Dell DX Object Storage – File Gateway Architectural Reference

Scope of this Document

This document provides an overview of the Dell DX Object Storage CFS Gateway solution and lists the

hardware and software components that are used in the solution.

For more detailed information about deploying this solution or any of its components, see

support.dell.com.

The Dell DX Object Storage platform, initially released in May 2010, integrates applications via native

HTTP writes. The DX Object Storage Gateway solution extends access to DX Object Storage by adding a

file system interface that supports Windows & UNIX clients.

The interface is provided by CIFS/NFS software that runs on a PowerEdge R410 server. In the Gateway

solution this is called the Cluster File Server (CFS), and it provides a file system interface that enables

customers to write files to DX Object Storage as they would any other file system. The write to the DX

Object Storage system is indirect, however, as the files temporarily reside in spool cache on the CFS

server or on a shared storage device.

In a single-server Gateway solution, data objects are written to a spool that is on the CFS and then

moved to a storage node in the DX Object Storage cluster once the write is complete; in a failover

configuration, the files are written to a Dell PowerVault MD3200i storage system, which persists the

data in the event that a CFS fails. See "Specific CFS Configurations" for more details.

The following briefly describes the standard hardware components of DX Object Storage Gateway

solutions. In most cases, none of these components are yet installed at the customer site.

Cluster File Server (CFS) – This server hosts the file server software that presents the Dell DX

Object Storage system as a standard file system. In single-server solutions, this server also

provides a spool cache on local disk.

Cluster Services Node (CSN) – This node is the head of the DX Object Storage systems and

hosts the services that run on the cluster, such as cluster services, storage services, and

content router (if applicable). It is not used for data storage.

Storage Nodes – These nodes host data that is indirectly written to them by application servers

(via the spool cache). A minimum of two nodes is required, and each data object has at least

one replica.

Shared Storage System – Shared storage is a cache where files are stored before they get

written to the DX Object Storage and also where they can be accessed on subsequent reads, if

locally available. A separate shared storage system, such as the MD3200i is required for failover

solutions. In these types of solutions, if the gateway server fails over to another gateway

server, the common spool cache is still available to either write its data to the storage nodes,

or serve data to clients.
