Unified Computing: Collective Group or Single Responsibility

I have spent a great deal of time lately working with the Cisco Unified Computing System (UCS). This computing platform is really quite impressive with its power and flexibility, but my expectations about the platform have really changed since I completed the UCS training. During the training classes that I attended, both the design and install courses emphasized that the Cisco UCS platform would be a collaborative platform that would bring the different groups like Storage, Network, and Server each working their own functional area of responsibility within UCS based on role permissions. That sounded great. The network team can create and trunk the VLANS and the storage team could add the boot targets as well as assign the LUNS. This platform is a true collective effort by all teams right?

Defense in Depth: Firewalls within the Virtual Environment

While we covered Encryption on the 5/31 podcast, in the 6/14 podcast we covered other measures when dealing with storage (which will be part of a followup post). This conversation was slightly different than all other firewall discussions, as it was about migrating from a physical environment to a virtual environment, and keeping the same firewall placements. Spurred by a customer, we sought to come to a set of guidelines to follow for defense in depth within the virtual as well as physical and hybrid cloud environments.
