eXFlash memory-channel storage is the newest innovative flash memory technology from Lenovo, first introduced with System x3850 X6 and x3950 X6 servers. eXFlash memory-channel storage is a high-performance solid-state storage device in a standard DIMM form factor that plugs into existing memory DIMM slots and is directly connected to the DDR3 system memory bus.
This new technology allows supported System x servers to close the performance gap in storage I/O and deliver break-through performance for targeted workloads, such as analytical workloads, transactional databases, and virtualized environments. Lenovo eXFlash DIMMs offer significantly lower latency compared to traditional solid-state devices, such as eXFlash SSDs and even PCIe SSD adapters.
