About this guide
This guide describes how the Isilon OneFS web administration interface provides access
to cluster configuration, management, and monitoring functionality.
Isilon scale-out NAS overview
The EMC Isilon scale-out NAS storage platform combines modular hardware with unified
software to harness unstructured data. Powered by the distributed OneFS operating
system, an EMC Isilon cluster delivers a scalable pool of storage with a global
namespace.
The platform's unified software provides centralized web-based and command-line
administration to manage the following features:
u
A symmetrical cluster that runs a distributed file system
u
Scale-out nodes that add capacity and performance
u
Storage options that manage files, block data, and tiering
u
Flexible data protection and high availability
u
Software modules that control costs and optimize resources

Isilon scale-out NAS

OneFS storage architecture
EMC Isilon takes a scale-out approach to storage by creating a cluster of nodes that runs
a distributed file system. OneFS combines the three layers of storage architecture—file
system, volume manager, and data protection—into a scale-out NAS cluster.
Each node adds resources to the cluster. Because each node contains globally coherent
RAM, as a cluster becomes larger, it becomes faster. Meanwhile, the file system expands
dynamically and redistributes content, which eliminates the work of partitioning disks
and creating volumes.
Nodes work as peers to spread data across the cluster. Segmenting and distributing data
—a process known as striping—not only protects data, but also enables a user
connecting to any node to take advantage of the entire cluster's performance.
OneFS uses distributed software to scale data across commodity hardware. Each node
helps control data requests, boosts performance, and expands the cluster's capacity. No
master device controls the cluster; no slaves invoke dependencies. Instead, each node
helps control data requests, boosts performance, and expands the cluster's capacity.
Isilon node components
As a rack-mountable appliance, a node includes the following components in a 2U or 4U
rack-mountable chassis with an LCD front panel: memory, CPUs, RAM, NVRAM, network
interfaces, InfiniBand adapters, disk controllers, and storage media. An Isilon cluster
comprises three or more nodes, up to 144.
When you add a node to a cluster, you increase the cluster's aggregate disk, cache, CPU,
RAM, and network capacity. OneFS groups RAM into a single coherent cache 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 operations from power failures. As
the cluster expands, spindles and CPU combine to increase throughput, capacity, and
input-output operations per second (IOPS).
EMC Isilon makes several types of nodes, all of which can be added to a cluster to
balance capacity and performance with throughput or IOPS:
Node
Use Case
-
-
S-Series IOPS-intensive applications
X-Series
High-concurrency and throughput-driven workflows
NL-Series Near-primary accessibility, with near-tape value
The following EMC Isilon nodes improve performance:
