Tracking down noisy neighbors

Good post by Frank Denneman (thank you)

A big part of resource management is sizing of the virtual machines. Right-sizing the virtual machines allows IT teams to optimize the resource utilization of the virtual machines. Right sizing has become a tactical tool for enterprise IT-teams to ensure maximum workload performance and efficient use of the physical infrastructure. Another big part of resource management is keeping track of resource utilization, some of these processes are a part of the daily operation tasks performed by specialized monitoring teams or the administrators themselves. Service Providers usually cannot influence the right sizing element, therefor they focus more on the monitoring part.

Deep Dive: Memory consumption of a Veeam repository

Good post by Luca Dell’Oca (thank you)

Veeam repositories, both Windows and Linux based, are running a software component responsible for receiving and storing data as they are processed by proxies. One of the most important parameter when sizing a repository is its expected memory consumption. Here are some informations for its proper configuration.

VSAN Evaluation – How to use the sizing tool – Part 1

Post by Rafael Kabesa (thank you)

Sizing a vSphere environment for VMware Virtual SAN is not an easy task and if this is how you look like when you approach it you should continue reading. Nevertheless, even if you already did sizing for VSAN in the past there are some nuances that you might want to pay attention to.

Don’t over-build your hosts for VMware VSAN

blueprint

Post by Ron Oglesby (thank you)

VMware Virtual SAN (VSAN) is a new hypervisor-converged storage technology that’s getting a lot of attention. And for good reason. It has the potential to offer incredible I/O performance at much lower price points (compared to SAN) by leveraging cheap local storage.

But like any new technology, you have to fully understand what it is and how it’s going to be applied before you start making cost assumptions and configuration recommendations.

VMware Virtual SAN Design and Sizing Guide

whitepaper_download

VMware Virtual SAN is a new hypervisor-converged, software-defined storage platform that is fully integrated with VMware vSphere®. Virtual SAN aggregates locally attached disks of hosts that are members of a vSphere cluster, to create a distributed shared storage solution. Virtual SAN enables the rapid provisioning of storage within VMware vCenterTM as part of virtual machine creation and deployment operations.

Virtual SAN is a hybrid disk system that leverages both flash-based devices, to provide optimal performance, and magnetic disks, to provide capacity and persistent data storage. This delivers enterprise performance and a resilient storage platform.

The distributed datastore of Virtual SAN is an object-store file system that leverages the vSphere Storage Policy Based Management (SPBM) framework to deliver application-centric storage services and capabilities that are centrally managed through vSphere virtual machine storage policies.

This document focuses on the definitions, sizing guidelines, and characteristics of the Virtual SAN distributed datastore.

How to get your VDI storage right

Good post by David Howell (thank you)

Many IT managers are now exploiting a virtual desktop infrastructure (VDI), in which everything on a desktop computer is moved to a host server. But they often grapple with unpredictable workloads and find it difficult guess the storage requirements for the near and long term.

It makes the deployment and management of the connected storage a critical issue in running a VDI, which by its nature requires a highly robust and flexible storage medium with low latency and fast input/output (I/O) access.
