You want micro-segmentation? vRealize Network Insight is your friend!

As many of you have probably heard, in June 2016 VMware acquired Arkin Net. Arkin Net offers 360 degree visibility, enables faster deployments via micro-segmentation planning, and delivers significantly lower time to resources, leveraging constructs like ‘time machine’, natural language search, and contextual analytics. Now 2 months later the impact and position is visible, VMware will be incorporating Arkin Net with its vRealize Cloud Management platform. Under its new name, vRealize Network Insight, VMware vRealize Suite will have the ability to extend across the entire SDDC, including the VMware NSX network virtualization layer. vRealize Network Insight vRealize Network Insight has three [ … ]

Please stop stretching your VLANs, virtualize your network

Network admins hate stretching VLANs across data centers, we absolutely hate it. It causes potential instability on a inter-data center scope, destroys our isolated fault domains; something happens with VLAN X on site A, it also can take down site B (unless you take special precautions). I spent a few hours last week and the week before to help out customers that had that exact issue, which triggered this post. The entire idea of stretching VLANs between data centers is about virtual machine mobility. You can do a failover between sites and don’t have to make adjustments to your applications [ … ]

Three Dimensions of Storage Sizing & Design – Part 3: Speed

In this third 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 characteristic Speed. Depending on the application workload requirements, you will need to size the storage system for The Need for Speed. So let us dive deeper into IOPS. Speed with computer storage devices like hard disk drives (HDD), Solid State Drives (SSD) and Storage Area Networks (SAN) is expressed in Input/Output Per Second (IOPS). Applications will interact with storage for retrieving and storing data. What [ … ]

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 [ … ]
