I was reading the post Small Business Virtualization and that really got me thinking about Small to Medium Businesses and what part Cloud Computing will play in that market. There are plenty of small businesses in and around my area and I have a couple of friends that are the owners of a couple of these small businesses. A majority of these small businesses have a single or a couple of point of sale machines that feed to the accounting program. It is these businesses that I think of when I think of what a small business is. Would virtualization help these companies? Sure, I think so but would it really be worth the cost to setup and maintain?

It has been just over two years that the Cisco Unified Computing System (UCS) was announced and released to the world. I wanted to give my feedback on the progress of the platform and how it is fitting into the Cloud Computing space.

When Cisco announced their Unified Computing Platform a couple of years ago, the thinking was not to just design and get into the server business, Cisco’s goal was to and become the heart of the datacenter itself. This was a big move by Cisco considering, that they had a very good working relationship and partnership with HP well, at least until the announcement that Cisco was getting into the server business.

vSphere Client for the iPad

The VMware Community Roundtable, which is recorded every Wednesday, has been available for download from iTunes for the last couple of years or about as long has the podcast has been presented on TalkShoe.com. Other than the community podcast and The Virtualization Security Podcast there have not really been too many other things available on iTunes for VMware technologies or products. You could find a VCP study guide, VCP Exam Cram from Pearson Education and some other third party tools to control VMware vCenter from your iPhone and/or iPad. Within the last couple of years there have been hundreds if not thousands of iPads that have been given away at the different technology conferences and the sneak peak from VMware at these conferences, on the iPad application that they are working on, it was just a matter of time and that time has come with VMware releasing the VMware View for iPad and the VMware vSphere Client for the iPad.

In my last post I was Exploring a Limitation of VMware DRS and I have encountered another situation that had similar symptoms but the resolution was quite different. This problem was occurring on a VMware ESX 3.5 cluster that was specifically affecting Windows 2008 R2 64bit virtual machines that were configured with four processors and eight gigabits of RAM. These virtual machines were taking an extreme amount of time to perform a reboot. During the reboot ESXTOP was showing insane %RDY with spikes climbing over 200. When the reboot would finally finish several services would have failed to start.

I have been a big fan of VMware’s Distributed Resource Scheduler (DRS). VMware DRS is a service or feature that will dynamically allocate and balance computing resources across the hosts in a cluster. In all of the environments I have work with so far, DRS has been a fantastic tool for getting and maintaining that balance across all the hosts in a cluster. Recently though I have come across a limitation of VMware’s DRS that is worth mentioning.

Monitoring from the Cloud

I have started the year 2011 out by looking at some of the different monitoring solutions available for us to have an insight into the health and welfare of the systems that we support. In your typical monitoring solution you would install the monitoring server in your environment and let the system discover all the devices in your infrastructure and or to control the licenses we would manually enter the devices that we want to monitor. Some of these monitoring servers solutions have to have a beefy box to begin with and all solutions will need a great deal of “tweaking” to control the number of false positives as well as time put in to be able to report on what exactly we care to be alerted about.

It is the start of 2011 and I hope everyone has not broken their New Year’s Resolutions already. To start the year off, I would like to encourage and or challenge you to become a part of your local VMware User Group or VMUG as we like to call it. Last year I did a post on My Experience with VMUGs and I am a full supporter of this program and the good it can bring. Although I have a bias for the VMUGS over other types of user groups, the concept of people helping people rates high in my book and I would like to challenge you all to get involved.
