Solution Brief: Commvault HyperScale™ Software


Enterprise IT Shifts

Enterprise IT is being transformed with the maturing of public cloud providers that offer compute, storage and application services with unprecedented elasticity, scale, resiliency and availability, on a consumption based economic model. However, the choice between public cloud and on-premises infrastructure is not a binary one.

As some workloads shift to the cloud, enterprises arealso looking to transform their internal data centers and service offerings for cloud-like scale, flexibility, resiliency and operational methods leading to similar economic outcomes. To this end, architects are augmenting or replacing traditional, proprietary and single purpose IT infrastructure and applications with software defined services, distributed processing, big-data applications and hyper converged architectures running on general purpose, easily replaceable hardware.

Transforming mission critical applications and workloads could be difficult and disruptive, not so for secondary infrastructure. By some estimates 50-70%1 of infrastructure capacity is used for secondary workloads and storage. Businesses can accelerate their transformation initiatives with less disruption by targeting this secondary infrastructure. Commvault HyperScale Software enables this shift for secondary storage and workloads, driving cloud-like economics and critical services using secondary data, while extending these services into the public cloud.

Traditional Backup Architecture and Challenges

While backup processes are mature, traditional architectures are not suited to adapt to new cloud centric infrastructure and operations. Traditional enterprise backup centers around controller based, proprietary, single purpose disk storage devices or appliances. Dedicated, powerful and expensive media servers run the backup software and many of the storage management services like deduplication and encryption. Separate media servers handle creation of secondary copies to disk arrays or tape, depending on data retention need. As enterprises seek to adopt public cloud storage, these legacy architectures require dedicated cloud gateways or more media servers to handle the additional burden of pushing data copies to public cloud. While this architecture worked for several years and continues to be useful in traditional IT enterprises, it has several limitations that inhibit cloud oriented transformations for better service offerings and economics.

Backup architecture schematic

High Infrastructure Costs: Proprietary storage devices or appliances, dedicated proxy servers and single purpose media servers with redundant components increase costs. Frequent forklift upgrades and repurchases tied to life of hardware.

Complex Management and Operations: Every component is configured, upgraded and managed separately increasing operating burden. Aligning policies and rules to meet desired service levels across the disparate elements can be challenging.

Limited Resiliency and Availability: Controller based architecture provides limited resiliency and in many cases necessitates doubling the infrastructure for availability, increasing costs and complexity.

Limited Service Offerings: Single purpose media servers and storage constrain performance and access capabilities, offering only nightly backup and long restore services, limiting the use of these secondary copies.

Poor Cloud Integration: The legacy approaches often use public cloud simply as a long-term retention tier with no option to reuse the data, thus minimizing the potential of cloud to accelerate business operations. In many cases this data copy to public cloud requires expensive, dedicated gateway devices, negating any potential cost savings from the cloud.

Commvault HyperScale Software

The Commvault HyperScale Software consolidates all the roles performed by discrete servers in the traditional data protection architecture into a single software defined stack. The software spans multiple storage nodes running on general purpose servers, creating a massively addressable storage pool with built-in enterprise class data management capabilities. This eliminates the need for dedicated media servers, proprietary controller based storage devices and cloud gateways, reducing infrastructure costs dramatically.

All data management and storage optimization operations are distributed across the nodes, with each node capable of taking on multiple roles on demand, including moving data to cloud. Software defined resiliency and availability allows enterprises to fix failed components or nodes, mix and match different types of nodes as needed and replace or upgrade nodes seamlessly without disrupting operations or data availability.

Cloud Ready Data Management for the cost of replacing legacy Purpose Built Backup Appliance (PBBA)

By shifting the secondary storage and data management infrastructure to this architecture, enterprises can go a long way in transforming their data centers to be as operationally efficient, resilient and scalable as public cloud infrastructure. Lower hardware costs, operational efficiencies and simplified support allows the replacement of limted and legacy backup tools with a modern cloud enabled data management solution at the cost of replacing legacy PBBA. More importantly, this architecture, which extends into public cloud, allows enterprises to offer consistent sets of services to all workloads running on-premises or in public cloud, independent of the underlying infrastructure for true cloud based data management.
