Stay ahead of the curve with Virtual Application Networks: HP delivers SDN elements

By Kash Shaikh, Director of Product Marketing & Technical Marketing Engineering


ks.jpgToday, I’ll  share some details with you on a breakthrough announcement we are making with two new software innovations for our data center switching portfolio as a part of our Virtual Application Networks vision and strategy announced earlier this year (as discussed in the A clean sheet approach: Virtual App Networks – HP & F5 mark the beginning of the end of CLI blog post). Virtual Application Networks is HP’s Software-Defined Networking (SDN) strategy.


These innovations showcase how you can build a large logical data center while delivering on multitenancy requirement for private clouds and virtualized enterprise data centers:


1)       The HP Ethernet Virtual Interconnect (EVI), a new HP Virtual Application Networks software innovation, enables your IT staff to simplify the interconnectivity of up to eight geographically dispersed data centers. As a result, you can increase agility by connecting data centers in minutes vs. months, while  also improving workload mobility, business continuity and disaster recovery for geographically dispersed data centers. This also allows you to deliver on follow-the-sun workload mobility and cloud bursting implementations.




2)       HP Multitenant Device Context (MDC) software HP MDC partitions a single physical switch into multiple logical devices that are each allocated its own resources and configurations with complete isolation as if they are completely separate switches, enabling single cloud network to support multiple enterprise departments.




Today, with legacy networks it typically takes months of manual configuration tasks and redesign of networks to connect data centers in order to achieve increase agility for disaster recovery or business continuity. When secure multitenancy is required in enterprise data center, a dedicated switch per tenant is needed.






Now, with HP EVI and HP MDC, you can interconnect up to eight geographically disperse data centers within minutes and deliver multiple, secure and isolated tenants on a single physical switch.




The end result? Reduced cost, fewer errors and less complexity with greater performance, security and agility – letting your workloads and data move whenever you need it, wherever you need it.


Connect your data centers in minutes


The new HP Ethernet Virtual Interconnect (EVI) is the industry’s only Data Center Interconnect (DCI) overlay technology to provide “single touch” connection of up to eight data centers around the world from one location. You can optimize server and storage resources by linking the HP EVI software built into the networking switch between data centers to move virtual machines, such as Microsoft Exchange or Instant Messaging workloads, from one data center to another in case of a natural disaster or new market opportunity.


Compared to legacy DCI solutions, HP EVI can be deployed over any network including Internet, private IP network or multiprotocol label switching (MPLS) in minutes with five simple steps per data center location.


You can also connect a new data center to their existing set of HP EVI data centers with a few simple configuration steps to automatically synchronize all sites.


Additional HP EVI benefits include:


  • Reduced manual command line interfaces (CLI) configuration from hundreds of steps to five
  • Simplified single-touch DCI management with HP Intelligent Management Center (IMC), a single pane-of-glass management platform across virtual and physical networking environments
  • Enhanced network resiliency by combining HP EVI with the capabilities of HP Intelligent Resilient Framework (IRF), an HP innovation that allows multiple switches to be virtualized and operated as a single switch


Deploy multitenancy across data centers


The new HP Multitenant Device Context (MDC) software enables a single physical switch to be partitioned to create four virtual logical switches across the data center network. You can optimize your networking resources for multiple secure isolated department functions like finance, human resources and engineering, while reducing the number of network devices in the data center by 75 percent. 


Additional HP MDC benefits include:


  • Rapid allocation of resources with separate lines of accessibility and communication (multi-tenant capabilities) with one physical switch 
  • Lowered total cost of ownership (TCO)


Use cases


Unlike other legacy solutions in the market, HP allows combining HP EVI with HP MDC. Each EVI can run multiple unique instances of MDC, which allows you to benefit from simplified and faster data center interconnectivity over any existing network, while delivering on multitenancy across data centers.


Disaster recover & business continuity

Up and running in only five configuration steps per site, HP EVI interconnects your cloud data centers in minutes, not months.


Long distance workload & data mobility

HPs’ Ethernet Virtual Interconnect (EVI) lets you move virtual machines and data from one data center to another. No network redesign required. EVI can be deployed over your existing network.


Datacenter expansion/consolidation

When applications need to be migrated, EVI enables long-distance live VM migration without loss of service and no business downtime as part of a data center migration, maintenance or consolidation.
