Introduction to this guideAbout this guideThis guide describes how to prepare and plan for an Isilon hardware installation.Before implementing an Isilon cluster into the data workflow, it is important to identifythe best Isilon equipment and software requirements. Be sure to confirm that thefacility is ready to support the cluster.A cluster that includes an HD400 or a Generation 6 node in the data workflow includesunique characteristics of the respective node as described in this guide.The information in this guide provides a framework for the research that a SystemAdministrator or Facility Manager must conduct before powering on an Isilon node.For detailed information about the OneFS operating system, review OneFSdocumentation on the Online Support site (Online Support).Isilon scale-out NAS overviewThe Isilon scale-out NAS storage platform combines modular hardware with unifiedsoftware to harness unstructured data. Powered by the OneFS operating system, acluster delivers a scalable pool of storage with a global namespace.The unified software platform provides centralized web-based and command-lineadministration to manage the following features:lA cluster that runs a distributed file systemlScale-out nodes that add capacity and performancelStorage options that manage files and tieringlFlexible data protection and high availabilitylSoftware modules that control costs and optimize resourcesOneFS storage architectureIsilon takes a scale-out approach to storage by creating a cluster of nodes that runs adistributed file system. OneFS combines the three layers of storage architecture—filesystem, volume manager, and data protection—into a scale-out NAS cluster.Each node adds resources to the cluster. Because each node contains globallycoherent RAM, as a cluster becomes larger, it becomes faster. Meanwhile, the filesystem expands dynamically and redistributes content, which eliminates the work ofpartitioning disks and creating volumes.Nodes work as peers to spread data across the cluster. Segmenting and distributingdata—a process known as striping—not only protects data, but also enables a userconnecting to any node to take advantage of the entire cluster's performance.OneFS uses distributed software to scale data across commodity hardware. Masterdevices do not control the cluster, and slave devices do not invoke dependencies.Each node helps to control data requests, boost performance, and expand clustercapacity.Isilon node componentsAs a rack-mountable appliance, a pre-Generation 6 storage node includes thefollowing components in a 2U or 4U rack-mountable chassis with an LCD front panel:4Generation 6 Site Preparation and Planning Guide

Introduction to this guideCPUs, RAM, NVRAM, network interfaces, InfiniBand adapters, disk controllers, andstorage media. An Isilon cluster is made up of three or more nodes, up to 144. The 4Uchassis is always used for Generation 6. There are four nodes in one 4U chassis inGeneration 6, therefore a quarter chassis makes up one node.When you add a node to a pre-Generation 6 cluster, you increase the aggregate disk,cache, CPU, RAM, and network capacity. OneFS groups RAM into a single coherentcache so that a data request on a node benefits from data that is cached anywhere.NVRAM is grouped to write data with high throughput and to protect write operationsfrom power failures. As the cluster expands, spindles and CPU combine to increasethroughput, capacity, and input-output operations per second (IOPS). The minimumcluster for Generation 6 is four nodes and Generation 6 does not use NVRAM.Journals are stored in RAM and M.2 flash is used for a backup in case of node failure.There are several types of nodes, all of which can be added to a cluster to balancecapacity and performance with throughput or IOPS:NodeUse CaseGen-6 Hardware F800 and F810 (The F810 issupported with OneFS 8.1.3 only)All flash solutionGen-6 Hardware H-SeriesGen-6 Hardware A-SerieslH600, performance spinning solutionlH500, performance capacitylH400, capacity performancelA200, active archivelA2000, deep archiveS-SeriesIOPS-intensive applicationsX-SeriesHigh-concurrency and throughput-drivenworkflowsNL-SeriesNear-primary accessibility, with near-tapevalueHD-SeriesMaximum capacityThe following Dell EMC Isilon nodes improve performance:NodeFunctionA-Series Performance AcceleratorIndependent scaling for high performanceA-Series Backup AcceleratorHigh-speed and scalable backup-and-restoresolution for tape drives over Fibre ChannelconnectionsWhere to go for supportThis topic contains resources for getting answers to questions about Isilon products.Online supportlLive ChatlCreate a Service RequestGeneration 6 Site Preparation and Planning Guide5

Selecting the equipmentGrounding guidelinesTo eliminate shock hazards and facilitate the operation of circuit-protective devices,ensure that the rack is grounded.lThe rack must have an earth-ground connection as required by applicable codes.Connections such as a grounding rod or building steel provide an earth ground.lThe electrical conduits must be made of rigid metallic material that is securelyconnected or bonded to panels and electrical boxes, which provides continuousgrounding.lThe ground must have the correct low impedance to prevent buildup of voltage onequipment or exposed surfaces. Low-impedance grounding and lightningprotection are recommended.lThe electrical system must meet local and national code requirements. Local codesmight be more stringent than national codes. Floor load bearing requirements andSafety and EMI Compliance provide more information.Shock and VibrationProducts have been tested to withstand the shock and random vibration levels.
