Large advances have been made in hardware and every level of the software stack since the virtualized Hadoop tests published in April 2013. This paper shows how to take advantage of these advances to achieve maximum performance. The cluster size remains at 32 two-processor 2U hosts; however, the processor, memory, network, and storage capabilities are all roughly doubled from those reported in ...

The CPU scheduler is an essential component of vSphere 5.x. All workloads running in a virtual machine must be scheduled for execution and the CPU scheduler handles this task with policies that maintain fairness, throughput, responsiveness, and scalability of CPU resources. This paper describes these policies, and this knowledge may be applied to performance troubleshooting or system tuning. Th...

This white paper provides a detailed description of the technical aspects and benefits of deploying VMware vSphere version 4 on EMC Symmetrix DMXTM or Symmetrix VMAXTM devices using Virtual ProvisioningTM. This paper also includes an overview of the latest Symmetrix Virtual Provisioning features and best practice recommendations for deploying virtual machines onto Symmetrix thin devices.

We demonstrate an enterprise Dynamic Thresholding System for data-agnostic management of monitoring flows. The dynamic thresholding based on data historical behavior enables adaptive and more accurate control of business environments compared to static thresholding. We manifest the main blocks of a complex analytical engine that is implemented in VMware vCenter Operations Manager as a principal...
