Ultrastar DC ME200 Memory Extension Drive

Scale In-Memory Computing Infrastructure at a Better Total Cost of Ownership


Better TCO for In-Memory Computing Infrastructure with Ultrastar Memory Drive

In-memory computing is used for real-time data processing, application caching, large-scale databases, and acceleration for the data-driven economy. Cloud service providers and IT administrators faced mounting CAPEX and OPEX overhead when deploying in-memory architectures to achieve scalable hardware configurations. To help reduce CAPEX and OPEX for in-memory infrastructure, Ultrastar memory drive increases application memory by creating virtualized memory pools. Ultrastar memory drive scales up to 24TiB in a 1U server for use as virtualized memory without significant loss in application performance. The solution is transparent, requiring no changes to the existing operating systems or applications for near-DRAM performance.

Memory capacity is indicated by GiB and TiB and based on binary values such that one gibibyte (GiB) is equal to 230 bytes and one tebibyte (TiB) is equal to 1024 GiB (240) bytes. Storage capacity and endurance is indicated by TB and PB where one PB equals is 1015 bytes. Accessible capacity can vary from stated capacity due to software, formatting, and other factors.


Suggested expansion of 8x DRAM based on internal performance testing across a variety of industry standard benchmarks.


Endurance rating based on 4KiB random write workload.
