EMC DISASTER RECOVERYAS A SERVICE

A single outage can make business owners painfully aware of the im-portance of disaster recovery (DR) planning. However, an effective DR strategy is about more than simply anticipating a data center out-age—it’s about ensuring minimal business impact. Unfortunately, the lack of a DR plan can have far reaching consequences. According to the National Archives and Records Administration, 93% of businesses that lose their data centers for ten or more days will file bankruptcy within a year.

Enterprises must pro-actively address the potential business impact that a data center outage would have on the organization, and the true costs associated with losing access to mis-sion critical applications. At the same time, enterprises must determine rea-sonable expectations for the length of recovery downtime (the recovery time objective, or RTO), and how much data loss is acceptable, if any (the recovery point objective, or RPO).

Establishing a DR plan aligned with business needs and operational imperatives can create challenges for organizations with demanding RPO and RTO requirements but little appe-tite for the investment, deployment, and on-going management of a DR environment.

Managed storage solutions offer enterprises a cost-effective approach to ensuring business continuity (BC) without sacrificing reliable, sin-gle-click recovery of vital data and applications. In fact, IDC projects Storage-in-the-Cloud to be a $15B market by 2015, with a 35.3% CAGR for Continuity (Fig. 1).

Service providers (SPs) with managed storage solutions are ideally posi-tioned to add business continuity to their portfolio of managed offerings by adding replication and recovery services and making these new val-ue-added services available to their installed base. With a combination of managed network, storage and data center infrastructure already in place, service providers can quickly offer hy-brid cloud service models supporting enterprise business continuity.

A storage-in-the-cloud offering delivers added value to existing customers, while enabling providers to reclaim underutilized capacity, affording network providers easy access to on-net customer locations, and allowing many data center oper-ators to leverage the customer data they have within their premises.

For the smaller enterprise with DR needs but limited resources to deploy and manage a DR solution, cloud multi-tenancy can make new offerings very attractive and afford-able, with no capital investment to amortize, more predictable running cost, and service level guarantees.

DISASTER RECOVERY TO THE CLOUDThe first model of business continu-ance through a cloud service, DR to the Cloud, addresses the complete restoration of business operations by replicating the enterprise private cloud application environment, in addition to replicating the data hosted by the applications running in that private cloud (Fig. 2).

Unlike a backup model, where data must be restored to the original, run-ning application environment, when a disaster prevents the data center from returning to normal operations DR to the Cloud allows the replicated data to be brought up at the service provider site, temporarily running on a replicated application environ-ment to ensure complete continuity of business operations until service at the original customer site can be restored.

DISASTER RECOVERY IN THE CLOUDThe second model of business continuance through a cloud service, Disaster Recovery in the Cloud, ad-ditionally addresses outages within the service provider environment, providing another level of protection for the enterprise in that the primary service provider data site (Site A in Fig. 3) is now replicated to a geo-graphically disparate secondary site (Site B in Fig.3), potentially outside the directly affected geography in a regional disaster.

This model simultaneously provides business continuance for service provider operations as well as the service provider’s customers.

DISASTER RECOVERY AS A SERVICEThe EMC DRaaS solution brings eco-nomic justification for cloud-based high availability and protection, reducing financial risk and creating value for both providers and DRaaS customers.

This DRaaS solution lets service pro-viders extend a cloud-based recovery service to a variety of customer cat-egories, from on-premise, managed customer environments, to single or multi-tenant hybrid or off-premise public clouds, offering substantial economic benefits through resource sharing and more efficient recovery scenarios leveraging cloud-based automation.

EMC DRAAS AND VMWARE SITE RECOVERY MANAGERVMware Site Recovery Manager (SRM) is the leading disaster recov-ery solution for virtualized appli-cation environments, assuring fast restoration of vSphere infrastructure.SRM leverages EMC RecoverPoint to centralize management of recov-ery plans, enabling non-disruptive testing, and automating any point in time (PiT) site recovery and migra-tion workflows.

EMC Storage Replication Adapter (SRA), integrates SRM with RecoverPoint to support replication between sites.

THREE FOUNDATIONAL USE CASESThe RecoverPoint system, consist-ing of clusters of physical or virtual RecoverPoint Appliances (RPA or vRPA) at each site, can be shared by, or dedicated to tenants, depending on SP preferences, or a specific SLA being used for the service.

Some environments will contain tenants that require dedicated resources, while other tenants will have their requirements satisfied within a shared RPA System. For both DR in the Cloud and DR to the Cloud, Use Case 1 in Fig. 4 shows each RecoverPoint system (the Production

• The need to protect storage used within SP or customer sites

• The need to protect both SP and customer remote locations using the same service, simplifying operations and lowering costs

• The need to access all data at any point in time.

Combining industry leading repli-cation and recovery platforms for virtualized applications, EMC offers a DRaaS solution based on EMC RecoverPoint, EMC VNX storage, and VMware vCenter Site Recovery Manager.

EMC RECOVERPOINTOffering point-in-time recoverabil-ity from mixed server and storage environments through synchronous or asynchronous replication, EMC RecoverPoint (RPA) is an enter-prise-scale solution designed to protect application data on hetero-geneous SAN-attached servers and storage arrays. Customers imple-menting RecoverPoint have expe-rienced dramatic improvements in application protection and recovery times compared to traditional host and array snapshots.

EMC VNX SERIES STORAGEOptimized for virtual applications, EMC VNX series delivers high-per-forming unified storage with unsur-passed simplicity and efficiency, letting service providers achieve new levels of performance, protection, compliance, and ease of manage-ment. In this solution, VNX adds significant value by hosting Recover-Point write-splitting, essential to the replication function. Additionally, VNX handles connectivity to both FC and iSCSI initiators, simultaneously supporting both SAN networking block storage environments.

Site/Recovery Site pairs of RP clusters) as being specifically dedicated to each tenant, whether the system is physical (RPA) or virtual (vRPA).

In Fig. 5, all the resources in the RPA system are shared between the at-tached clients, fulfilling the DR in the Cloud model (since the SP controls the DR infrastructure at both sites), but not DR to the Cloud (where the SP does not have strict control over each customer site’s DR infrastruc-ture). Although this example shows vRPA, the solution is similar for RPA.

RPA resources can be shared sym-metrically or asymmetrically between tenants depending on service level agreement (SLA). This could mean that all tenants (four in this exam-ple), would receive an equal share of the maximum number of RPA re-sources, or the SP might allocate or dedicate them in a weighted fashion depending upon tenant require-ments.

The use case in Fig. 6 shows how a combination of mixed and dedicated RPA or vRPA can be configured. Note that Tenant D is a multi-subtenant composite.

CONCLUSIONAs organizations increase their use of SP managed services their DR challenges can also grow.
