By Sudhir Balasubramanian (Senior Solutions Architect – Data Platforms) and Mohan Potheri (Senior Solutions Architect) In the first part of this series we provided a high level view of the benefits of using Virtual Volumes enabled storage for database operations. In the second part of this series we examined in more detail how Virtual Volumes The post Crash Consistent Backups and Database Cloning with Virtual Volumes appeared first on Virtual Blocks.
At the VMworld Europe party on Wednesday October 14 UK bandFaithless will perform. The performance starts at 20:00.

To keep vSphere installs secure, it is often necessaryto patch or upgrade them in a specific order, as outlined in KB 2109760, which has been our guide for the last few parts of our upgrade saga.However, patching vCenter 6.0 vCSA is not as easy as it looks.The instructions in the online manuals are only apropos … Continue reading vSphere Upgrade Saga: Upgrading to vSphere 6.0 U1 → The post vSphere Upgrade Saga: Upgrading to vSphere 6.0 U1 appeared first on AstroArch Consulting, Inc.
While I’m a big proponent of using an enterprise-class certificate authority—either based on internal offline root/online issuing or public CAs—there are some instances when using a self-signed cert fits the bill. Unfortunately, most of the tools for creating a self-signed cert have defaults that result in less-than-stellar results: the digest algorithm is sha1, the cert is likely to have a 1024-bit key, and the extensions that define the cert for server and/or client authentication are…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 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 .
