Does Converging the LAN and SAN Make Sense?

Why exactly would IT organizations want to converge their LAN and SAN?

For years, organizations have been running separate, parallel networks in their datacenter: an Ethernet-based LAN to connect servers, clients, and a storage area network (SAN) to connect servers to the storage pool. Collapsing these networks down to a single common network infrastructure could save capital costs by eliminating redundant switches, cables, networking cards, and adapters.    Customers could immediately realize cost savings by simplifying the network administration.

Organizations can achieve these benefits:

  • Efficiency.  Eliminate   infrastructure redundancy.
  • Agility. Provides the ability to set up, move, and change both physical and virtual servers faster to   easily respond to ever changing business needs.  
  • IT transformation. Enables datacenter consolidation, and supports a capacity demand model that help IT organizations do more with less.

Part 2 – London Gartner Data Center Conference, from an ancient Scottish castle to Big Ben

Big Ben in central London

Yesterday (see part 1) I started my discussion on the Gartner Data Center Conference with a picture of a castle close to my house; today I will start with what I saw as I emerged from the London Underground stop near to the conference hotel – the iconic Big Ben and the UK Houses of Parliament.

In this blog, I will discuss some of the key data center questions and feedback that I heard from some of our customers at the conference  today.  I’ve also included a short video clip which shows some of the cooler technologies and solutions on show at the conference today, not just Cisco, but some of the other exhibitors too.

So what are some of the focus areas among the technology suppliers at the show?

For Cisco, with the new Cisco Unified Management  for Data Center and Cloud, Cisco Intelligent Automation for Data Center and Cloud is the focus of our main demo today, which we are showing alongside the Cisco UCS Manager.

Migration Guides show the way to Cisco UCS

2012 is almost here and if you have a RISC/UNIX migration in the planning stages or are exploring a migration for next year I urge you to read our migration case studies.  One of my favorite case studies is Freeport-McMoRan Copper & Gold. Freeport determined the company’s existing infrastructure and ERP environment was not delivering the scalability and performance that was needed inhibiting its ability to progress its growth agenda.  Freeport’s SAP migration to Cisco UCS increased platform utilization and maximized its infrastructure investment, while simplifying ongoing management and operational support for their ERP environment.

A migration of mission-critical applications is a decision that most organizations consider carefully. A key discussion in any RISC/UNIX migration includes an investigation of the applications and how to migrate them from their current architecture to Cisco UCS.  The typical questions are:  How do I migrate?  What are the options? Do you have any real world examples? If so, what were the results and benefits?

As part of our RISC/UNIX Migration Program, we have released a set of migration guides for key applications, such as Oracle RAC, SAP, PeopleSoft, and Siebel that answer those specific questions.  I urge you to read how Cisco customers and Cisco IT, utilizing a planned and phased approach,  migrated Oracle,  SAP,  PeopleSoft,  and Siebel applications to Cisco UCS.            Read More »

Packet Pushers Podcast on Scalable Cloud Networks with VXLAN

Podcast Greg Ferro and Ethan Banks from have released another in-depth podcast, this time on how to create scalable cloud networks with VXLAN. VXLAN, if you recall, is a multi-vendor effort to increase the number of logical networks that can be created within a cloud environment, and overcomes the challenges of using VLANs when separate tenants and application instances all need their own logical domains.

From an Ancient Scottish Castle to the Gartner Data Center Conference in London

OK, so what has an ancient Scottish castle got to do with the Gartner Data Center Conference in London?  This doesn’t sound like what I usually blog about!

Bothwell Castle, Scotland
