Efficiency has been a pivotal aspect of the software industry since its inception, as a system
that serves the end-user fast, and the service provider cost-efficiently benefits all parties. A …

Data storage devices are getting" smarter." Smart Flash storage devices (aka" Smart SSD")
are on the horizon and will package CPU processing and DRAM storage inside a Smart …

Non-volatile memory (NVM) is a new storage technology that combines the performance
and byte addressability of DRAM with the persistence of traditional storage devices like flash …

I/O latency and throughput is one of the major performance bottlenecks for disk-based
database systems. Upcoming persistent memory (PMem) technologies, like Intel's Optane …

For years, the increasing popularity of flash memory has been changing storage systems.
Flash-based solid-state drives (SSDs) are widely used as a new cache tier on top of hard …

Hybrid storage systems (HSS) use multiple different storage devices to provide high and
scalable storage capacity at high performance. Data placement across different devices is …

PCIe-attached solid-state drives offer high throughput and large capacity at low cost. Modern
servers can easily host 4 or 8 such SSDs, resulting in an aggregated bandwidth that hitherto …
