Data Center Newsletter: The Journey to Unified Computing

February 9, 2010 at 12:00 pm PST

Organizations are ready to promote greater value with virtualization, however, data center complexity and costs are skyrocketing. Virtual machines have emerged as the new “atomic unit,” moving fluidly throughout the data center, promising reduced costs and increased flexibility.

  • Hindered by decreasing budgets and accidental architectures of the past, IT managers are struggling to realize the full potential of virtualization.
  • IT leaders must navigate a complex maze; combining diverse solutions and manual processes in the quest to cost effectively refresh aging technology, adhere to industry standards, and plan a safe path to the future.
  • Strategic architecture decisions made today will largely determine an organization’s competitive position for the next economic cycle.

As a result, core assumptions about infrastructure and data center strategies are shifting radically.

The key to a more efficient, simplified, and manageable data center lies with Cisco Unified Computing. This integrated architectural approach is built upon the virtual machine as the core element, uniting virtualized compute, network, and storage resources to reduce costs and increase agility. Cisco’s innovations are designed to unify data processes, simplify data center complexity, and amplify business results.

Adding 10GBase-T Support to the Portfolio

February 8, 2010 at 12:00 pm PST

 

One of the central tenets for Data Center 3.0 is the migration from GbE to 10GbE.  Whether its to support unified fabric (FCoE or iSCSI) or to support the type of I/O consumption server virtualization is driving, we feel 10GbE is a fundamental building block of the next generation of data centers.

To that end, we have spent a good deal of effort providing our customers a granular and cost effective path from their current GbE infrastructure to 10GbE.  We support fibre based connections across our switching portfolio with a wide variety of optics.  With the advent of the Nexus 5000, we also added twin-ax to the mix with significantly lowered costs.  A little while later, we introduced the Nexus 2000 fabric extenders at yet another option for customer migrating their data centers to 10GbE that both lowered costs and simplified management.  We also recently added the Cisco Nexus 4000 blade switch for the IBM BladeCenter to the mix. The latest option we are offering is 10GBase-T (IEEE 802.3an-2006) support which allows customers to take advantage of their existing copper cabling as they navigate the transition to 10GbE.  In keeping with the extend-your-investment theme, 10GBase-T will initially be available for the Cisco Catalyst family first, then the Cisco Nexus family.

With the addition of the 10GBase-T options, we continue to offer the broadest, most flexible portfolio of 10GbE options. Here are some more details:

Bring Your Data Centers Closer with OTV

February 8, 2010 at 12:00 pm PST

 

One of the ongoing challenges for our customers is finding ways to easily interconnect their data centers.  Traditional drivers for this have been business continuance and the desire to load balance and make better use of underutilized resources.  While these continue to be important, because of the spread of server virtualization, we also see emerging drivers around supporting inter-data center workload mobility and cloud import/export of workloads.

At this point, you may be thinking “Omar, there are already ways to do this, some even offered by Cisco--some you have have blogged about!”  Yes, dear reader, its true, but with the release of a new NX-OS feature called Overlay Transport Virtualization (OTV) on our Nexus 7000, we expect to make connection your data centers simpler while at the same time, making those connections more intelligent and better suited to the emerging demands on a data center interconnect solutions.

The cool, unique thing about our OTV solution is that it works with your existing transport.  Essentially, OTV provides Ethernet LAN extension and “MAC routing” on top of the existing layer 3 (i.e. IP) infrastructure.  Here is a quick (~ 3 min) video that goes over the basics of the OTV solution.

Optimizing Delivery of Applications from the Cloud

The adoption of cloud-based computing promises to improve the agility, efficiency, and cost effectiveness of IT operations required to provision, scale, and deliver applications to the enterprise. As with other technology trends, delivering applications from the cloud, to remote sites, creates challenges with application performance, availability, and security.

Enterprise IT departments are continuing to invest in technologies that generate cost savings while making their business applications more agile and available. These initiatives, such as consolidation of branch-office servers and virtualization of data center servers, are increasingly being adopted by the enterprise; however, they have not been without consequences. For example, branch-office server consolidation projects, while reducing the server footprint, can result in a poor end-user experience and increased bandwidth utilization because applications traverse a WAN link with higher latency and packet loss and lower bandwidth than they traverse a LAN link. WAN optimization solutions, such as Cisco® Wide Area Application Services (WAAS), are implemented to deliver LAN-like application response times for end users and to defer a WAN bandwidth upgrade.

Nexus 1000V Seminar Series

February 5, 2010 at 12:00 pm PST

We have seen some incredible uptake on the Cisco Nexus 1000V as customers deploy the switch to help them scale their sever virtualization efforts.  In support of that, starting next week, we are rolling out a seminar series to help customers better understand the solution and the applicability in their own environments.  The sessions are free and are delivered by folks that are experts in their areas--OK, disclaimer, I am leading one session, but that’s as a host for a customer panel, so I think I shouldn’t screw that up too much.  There is a business track and a technical track and include topics like ROI and business impact, basic and advanced design and configuration topics, and broader architectural considerations.

Anyway, check out the complete list of sessions and and register here.  BTW, if there is a topic you’d like to see us address, let me know in the comments section.
