The Ultrastar DC ME200 Memory Extension Drive can be used to immediately scale existing
system memory, promote server consolidation, and reduce the complexity of splitting large
multi-TB data sets across multiple servers. The Ultrastar memory drive drives applications
with large amounts of system memory at a fraction of the cost of DRAM by combining
Ultrastar NVMe™ SSDs with Western Digital memory extension technology. Advanced
software algorithms work to maintain DRAM-like performance across a variety of applications,
especially targeting highly parallel workloads with high numbers of transactions. Once
installed, the solution is transparent, requiring no changes to the existing OS and applications.
This document provides details for users and administrators on the design, installation,
features, and specifications of Ultrastar memory drives.
As shown in Figure 1-1, the Ultrastar memory drive executes directly on the hardware, below
the operating system, and creates a hybrid system memory from DRAM and NVM. This hybrid
system memory operates transparently as volatile system memory, as if it were all DRAM.
