As byte-addressable, high-density, and non-volatile memory (NVM) is around the corner to
be equipped alongside the DRAM memory, issues on enabling the important key-value …

Utilizing graph analysis models and algorithms to exploit complex interactions over a
network of entities is emerging as an attractive network analytic technology. In this paper, we …

Flash-based solid-state drives (SSDs) are getting popular to be deployed as the second-
level cache in storage systems because of the noticeable performance acceleration and …

This paper proposes a novel mechanism to model a time series of block accesses for
profiling block access patterns, to intentionally direct block data prefetching. The basic idea …

In virtualization platforms, host-side storage caches can serve virtual machines (VM) disk I/O
requests, which originally target network storage servers. When these requests hit host-side …

The flash-based SSD is used as a tiered cache between RAM and HDD. Conventional
schemes do not utilize the nonvolatile feature of SSD and cannot cache write requests …

Storage performance bottlenecks are one of the major threats limiting the scalability of I/O
intensive applications. Parallel storage systems have the potential to alleviate I/O …

In many settings, a database server has to be restarted either in response to a failure event,
or in response to an operational decision such as moving a database service from one …

Caching is an important determinant of storage system performance. Bulk cache preloading
is the process of preloading large batches of relevant data into cache, minutes or hours in …

Due to explosive increase in the amount of data produced recently, cloud storage system is
required to offer high and stable performance. However, VM (Virtual Machine) migration may …
