We analyze workload traces from production data centers and focus on their VM usage
patterns of CPU, memory, disk, and network bandwidth. Burstiness is a clear characteristic of …

Effectively leveraging Flash resources has emerged as a highly important problem in
enterprise storage systems. One of the popular techniques today is to use Flash as a …

Serving as cache disks, flash-based solid-state drives (SSDs) can significantly boost the
performance of read-intensive applications. However, frequent data updating, the necessary …

Computing technology are undergoing evolutionary changes in platform and environment.
Computing becomes more and more data-intensive. The design of the data center storage of …

In this thesis, we present our works on resource management in large scale systems,
especially for enterprise cluster and storage systems. Large-scale cluster systems become …

With an increase in the capacity of storage servers, storage caches have became necessity
for better performance. For such storage caches, flash based disks have proved to be one of …

Existing caching strategies, in the storage domain, though well suited to exploit short range
spatio-temporal patterns, are unable to leverage long-range motifs for improving hitrates …

Indirection is a core technique in computer systems that offers many benefits. However, it is
easy to overlook its costs. As software and hardware systems become more complex …
