This work is dedicated to eliminating the overhead required for guaranteeing the storage
order in the modern IO stack. The existing block device adopts a prohibitively expensive …

Docker containers have been increasingly adopted on various computing platforms to
provide a lightweight virtualized execution environment. Compared to virtual machines, this …

A significant drawback of erasure codes is suffering from the expensive update overhead,
and all parity blocks are regenerated once any update of one data block for consistency …

Virtual Machine (VM) live storage migration is becoming increasingly important and
indispensable in the current cloud data centers, for the purposes of load balance, hardware …

This paper considers the problem of how to reduce the I/O overhead of data update
operations in erasure coding based storage systems. To this end, we first analyze the I/O …

Consumer-grade solid-state drives (SSDs) guarantee very few things upon a crash. Lacking
a strong disk-level crash guarantee forces programmers to equip applications and …

The relational database service in cloud usually achieves energy efficiency by using
virtualization technology, in which it consolidates multiple independent database systems …

Erasure coding is the leading technique to achieve resilient redundancy in cloud storage
systems. However, it introduces two prominent issues: data repair and data update …

Flash-based solid-state drives (SSD) are being widely adopted in virtualized environments
to improve the I/O performance due to their low latency and high throughput compared with …

Erasure code is widely used in storage systems since it can offer higher reliability at lower
redundancy than data replication. However, erasure coding based storage systems have to …
