Manual

Overview Security Features

System Features Technical Specifications

Service Features

Overview

The Dell PowerVault 735N is an easy-to-install midrange network attached storage (NAS) appliance that is

optimized to provide platform-independent storage resources to multiple servers and clients in a mixed

networked environment. The system installs directly to an existing local area network (LAN) without

disrupting other servers and requires no additional server or client software. The system uses the Microsoft®

Windows® Powered operating system and provides support for the Windows Active Directory. Additional

features include Dell ActiveArchive™ for system directory snapshots and support for Windows, UNIX®,

Novell® NetWare®, and Apple network clients.

The system also provides support for the following components and technologies:

Redundant array of independent disks (RAID) technology

Multiple LAN adapters

Disk hot-swapping

Hot spare disks

Advanced small computer serial interface (SCSI) hard-disk drives

Self-monitoring and report tool (SMART) (monitors the system for hard-disk drive failures)

File encryption

File compression

Dell ActiveArchive is a snapshot utility that allows you to create up to 250 scheduled or unscheduled

snapshots of the entire file system. You can recover deleted files and/or entire directories without accessing

your most recent full or incremental backup, which minimizes the time and effort necessary to recover

accidentally deleted files. Unlike conventional volumes where the data can change every second, snapshots

record an electronic "picture" of the data for a specific moment in time. Each snapshot is mounted as a

volume on the file system and can be scheduled through the Web user interface (UI). Once created, a

snapshot appears as a directory on the original volume. If the file system is damaged or corrupted, the

system administrator can access the snapshot directory on the root directory of each volume and restore the

file system as needed.

Storage resource management is managed and monitored through the PowerVault 735N NAS Manager, a

customized Web UI. Using a compatible Web browser, the system can be managed remotely from any client

computer attached to the network running the Windows operating system. Because the system uses the

Windows Powered operating system that is based on the same code base as Microsoft Windows 2000, any

remote management methods available on the Windows 2000 platform can also be used to manage the

system.

NOTE: The Windows Powered operating system installed in the PowerVault 735N is dedicated to file

server operations. Consequently, the PowerVault 735N cannot be used in the following capacities:

Primary Domain Controller (PDC)

Windows Internet Naming Service (WINS) server

Dynamic Host Configuration Protocol (DHCP) server

Domain Name System (DNS) server

Microsoft Exchange Server

Simple Query Language (SQL) server

Network Information Service (NIS) server

The system includes an onboard PowerEdge™ Expandable RAID Controller 2/dual channel (PERC 2/DC)

card installed in PCI slot 1. For additional storage, up to three optional PowerVault 210S storage systems

can be attached to the system using an additional PERC 2/DC card (optional) installed in peripheral

component interconnect (PCI) slot 2. The system can be attached to 10/100 or Gigabit networks, depending

on the PCI adapter(s) installed in the system.

The following sections describe the major system and servicing features of the PowerVault 735N NAS

Appliance, as well as the added security features built into the system.

System Features

The storage appliance offers the following major features:

One or two Intel® Pentium® III microprocessors with an internal operating frequency of at least 866

MHz.

Front side bus with an external bus speed of 133 MHz.

Two types of configurations: one processor with 512 MB of system memory or two processors with 1

GB of system memory. Both configurations use registered SDRAM DIMMs in the DIMM sockets on the

system board.

A flash BIOS that can be upgraded if required.

Up to five 1-inch hot-pluggable SCSI hard-disk drives.

A power supply distribution board to accommodate up to two independent power supplies.

A single, 1.44-MB 3.5-inch diskette drive.

A 24X CD-ROM drive.

The system board includes the following features:

Three full-length PCI slots, located in a removable expansion-card cage.

An integrated video graphics array (VGA)-compatible video subsystem with an ATI RAGE IIC video

controller. This video subsystem contains 4 MB synchronous dynamic random access memory

(SDRAM) video memory (nonupgradable). Maximum resolution is 1600 x 1200 with 256 colors

(noninterlaced).

NOTE: Video components are used for diagnostic purposes only.

An integrated National Semiconductor PC97317 super I/O controller that controls the bi-directional

parallel port, two serial ports, keyboard, mouse, and the diskette drive.

NOTE: The parallel port is not supported.

An integrated Intel 82559 10/100 network interface controller (NIC), providing an Ethernet interface.

A two-channel PERC 2/DC mounted on a PCI card in PCI slot 1 that supports RAID levels 0, 1, 5, 10,

and 50.

Channel A (internal channel) supports five 1-inch internal SCSI hard-disk drives using a SCSI

backplane board. The SCSI backplane board automatically configures the SCSI ID numbers and

SCSI termination on each hard drive, which simplifies drive installation.

Channel B (external channel) supports an optional PowerVault 210S external SCSI enclosure.

An integrated Adaptec AIC-7899 Ultra3 SCSI host adapter (not used in this system)

Integrated server management circuitry that monitors cooling system fan operation as well as critical

system voltages and temperatures.

System board support for the Dell OpenManage™ Remote Assistant when the optional Dell

OpenManage Remote Assistant Card 2 (DRAC 2) is installed, providing additional local and remote

server management.

A PS/2-style keyboard port, dual USB ports, and a PS/2-compatible mouse port.

NOTE: The keyboard and mouse are used for diagnostic purposes only.

The following software is included with the system:

The System Setup program for quickly viewing and changing the system configuration information.

Diagnostics for evaluating the system's components and devices.

NOTE: For information on using the system diagnostics, see "Running the Dell

Diagnostics."

Service Features

The storage system includes the following service features to make troubleshooting and repair easy and

effective, in most cases without tools or service aids:

Dell Diagnostics, which checks the system's hardware and all major system components without any

additional equipment and without destroying any data (if the system can boot)

Embedded server management hardware, which monitors temperatures and voltages throughout the

system and notifies you if the system overheats, if a system cooling fan malfunctions, or if a power

supply fails

Redundant, hot-pluggable power supplies

Redundant, hot-pluggable RAID hard-disk drives

The system chassis design simplifies removing and replacing system components. You can replace

microprocessors or DIMMs without removing the system board. The Dell-designed SCSI backplane board

and hard-disk drive carriers eliminate the extensive cabling and hard-disk drive configuration usually

required for a SCSI subsystem.

Security Features

The storage system also provides the following security features:

Security support for Windows 2000 Active Directory, Windows NT® Domain and Novell Directory

Services (NDS)

Chassis intrusion sensor that generates an event to the event log when the chassis is opened

System status light that changes to amber while chassis is open

Built-in chassis lock that prohibits unwanted users from accessing the inside of the chassis
