Virtualize Your VoIP Phone System? Yes You Can!

It’s summer and during summer, VMware Netherlands traditionally organizes the VMware Summerschool. I love to be there as you get to talk to people you normally wouldn’t meet. So, recently during the coffee break I found myself having a conversation I haven’t had for quite some time. A company still had a load of servers physically installed on the hardware and not virtualized. Both sysadmins were convinced that it was not possible to virtualize their Instant Messaging (Lync 2013) and Cisco VoIP phone system. Their communications partner advised against it and they claimed they’ve tried it in the past [ … ]

Blue Medora vRO plugin for F5 BIG-IP

Lately I am trying to follow as much as I can about orchestration and automation and recently I followed a webinar from Blue Medora. This webinar was focused on the release of their vRealize Orchestrator plugin for F5 BIG-IP. This plugin enables automation of BIG-IP tasks such as auto-scaling, application provisioning, and automatic systems maintenance and patching. The plugin will be fully supported by Blue Medora for vRealize Orchestrator versions 6 and 7, the F5 BIG-IP will need version 11.5.0+ to be supported. Out of the box the plugin delivers 50 workflows and over 1.800 scriptable actions to [ … ]

VMware NSX 6.2.3 – SSL VPN Behaviour Change

NSX 6.2.3 was released a few weeks ago and brought a bunch of new stuff and fixes. I came across an undocumented change not mentioned in the release notes, which caused me some head ache, this post describes that change. The NSX Edge Services Gateway can provide you with a SSL-VPN solution, making it possible for road-warriors to connect to the secured virtual network or make it possible for developers to connect to duplicate development environments. The SSL-VPN client is a lightweight and easy to use VPN client and you can set all kinds of policies as [ … ]

Update your knowledge at VMware’s Summerschool

It has become sort of a tradition; The VMware Summerschool at the VMware offices in Utrecht, Netherlands. Every year during the summer, VMware’s SE’s get up and in front of a whiteboard and beamer to talk about the old and the new things in VMware’s software world. The best thing is, it’s totally free! It only takes a morning of your time. This year’s program is even more extensive. The SE’s have compiled a set of sessions that includes almost every important VMware product you can think of. The VMware Technical Account Managers come out for the first time [ … ]

Removing the VMware NSX Solution from vCenter

If you want to remove VMware NSX from your vSphere environment, it’s as simple as reversing the installation steps (remove logical network configuration, remove NSX Service VMs, remove the NSX VIBs from the ESXi hosts and remove the NSX Manager). NSX is completely managed through the vSphere Web Client connecting to your vCenter. After you have reversed the installation steps, you are left with the NSX solution inside the vSphere Web Client. Removing the NSX Solution from vCenter Inside vCenter there’s the Managed Object Browser (MOB), which has access to all objects in the vCenter system and you [ … ]

VMware Fling – DRS Doctor

DRS is a very powerful vSphere feature that has been around for years. It’s constantly monitoring host performance to ensure that VM demand is satisfied. When DRS determines that another host in a cluster could better suit a VM, a migration recommendation is generated, and the VM will vMotion to another host. DRS looks at several aspects to VM performance like CPU ready time, CPU utilization, memory active and memory swapped to make intelligent placement decisions. DRS has historically been a black box though. This decision information can be ascertained by analyzing DrmDump files, but requires engineering support to decode and [ … ]

pyvmomi: Cross platform scripting for VMware

There is a lot of attention for PowerCLI for the day to day automation of your VMware infrastructure. But what if you don’t have or want Windows machines? When you are using your Mac or Linux machine for maintenance you have to create a virtual machine with Windows especially for PowerCLI. Use Python Or you could just use Python. Next to PowerCLI VMware released vSphere API bindings for various programming languages. The vSphere API Python bindings is one of them. The benefit of using Python for your VMware management is that it is cross platform. You can’t compare it to PowerCLI [ … ]

Three Dimensions of Storage Sizing & Design – Part 2: Workloads

In this second post of the multi-post Three Dimensions of Storage Sizing & Design we will dive deeper in the dimension: Use and specifically the application Workloads part. By developing an understanding of the different kind of workloads and their characteristics will enable you to look at your different workloads and determine what impact that will have on the design and sizing. Knowing, understanding and classifying which applications will run as a workload interacting with the storage, gives you an important puzzle piece. Knowing workloads Applications have been created to support us and automate processes to work [ … ]

VMware NSX 6.2.3 released

VMware NSX 6.2.3 was released today and it’s a good one! There’s a lot of improvements and some new stuff in there, it’s a hell of a maturing release. Below are a few highlights. NSX for vShield Endpoint license There’s a default license generated when you install NSX now, and it defaults on the NSX for vShield Endpoint license. This means you can by default (and without cost) manage anti-virus offloading functionality. This is one step closer to a vShield replacement and an open download. NSX Hardware Layer 2 Gateway Integration This has been in the works for a while [ … ]

Microsoft’s Convenience Update breaks VMware networking

Two days ago, Microsoft recently released a Convenience Update patch for Windows 7 and Windows Server 2008 R2 SP1. This update has incompatibility issues with virtual machines running on the VMware vSphere virtualization platform. This incompatibility is confined to one specific configuration scenario: It impacts VMs that use the VMware VMXNet3 virtual network adapter type. Please note, it involves this update by Microsoft As most of us out there use this network adapter, it can become quite an issue if you roll this out over your VM’s. Basically, they will become unresponsive at the network. On the [ … ]
