Key-value caching is crucial to today's low-latency Internet services. Conventional key-value
cache systems, such as Memcached, heavily rely on expensive DRAM memory. To lower …

Host-aware shingled magnetic recording (HA-SMR) drives deliver higher disk capacity and
expose internal zones to host, but their performance can be severely degraded when …

Flash-based key-value caching plays an important role in Internet services. Compared to in-
memory key-value caches, flash-based key-value caches can provide a 10 to 100 times …

Integrating solid-state drives (SSDs) and shingled magnetic recording (SMR) drives can
build cost-effective hybrid storage systems. However, both SSD and SMR drives endure …

Gemini is a distributed crash recovery protocol for persistent caches. When a cache instance
fails, Gemini assigns other cache instances to process its reads and writes. Once the failed …

In multi-tier storage systems, moving data from one tier to the next can be inefficient. And
because each type of storage device has its own idiosyncrasies with respect to the …

The key-value database engine, which offers higher efficiency, scalability, availability, and
usually works with simple NoSQL schema, is becoming more and more popular. It has been …

Driven by the growing demands from big-data applications, the focus of their data
management has been largely shifted from traditional SQL databases to NoSQL (Not-only …
