VMware Product Updates – April 2013

VMware has released updates to several products over the past couple weeks.  Many of the updates take the version 5.1 products announced at VMworld 2012 to Update 1 (i.e. the first major service pack).  The updates, spanning vSphere (ESXi and vCenter), vCloud Director, vCenter Operations, vCenter Orchestrator, vCenter Site Recovery Manager (SRM), vSphere Data Protection, and the vSphere Storage Appliance, include bug fixes, security fixes, and functionality changes.  Here’s what you need to know about the updates, including a few upgrade bugs that you need to know about before you pull the … [Read more...]

Configuring VMware VASA for EMC VNX

vSphere Storage APIs for Storage Awareness (VASA) are one of several VMware vSphere Storage APIs.  VASA, new in vSphere 5.0, provides vCenter with a way of interrogating storage array LUNs and associated datastores to gain visibility into the underlying hardware and configuration of the storage layer.  Storage capabilities, such as RAID level, thin or thick LUN provisioning, replication state, caching mechanisms, and auto-tiering are presented through VASA to vCenter (a unidirectional read operation by vCenter against the array).  With VASA, vCenter can identify which datastores possess … [Read more...]

CPU Ready Revisted – Quick Reference Charts

I've written in the past about how high CPU Ready values can cause performance problems in VMware vSphere environments.  For those who don't know, CPU Ready is a measure of the amount of time that a guest VM is ready to run, but the VMware ESXi CPU Scheduler on the host is not able to immediately allocate cycles to the guest because it is busy doing work for other VM's.  CPU Ready values are exposed through ESXTOP and in the vSphere Client. I'm often called into customer environments to do performance troubleshooting, and CPU Ready is one of the first performance measurements I check my … [Read more...]

Storage Basics – Part IX: Alternate IOPS Formula

It's been a long time since I published an article in my Storage Basics series - the series has been some of the top content on my site to date.  I sat for a beta version of the VMware Certified Advanced Professional - Desktop Design (VCAP-DTD) test today and was reminded by the test of a post I had in waiting about an alternate way to calculate IOPS (hint hint - memorize these formulas).  I have several more articles sitting in draft form, but a new job, crazy kids, home improvement projects, and a wife with chronic cerebral spinal fluid (CSF) leaks (it sounds bad - and it is - but look on … [Read more...]

VMware View 5.1.x Now Compatible with vSphere 5.1!

I wrote an article a couple of weeks ago about the incompatibility of VMware View 5.1 and vSphere 5.1, but mentioned a forthcoming patch based on an update to VMware knowledge base article 2035268 (http://kb.vmware.com/kb/2035268) that I saw through a RSS subscription to the article.  Good news as of last night - that patch is now available for download, making vSphere 5.1 compatible with View 5.1.  I am a bit surprised that the patch, ESXi510-201210401-BG, applies to ESXi 5.1 instead of View 5.1.  I would expect that the older View 5.1 (released in May 2012) would need to be patched to work … [Read more...]

VMware View 5.1 Not Compatible with vSphere 5.1

Update: 10/26/2012 - a patch has been released to correct compatibility between View 5.1 and vSphere ESXi 5.1.  See here for more: http://vmtoday.com/2012/10/vmware-view-5-1-x-now-compatible-with-vsphere-5-1/ VMware released vSphere 5.1 shortly after VMworld 2012.  The new release of vSphere includes features that will be of great benefit to VMware View virtual desktop infrastructures such as the new Space Efficient virtual disk (.vmdk) format and a new virtual machine format (hardware version 9) that enhances virtual shared graphics acceleration.  However, the current version of VMware … [Read more...]

VMworld Europe News and Announcements

I wanted to let you all know about some announcements that have come out at VMworld Europe over the past couple days.  These announcements help round out some of the new products and features announced at VMworld 2012 in San Francisco.  These new and updated features are a big deal for customers who want to take a wholistic approach to deploying and managing a hybrid cloud across different service providers.  If you're thinking about upgrading your vSphere license to a vCloud Suite license (you have until December 15th to claim the free upgrade to the vCloud Suite Standard Edition, along with … [Read more...]
