Dell EMC Isilon is a scale out network-attached storage platform offered by Dell EMC for high-volume storage, backup and archiving of unstructured data. [1] It provides a cluster-based storage array based on industry standard hardware, and is scalable to 50 petabytes in a single filesystem using its FreeBSD-derived OneFS file system. [2]
An Isilon clustered storage system is composed of three or more nodes. Each node is a server integrated with proprietary operating system software called OneFS (based on FreeBSD [3] ), which unifies a cluster of nodes into a single shared resource. [4] [5]
Isilon Systems was a computer hardware and software company founded in 2001 by Sujal Patel and Paul Mikesell, a 1996 graduate of the University of Maryland College of Computer, Mathematical, and Natural Sciences. [6] It was headquartered in Seattle, Washington. [7] It sold clustered file system hardware and software for digital content and other unstructured data to a variety of industries. [8]
Isilon Systems became a publicly traded company on December 16, 2006. By this time, Isilon was selling its products indirectly through a channel partner program that included over 100 resellers and distributors, as well as directly through a field sales force. Its customers included NBC Universal, Cedars-Sinai, Kelman Technologies, and Kodak, among others. [8]
Poor initial performance of the new public company led to management changes in 2007 that brought back founder Sujal Patel as CEO. [9] In 2008, details emerged around an internal audit of Isilon System’s financials that led to a restatement of earnings. [10] Just before the company would have announced four profitable quarters in a row – the first profitable year in the company’s history – Isilon Systems was acquired by EMC Corporation in November 2010 for $2.25 billion. [11]
EMC said that with its acquisition of Isilon, it would be better able to provide storage infrastructure for private and public cloud environments, with a focus on so-called big data, like gene sequencing, online streaming, and oil and natural gas seismic studies. [12] At the time of acquisition, the list of Isilon’s clients had grown to include Sony, XM Radio, LexisNexis, Facebook, MySpace, Adobe, and several major movie studios and TV networks. [13]
On November 10, 2015, EMC announced an expansion of its Isilon NAS portfolio with a scaled-down, software storage system for remote locations, a cloud migration application and high-availability upgrades for Isilon OneFS. The two software additions, IsilonSD Edge and CloudPools, will be available alongside the new version of OneFS in 2016. They are part of the vendor's data lakes strategy for storing and managing unstructured data in large repositories. [14] The new offerings will, according to one analyst, deliver a data lake-ready platform to enterprises with high-speed data analytics, and are aimed at three aspects of the Data Lake, the edge, the core, and the cloud. [15]
On May 8, 2017, Dell EMC announced a new line of Isilon systems based on the "Infinity" architecture that "can hit up to 6x the IOPS, 11x the throughput, and ... twice the capacity over the previous generation Isilon." [16] The new Infinity architecture is modular, allowing system owners to increase each component as needed. Drive density has increased, with up to 60 drives in 4U of rack space, almost twice that of the previous generation. This also means the new nodes are physically smaller. Up to four nodes can sit blade-style in 4U of rack space. And Isilon now supports CPU and drive updates as they become available, without replacing the whole node. [17]
In June 2020, with the release of OneFS 9.0, the product line also started using the "PowerScale" moniker. [18] [19] [20]
Isilon clustered storage system architecture consists of independent nodes that are integrated with the OneFS operating system software. [21] The systems can be installed in standard data center environments and are accessible to users and applications running Windows, Unix/Linux and Mac operating systems using industry standard file sharing protocols over standard Gigabit or 10-Gigabit Ethernet. Nodes within the clustered storage system communicate with each other over a dedicated 10Gb Ethernet local area network (Infiniband in legacy installations). The architecture is designed so that each node has full visibility and write/read access to or from a single expandable file system. [8]
Data protection is formed using Reed–Solomon error correction coding. When a file is written it is spread across several nodes using parity calculated by which level you set the whole or parts of the cluster to. [2]
Isilon provides multi-protocol access to files using NFS, SMB or FTP. In addition, Isilon supports HDFS as a protocol allowing Hadoop analytics [22] to be performed on files resident on the storage. Data can be stored using one protocol and accessed using another protocol. The key building blocks for Isilon include the OneFS operating system, the NAS architecture, the scale-out data lakes, and other enterprise features.
Recent deals between EMC and Cloudera will allow the Cloudera Enterprise Hadoop kit to be sold directly from EMC and its channel partners. The deal may benefit the thousands of EMC Isilon customers with existing data lakes by providing a base for running analytic processes on their data, giving them access to Impala, Cloudera's open source, massively parallel processing SQL query engine that runs on Hadoop.

Apache Hadoop is a collection of open-source software utilities that facilitates using a network of many computers to solve problems involving massive amounts of data and computation. It provides a software framework for distributed storage and processing of big data using the MapReduce programming model. Hadoop was originally designed for computer clusters built from commodity hardware, which is still the common use. It has since also found use on clusters of higher-end hardware. All the modules in Hadoop are designed with a fundamental assumption that hardware failures are common occurrences and should be automatically handled by the framework.
Exanet, Ltd. was an Israeli software company that provided scalable network-attached storage software solutions to partners. Exanet software was hardware independent.

After the company went into temporary receivership, on February 19, 2010 Exanet's intellectual property was acquired by Dell.
A clustered file system (CFS) is a file system which is shared by being simultaneously mounted on multiple servers. There are several approaches to clustering, most of which do not employ a clustered file system. Clustered file systems can provide features like location-independent addressing and redundancy which improve reliability or reduce the complexity of the other parts of the cluster. Parallel file systems are a type of clustered file system that spread data across multiple storage nodes, usually for redundancy or performance.

The OneFS File System is a parallel distributed networked file system designed by Isilon Systems and is the basis for the Isilon Scale-out Storage Platform. The OneFS file system is controlled and managed by the OneFS Operating System, a FreeBSD variant.
Data-intensive computing is a class of parallel computing applications which use a data parallel approach to process large volumes of data typically terabytes or petabytes in size and typically referred to as big data. Computing applications that devote most of their execution time to computational requirements are deemed compute-intensive, whereas applications are deemed data-intensive require large volumes of data and devote most of their processing time to I/O and manipulation of data.
Converged storage is a storage architecture that combines storage and computing resources into a single entity. This can result in the development of platforms for server centric, storage centric or hybrid workloads where applications and data come together to improve application performance and delivery. The combination of storage and compute differs to the traditional IT model in which computation and storage take place in separate or siloed computer equipment. The traditional model requires discrete provisioning changes, such as upgrades and planned migrations, in the face of server load changes, which are increasingly dynamic with virtualization, where converged storage increases the supply of resources along with new VM demands in parallel.
Dell Fluid File System, or FluidFS, is a shared-disk filesystem made by Dell that provides distributed file systems to clients. Customers buy an appliance: a combination of purpose-built network-attached storage (NAS) controllers with integrated primary and backup power supplies attached to block level storage via the iSCSI or Fiber Channel protocol. A single Dell FluidFS appliance consists of two controllers operating in concert connecting to the back-end storage area network (SAN). Depending on the storage capacity requirements and user preference, FluidFS version 4 NAS appliances can be used with Compellent or EqualLogic SAN arrays. The EqualLogic FS7600 and FS7610 connect to the client network and to Dell's EqualLogic arrays with either 1 Gbit/s (FS7600) or 10 Gbit/s (FS7610) iSCSI protocol. For Compellent, FluidFS is available with either 1 Gbit/s or 10 Gbit/s iSCSI connectivity to the client network and connection to the backend Compellent SAN can be either 8 Gbit/s Fibre Channel or 10 Gbit/s iSCSI.
ViPR Controller is a software-defined storage offering from EMC Corporation announced on May 6, 2013, at EMC World. ViPR abstracts storage from disparate arrays into a single pool of storage capacity that "makes it easier to manage and automate its own data-storage devices and those made by competitors." ViPR became generally available September 27, 2013.
A distributed file system for cloud is a file system that allows many clients to have access to data and supports operations on that data. Each data file may be partitioned into several parts called chunks. Each chunk may be stored on different remote machines, facilitating the parallel execution of applications. Typically, data is stored in files in a hierarchical tree, where the nodes represent directories. There are several ways to share files in a distributed architecture: each solution must be suitable for a certain type of application, depending on how complex the application is. Meanwhile, the security of the system must be ensured. Confidentiality, availability and integrity are the main keys for a secure system.
Dell Technologies PowerFlex, is a commercial software-defined storage product from Dell Technologies that creates a server-based storage area network (SAN) from local server storage using x86 servers. It converts this direct-attached storage into shared block storage that runs over an IP-based network.
ONTAP or Data ONTAP or Clustered Data ONTAP (cDOT) or Data ONTAP 7-Mode is NetApp's proprietary operating system used in storage disk arrays such as NetApp FAS and AFF, ONTAP Select, and Cloud Volumes ONTAP. With the release of version 9.0, NetApp decided to simplify the Data ONTAP name and removed the word "Data" from it, removed the 7-Mode image, therefore, ONTAP 9 is the successor of Clustered Data ONTAP 8.
