Testing Network throughput between VMware ESX Hosts

web-image-f23fe804058174dd4b4eabfde4bedd8bHave you ever wanted to check your Network throughput between your ESX Hosts? or even between VM’s? Well I needed to do this, and I couldn’t find any straight forward how-to’s.

Having been pointed in the direction of a simple application called IPerf by Simon Gallagher I opted to use the Windows version. I’m not great with Linux, and as this is an open source application, documentation is a little hard to come by. So for me, this post is also to remind me how on IPerf works should i need to use it again.

10,000 People have taken The SLOG’s VCP4 Practice Exam

Who would have thought it!! I only set it up to help me revise for the VMware VCP4 Beta Exam.

3 Months later, it now has over 60 Questions (increasing all the time). I receive emails daily thanking me for helping them prepare for their VCP4 exam.  People as far away as New Zealand are being told to use my Exam’s and Study Notes by VMware instructors.

But the most amazing part was when i checked Google Analytics to see how many people are using it:


I never expected it to be soo popular. As you can see the hits per day are increasing at a steady rate, so i’m going to do my best, to keep adding more resources, to make sure you visitors have a reason to keep coming back.

My Twitter account is Suspended!!

This morning I awoke to two Emails from Twitter titled “Your account has been suspended” (Not quite sure why they felt the need to tell me twice).

Written in the Email was the following;

If you are one of my Followers you will know that earlier on this week someone/something got hold of my username/password for my Twitter account and used it to spam all of the people I follow. As soon as I found out, I changed my password and removed any Twitter apps that could have been used to gain access to my account and since then there has been no more spam.

So why have Twitter done this? I have opened up a Support Ticket with Twitter to try and find out.

Update: Just found out that Duncan over at Yellow-Bricks has also had his Twitter account Suspended.

No sooner had I opened the ticket, the ticket was showing as “Solved”. I checked my account, it was still suspended! So I have re-opened the ticket and I await to hear back.

Hardware Abstraction Layer (HAL)

Whilst reading a VMware document on using SQL inside VMware Virtual Infrastructure i realised that i wasn’t 100% sure on what the Hard Abstraction Layer ( HAL) actually is, so i decided to do some reading up, here is my take on it.

What is the Hardware Abstraction Layer or HAL?

The HAL is a part of an Operation System that talks directly to the machine’s Hardware.

The Windows OS is able to support multiple hardware platforms without having to have different OS versions for each hardware platform thanks to the HAL. During the installation of an OS the HAL is chosen depending on the hardware platform, because of this you are normally unable to remove the HDD from one PC and move it to a PC which has different hardware.

A HAL tip when you are installing VMware VM’s using  Windows Server 2003

Windows 2003 Server unlike Server 2008 doesn’t have the ability to dynamically adjust the HAL to accommodate extra vCPU’s after installation. So if you’re creating a new VM which may possibly need to have an extra vCPU added to it in the future, it is best practice to install the OS on a VM with 2 vCPU’s as this will install the SMP (Symmetric Multiprocessor) HAL rather than the UP (Uniprocessor) HAL. Once your install of 2003 server is complete you can change your VM’s vCPU’s back down to one. You now have the option to add another vCPU whenever its needed.

*If i have misunderstood what the Hardware Abstraction Layer is, please message me direct or leave a comment.
