Getting Started

Audience

Welcome to the DS3000 Storage Manager Demo Guide.

The audience for this demo guide is technically-oriented members of the sales community who hope to understand more about how the DS3000 Storage Manager works. This guide is also for members of Field Sales wishing to use this tool to demonstrate capabilities of the DS3000 disk systems.

Background Information

The DS3000 Storage Manager Software Demo is designed for use in testing environments as a stand- alone simulator of DS3000 Storage Manager’s functions.

To prevent accidental access or corruption of critical data, the Storage Manager Demo does not have the ability to access actual storage disk systems.

Prerequisites

The Storage Manager Demo program runs on Windows 2003 or XP environments. Other environments have not been tested nor are they approved for use.

Terminology

Before we begin our journey though the DS3000 Storage Manager, there is some terminology you may not be familiar with. We will provide you with a short summary of these terms.

Array: A set of physical drives logically grouped together with an assigned RAID level. Arrays can vary in the number of drives to meet required data protection, capacity, or performance requirements (the more physical drives in an array, the higher the performance capability of the array).

FlashCopy: This feature provides the ability to create a point-in-time image of a logical drive. It is very useful for as a data source for backup applications.

Host-to-Logical-Drive-Mappings: When there are several hosts and many logical drives to associate to these hosts, Host-to-Logical-Drive-Mappings are utilized to configure a set of logical drives to each host server. We use the partitioning feature to assist in this process

Logical Drive: This is the basic storage unit that is created on the DS3000 and presented to a host server.

It is synonymous with LUN and is a drive letter (H: for example) in Windows environments.

Partition: This premium feature logically divides a single disk system into multiple systems by defining which host or host group can access each logical drive. This enables a range of hosts with different capacity, performance, or data protection demands to effectively share a single storage system.

Storage subsystem: This term will be used interchangeably with disk system. Both refer to the DS3000 series disk systems which are managed by the DS3000 Storage Manager

VolumeCopy: This feature provides the ability to create an independent copy of another logical drive or FlashCopy. This term is also used interchangeably with logical drive copy.
