Optane Memory uses a "least recently used" (LRU) approach to determine what gets stored in the fast cache. All initial data reads come from the slower HDD storage, and the data gets copied over to ...

To prevent CPUs from using outdated data in their caches instead of using the updated data in RAM or a neighboring cache, a feature called bus snooping was introduced.

Typically, a distributed cache is shared by multiple application servers. In a distributed cache, the cached data doesn’t reside in the memory of an individual web server.

Emerging memory technologies like Intel's Optane DC persistent memory, ReRAM, and MRAM will keep more data closer to processing resources.

However in recent years, the cost of memory has been falling, making it possible to put far larger datasets in memory for data processing tasks, rather than use it simply as a cache.

However, this may cause significant overheads for metadata storage and traffic. While using a fixed-size, near-memory cache and compressing data in near memory can help, precious near-memory capacity ...

Currently, TMO enables transparent memory offloading across millions of servers in our datacenters, resulting in memory savings of 20%–32%. Of this, 7%–19% is from the application containers, while ...

IBM Research has been working on new non-volatile magnetic memory for over two decades. Non-volatile memory is wonderful for retaining data without power, but it is extremely slow, and does not ...
