Abstract

The HP StorageWorks Modular Smart Array 500 (MSA500) offers 2-node clustering, Recovery Server, and up to 4-node shared storage support at SCSI economics, while providing high data availability with redundant controllers and multi-path I/O technology. As your storage requirements evolve and you need to expand your storage system to greater capacity or to attach more than four servers, the Modular Smart Array 500 is easily convertible to a SAN because it is based on DAS-toSAN (DtS) technology.

This “how-to” details the steps to convert a Modular Smart Array 500 to a Modular Smart Array 1000 (MSA1000) in a direct attached environment.

Introduction

The Modular Smart Array 500 (Figure 1) is an enclosure supporting 2-node clustering or shared direct attached storage at SCSI economics, while providing high data availability with redundant controllers and multi-path I/O technology. Because Modular Smart Array 500 is based on the familiar SCSI technology, there are no additional infrastructure requirements such as hubs, switches, and cables.

This allows for a low initial investment for a high availability system supporting up to 2 terabytes (TB) of data and up to four servers. As your storage requirements evolve and you want to implement a Fibre Channel solution for additional scalability such as multi-cluster functionality, the Modular Smart Array 500 is easily convertible to a SAN.

The Modular Smart Array 500 system offers DAS-to-SAN (DtS) technology, a quick-and-easy way to convert the Modular Smart Array 500 system to the HP StorageWorks Modular Smart Array 1000 when customer requirements change. Modular Smart Array 1000, built upon Smart Array technology, is the first generation 2-gigabyte (GB) Fibre Channel storage system designed for the mid-range Storage Area Network (SAN). Designed to reduce the complexity, expense, and risk of SAN deployments in a heterogeneous x86 server environment, the Modular Smart Array 1000 provides the customer a scaleable storage system with investment protection in mind.

To convert the Modular Smart Array 500 system to a SAN, customers simply remove the Modular Smart Array 500 controller(s) (Figure 2), replace them with StorageWorks Modular Smart Array 1000 controller(s), and add a Fibre Channel I/O board or Fibre Channel switchboard.

This “how-to” explains the path customers can take to migrate to a Storage Area Network (SAN). The migration procedures cover converting a base-configured Modular Smart Array 500 to a baseconfigured Modular Smart Array 1000.

Requirements

For a successful migration, you must have one Modular Smart Array 500 product directly connected to a ProLiant server running any of the following operating systems:

• Microsoft operating systems: Microsoft Windows Server 2003 Enterprise Edition, Microsoft

Windows Server 2003 Standard Edition, Microsoft Windows 2000 Server, Microsoft Windows 2000 Advanced Server, Microsoft Windows NT 4.0 Server, or Microsoft Windows NT 4.0 Enterprise Edition

• Linux operating systems: United Linux 1.0, Red Hat Linux Enterprise Server 2.1, Red Hat Linux

Advanced Server 2.1, Red Hat Linux 8.0, Red Hat Linux 7.3, or Red Hat Linux 7.2

• Novell operating systems: Novell NetWare 6.5, 6 or 5.1

Conversion from a Modular Smart Array 500 to a Modular Smart Array 1000 can only take place when:

• Both the Modular Smart Array 500 and the Modular Smart Array 1000 support the operating system.

• Available PCI slots in the ProLiant server support Fibre Channel Host Bus Adapters.

Migration procedures

The instructions in this section provide detailed information to guide you through the migration process. These procedures assume that, as a precaution, you have backed up the data on your system before removing power.

1. Power down server(s) and Modular Smart Array 500.

2. Remove the Modular Smart Array 500 controller from the front of the Modular Smart Array 500

and install the Modular Smart Array 1000 controller in its place.

Note

If only one Modular Smart Array 500 controller resides in the original system, place the Modular Smart Array 1000 controller in the same slot. If two Modular Smart Array 500 controllers reside in the system, then replace both controllers with MSA1000 controllers. Modular Smart Array 1000 requires Secure Path Software to support redundant controllers (see the StorageWorks Modular Smart Array 1000 User Guide).
