Marketing description

HPE IO Accelerator for ProLiant Servers is a direct attach solid state storage technology PCIe card based solution for application performance enhancement. Based on Multi-level cell (MLC) and Single Level Cell (SLC) NAND Flash technology these devices are ideal for markets and applications requiring high transaction rates and real-time data access.

Product features

• Single Level Cell and Multilevel Cell
  NAND technology uses flash memory cells to store data. Single level Cell (SLC) stores one bit per cell, while Multi-level Cell (MLC) uses two bits per cell. While MLC can store more data within each device, it has lower endurance characteristics than SLC.
• IO and read/write performance
  HPE PCIe IO Accelerator products offer superior IO performance (over 100,000 IOPs on certain products), and high read and write performance with SLC models.
• Latency
  HPE PCIe IO Accelerator offers very low latency access to data (as low as 50 microseconds to read a 4K block on SLC based products and 80 microseconds for MLC based products), in other words a virtually zero seek time compared to rotating magnetic media.
• Data integrity
  Using advanced ECC techniques, the IO Accelerator can correct up to 11 bits out of every 240 bytes, with a design target of a 1 in 10 to the 20th power probability of uncorrectable data and a 1 in 10 to the 30th power probability of undetected bad data.
