There has been quite a bit of marketing rhetoric around Software Defined Data Center (SDDC) since VMware’s acquisition of Nicira. In this session we explore the components of a SDDC. Our specific focus is on the composition of a SDDC’s resource model: Compute, Networking, and Storage. The emphasis is on the disaggregated I/O for Network and Storage resources.


Objective 1: Describe the disaggregated I/O resource model employed to facilitate the use of virtualized Ethernet and Block devices in a Software Defined Data Center.
After this session you will be able to:
Objective 2: Explain how end-user driven provisioning of virtual Ethernet devices and Block devices serve to decouple resource use from infrastructure management.
Objective 3: Describe some of the opportunities and challenges associated with employing disaggregate I/O.

  • 5. Infrastructure is a Differentiator when Delivered as a Service 1. Business Agility • • • Enable end-users (App-Dev) to deliver greater value to their business partner by providing them with self-service capabilities. Improve the quality and speed of delivery of IT services Enable IT to eliminate waste by running the Infrastructure at high levels of utilization 2. Dispelling the Myth that “Infrastructure is not a Differentiator” • • Is improving Business Agility predicated on wholesale adoption of Cloud and migrating all of Enterprise IT to Amazon/AWS? Or will Enterprise Customers Invest in making their own IT Services more competitive with Amazon/AWS? 3. Examples where Companies are deciding that Amazon/AWS’s model is right but believe “*Infrastructure is a Differentiator*” • • • • • Ebay Google Compute Engine (GCE) Microsoft Windows (Azure) PayPal Rackspace Hosting © Copyright 2013 EMC Corporation.
