In my previous post I explained how SVMotion saved the day, this blog post is about the need for storage fabric redundancy. Storage fabric/network redundancy makes simple upgrades work without the need to power off any VMs or virtualization hosts. My recent upgrade to a Brocade 240E went smoothly once I could access the device. Continue reading ‘VMware ESX, upgrade to 4GB Switch – Redundancy is what it is about!’ »

The last major modification to my datacenter occured on friday. I physically relocated my SAN and its UPS. I have been reducing the size of my datacenter, as I documented in VMotion – Redundant Power Supplies Aid in Migration, and started to document in Upgrading My SAN. I was waiting on this move until the new, much shorter, fibre cables arrived. Which they did earlier in the week.
So you want to run VMware ESX or ESXi within VMware Workstation but you do not know if your laptop or desktop will support the functionality? It will work but if you do not have the proper hardware, it will run extremely slow, ie. take several hours to boot a VM. So you will need to run a few tests to determine if you have the proper hardware. However, first a few ground rules:

I have had several Blue Gears blog sites and now have just this one. I have guest blogged at both ITworld and Cisco Subnet at NetworkWorld. While I would very much like to continue blogging at those locations, maintaining several blogs at the level required is a bit daunting, so I have centralized Blue Gears into just one blog moving forward.
I do not, at this time, plan on moving any of the content from these sites. However, any new material, will be posted to this centralized location and maintained within the Blog Roll Up within the Virtualization Wiki which is a companion to the Blue Gears blog.
Virtualization is all about redundancy. Redundant network switches, frabric switches, power supplies, and of course redundant hosts. Recently, I had to reorganize my entire data center. I was removing equipment and moving equipment. I was trying to reduce everything to either a single rack or a pair of half height racks to save on space, power, and cooling.

Blue Gears will be my place for posting reviews of books, blogs, and other articles in the realm of virtualization, secure coding, forensics, and other topics. This is my home for things that do not fit the requirements of my other blogs: either too long, unrelated topic, or too technical.
Thanks to Jason Boche (http://boche.net/blog) for sending me his WordPress plugins as well as blogsecurity.net for showing me how to hopefully secure my blog.
Welcome to Blue Gears, enjoy reading.
