Overview
 Abstract
• 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
an 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.
 Objectives
• 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.
• 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.

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

SDDC’s Resource Model: Objective 1
In this section we describe the disaggregated I/O resource model
employed to facilitate the use of virtualized Ethernet and Block
devices in a Software Defined Data Center.

Differentiated Infrastructure Service Delivery
Areas for Opportunity and Cause for Concern
1. Improving All Facets of Security
2. Increasing the Breadth of Available Instance Types within a
Resource Class
3. Decreasing Resource Delivery Time/Improving Capacity
Management
4. Increasing Average Utilization by Improving Resource
Scheduling
5. Decreasing Frequency of Outages, both Scheduled and
Unscheduled
6. Decreasing the Time to Recover from an Outage
