 40U high. It supports up to four High Performance
Flash Enclosure Gen2 pair.
The DS8910F model 994 uses 16 or 32 Gbps Fibre Channel host adapters that run Fibre Channel Protocol
(FCP) or FICON
®
. The High Performance FICON (HPF) feature is also supported.
Model 994 supports single-phase and three-phase power.
The following tables list the hardware components and maximum capacities that are supported for the
DS8910F model 994, depending on the amount of memory that is available.
