some thoughts on storage in virtualisation November 15, 2012

Today my mind turns to storage with virtualisation.

I am currently prepping to teach a new virtualisation course and I have just reached the module which deals with storage optimisation.

In the good old days I used to be a virtualisation consultant and engineer. I used to get called out to customer sites to troubleshoot performance issues.

I always followed a specific order in analysing the issue.

1)      Storage

2)      Memory

3)      CPU

4)      Networks

My reasoning being, VMs are stored on datastores, and if we have a great number of VMs on a single LUN / datastore then we have issues.

However other factors need to be considered.

Storage protocols, generally Fibre channel and hardware iSCSI may be faster than software iSCSI and NFS, purely because processing in the software protocols may be done by the host, rather than offloaded to the storage adaptor or array.

Proper Configuration of your storage devices, goes without saying.

Load balancing across storage, generally more read / write heads and multiple paths equals better performance, just think about motorways versus single farm track.

Storage queues, I prefer to call this latency, basically how fast can we eliminate the queue, ideally I’d love a latency of 0ms.

Now obviously I can’t tell you how to configure your storage, but what I hope I’ve given you is some food for thought.

It’s time to start looking at IPv6 September 16, 2012

Posted by vbry21 in General Stuff.

We’ve been told for a few years now that the IP v4 pool of addresses was becoming dangerously depleted.

I was reading an article today that near enough says they are now gone in Europe.

On 14 September Ripe NCC got down to its last 16 million IPv4 addresses. While this might sound a lot, but it’s not and any new applicants will only get about 1000 addresses.

Immediately prior to reaching the last big block Ripe was handing out just under four million IPv4 addresses every 10 days.

So based on the maths above we’re out of addresses in 40 days.

To read the article I read, visit the link on the BBC website



New Cloud Email from Microsoft August 1, 2012

I was talking about clouds today and we got into a conversation about Hotmail and that Hotmail, we could argue is a cloud app. The argument being we are consuming a service from a provider and we don’t really care where the data is, we can also access the data from multiple devices.

However I digress, the purpose of this blog is that Hotmail is not called Hotmail anymore it is now called outlook.com

This makes sense because the corporate mail system is called Outlook, so let’s make the cloud email also called Outlook.

I logged in today and created an email address and an account and all is working well, I’ve added the account to my iPad and iPhone.

I’ve imported all my contacts from my other web based email and social media sites.

It took 5 minutes and I’ve also bagged a usable email address, all achieved because I signed up early.

The cloud was never easier.

A definitive definition of what is cloud computing July 24, 2012

Posted by vbry21 in General Stuff.
add a comment

I teach all about clouds, and I have the VMware definition and the Microsoft definition burned into my mind; however both companies differ in what they say a cloud is and what a cloud does, so I decided to get a definitive answer.

The best place to get an accurate answer is from a standards body and that is what I have done.

I decided to go with the National Institute of Standards and Technology

Happily I found they had published a document that explains a cloud definition, service models and types.

Very handy and it’s very academic.



Working Virtually or Virtually Working? July 4, 2012

Working virtually or virtually working?

The old ones are the best ones (working hard or hardly working).

My area of work centers around virtualisation and one of the areas is VDI or Virtual Desktop Infrastructure.

In a nutshell this means we take a desktop operating system and install it in a virtual machine, we store the virtual machine in the datacentre and it’s securely located in a big building with lots of redundancy for the systems, the user then accesses that virtual machine via a remote desktop protocol from virtually anywhere.


The user can access the virtual desktop from any supported device, PC, thin client, smart phone, tablet etc.

Think about 2000 physical desktops being upgraded from Windows 7 to Windows 8 located across Europe, this will take more than a couple of hours to upgrade, and then we have a fault, how about rolling them back, with VDI users connect to VMs, so all we do is point the user at a new VM, hey presto 5 minutes, maybe even quicker, the original VMs can also be kept.

Operational costs, the IT support is centralised, the VMs are centralised, they can be protected by High Availability Solutions, and the entire site can be protected. If a thin client or other device fails, simply send a new one, no software needs installed, it’s on the VM.


We’ll at some point need network connectivity; if the network dies some does the user’s ability to run their desktop. Offline mode will help, but we need to sync local to datacentre at some point.


It’s my job, I like VDI, some may hate it, and some may have different ideas.

I use VDI solutions, I have an iPad, I like the fact I can run my Windows 7 or Windows Remote Desktop Service on my device, I like the fact I can RDP onto my vCenter or VMM server and manage the virtual environment. I very rarely use my laptop now for work purposes, to be honest, I only use it now to prepare courses and write these posts. My email comes to the iPad, and that’s the advantage of virtualisation, any device, anywhere
