• Enterprise Flash at Less Than $2/Gb
  The Flash Module Device (FMD) unique to HPE XP7 is the driver for industry-leading performance and is designed for those customers seeking the ultimate in storage performance.
  With an XP7 configuration using just 64 FMD's a stellar SPC-1 result of 2M IOPS at .96 ms response time was achieved.
  Inline hardware compression that provides over 2:1 compression ratio with zero performance penalty and a density increase to 14 TB per FMD.
  The XP7 Gen2 FMD is the flash media of choice as 3 million plus IOPS at sub-millisecond response times is what you can expect along with compression savings of over 2:1 when using HPE XP7 Gen2 FMD.
  All this at a price point that trumps traditional SSD media in bit cost.
• Top Performance
  The unique form factor of the FMD allows much higher connect bandwidth to the actual flash devices. This allows the full speed of the FMD to be exploited (utilized) unlike the SSDs that only have access to the "standard disk slot" bandwidth.
  A high-performance compression engine resides in the custom ASIC controller and provides inline hardware compression with zero overhead.
  The compression algorithm is an always-on sliding window LZ77 derivative that delivers real-time compression. Having this compression engine in each and every Gen2 FMD Device allows for unparalleled scalability and performance.
  A degradation in the I/O processing is observed when managing housekeeping tasks and under high write workloads. The FMDs do away with this issue by removing the housekeeping tasks from the IO path.
  The flash controller monitors the number of writes, erasures and refreshes to eliminate these imbalances by balancing the rate of deterioration in the flash memory cells. This helps in extending the useful lifetime of flash.
• Easy Consolidation
  The unique form factor of the FMD does not limit the capacity/density to fit into a spinning media footprint. FMDs are self-contained controller boards currently available in 1.7 TB, 3.5 TB ,7 TB and 14 TB.
  Compression and deduplication bringing unmatched storage efficiency.
  Denser, affordable Flash Devices with built in compression engine in the quad core controller.
• Affordable
  Today's Gen2 FMDs are Devices with always-on compression. This substantially reduces the $/Gb of FMDs. The maximum compression that these devices can provide depends on the application.
  Flash Devices with inline HW compression at cost of HDDs.

The HPE XP7 Flash Module Device is a FMD unique to XP7. It combines MLC NAND flash and a SAS interface with a custom ASIC controller for superior flash performance. The FMD form factor is larger than traditional SSD and therefore is available in capacities of 1.7 TB, 3.5 TB, 7 TB and 14 TB. They are configurable in a variety of RAID types in the same fashion as other drives and is compatible with all XP7 firmware and software features. The XP7 Flash Module Device supports wear levelling. In a flash memory each write or erase cycle stresses the cell which in turn causes deterioration of the cell over time. This might cause an imbalance in the cell activity which creates an irregular distribution of these unstable cells thereby impacting the life of flash. The flash controller monitors the number of writes, erasures and refreshes to eliminate these imbalances by balancing the rate of deterioration in the flash memory cells. This helps in extending the useful lifetime of flash.
