1. Introduction

Dell™ PowerVault™ NX1950 is a unified network storage solution that simultaneously stores

both file and application data while supporting a wide range of operating environments and

communication protocols, including the iSCSI standard. The PowerVault NX1950 can be

deployed as an integrated solution (Basic and High Availability configuration) packaged with a

Dell PowerVault MD3000 Storage Array or as a Gateway connecting directly to existing Dell|EMC

SAN.

This document provides instructions to setup an NX1950 Integrated Basic Configuration to

provide iSCSI storage for usage with VMware ESX Server software. The PowerVault NX1950

integrated basic storage solution consists of single-node configuration running Microsoft®

Windows® Unified Data Storage Server (WUDSS) 2003 operating system and is pre-configured

from Dell with a PowerVault MD3000 Storage Array. Note that Dell supports only NX1950

integrated basic configuration with VMware ESX Server software storage using only the iSCSI

protocol and not NFS. Dell does not support NX1950 integrated High Availability configuration

with VMware ESX Server running on target hosts.

The Microsoft iSCSI software target functionality included as part of WUDSS uses the Windows

TCP/IP network stack on NX1950 to provide block storage services to ESX server. The Microsoft

iSCSI software target creates storage devices as iSCSI virtual disks, which are files in the virtual

hard disk (VHD) format. These iSCSI virtual disks are assigned to specific iSCSI targets. Only the

iSCSI virtual disks assigned to an iSCSI target (exported to the iSCSI target) are available to the

iSCSI initiator running as part of VMware ESX server or inside a virtual machine. This storage

can be used by ESX server to create VMFS datastores or used directly by virtual machines as

block storage. This document covers NX1950 deployment instructions using the iSCSI initiator

within VMware ESX Server and not a virtual machine. For instructions on using an iSCSI initiator

inside a virtual machine, refer to your specific initiator and guest operating system documentation.
