Simplified SAN storage for IBM

_` xSeries and

BladeCenter systems

IBM TotalStorage DS300

Flexible, low cost SAN storage

The IBM TotalStorage® DS300 is an entry-level, low cost workgroup storage subsystem for IBM _` xSeries and BladeCenter™ servers. Designed to deliver advanced functionality at a breakthrough price, the DS300 offers an exceptional solution for workgroup storage applications, such as file, print and Web serving, as well as remote boot storage for diskless servers.

Highlights

■ Designed to provide a costeffective Internet SCSI (iSCSI) subsystem for workgroup storage applications, such as file, print and Web serving, as well as remote boot for diskless servers

■ Leverages standard Ethernet infrastructure to help offer a simple, affordable storage area network (SAN) solution—with single- and dual-controller configurations

■ Includes easy-to-use IBM®

ServeRAID™ Manager, which provides common management software

■

■

Helps deliver business continuance and disaster recovery through enterprise-class software features

Scales to 2TB of physical storage capacity

Leveraging standard Ethernet infrastructure and low cost SCSI drives, the

DS300 is designed to offer a simple, affordable storage area network (SAN) solution that can be used in directattached or network-attached environments for shared storage. For even greater flexibility, the DS300 is designed to allow simultaneous support of heterogeneous operating system (OS) environments for xSeries and

BladeCenter servers—in either singleor dual-controller configurations.

■ Uses common IBM _`®

xSeries® Ultra320 SCSI disks

Performance for today, scalability for tomorrow

By utilizing standard xSeries hot-swap

Ultra320 SCSI drives, designed to offer high performance and reliability, the

DS300 can help your business achieve enterprise-class, high I/O processor

(IOP) performance today—and allow for future growth tomorrow. The modular design of the DS300 is designed to allow you to easily perform upgrades and additions to help meet the needs of your growing, changing application environment—scaling to support increasing volumes of data flexibly and affordably.

In addition, advanced software features on the DS300—including access control lists (ACLs) and online array expansion—are designed to give administrators the power to configure storage according to changing usage needs. These features also help enable

IT managers to share storage across multiple application servers.

Enterprise-class reliability and availability

The new DS300 is designed to deliver advanced functionality for business continuance and disaster recovery—at an entry-level price. Using a rackmountable 3U enclosure with 14 SCSI drives and redundant design, hot-swap power and cooling modules, the DS300 features RAID reliability and highavailability software to help maintain operations.

The enclosure supports either one or two controllers for high-availability configurations. Each controller is designed to support up to three Gigabit Ethernet ports for management and redundant data paths so that—even if a line or a controller fails—multiple paths between servers and storage can help maintain a connection.

Powerful management tools

The DS300 is designed to offer excellent storage management and configuration capabilities through

IBM ServeRAID Manager, helping enable clients to manage multiple

IBM TotalStorage DS300 and

DS400 subsystems—as well as directattached internal ServeRAID controllers—all through a single, easyto-use management console with an extensive online help library.

Configuration wizards simplify initial storage setup. IBM ServeRAID Manager is designed to support most common operating environments for workgroup applications, including Microsoft

Windows®, Novell NetWare and

Linux® platforms.

Metro mirroring 1 on the DS300 is designed to enable disaster recovery implementations to help protect critical data. The DS300 also offers optional advanced features such as spaceefficient IBM FlashCopy® solutions, which are designed to help reduce storage backup windows and improve storage utilization for Microsoft®

Exchange, Microsoft SQL Server™

2000 and Lotus Notes® applications.

The management software of the

DS300 is built directly into the client/server workgroup manager IBM

Director 1 . IBM Director is designed to allow IT administrators to view and track the hardware configuration of remote systems in detail and monitor the usage and performance of critical components, such as processors, disks and memory.
