vSphere Distributed Switching

February 26th, 2014 by Damian
Respond

Standard vSwitches can definitely get the job done, having all the features needed to implement your virtual network. The only drawback being that they are managed on a per host basis. This means you’ll need vSwitches for each and every host, and managing more than a few vSwitches in a decentralized fashion can be time-consuming. That’s where Distributed switches come into play.

vSphere Standard Switching – Part 2

February 20th, 2014 by Damian
Respond

VLANs let you tag different ports on a switch as belonging to different subnets, so that you can effectively have multiple subnets existing in a single switch. vSphere allows you to set up this functionality with their vSwitches just like you could with real switches from Cisco or whomever. What’s the reason behind wanting multiple subnets in one switch? Tailored, more efficient segmentation, security, broadcast control, etc.. It’s useful if you have port groups in your vSwitch that require access to more than one subnet. [Read more →]

vSphere Standard Switching

February 19th, 2014 by Damian
Respond

A standard vSphere switch, or vSwitch, is where networking in vSphere begins, any kind of communication taking place in your environment will require one. A vSwitch is created via the vSphere Web Client or the esxcli command. There are many similarities between real switches and virtual ones, but the most important difference is that virtual switches cannot be linked together. Consequently, they do not need or use any sort of routing protocol, such as STP. [Read more →]

vSphere Networking Basics

February 13th, 2014 by Damian
Respond

There’s a great deal of resemblance between how networking is implemented in the real, physical world and how it’s done in the virtual (vSphere) world. Most of what you know there as far subnets and the hardware used to manage those subnets are concerned also applies to virtual networking. But there are some differences and going over some terms and how they apply specifically to virtual networking is essential. [Read more →]

Using VUM

February 5th, 2014 by Damian
Respond

Baselines and Groups
There are a few moving pieces to VUM but I’d say that baselines are the main piece that is most responsible for effecting all the required updates. Baselines bring together all the updates that your hosts and VMs need to have, and are used as a measuring stick to see what changes need to be made. There a several different kinds of baselines that you can put together to accomplish whichever strategy you’re aiming for, and there are some default ones that you can also rely on. [Read more →]

PXE Booting for A Dell XPS12

February 5th, 2014 by Damian
Respond

USB21000S2_th
The Dell XPS12 has become a very popular little laptop here among my clients, its pretty much the only laptop I’ve seen them purchasing for the last few months. It is Windows 8.1 and exclusively wireless. That can be a bit of a pain for imaging and deployment as the wireless connection doesn’t support any way to PXE boot to an imaging server. There is one way around that limitation though.

You’ll need to spend a bit of cash on a USB Ethernet adapter that supports PXE booting. Not all do, you need to find one that has the right chipset and this one from StarTech does:
