Improving Linux Block I/O for Enterprise Workloads
"... The block I/O subsystem of the Linux kernel is one of the critical components affecting the performance of server workloads. Servers typ-ically scale their I/O bandwidth by increasing the number of attached disks and controllers. Hence, the scalability of the block I/O layer is also an important con ..."

concern. In this paper, we examine the performance of the 2.4 Linux kernel’s block I/O subsystem on enterprise workloads. We identify some of the major bottlenecks in the block layer and propose kernel modifications to alleviate these problems in the context of the 2.4 kernel. The performance impact
Simulating complex enterprise workloads using utilization traces
- In Proceedings of the Workshop on Computer Architecture Evaluation using Commercial Workloads (CAECW
, 2007
"... Simulating enterprise environments poses several challenges by virtue of the complex nature of enterprise applications and the systems that need to be modeled. In this paper, we propose an alternate approach to simulating such environments that uses resource utilization traces from real deployments ..."

Cloud Computing and Emerging IT Platforms: Vision, Hype, and Reality for Delivering Computing as the 5th Utility
, 2008
"... With the significant advances in Information and Communications Technology (ICT) over the last half century, there is an increasingly perceived vision that computing will one day be the 5th utility (after water, electricity, gas, and telephony). This computing utility, like all other four existing u ..."

Furthermore, we highlight the difference between High Performance Computing (HPC) workload and Internet-based services workload. We also describe a meta
Workload analysis and demand prediction of enterprise data center applications
, 2007
"... Abstract — Advances in virtualization technology are enabling the creation of resource pools of servers that permit multiple application workloads to share each server in the pool. Understanding the nature of enterprise workloads is crucial to properly designing and provisioning current and future s ..."

HadoopDB: An Architectural Hybrid of MapReduce and DBMS Technologies for Analytical Workloads
"... The production environment for analytical data management applications is rapidly changing. Many enterprises are shifting away from deploying their analytical databases on high-end proprietary machines, and moving towards cheaper, lower-end, commodity hardware, typically arranged in a shared-nothing ..."

Write Off-Loading: Practical Power Management for Enterprise Storage
"... In enterprise data centers power usage is a problem impacting server density and the total cost of ownership. Storage uses a significant fraction of the power budget and there are no widely deployed power-saving solutions for enterprise storage systems. The traditional view is that enterprise worklo ..."

workloads make spinning disks down ineffective because idle periods are too short. We analyzed block-level traces from 36 volumes in an enterprise data center for one week and concluded that significant idle periods exist, and that they can be further increased by modifying the read/write patterns using
Flash-Conscious Cache Population for Enterprise Database Workloads
