The importance of making infrastructures smarter
Today’s IT infrastructures are being strained to the breaking point by new
The implications are significant:
Inability to serve customers
Supply chain delays

A key step to
becoming a
digital business
is the creation of
an intelligent
infrastructure.
It unlocks agility in
the organization,
allowing the
infrastructure to
anticipate and
adapt
to changing
business needs.
Delivering
competitive
advantage and,
ultimately, high
performance.
Unlocking the power of intelligence
An intelligent infrastructure is designed to:
1
3
4
2
Knowwhen extra capacity is needed, and even predict when that capacity might be required again.
Automatically configure unified communications for employees and secure connectivity to the core
enterprise.

Value of an intelligent
infrastructure is now measured not simply in IT capabilities, but in the new business outcomes made possible:
A more flexible, agile business
The ability to serve
• Market is driven by OTT that mask the value of the network
• Network and Infrastructure are perceived as the ‘limiting factor’: slow to change, complex, not standard, expensive

NFV-I Infrastructure key elements
• Fully virtual networking capabilities to provide Intra-DC L2-L7 networking services
• Inter-DC network infrastructure evolution in order to enable geo-clustering/extension of
a specific VNF through L2/L3 transport network capabilities
• Introduction of new network protocols (QinQ, VxLAN, TRILL, etc.) to overcome to
current scalability and actual technical constraint issued by current NEP solutions
Enabling Products key elements
• VMware NSX: implements L3/L7 virtual network functionalities (Firewalling, Load
Balacing, Routing, Access Control, …)
• Neutron (Open Stack): open stack module that enable L3/L7 functionalities on a
multi-hypervisor environment (KVM, XEN and other multi-hypervisor environment with ad hoc plugin)

NFV-I Software Defined Data Centers:
SW Defined Computing - Virtual Storage Focus
NFV-I Infrastructure key elements
• NFV-I leverage on Software Defined Storage paradigm in order to abstracts storage
capabilities and services by storage location or class of storage
• Integration with orchestration and Cloud Mgmt stack through the use of plug-ins and APIs
• Multi-Tenancy configuration in order to manage logically separated data and storage
services
• Class of service definition based on performance key metrics (ex. I/Ops latency, …) and
service type (block, file, object, …)
Enabling Products key elements
• ViPR: with ViPR the storage layer can be another virtual resource in the software-defined
data center. All data and resources managed by ViPR are accessible via open API
• NFVi storage infrastructure can be based on EMC ScaleIO, xTreamIO, VNX, Commodity
HW, etc.
