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.
Do you need a self-contained resilient boot solution that does not impact overall server storage capacity or consume a PCIe slot?
HPE Flash Memory Cards and USB Drives are engineered with enterprise-class high endurance NAND for life within non-stop datacenter environments. Using the highest industry flash technology to provide a higher level of performance and longer endurance characteristics at an enterprise level, each device undergoes rigorous testing and software validation to verify the highest level of quality and reliability while running on HPE ProLiant servers.
