Cisco Virtualized Multiservice Data Center (VMDC) Virtual Services Architecture (VSA) 1.0
Design Guide
Chapter 1 VMDC VSA 1.0 Introduction
Overview
Solution Proposal
To address the identified requirements, we modified the Unified Computing component of the VMDC
architecture, shifting virtualized service functions from the Unified Fabric/Data Center Networking
portions of the infrastructure.

In general, the solution comprises three modular layers:
1.
Unified Computing and Integrated Systems (UCIS), providing server and application virtualization,
typically consisting of FlexPods and Vblocks.

The solution is complemented by Cloud Service Management components that enable end to end
provisioning and orchestration, along with monitoring and assurance.

High Level VMDC Solution
VMDC VSA 1.0 shifts network service functions to the UCIS in a way that leverages existing design
guidance for the Unified Fabric and DCI layers, along with previous guidance for the UCIS layers in
terms of compute and storage for application workloads. We maintained the following assumptions:

•
Previous design guidance for UCIS (FlexPod, Vblock) components applies. VMDC VSA 1.0
validation was performed on the latest FlexPod release. Applications validated on FlexPod or
Vblock continue to function on the overall VMDC architecture.

There are no top-level management and orchestration components in VMDC VSA 1.0: orchestration
and service assurance are addressed in separate, parallel VMDC programs.
