Different people have different views on Cisco C3750 switches. Some people have had dreadful experiences with large number of failures and stacking problems. Other people have had none. Here is apoll to gauge how bad they are, or are not.

Inspired by Steve Jins "Top 10 Best Practices Architecting Applications for VMware Cloud" here is the list of five best practices for preparing your "existing workloads" for VMware vCloud. After all, its going to take time and money to re-architect your applications and you may want to gain some of the benefits of cloud from your existing systems.
Here is what you can do.
VirtualiseYes, your migration is going to be easier if its already a virtual machine. A V2C (Virtual to Cloud) is going to be a simpler transition that an P2C (Physical to Cloud). [..]

EVERYONE - Autosensing on ethernet works just fine, and all manufacturers recommend using autosensing. Why aren't you ! Lets look at how it works and why you should be using it.

Anyone who has installed VMware's ESXi4 hypervisor (if you haven't then get an idea of what you are missing with my article on how to setup your own ESXi4 server will be aware that the options for maintenance at the server itself are somewhat limited. [..]

Organizations are enthusiastically deploying server virtualization because of the immediate benefits it provides. As a result, deployment of server virtualization has never been higher - in spite of the economy. In fact, many organizations today have adopted "virtualize first" policies to help reduce capital (e.g., hardware, software, etc.) and operational (e.g., management) costs as well as improve underlying business processes....

The debate on Stackable vs Chassis based switches has a long and proud pedigree. Here is my addition to the debate.

From the Punching Cloud blog

Over the course of past week I was asked a couple of storage related questions in regards to VMFS volumes and LUN partitions. The topic of the questions were based on something that folks with experience, and knowledge of VMware virtualization platforms are aware about.

Companies looking to move to desktop virtualisation should be wary of what approach to take.
