This document is an Addendum to the Disaster Recovery as a Service (DRaaS) 2.0 Implementation Guide. The Cisco DRaaS 2.0 solution addresses the architecture and implementation required to provide disaster recovery services. The solution is layered on top of the Cisco VMDC VSA 1.0 cloud reference architecture, which provides the basic framework and technologies required to support multi-tenant cloud implementations. This Addendum addresses two key components of the solution that are not addressed in the DRaaS 2.0 Implementation Guide:
Disaster Recovery Application—InMage ScoutCloud provides DR services for both physical-to-virtual (P2V) and virtual-to-virtual (V2V) workloads. The host-based replication technology replicates the changes made on the servers at the production site to one or more recovery locations, including Cloud SP sites.
VMware Virtual SAN—Virtual SAN is a new software-defined storage solution that is fully integrated with vSphere. Virtual SAN aggregates locally attached disks in a vSphere cluster to create a storage solution-a shared datastore-that rapidly can be provisioned from VMware vCenter™ during VM provisioning operations. VMware Virtual SAN provides another storage option that may be attractive for some deployments.
