Well I am still making progress with my analog alarm/monitor box, but really still need to come up with a better name for it! If anyone has any suggestions, please shoot!
I just finished the board design (I hope it is correct) and ordered a few boards, I should have them just after valentines. All the other components I already have in stock, so I should hopefully be able to offer a few kits for any of you that would like to have one of these yourself.
The software development is also going steady. I finished last weekend the configuration software (webbased), fully based on ajax. You can setup for each meter what object you want to meter (VM, Host, ResourcePool, Cluster, Datacenter) and then select any of the available counters for that object. A few are percentage based, so the meter can display 0% to 100%, but you can also have absolute numbers displayed, as you can define in the config software the min and max value.
I guess before I receive the circuit boards I really need to finish the casing, as I have not done much work on that. Hopefully can make some progress on that coming weekend. My current prototype just have a faceplate. In the end I will design 2 versions; A 4 meter version and a 6 meter version.
To be continued….
While I am playing on making cheap, cool hardware gadgets for VMware, others are focused on finding the best possible hardware to run your ESXi (or other hypervisor) on. Alex from the UK has made some real awesome progress on this in the past few days. Using a newly released Intel NUC, which is a new barebone system for 260 EUROS (inc VAT) ex memory, but capable of max 16GB he found a way to run ESXi v5 on it. Not only is this a good enough system for home lab; 16gb RAM, 2x Intel I3 Cores, 1x 1GB LAN, and the option to add extra via mini-PCI-express cards (~43 euros) it is also Quiet!!! (like in silence), which probably for most home labs will be awesome. My servers have to be in my garage (out side of the house) due to their noise. O and from the energy conscious geeks, it also just uses a few Watts
The total system with 1nic and 16GB ram comes down to 348 euro! (inc VAT). This put having 2 physical lab nodes into the possibilities of many virtual geeks out there… and without pissing of their girl friends /wifes (at least noise wise).
Read here the full article by Alex how he got everything up and running.
Is this a new trend? I hope so! I have been working on my analog hardware monitoring box for vSphere environments the last couple of weeks. This weekend I hope to finish writing my software so I can finally release a full working version. But I am not the only one experimenting with Arduino’s and Raspberry PIs to engage them with your vSphere servers and other datacenter components. Bouke, a training consultant (also Dutch), has also played with the Raspberry PI and interfaced it with vSphere. In his case he is using pyton, where I am using PHP. He just released a video showcasing his 16 LED micro monitoring box. One of his customers has a big 16 VMware vCenter large environment. So each LED represents the status of a vCenter server. It is not just pinging the servers, but really using the API to check that vCenter is running.

Let the REVOLUTION of Micro Hardware Gadgets start
Today the VRC Team released a new report in a long list of reports regarding Desktop Virtualization. This report goes into detail about how Anti Virus solutions impact you performance for VDI environments. It does not only investigate the traditional methods of doing anti-virus, but also looks at the various offloading (via network and via vSphere vShield API) methods.
Interesting to see is that the vShield offloading method does improve well on Disk i/o, but CPU is not being reduced.
The most important thing is that the document does not just describe the perfomance result with the default behaviour of the most common anti virus solutions, but discusses what kind of optimisations can be made and what their impact are. So a very useful document for anyone running or building a VDI environment.
