DS3000 Storage Manager Software Demo Guide - 4 -
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.
