VMware VSAN reusing SSD disks

#VMware VSAN reusing SSD disks

VMware VSAN reusing SSD disks

Ealier this week I’ve been configuring a new VSAN cluster. The old configuration was using hardware that wasn’t complying with the VMware vSAN HCL. We ordered new raid controllers and HDD’s and reused the SSD disks, as those where compliant with the HCL. Adding and configuring the new hardware went well and ESXi was installed without a problem. After doing some network configurations on the hosts it was time to turn on VSAN. And that is where I ran into an issue. The moment I turned on VSAN (manual mode) each host created a disk group containing the SSD’s present in the host. Each disk group however was showing only absent HDD’s. Seeing as I was using SSD’s from a previous configuration I wasn’t that suprised and tried removing the disk…Read More

If you forgot to uninstall #VMware Data Security during your NSX upgrade, not all is lost!

Removing VMware Data Security after vShield to…

An existing vShield environment can be upgraded to a full NSX environment, as described in my VCIX post “Upgrade VMware NSX Components”. All vShield components can be upgraded, except for one; vShield Data Security. The documentation states: NSX Data Security does not support a direct upgrade. You must uninstall the current Data Security software before upgrading to NSX Manager. After NSX Manager is upgraded, you can install NSX Data Security version 6.0. If you upgraded to NSX Manager without uninstalling Data Security, you must do so using a REST call. A few days ago, someone came to me with an environment where this exact thing happened. They had upgraded to NSX for all its goodness, but had not removed Data Security and could not…Read More

Cody’s article on UNMAP changes for vSphere 6 got me thinking about how this plays out in the VDI context.I’ll explore a bit desktops deployed both as linked clones with and without se-sparse disks as well as full desktops with thin provisioned disks. Before we get started I’m first goingto turn on the advanced option […] The post UNMAP Observations w/Horizon Desktops appeared first on JediMT.

What is VMware NSX?

Learn what #VMware NSX is and what it does

What is VMware NSX?

VMware NSX is the network virtualization and security platform that emerged from VMware after they acquired Nicira in 2012. This acquisition launched VMware into the software-defined networking (SDN) and network functions virtualization (NFV) world. The solution de-couples the network functions from the physical devices, in a way that is analogous to de-coupling virtual servers (VMs) from physical servers. In order to de-couple the new virtual network from the traditional physical network, NSX natively re-creates the traditional network constructs in virtual space — these constructs include ports, switches, routers, firewalls, etc. In the past, everyone knew what these things were. It was possible to see and touch the switch port…Read More
