VMware vCenter Update Manager 5.0 Performance and Best Practices

posted

VMware vCenter Update Manager (also known as VUM) provides a patch management framework for VMware vSphere. IT administrators can use it to patch and upgrade ESX/ESXi hosts, upgrade VMware Tools and virtual hardware for virtual machines, as well as upgrade virtual appliances. A white paper that examines the performance of VUM is available. This paper Read more...

Host Power Management in vSphere 5

posted

Host power management (HPM) on ESXi 5.0 saves energy by placing certain parts of a computer system or device into a reduced power state when the system or device is inactive or does not need to run at maximum speed. This feature can be used in conjunction with distributed power management (DPM), which redistributes VMs Read more...

VMware View PCoIP & Build-to-lossless

posted

We have talked in previous posts about the ability in View 5 to disable build to lossless (BTL). When BTL is disabled, PCoIP rapidly builds the client image to a high quality, but lossy image — by default, if the image remains constant, PCoIP would continue to refine the image in the background until it Read more...

Zimbra Collaboration Server Performance on vSphere 5

posted

Zimbra Collaboration Server is VMware’s mail, calendaring, and collaboration software. A performance study looks at how the mail server performs on vSphere 5. Test results demonstrate the following: Due to optimizations made within Zimbra Collaboration Server and the tickless timer within Red Hat Enterprise Linux (RHEL) 6, Zimbra Collaboration Server in a virtual machine can Read more...

View 5 PCoIP Client-Side Image Caching

posted

At the recent VMworld we mentioned that VMware View 5 introduces PCoIP support for client-side image caching. In our VMworld presentation, we highlighted that, on average, this caching optimization reduces bandwidth consumption by about 30%. However, there are a number of important scenarios where the ability of the PCoIP image cache to capture spatial, as Read more...

Microsoft Exchange Server 2010 Performance on vSphere 5

posted

A white paper has been published that examines how Microsoft Exchange Server 2010 performs on vSphere 5 in terms of scaling up (adding more virtual CPUs) and scaling out (adding more VMs).  Having the choice to scale up or out while maintaining a positive user experience gives IT more flexibility to right-size system deployments and Read more...

Slides from our recent VMworld presentation on View 5 PCoIP performance (EUC1987) are now available here. In addition to discusing the latest PCoIP optimizations and best practices in detail, it also presents competitive data. Read more...

Understanding Memory Resource Management in vSphere 5

posted

Memory resource management is a key player in the ability of vSphere systems to over-commit resources and thereby maximize the utilization of an ESXi host. Over-commitment allows the active memory of a system to perform as close to 100% as possible. vSphere achieves this by using several innovative techniques to reclaim virtual machine memory, which Read more...

vMotion Architecture, Performance, and Best Practices in VMware vSphere 5

posted

VMware vSphere vMotion enables the live migration of virtual machines from one VMware vSphere 5 host to another, with no perceivable impact to the end user. vMotion brings invaluable benefits to administrators—it enables load balancing, helps prevent server downtime, and provides flexibility for troubleshooting. vMotion in vSphere 5 incorporates a number of performance enhancements which allow Read more...
