Solution Overview

The Cisco ® Virtualized Multi-Tenant Data Center (VMDC) 2.0 solution is designed for enterprises building cloud-capable infrastructure and service providers deploying an infrastructure-as-a-service (IaaS) model for the data center. It integrates various Cisco and third-party products that are part of the cloud computing ecosystem (Figure 1).

Figure 1. Solution Topology

Customer Benefits

The Cisco VMDC architecture is a validated design of a virtualized multi-tenant infrastructure that confers several benefits:

• Predictable deployment time and cost: Use of a validated, scalable, modular architecture that incorporates Cisco's pod designs and integrated compute stacks

• Rapid tenant provisioning and management on a unified infrastructure: Use of a comprehensive automation framework with portal-based resource provisioning and management capabilities

• Efficient and flexible workload deployment: Use of shared resource pools and service catalogs

Architecture Features

• Infrastructure

– Use of two different integrated compute stacks: Vblock Infrastructure Packages, defined by the Virtual Computing Environment (VCE) coalition,1 and a Cisco, NetApp, and VMware stack

– Pod-based design (see Figure 1): Two baseline scale points (compact and large pods) validated

– Workload mobility and disaster recovery capabilities: For business continuance

– Security in each module of the architecture: Integrated compute stacks, pod, and data center interconnect

• Tenant scale and service tiers

– End-to-end separation of tenants on top of unified infrastructure: Validated scaling of from 30 to 150 tenants

– Service-tier-based design to allow differentiated services for tenants (see Table 1): Validation of a three-tier model

– Support for scalable and flexible mix of typical enterprise workloads per tenant: Support for a range from a few hundred to multiple thousand virtual machines

• Tenant and workload management

– Lifecycle management for tenants and workload using the BMC Cloud Lifecycle Management (CLM) product

– Fully templated process to create, monitor, and delete tenants within the service-tier framework

– Service catalog and portal capability for tenant-focused workload management

Table 1 lists the service tiers that were used to validate the multi-tenant service capability of the Cisco VMDC 2.0 solution. The chosen service tiers reflect a typical set of parameters used by customers to create a differentiated IT environment. Note that the three tiers are only an example to demonstrate the flexibility and scalability of the solution.
