Dell EMC Isilon

Dell EMC Isilon is a scale-out NAS storage platform under Dell EMC, originally developed by Isilon Systems, later acquired by EMC, and eventually integrated into Dell Technologies. It is known for high scalability and support for big data workloads.

Isilon Systems was established in Seattle in 2001 by Sujal Patel and Paul Mikesell to address the difficulty of managing rapidly expanding collections of unstructured digital information. Its approach combined server-like storage nodes with a clustered file system so that customers could scale a shared storage environment without managing every appliance as a separate system. The company targeted digital-content producers and other industries whose data consisted largely of files rather than structured database records. The technical foundation of the platform was OneFS, an operating system derived from FreeBSD. OneFS coordinated storage nodes as a single distributed resource, providing a unified namespace and allowing files to be accessed through standard enterprise protocols. A cluster generally required three or more nodes, and capacity and performance could be expanded by adding nodes. Data protection used distributed techniques, including Reed–Solomon-based erasure coding, to spread data and parity across the cluster. This design supported resilience while making the storage pool appear as one file system to applications and users. Isilon became publicly traded on December 16, 2006. By that stage, it used both a direct field-sales organization and a channel program involving more than 100 resellers and distributors. Its customer base included organizations such as NBC Universal, Cedars-Sinai, Kelman Technologies and Kodak. The company’s early public-market performance was disappointing, and executive changes followed. Chief executive Steve Goldman and chief financial officer Stu Fuhlendorf departed, while co-founder Sujal Patel returned to the company as chief executive in October 2007. In April 2008, Isilon disclosed revenue-recognition events from the prior management period to the Securities and Exchange Commission. Several previously submitted 2006 and 2007 earnings reports were revised, and the company introduced a new revenue-recognition policy. These events became a significant part of Isilon’s corporate history because they occurred while the company was attempting to establish a record of sustained profitability. EMC acquired Isilon Systems in November 2010 for approximately $2.25 billion. EMC presented the acquisition as a way to strengthen its storage infrastructure for private and public clouds and for large-scale data-intensive workloads. Examples cited in connection with the platform included gene sequencing, online streaming and oil-and-gas seismic analysis. After the transaction, Isilon remained a recognizable product family within EMC’s storage portfolio, with the technology serving customers in media, entertainment, technology, financial and other sectors. The EMC product strategy expanded the platform from a clustered hardware appliance into a broader data-management environment. OneFS continued to provide the core operating layer, while CloudPools supported movement of data between primary storage and cloud or other tiers. IsilonSD Edge offered a software-defined form of the platform for remote or smaller sites. EMC also linked Isilon to data-lake and Hadoop initiatives. Support for HDFS allowed analytics frameworks to process files held on the storage system, and EMC’s relationship with Cloudera was intended to make Hadoop-based analytics more accessible to existing Isilon customers. In 2017, Dell EMC introduced systems using the Infinity architecture. The design emphasized higher input/output operations, throughput, capacity and physical density, while allowing customers to update selected components without replacing an entire node. The product line subsequently moved toward the PowerScale identity. OneFS 9.0, released in June 2020, marked the beginning of the PowerScale moniker. Under Dell Technologies, PowerScale represents the continuation of the Isilon architecture and software heritage. The historical Isilon brand therefore remains important as the origin of a platform now positioned as Dell Technologies’ scale-out file and unstructured-data storage offering.

  Sujal Patel and Paul Mikesell establish Isilon Systems in Seattle to develop clustered storage for digital content and other unstructured data.

Enterprise scale-out file storage for organizations with rapidly growing volumes of unstructured data. The platform emphasizes a single expandable namespace, clustered performance, simplified administration, multi-protocol access, data protection and integration with analytics and cloud-storage workflows.

• Clustered storage operating system

  OneFS

  OneFS is the FreeBSD-derived operating system at the core of Isilon and PowerScale systems. It joins independent nodes into one logical storage resource, coordinates data and metadata across the cluster, and provides a unified namespace. OneFS supports NFS, SMB, FTP and HDFS access, together with distributed protection, management, high availability and scale-out expansion.

• Scale-out NAS hardware

  Isilon clustered storage systems

  Isilon systems are built from three or more integrated storage nodes connected through a cluster network. Each node contributes processing, memory, networking and storage resources to a shared file system. The architecture is intended for large unstructured-data repositories and can be expanded by adding nodes rather than replacing the complete system.

  IsilonSD Edge

  IsilonSD Edge was announced as a scaled-down, software-based Isilon offering for remote locations and smaller deployments. It extended the platform’s clustered-storage concept beyond the main appliance portfolio and was positioned as part of EMC’s edge-to-core-to-cloud data-lake strategy.
