vSphere Auto Deploy

The Auto Deploy is one of the underestimated vSphere features. I have seen many vSphere Designs where using Auto Deploy was outlined as overcomplicating and manual build of ESXi servers was preferred. That is pretty frustrating as we, as IT professionals, strive to automate as much as possible in our day to day work.

vSphere Replication traffic isolation

vSphere Replication has proved to be a great bonus to any paid vSphere license. It is an amazing and simple tool that provides cheap and semi-automated Disaster Recovery solution. Another great use case for vSphere Replication is migration of virtual machines.

VMware’s EVO:RAIL fail as a lesson for Microsoft’s Azure Stack

As we know, VMware’s first attempt in the field of hyperconvergence, the EVO:RAIL, was a good quality software product set, which nevertheless failed because of the licensing policy. Specifically, it demanded that buyers acquire new vSphere licences, with no exception for existing vSphere users who liked the idea of adopting hyperconverged infrastructure.

Comparing vSphere Distributed Switch and Cisco Nexus 1000v switch

When time comes to deciding whether to go with vSphere Distributed Switch or Cisco Nexus 1000v it is hard to tell which product is superior and you find many different and quite contradictory opinions. While quite often it is the political decision based on the answer to the question “Who is going to manage the virtual networking?” there are many other aspects you, as an infrastructure designer, should be aware of.

VMware Photon OS + Docker Volume Driver = containers architecture on vSphere virtualization platform

Many of you know that VMware has a technology called vSphere Integrated Containers (VIC). It involves launch of Docker (and others) virtualized containers in small virtual machines with a lightweight operating system based on Linux distribution. This operating system is VMware Photon OS 1.0, which has been finally released just recently. This is the first release version of this operating system from VMware, but in the long view it can become the main platform for virtual appliances by replacing the everlasting SUSE Linux.

How Transparent Page Sharing memory deduplication technology works in VMware vSphere 6.0

You may know that memory page deduplication technology Transparent Page Sharing (TPS) becomes useless with large memory pages (it’s even disabled in the latest versions of VMware vSphere). However, this doesn’t mean that TPS goes into the trash bin, because when lacking resources on the host-server, ESXi may break large pages into small ones and deduplicate them afterwards. In the process, the large pages are prepared for deduplication beforehand: in case the memory workload grows up to a certain limit the large pages a broken into small ones and then, when the workload peaks, forced deduplication cycle is activated.

Evaluation of Performance and Snapshot Consolidation Process Time in VMware vSphere

Snapshots in VMware vSphere often cause various problems with configurations and performance, unless they are properly used – for live backup of virtual machines and temporary keeping VM configuration before the update. However, using them in large infrastructures is unavoidable. At some point you may need to delete/consolidate virtual machine snapshots (Delete All button in Snapshot Manager), which is quite time-consuming and demanding in terms of storage performance. Thus it would be a good thing to know in advance how much time it takes.
