The Unified Network Services (UNS) portfolio of Layer 4-7 services (such as ACE and WAAS) also includes Cisco’s data center security solutions. A critical part of that security portfolio is our virtualization-aware firewall solution, Virtual Security Gateway (VSG). In a series of upcoming blog posts, I’ll be sharing a few use case scenarios that our customers are implementing with VSG.
For those of you new to VSG, I’ll point out that VSG’s role is to act as a virtual firewall between zones of virtual machines. Isolating traffic between VM zones has been very challenging prior to VSG because: 1) security policies have to be enforced between VMs running on the same server or same virtual switch (where there’s no place to put a firewall), 2) VMs move all around the network and the security policies (as enforced in the firewall) must follow the VM, and 3) the need to maintain segregation of duties for compliance purposes between the security and application server teams, where security is potentially enforced inside the virtual server.
Visit Cisco Live Virtual on Wednesday, May 25th at 10am Pacific to view the live Techwise TV Workshop “The Power of Innovative Architecture: The Ethernet Service Plus 6500 Line Card”. Join Cisco’s TechWiseTV Chief Geek Jimmy Ray Purser as he hosts Cisco Engineer Amit Singh in a deep dive on the brand new ES+ line card. They will examine the design and troubleshooting benefits this ground breaking architecture gives to Data Center, Enterprise and Service Provider engineers, with flexibility for future service deployments and scaling system capacity. Experts will be available for live Q&A.
Access is free. Attendees to Cisco Live Virtual can access over one thousand keynotes, super sessions and technical sessions, as well as network with peers, visit our Partner Resource Center and play games and win prizes.

Happy Friday the 13th! Hope no one is superstitious! Cisco’s top stories of the week include a feature on the greening of data centers, a video on the value proposition for Cisco partners and the single-purpose network; the myth of the good-enough network was also outlined. Cisco and Xerox also announced a strategic alliance to deliver cloud services.
Government and industry are pushing to develop metrics that will state definitively whether a data center is energy efficient or not. Ideally, they would like to get some generally-accepted measures, equivalent to the auto industry’s miles-per-gallon standards, that make it clear how efficiently a particular data center uses energy.

What is “in-memory”? “In memory” is a technology that takes Data Warehousing and Business Intelligence to a different level. CIO’s want information at their fingertips. In order to obtain that information, they engage in data modeling and “what if” scenarios, the answers of which give them a competitive edge in business. The biggest concern to-date, is that the data modeling and “what if” scenarios usually take days to process. SAP HANA in-memory technology allows CIO’s to obtain answers to these complex issues in microseconds instead of the typical wait of days.
Who are the only server platform vendors certified to sell SAP HANA?
What are the benefits to users of SAP HANA?
Processes all transactions in memory instead of I/O to disk
Processes millions of lines of data in microseconds
All processing done outside of normal data processing
Reduction of hardware and maintenance costs since SAP HANA is self contained in one appliance
So is SAP HANA “in Memory” technology disruptive? Absolutely. Watch Rajiv Thomas’s Video Cisco and SAP HANA about HANA
