CHAPTER 1

Introduction

Avid Unity MediaNet is a high-performance distributed file system

that provides high-capacity shared media storage for a number of

connected Avid systems.

This chapter describes:

• Avid Unity MediaNet Environment Overview

• Avid Unity MediaNet Configuration Overview

• Tasks and Tools

• The MediaNet Setup Manager

• The Administration Tool

• The Monitor Tool

14

Avid Unity MediaNet Environment Overview

The MediaNet environment consists of:

• MediaNet clients — Avid systems enabled to use the MediaNet

file system.

• Fibre Channel network — High-bandwidth network technology

that supports the high throughput required to allow multiple

users to share video and audio simultaneously. A Fibre Channel

switch provides the backbone of the network.

• Shared Fibre Channel drives — A collection of fibre channel

drives enclosed in one or more rack-mountable MEDIArray

™

enclosures and managed as a single virtual unit by the MediaNet

File Manager service on the MediaNet Server.

• MediaNet Server — A Windows NT

®

server on which the

MediaNet File Manager that controls the MediaNet file system

runs.

Together, these components enable up to nine client workstations to

MediaNet Storage Architecture

MediaNet simplifies the management of your storage hardware by

combining all of your physical data drives into a drive set that provides

a single, large file system. To use the MediaNet file system, you must

first assign all data drives in the drive set into allocation groups that are

individually managed file system partitions that span multiple

physical drives. Although you can assign all of your data drives to a

single allocation group, performance considerations might require you

to divide your drives into multiple allocation groups.

Allocation groups can be divided, according to your particular needs

at any given time, into one or more dynamically resizable virtual

volumes, or workspaces. These workspaces are the MediaNet elements

that are made available for mounting on client workstations (the drive

set and allocation groups are transparent to client users).

Access to MediaNet is controlled by allocating user accounts with read

access, write access, or both to each workspace. Data integrity can be

ensured by optionally protecting workspaces. Protection involves a

redundant configuration in which files written to protected

workspaces are duplicated on more than one drive. This allows a

protected workspace to be quickly repaired with no data loss after a

drive fails.

A summary of the MediaNet storage architecture follows:

• The MediaNet storage hardware is managed as a drive set that

forms the core of the MediaNet file system. Physically, the drive

set comprises a number of different types of drives:

- Administration drive — A special drive that facilitates

communication about the MediaNet file system between

client workstations and the MediaNet File Manager.

- Data drives — Contain the media data that client

workstations store and access on the drive set.

- Spare drives — Spare drives can be quickly swapped for bad

data drives in the event of failure.

• The data drives in the drive set are assigned into one or more file

system partitions called allocation groups.

• Each allocation group is subdivided and managed as an unlimited

number of virtual workspaces. Each workspace has a set of

characteristics that you can change at any time:

- Size — Each workspace can be set to any size such that the

sum of the sizes of all the workspaces does not exceed the total

size of the allocation group.

- Protection — If active, media files written to the workspace

are duplicated on different physical drives to avoid data loss

in the event of drive failure. A protected workspace uses twice

as much storage space as an unprotected workspace.

- Access privileges — Determine whether users can mount,

read, or read and write to a workspace.

MediaNet from the User’s Perspective

MediaNet client users mount MediaNet workspaces on their

workstations (requiring a user account to do so). Once mounted,

workspaces behave like local media drives that can be accessed by

others working on the same project. If properly configured, this allows

several users to access the same media and to start using it

immediately after it has been created.

Avid Unity MediaNet Configuration Overview

The MediaNet environment allows you to centrally manage very large

amounts of storage that multiple MediaNet clients can access to share

video, audio, and effects media in an intuitive, collaborative

workgroup. As administrator, it is your job to make sure that

MediaNet is always configured to optimize workflow in what can be a

rapidly changing working environment.

Overall Considerations

The following strategic considerations will determine your priorities

when making configuration decisions and trade-offs (possibly

impacting more than one aspect of your configuration):

• What is your site type?

In-house and rental editing suites will probably require very

different administration requirements, particularly in terms of

workspace access restrictions and how often you need to

reconfigure workspaces and users.

• Does your workgroup include dual-stream uncompressed clients?

If so, you will need to set up special hardware and allocation

group configurations.

18

• How large is your drive set and what kinds of clients do you need

to support?

If your drive set is very large, or has different drive types, you will

probably need to assign your data drives to more than one

allocation group to optimize performance.

• Will your client users be working on individual projects with their

own media or will they be collaborating on team projects that use

the same source media?

These factors affect how you should allocate workspaces and user

accounts.

• Is security or ease of access more important at your site?

Individual password user accounts combined with tightly

controlled workspace access privileges provide the most security

at the cost of restricting user flexibility.

• Which is more important at your site: the integrity and speed at

which your media can be recovered in the event of hardware

failure or maximizing available storage space?

These factors determine whether you will want to protect your

workspaces.

The following sections provide a high-level overview of the

configuration implications of your answers to these questions.

Setting Up and Managing Your Drive Hardware

Setting up your hardware to create a drive set is very straightforward

and should only need to be done during the initial setup of your

MediaNet installation, unless you later want to add or remove drives.

The most important decisions you must make are which drive to

allocate an administration drive and whether you want to allocate

spare data drives so that they can be rapidly swapped in for faulty

data drives.

For more information, see Chapter 2

.

Assigning Drives to Allocation Groups

MediaNet requires you to assign the data drives in your drive set that

you want to be available as storage to one or more allocation groups.

Because MediaNet handles the drives in each allocation group as a

separate unit, creating multiple allocation groups allows you to:

• Support dual-stream uncompressed clients (also requires a special

hardware configuration).

• Break up very large drive sets into smaller units that reduce the

scope of data loss in the event of a drive failure in an unprotected

environment (see “Data Protection” on page 22

).

• Efficiently accommodate drives of different speeds and sizes.

Creating and Sizing Workspaces

Because workspaces are virtual rather than physical partitions, they

are very easy to create, resize dynamically, and delete to accommodate

your environment’s needs. This flexibility allows you to tailor your

workspace allocation to accurately meet the needs of your

environment now — reconfiguring your workspaces later to

accommodate future projects or users is not inconvenient or time

consuming.

First, you must consider how you want to allocate workspaces. Do you

want to allocate them to accommodate projects, teams, individual

users, or a combination of one or more of these?

Once you have determined how you plan to allocate workspaces,

you’ll need to determine how much storage each workspace will

require (a function of media duration and, for video, resolution) and

allocate space accordingly.

n

When sizing workspaces, you should consider reserving some space rather

than assigning all of it immediately. Once space is allocated, it tends to be

filled quickly and you might later need space to accommodate a new project or

user or to extend or protect an existing workspace. In such a situation, it

tends to be much easier to use space held in reserve than to take it away from

an existing workspace.

When allocating and sizing workspaces, you should also consider

whether access restrictions are required and whether protection for

data integrity is necessary for each workspace. For more information,

see “Access Control (Users and Access Privileges)” on page 21

and

“Data Protection” on page 22
