Description of ONTAP¶

ONTAP¶

Scaling performance while controlling costs is one of the most challenging efforts in the data center. High-performance, technical computing, and digital media content applications place extreme demands on storage systems. Compute clusters running these applications can require multiple gigabytes per second of performance and many terabytes — or even petabytes — of capacity. To maintain peak application performance, users must be able to add storage and move data between systems and tiers of storage without disrupting ongoing operations. At the same time, to control costs, users must be able to effectively manage the storage environment.

ONTAP addresses these challenges and provides high-performance and high-capacity requirements. It enables organizations to address faster time to market by providing massive throughput and the scalability necessary to meet the demanding requirements of high-performance computing and virtualization infrastructures. These high-performance levels address the growing demands of performance, manageability, and reliability for large Linux, UNIX, Microsoft, or VMware clusters.

ONTAP is an operating system from NetApp that includes:

• Nondisruptive operations based on a clustered file system hosted on interconnected nodes

• Support for deployment across a wide range of architectures, such as All Flash FAS (AFF) systems and hybrid-flash FAS systems, converged infrastructure solutions (FlexPod), on commodity servers as SDS (ONTAP Select), using third-party arrays (FlexArrays), near cloud deployments (NetApp Private Storage) and in cloud deployments (ONTAP Cloud)

• Multinode scaling with global namespacing technologies

• NetApp FlexVol for storage virtualization

• NetApp backup and recovery solutions based on local Snapshot copies, replication, and mirroring

NetApp’s storage clustering feature within ONTAP provides a number of key benefits, including the ability to:

Accelerate Performance

ONTAP uses a clustered file system technology to provide maximum input/output (I/O) throughput and remove the bottlenecks that affect production. Information can be striped as volumes across any or all of the storage controllers and disks in the system, which enables balanced levels of throughput for even a single file or volume and allows technical teams to run multiple compute jobs concurrently. When many compute nodes simultaneously require data, you can use load-balancing mirrors within ONTAP with a clustering system or add NetApp FlexCache storage accelerators in front of the system to deliver much higher read throughput.

Simplify Storage and Data Management

ONTAP supports fully integrated storage solutions that are easy to install, manage, and maintain. Enhancing this with its global namespace capability, administrators can simplify client-side management by mapping all data volumes in the cluster into a file system tree structure that automatically maps or remaps servers to their data, even if that data is moved. By offering a single system image across multiple storage nodes, the global namespace eliminates the need for complex automounter maps and symbolic link scripts.

Improve Data Access

Storage is virtualized at the file system level to enable all compute nodes to mount a single file system, access all stored data, and automatically accommodate physical storage changes that are fully transparent to the compute cluster. Each client can access a huge pool of information residing anywhere in the storage cluster through a single mount point.

Keep Resources in Balance Without Disrupting Operations

As storage nodes are added to the cluster, physical resources, including CPU, cache memory, network I/O bandwidth, and disk I/O bandwidth, are kept in balance automatically. ONTAP enables you to add storage and move data between storage controllers and tiers of storage without disrupting users and applications. This ushers in a whole new paradigm in which capacity increases, workload balancing, eliminating storage I/O hotspots, and component deprecation become normal parts of the data center without needing to schedule downtime. More importantly, these tasks are accomplished without the need to remount shares, modify client settings, or stop active workloads as is typically the case with traditional or other high-performance computing storage systems.

Simplify Installation and Maintenance

Using standard Network File System (NFS) and Common Internet File System (CIFS) protocols to access ONTAP systems without needing to install special clients, network stack filters, or code on each server in the compute cluster is the value of a unified storage product. The ONTAP architecture also reduces or eliminates routine capacity allocation and storage management tasks, resulting in more time to address organizational goals and objectives and less time spent managing storage.

Meet High-Availability Requirements

Along with stringent performance requirements, high reliability is important for technical applications and cluster computing. ONTAP leverages core NetApp software such as WAFL (Write Anywhere File Layout), RAID-DP, and NetApp Snapshot. RAID-DP, a high-performance implementation of RAID 6, protects against double-disk failures, and transparent node failover automatically bypasses any failed components with no interruption in data availability. In addition to having no single point of failure, ONTAP supports the expansion or reconfiguration of the storage infrastructure while online, enabling applications to run uninterrupted as more storage capacity, processing power, and/or throughput is added.

Enable Continuous Operations

ONTAP is configured for continuous operation with the use of high-performance and modular NetApp storage components. Each system consists of one or more FAS/AFF building blocks where each building block is a high-availability pair of controllers (storage nodes). Multiple controller pairs form a single, integrated cluster. ONTAP uses Ethernet technology — Gigabit(Gb) and 10Gb — for server connections and for interconnecting controllers. Servers can also be connected through InfiniBand through the use of a gateway device. Each controller can support any mix of high-performance SAS and cost-effective SATA disk drives. Data can move nondisruptively between nodes or between different tiers of disk as performance requirements change. This capability makes sure that data center and IT administrators can maximize performance where needed while simultaneously improving capacity utilization.

Integrated Data Protection

ONTAP makes it possible to provide data protection to safeguard business operations and keep them running smoothly. Space-efficient Snapshots ensure business continuity and near-instant recovery from disasters. Asynchronous mirroring of volumes from one SVM to another, even across different clusters is provided using SnapMirror. Encryption of data at-rest is easy and efficient using NetApp Volume Encryption that is built into ONTAP. There is no requirement for special encrypting disks.

ONTAP Select¶

NetApp ONTAP Select provides the flexibility for customers to leverage the benefits of Software Defined Storage (SDS) economics, while enjoying enterprise-grade features and efficient data protection. ONTAP Select offers robust enterprise storage services that are deployed on commodity hardware from the comfort of a data center. It combines the best of the cloud, in terms of agility and granular capacity scaling, with the flexibility, resilience, and locality of on-premises storage. ONTAP Select software can be deployed in a data center or a remote office, with a flexible capacity-based license structure. Key benefits include:

Flexible Deployment

It is possible to deploy on your desired choice of commodity server, hypervisor, and media. You can also leverage your existing server infrastructure, HCI configurations, and external arrays for enterprise data services. Simplify operations and lower training requirements with uniform management across all storage based on ONTAP.

Cloudlike Agility

Spin up storage resources with cloudlike agility, from procurement to deployment in a day. It is also possible to easily move and replicate data non- disruptively across the hybrid cloud.

Enterprise Level Functionality

By using SDS built on ONTAP, the industry-leading data management platform, enterprise-class data reduction and data protection for NAS and SAN workloads can be obtained. Non-disruptive scaling and balancing of workloads can be done dynamically.
