COWCache: effective flash caching for Copy-on-Write virtual disks

Jianyu Fu, Youyou Lu, Jiwu Shu, Guangming Liu, Ming Zhao
2019 Cluster Computing  
Host-side flash caching emerges as an effective solution for improving the performance of virtual machines (VMs) in cloud computing environment.  ...  First, COWCache designs a new architecture that bridges the semantic gap between flash caching and virtual disk management for realizing the VMs' real data locality.  ...  CloudCache proposes a new cache demand model called Reuse Working Set to predict a VM's cache demand and to make cache allocation.  ...

In recent years, high interest in using Virtual Machines (VMs) in data centers and Cloud computing has significantly increased the demand for high-performance data storage systems.  ...  Unlike traditional I/O caching schemes which allocate cache size only based on reuse distance of accesses, we propose a new metric, Useful Reuse Distance (URD), which considers the request type in reuse  ...  Ramesh Sitaraman for serving as the shepherd for this paper.
