Duplication of data in storage systems is becoming increasingly common. We introduce I/O
Deduplication, a storage optimization that utilizes content similarity for improving I/O …

High-end solid state disks (SSDs) provide much faster access to data compared to
conventional hard disk drives. We present a technique for using solid-state storage as a …

As NAND Flash technology continues to scale down and more bits are stored in a cell, the
raw reliability of NAND Flash memories degrades inevitably. To meet the retention capability …

Using cloud Database as a Service (DBaaS) offerings instead of on-premise deployments is
increasingly common. Key advantages include improved availability and scalability at a …

In data centers, caches work both to provide low IO latencies and to reduce the load on the
back-end network and storage. But they are not designed for multi-tenancy; system-level …

In this paper, we propose a novel hint-accelerated Remote Procedure Call (RPC) framework
based on Apache Thrift over Remote Direct Memory Access (RDMA) protocols, called …

Multilevel caching, common in many storage configurations, introduces new challenges to
traditional cache management: data must be kept in the appropriate cache and replication …

In many of today's applications, access to storage constitutes the major cost of processing a
user request. Data prefetching has been used to alleviate the storage access latency. Under …

Metadata performance in distributed file systems (DFS) is critical, due to the following
trends:(a) the growing size of modern storage systems is expected to exceed billions of files …

We introduce Symbiosis, a framework for key-value storage systems that dynamically
configures application and kernel cache sizes to improve performance. We integrate …
