Replacing disks in vSAN could be a bit less smooth than some of the traditional Storage Arrays. For normal disks used for storage it’s quite easy, but disks used for caching it can be a slightly different story. If you get a dead caching disk you should remove it from the config before removing it physically from the server. Otherwise you will get the problems described in this posting. Once the disk has been replaced you will be unable to delete the disk or the disk group both from the…Read More
When searching for scripts that relate to VMware (PowerCLI, Perl VILib, etc), you usually end up on a blog or a forum post somewhere, probably pointing towards GitHub for an example script. VMware themselves didn’t have a proper place for example scripts, like most vendors have in their developer centers. But an announcement on the VMware Community Podcast said that they are finally coming around to it and release a beta of the new VMware Samples Exchange. The VMware Samples Exchange (SVE) is…Read More
Today’s blog post is the final entry in a series by Marcos Hernandez , one of the OpenStack specialists in VMware’s Networking & Security Business Unit (NSBU). Part 1 discussed the basics of the Neutron integration for VMware NSX. Part 2 discussed foundational integrations for L2 and L3 network services.
VMware was the first to paint a vision of the Software-Defined Datacenter as the architecture for hybrid cloud. In an SDDC all infrastructure resources and services (compute, storage and networking) are virtualized and more flexibly provisioned and managed through a policy-based, application centric approach. VMware customers have recognized the value of SDDC and are asking
There have been questions around the overhead of the VAIO framework due to its extra user-to-kernel communication. In this blog post, we evaluate the performance of vSphere APIs for I/O Filtering using a null I/O filter and demonstrate how VAIO scales with respect to the number of virtual machines and outstanding I/Os (OIOs). The null I/O filter accepts each I/O request and immediately returns it.
One question I’m commonly asked (aka weekly if not daily) is what are the perfect pCPU to vCPU ratios that I should plan for, and operate to, for maximum performance. I wanted to document my perspective for easy future reference. The answer? There is no common ratio and in fact, this line of thinking will […] The post vCPU to pCPU Ratios – Are they still relevant? appeared first on VMware vSphere Blog .
By Tristan Todd, Architect, End-User Computing, VMware In advance of the next major release of VMware App Volumes, VMware is undertaking a performance and scalability reference architecture (RA) project. This project is aimed at helping customers and partners understand the App Volumes product in a production configuration, where technical planning helps deliver consistent performance and […] The post App Volumes Performance and Scalability Testing – Preparing to Test appeared first on VMware…Read More
I can’t believe it – it’s been nearly a year since we released VMware App Volumes 2.5! We have been innovating at a rapid pace, shipping several releases throughout the year with new features such as storage groups, multi-vCenter Server support and enhancements to VHD to name a few.
By Dale Carter With the release of VMware User Environment Manager 8.7 VMware added a number of new feature, all of which you will find in the VMware User Environment Manager Release Notes. However, in this blog, I would like to call out two new features that help when deploying User Environment Manager alongside VMware […] The post User Environment Manager 8.7 working with Horizon 6.2 appeared first on VMware Consulting Blog .
By Romain Decker VMware introduced a new component with vSphere 6, the Platform Services Controller (PSC). Coupled with vCenter, the PSC provides several core services, such as Certificate Authority, License service and Single Sign-On (SSO). Multiple external PSCs can be deployed serving one (or more) service, such as vCenter Server, Site Recovery Manager or vRealize […] The post Configuring NSX-v Load Balancer for use with vSphere Platform Services Controller (PSC) 6.0 appeared first on…Read More

by Chien-Chia Chen Introduction The networking stack of vSphere is, by default, tuned to balance the tradeoffs between CPU cost and latency to provide good performance across a wide variety of applications. However, there are some cases where using a tunable provides better performance. An example is Web-farm workloads, or any circumstance where a high […] The post Dynamic Host-Wide Performance Tuning in VMware vSphere 6.0 appeared first on VMware VROOM! Blog .
