WAN Management – Not on Your Watch

AM63512Network Operations Centers can be somber places.  I’ve seen quite a few during my last two decades in technology.  To monitor and manage a vast network is equal parts nerve racking and mind numbing boredom as you stare at wall-to-wall screens, waiting for an alarm to go off.

Over the years, networks have grown to be more and more complex because there are so many interdependent factors that affect their behavior. These factors include traffic flows, network typologies, network protocols, hardware, software, and most importantly, the interactions among them.

More frightening, the steps required to do these very complex network-wide changes are in many cases still manual.  In most enterprises this is done box-by-box one at a time – both time consuming and error prone.  On top of that you’ve got to make sure that you’ve calculated for variance with lots of different flavors of swtiches and routers in the field.  For example, to leverage a powerful feature such as Performance Routing (PfR), which can double your capacity, each WAN router must be properly configured and the overall WAN architecture adapted to the applications requirements. This can take many man-hours to implement, troubleshoot and optimize – which explains why most IT organizations spend 80-90% on operations, leaving little time for much needed innovation. Add in security, QoS, and mission critical applications and within seconds you can see this akin to kicking a sleeping beast. Once we move to the massive number of devices that are expected for the Internet of Things (IoT), then it simply becomes an unsustainable exercise in failure. Read More »

IT’s New Role in Strategic Cloud Services

As cloud-enabled services transform IT departments everywhere, your path to success as an IT professional was made easier today with Cisco’s announcement to expand its cloud portfolio. With Cisco’s comprehensive cloud portfolio offerings, you can easily and securely combine workloads to manage cloud services across different clouds.

Cisco Announces Open and Secure Hybrid Cloud with the Collaboration of Cloud Providers and Technology Partners

In my previous blog ,  I noted that IT is increasingly transitioning towards an IT service broker role, taking advantage of multiple sourcing options to become an intermediary of cloud services offered to the business constituents.  The role of IT as a broker of cloud services enables them to add value on behalf of its users by dynamically aggregating, integrating, and customizing the delivery of multi-cloud services (whether public, private or a combination of both) to best meet the needs of the business.

It’s now time for Cisco to take the next bold step in leading the evolution of the “World of Many Clouds,” journey with our partners.  Today, at Cisco Live! in Milan, we announced important news in the significant expansion of our Cloud Portfolio to enable a new Fast IT model. The new products and services in Cisco’s extended cloud portfolio include:

These solutions that we will detail in coming blogs are designed to provide major benefits for your organization as you move to the world of many clouds. They allow you to

  1. Reduce  your exposure to risk in cloud environments.
  2. Enhance your business flexibility with a choice of consumption models in the world of many clouds.
  3. Increase agility and reduce TCO by managing and automating your cloud environments

Delivering Mobile and Cloud Services Now Gets End-to-End Network Control

From the Data Center across the WAN to the User – with unique Citrix integrations for the Cisco Open Network Environment

In the long history of the Cisco and Citrix partnership, the two companies have worked together to deliver great solutions to many of the largest corporations in the world.  About 16 months ago, we enthusiastically agreed to expand the solution sets we jointly deliver beyond Desktop Virtualization to also address the Mobility, Cloud Services and Cloud Networking marketplaces.  Few other alliances in the industry can match the breadth and depth of the integrated solutions Cisco and Citrix are developing.

This week at Cisco Live in Milan, I now have yet another reason to stay excited about our partnership with Cisco… the new announcement from Cisco about Cisco ONE (Open Network Environment) Platform supporting “both” datacenter and enterprise networks.   Read More »

Top Things to Know About DFA Before Cisco Live Milan

Two weeks ago, I presented a webinar on Dynamic Fabric Automation (DFA) and went over the allocated 1 hour to cover the content.  Yesterday, as I was doing follow up with a hands-on demo, I went over time too. This illustrates how rich DFA is, and how much there is to say about it! Dynamic Fabric Automation is an environment for data center automation that is centered on the CPOM (Central Point of Management), a set of services that are provided with the new Data Center Network Manager (DCNM) release 7.0(1).

The services available on the CPOM provide the following:

  1. Power On Auto Provisioning (POAP)
  2. Inter-switch link connection verification
  3. A single console for configuration
  4. Network Auto-Config Profile provisioning
  5. Message processing for external orchestrator
  6. Automatic host provisioning
  7. Embedded management for network monitoring and data collection

All of these services are provided using standard protocols and applications. For example, the POAP service uses DHCP, TFTP and SCP/SFTP, but using a combination of templates and a very intuitive and easy-to-use GUI, DCNM provides a simplified and systematic way of bringing up your data center fabric. The inter-switch link validation or cable consistency check allows the operator to verify the fabric connections against a predefined template and prevent unexpected connections to come up.

The Jabber process provides the single console for configuration, statistics and troubleshooting. Using any XMPP client, an operator can “chat” with the fabric devices; this approach offers the possibility to organize devices in chat groups that match their role, their location or simply some administrative set. With XMPP, a single command can be sent to multiple devices in a secure way.

The most important element of the CPOM is certainly the network profile provisioning. Read More »
