CHAPTER 1

MediaNet Management

Overview

The MediaNet workgroup 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.

This chapter provides an overview of the tasks that you will need to

perform, the factors you should consider when configuring MediaNet,

and the tools you will use to manage your workgroup.

Topics in this chapter include:

• Management Tasks

• Configuring Your Workgroup

• Management Tools

1-2

MediaNet Management Overview

Management Tasks

As a MediaNet administrator, you are responsible for:

• Initial setup and configuration of the workgroup — You must

configure the drive set, one or more allocation groups,

workspaces, and user accounts before MediaNet can be used.

• Day-to-day administration — You will probably need to

frequently reconfigure MediaNet (for example, by creating,

deleting, or resizing workspaces; by creating and deleting user

accounts; and by changing access privileges) to accommodate new

users and evolving projects.

MediaNet also provides comprehensive monitoring functionality

that allows you to check total MediaNet activity as well as that of

each connected client.

• Troubleshooting — When problems occur with the storage

hardware, the File Manager, or a client, you will need to try and

diagnose the problem and, if possible, fix it. MediaNet provides

easy-to-understand error messages that inform you of problems in

your MediaNet workgroup as well as tools that help you diagnose

and fix problems.

Configuring Your Workgroup

Ensuring that the MediaNet workgroup is always configured to

optimize workflow in what can be a rapidly changing working

environment is the primary responsibility of a MediaNet

administrator.

This section provides information that will enable you to make the

appropriate decisions to efficiently perform this task.

1-3

Configuring Your Workgroup

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.

• How large is your drive set and does it include more than one

drive type?

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.

• 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.

The following sections provide a high-level overview of the

configuration implications of your answers to these questions.

1-4

MediaNet Management Overview

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 want to add or remove drives later.

The most important decision you must make is how many spare data

drives to allocate so that they can be rapidly swapped in for faulty

data drives. Avid recommends that you allocate at least one spare

drive for each drive size in your drive set.

For more information, see Chapter 4.

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 1-5).

• Efficiently accommodate drives of different speeds and sizes.

For more information about creating and managing allocation groups,

see Chapter 6.

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

1-5

Configuring Your Workgroup

workspace allocation to accurately meet the current needs of your

workgroup. You can reconfigure your workspaces later to

accommodate future projects or users because it is not inconvenient or

time consuming.

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

example, 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 in a multiple workspace configuration, 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 need space

later to accommodate a new project or user or to extend or protect an existing

workspace. In these situations, 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 “Data Protection” on page 1-5.

For more information about allocating and sizing workspaces, see

Chapter 7.

Data Protection

Protection is a technique that offers high levels of data integrity by

ensuring that two copies of media data are written onto different

physical drives to avoid data loss in the event of drive failure. This

allows workspaces that are protected to be repaired very quickly with

no data loss upon drive failure.

1-6

MediaNet Management Overview

The disadvantage is that protected workspaces use twice as much

space as an unprotected workspace. However, because of the data

protection and recovery speed that protection offers, Avid

recommends that you always protect your workspaces. New

workspaces are therefore protected by default unless you specify

otherwise in your preferences.

For more information, see Chapter 7.

Access Control (Users and Access Privileges)

User accounts control access to MediaNet and its workspaces. Access

privileges associated with the user account determine whether a client

user can mount a given workspace and, if so, whether the user has full

access (read/write) or read-only access to it.

To determine how you want to set up user accounts and access

privileges for your workgroup, you first need to weigh the importance

of access control against user inconvenience and administration effort

(particularly in a workgroup where users and projects frequently

change).

Once you have decided the importance of security, you can decide

upon an access control strategy that best meets your needs.

Example strategies include:

• Create a user account for each user.

This strategy offers optimum security, allowing each user access to

the appropriate workspaces regardless of the MediaNet client at

which they are working.

• Create a user account with appropriate access privileges for each

project (multiple users can use the same account simultaneously).

This strategy offers moderate security and convenience, giving users

working on each project appropriate access and requiring far less

administrative effort than individual user accounts.
