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 …

A unique merit of a solid-state drive (SSD) is its internal parallelism. In this article, we
present a set of comprehensive studies on understanding and exploiting internal parallelism …

Flash solid-state drives (SSDs) are changing the I/O landscape, which has largely been
dominated by traditional hard disk drives (HDDs) for the last 50 years. In this paper we …

TPC-E is a new OLTP benchmark recently approved by the Transaction Processing
Performance Council (TPC). In this paper, we compare TPC-E with the familiar TPCC …

The use of flash-based solid state drives (SSDs) in storage systems is growing. Adding
SSDs to a storage system not only raises the question of how to manage the SSDs, but also …

Considering the current price gap between disk and flash memory drives, for applications
dealing with large scale data, it will be economically more sensible to use flash memory …

A key feature of database systems is to provide transparent access to stored data. In
distributed database systems, this includes data allocation and fragmentation. Transparent …

As storage systems become increasingly heterogeneous and complex, it adds burdens on
DBAs, causing suboptimal performance even after a lot of human efforts have been made. In …

Data warehouses have been traditionally optimized for read-only query performance,
allowing only offline updates at night, essentially trading off data freshness for performance …

Caching is an important optimization in search engine architectures. Existing caching
techniques for search engine optimization are mostly biased towards the reduction of …
