Commvault® Reference Design Specification
Commvault HyperScale™ Software on Dell EMC® PowerEdge® R740xd
Introduction to Commvault HyperScale Software
With Commvault HyperScale™ Technology, you can build a unified, modern data protection and management platform that delivers cloud-like services on-premises. The purpose of this technical specification is to detail the Dell EMC PowerEdge R740XD server components for the Commvault validated reference design. By building these services on a scale-out infrastructure and leveraging Commvault capabilities, you’ll enable:
- Cloud-like agility, resiliency and availability to on-premises data and applications
- Greater end-user efficiency through automation and self-service capabilities
- Improved hardware utilization and optimized costs from general-purpose hardware
- Seamless storage scalability with predictable performance without requiring forklift upgrades
- Better, more secure data protection, utilization and movement by eliminating point product and data silos
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 limited and legacy backup tools with a modern cloud enabled data management solution at the cost of replacing legacy purpose-built backup appliance (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.
General availability designation
This configuration is classified as general availability design, meaning it has been tested and validated as per the Commvault Validated Reference Design Program. This configuration is subject to change due to updated part numbers or replacement hardware due to hardware life cycle. Validated reference designs are developed to provide optimized costs and match performance requirements for every customer. Commvault collaborates with Dell EMC to create fully supported design specifications. Substitutions or modifications to validated design specifications could result in unsupported configurations. Any substitutions or modifications to validated configurations must be approved by both Commvault and Dell EMC. This configuration is currently orderable for customer deployment and supported through Commvault support channels.
How to use this document
This document details the necessary design components of the Commvault HyperScale™ Technology architecture, providing the key components required when purchasing and configuring the infrastructure for a Commvault HyperScale™ Software solution. Commvault reference designs deliver validated configurations with leading hardware vendor technology that provide validated designs complemented by best practices that will accelerate ROI, reduce complexity, and add customer value.
The document is broken into a high-level component section detailing the configuration and specific component options that can be selected to satisfy storage capacity and density requirements. Each subsection provides guidance for ordering configurations.
This document does not cover overall architecture and design of the Commvault HyperScale solution, and should be considered as a supplement specific to Dell EMC.

Boot and metadata storage options
Boot storage houses the operating system and core Commvault HyperScale binaries, while the metadata storage provides caching areas for such operations as deduplication, indexing, and extents. Boot and metadata can be either configured together as a single unit or housed separately. There have been times that specific hardware components, surrounding flash storage, have elongated order cycle times and are typically beyond Dell EMC’s or partner’s control.
Data storage options
Data storage houses the data footprint for the customer environment. Data storage configuration directly impacts the amount of data that each node can accommodate.
When deploying nodes inside of the same block (e.g. 3-node initial configuration), choose identical hard disk drives (HDDs). If the nodes in a block have different HDD sizes, the lowest size will be chosen for the data storage, which would lead to wasted resources on nodes with larger HDDs.
Separate node blocks in the same grid may use different HDDs (e.g. mixing a 3 node 6 TB block with a second 3 node 10 TB block in the same grid).
Overall sizing and retention varies per customer and therefore is beyond the scope of this document. Please refer to Commvault HyperScale Technology sizing documentation to determine the drive size (and node quantity) required for the specific deployment.
Commvault HyperScale nodes can optionally be initially deployed with partially filled HDD slots. As additional storage is required, nodes can be scaled vertically by filling empty HDD slots. Initial deployment and vertical scaling must be done in multiples of 6 drives per node. All nodes within a block must have the same number of HDD and must scale vertically at the same rate (e.g. start a block of 3 nodes with 6 of 24 drive slots filled in all nodes; expand all three nodes simultaneously by adding 6 drives to each node).
A minimum of two (2) 10 GB ports are required for Commvault HyperScale installs, 1 for incoming data and 1 for storage communication between the nodes. It is recommended to have 4 ports, 2 for data and 2 for storage for failover and redundancy. These builds have been designed with this recommendation.
Optional I/O add-on cards
The design includes all core components to work with Commvault HyperScale Technology. There are specific instances where additional I/O connectivity is desired as part of the overall solution. Optional I/O cards for SAS and fibre channel connectivity are validated and included as part of the design.
SAS connectivity is typically used for direct tape integration, while fibre channel cards are used for Commvault IntelliSnap® operations or tape libraries.
