on page 35).
•Create a storage group (see “Configuring and Managing Storage” on page 67).
•Create a workspace (see “Managing Workspaces” on page 81).
•Create user accounts (see “Managing Client Accounts and Access Privileges” on page
107).

2Configuring Your Avid Unity ISIS
Software
Avid Unity ISIS allows you to manage very large amounts of storage that multiple clients
can access to share video, audio, and effects media in an intuitive, collaborative
environment.
This section provides an overview of the configuration factors you need to consider, the
tasks you need to perform, and the tool you use to manage storage groups, clients, and
workspaces.
For more information, see the following topics:
•Management Tasks and General Considerations
•System Capacity
•Using the Administration Tool
•Understanding the Administration Tool Interface
Management Tasks and General Considerations
The responsibilities of an administrator include the following:
•Initial setup and configuration of the workgroup: You must configure the storage
elements, as well as one or more storage groups, workspaces, and user accounts.
•Day-to-day administration: You probably need to reconfigure your network to
accommodate new users and evolving projects.
Avid Unity ISIS also provides monitoring functionality that allows you to check total
system activity as well as that of each connected client.
•Troubleshooting: When problems occur with the storage hardware, the System Director,
or a client, you need to diagnose the problem and, if possible, fix it. Avid
provides easy-to-understand error, warning, and informational messages that inform you
of problems, as well as tools that help you diagnose and fix problems.
Unity ISIS
2 Configuring Your Avid Unity ISIS Software
How you answer the following strategic questions determines your priorities when making
configuration decisions and trade-offs (possibly affecting several aspects of your
configuration).
•What is your site type?
Broadcast and post-production editing suites, for instance, require very different
administration requirements, particularly in terms of workspace-access restrictions and
how often you need to reconfigure workspaces and users. For more information on
managing workspaces, see
•Does your workgroup include uncompressed clients, multiple-stream clients, or high
definition clients?
If so, you will need to set up special hardware and storage group configurations. For
more information on managing storage groups, see
Storage” on page 67.
•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. For more
information on managing users and user groups, see
Access Privileges” on page 107.
•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?
“Managing Workspaces” on page 81.
“Configuring and Managing
“Managing Client Accounts and
Avid recommends that you always use protection to avoid data loss. However, these
factors determine whether you will want to protect your workspaces.
•Is security more important than ease of access 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. For more
information on managing user accounts and access privileges, see
Accounts and Access Privileges” on page 107.
System Capacity
An Avid Unity ISIS media network provides up to 192 terabytes (TB) of storage, or 96 TB
of mirrored storage, distributed across storage elements

The System Director handles file management for the system, which supports a
configuration including the following:
•2,500,000 to 3,000,000 files; however, the maximum number of files depends on the
number of directories, the number of files in directories, the number of System
Directors, and the length of file names
•Up to 10,000 files in a directory and 10,000 directories, although individual client
accounts might require restrictions on files and directories based on performance issues
•Up to 1000 user accounts
•Up to 550 Windows and Macintosh clients with mounted workspaces; the total amount

Using the Administration Tool
You use the Avid Unity ISIS System Administration tool for the configuration and
day-to-day administration of workspaces, clients, and storage groups. The tool also allows
you to monitor your system’s activity.
To use the Administration tool, you need to have Macromedia® Flash® Player installed on

2 Configuring Your Avid Unity ISIS Software
Before Performing Administrative Functions
It is critical that clients unmount workspaces when you do the following:
•Stopping and restarting the System Director (unmount all workspaces)
•Rebooting the System Director (unmount all workspaces)
•Changing users’ or user groups’ access (unmount only the affected workspaces)
c
If a client is using a workspace when it is taken offline, the connection to the workspace
is broken and data might be lost.
Opening the Administration Tool
The Administration tool runs as a Web service on the System Director. This allows you to
open the Administration tool from any system that has an Ethernet connection to the System
Director, as well as from the System Director itself.
c
Performing administrative functions on more than one Administration tool at the same
time can cause unexpected results. For example, if two administrators are deleting the
same user account at the same time, a second user account might also be accidentally
deleted.
When you start the Administration tool, the Login dialog box opens. If you have specified an
administration password (see
Administration tool prompts you to supply that password to log in. If you type the wrong
password, an error message appears and the Login dialog box reappears.
When you first install the Avid Unity ISIS software, the login password is blank by default.

3 Managing the Storage Hardware
Rectifying Files
Once you have added storage elements to your network and configured them for storage, the
storage elements
stored files, cleaning up deleted files and verifying existing files. This process, called
“rectifying files,” allows the ISBs to communicate with the System Director to monitor the
state of its storage and clean up any files that the ISB no longer needs to store. Rectifying
files occurs randomly and asynchronously during normal system operation to minimize any
potential decrease in system performance. The process is indicated for each affected ISB in
the Status column in the Storage Elements list.
Storage elements also rectify files when the ISB starts or restarts. When this happens — for
example, when an ISB loses connectivity to the network
be in sync with the data in the file system itself. Also, if a client, such as the asset manager,
cannot communicate with the ISB, there might appear to be more data allocated to the ISB
than the file system has allocated. To correct this, you can manually send the storage element
a command to rectify its files.
You can also use the Issue Command button to clear all Network Degraded status messages

Removing Storage Elements from the File System
When you remove storage elements from the Avid Unity ISIS file system, or when you
move storage elements from one system to another, you need to unlink the storage elements
from the file system.
You cannot remove a storage element that is part of a storage group. You must remove the
n
storage element from its storage group first so the system can redistribute data before
unlinking the storage element from the file system.
Avid strongly recommends that you wait until any redistribution process completes before
removing storage elements.
To remove a storage element from the ISIS file system:
1. Open the Administration tool. (For information on opening the Administration tool, see
“Opening the Administration Tool” on page 24.)
2. Select Storage Groups from the list on the left.

10. Click Apply.
Removing Storage Elements from the Media
Network
You can remove and replace storage elements without stopping the System Director or
turning off other components of the network. There are two principal reasons for removing
storage elements from the system:
•The element has a high number of unrecoverable errors
•The element has failed or has been removed from the system
Before you remove an Avid Unity ISIS Storage Blade (ISB) from the network, you must
redistribute the data stored on the ISB to other ISBs in the system. The redistribution occurs
before you physically remove the ISB, and the process entails moving data to the remaining
drives within the storage group. Once you redistribute the data, you add a new ISB to the
system and then perform a redistribution again to place data onto the new ISB.
c
If you physically remove an ISB from the media network before redistribution is
complete, data loss can occur.
You should maintain an unused block of storage equivalent to one ISB within the storage
n
group to allow redistribution from a failing ISB to other ISBs within the group.
49
3 Managing the Storage Hardware
If possible, you should redistribute data while the drive is experiencing problems but has not
yet been removed from the system. This allows the ISB having problems to participate in the
redistribution process by offering data that it has to both clients and to other ISBs.
Often the ISB is still functional, but its performance is slightly degraded — for example, the
n
ISB might have an unrecoverable error on one of its disks, or it might have long I/O times.
If the ISB fails, or if it has been removed from the system, you can perform a redistribution
from the mirrored locations associated with the ISB. However, if any other mirrored location
experiences a failure while performing a redistribution, the system can lose data.
Consider the following when planning a redistribution:
•A one-to-one replacement of ISBs might leave you with less storage space in the storage
group than you require. Instead, plan for using more ISBs than you need for storage and
bandwidth for each storage group. This way, you can keep an optimal amount of
available storage space allocated to the storage group. This allows you to quickly
perform redistribution, rather than attempting a redistribution with only one spare ISB.
•In general, the removal of an ISB is quicker than an addition. This is because all of the
other ISBs in a storage group participate in redistribution by moving a copy of any block
held by the element to another location. The more ISBs in the storage group, the more
the workload is shared. A single ISB addition is slower than a removal because the ISB
receiving the data acts as a limiting factor for the redistribution.
50
•When you add a new ISB to the Avid Unity ISIS file system and then add it to a storage
group, the system redistributes data from the existing drives in the storage group to the
new element. This redistribution maintains all previously stored data, but the data might
not reside on the same storage elements.
If you do not have a replacement for a failed or failing ISB, Avid recommends that you leave
n
it in the system. Proper airflow can be disturbed if an ISB slot is left open.
The following steps list the actions necessary for removing a storage element:
1. Identify the storage element you want to replace.
2. Remove the storage element from the storage group.
3. View the status of the redistribution and wait for redistribution to finish.
4. Remove the storage element from the file system.
5. Physically remove and replace the storage element.
6. Add new storage element to the file system.
7. Add the new storage element to a storage group.

Managing Storage Groups
Storage groups are partitions, each containing multiple assigned storage elements. This
section describes how to create and manage storage groups in your network.
For more information on managing storage groups, see the following topics:
•“Storage Group Usage Guidelines” on page 72
•“Creating Storage Groups” on page 73
•“Adding Storage Elements to Storage Groups” on page 75
•“Removing Storage Elements from Storage Groups” on page 76
•“Adding Storage Elements from Another Storage Group” on page 78
•“Adding Storage Elements Previously Used with Another Network” on page 79
•“Deleting Storage Groups” on page 80
Storage Group Usage Guidelines
You can assign all of your storage elements to one large storage group, or you can divide
your storage elements among multiple storage groups. (Storage elements can be assigned to
only one storage group.) To optimize performance, you can use storage groups to configure
your Avid
72
Unity ISIS file system.
Managing Storage Groups
Avid recommends that you use all storage elements in an Avid ISIS Engine when creating a
storage group, and you size larger storage groups in increments of whole ISIS engines.
While storage groups can be created with a partial ISIS engine, performance and sizing
scalability cannot be guaranteed.
You can divide very large storage groups (over 60 storage elements) into several storage
n
groups to minimize the risk of two storage elements used in a protected workspace failing at
the same time. When you assign storage elements to different storage groups, however, you
must be careful how you allocate bandwidth reservations for the different groups as the
available bandwidth allocations for individual storage groups might differ from the total
system bandwidth, depending on the number of storage elements assigned to each group.
If your environment supports clients with very high bandwidth requirements, you need to set
up specific hardware and storage group configurations to support them. For more
information, see the Avid
In such an environment, you can use storage groups to isolate clients that need very high
bandwidth and thus eliminate the competition from other clients trying to access the same
storage elements. For example, when high-definition (HD) media is in its own storage group
and a single client is using the HD media, that client is serviced independently from any
other clients in the workgroup. This logic can also be applied to separating audio and video
media.
Unity ISIS Setup Guide.
In other situations, storage groups are more flexible, allowing you to assign storage elements
in your file system configuration to storage groups with few limitations.
You must use a minimum of one storage element per storage group.
n
Creating Storage Groups
A storage group is a set of physical storage elements that store a subset of the complete set
of media files accessible within a shared storage environment and which can accommodate
different storage element types, as well as clients with different privileges and media
requirements (for instance, clients that use low-resolution media and ones that use
high-resolution media).
If you have bound storage elements to the ISIS file system but you have not created any
n
storage groups, the Create Storage Groups dialog box opens by default when you select the
Storage Groups list.
To create a new storage group:
1. Open the Administration tool. (For information on opening the Administration tool, see
“Opening the Administration Tool” on page 24.)
2. Select Storage Groups from the list on the left.

Removing Storage Elements from Storage Groups
You can remove storage elements from your storage group, as long as the following
conditions are met after you have done so:
•The storage group contains at least four storage elements.
•The storage group contains enough storage elements to support the space allocated to
your workspaces.
76
This is the total amount of storage allocated to the workspaces, not the actual amount of

5Managing Workspaces
Workspaces are virtual volumes that exist on storage groups and can be resized dynamically.
Workspaces allow you to segment your storage elements easily to accommodate projects and
users.
This section describes how to create, rename, and delete workspaces. It also tells you how to
manipulate the amount of storage allocated to each workspace, how to move a workspace
and its contents to another storage group, and how to protect a workspace against drive
failure.

Allocating Workspaces
Before you create workspaces, you should consider how you want to allocate them. For
example, do you want to allocate them to accommodate projects, groups, individual clients,
streaming bit rates, media types, media distributors, or a combination of these?
Once you create a plan to allocate workspaces, you’ll need to determine how much storage
each workspace requires and allocate space accordingly. This might be a function of project
size or the number of clients, or it might be a function of media duration or media resolution.
5 Managing Workspaces
For instance, if you plan to capture high-definition (HD) media to a workspace, you need to
create a workspace with more than two storage elements. (Assigning a full chassis of storage
elements to an HD workspace would perform better in this example.)
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
client or to extend or protect an existing workspace. In these situations, it is 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.
Accessing the Workspaces Dialog Box
You perform workspace functions in the Workspaces dialog box of the Administration tool,
which allows you to do the following:
•Create, delete, and rename workspaces
•Manipulate the amount of storage allocated to each workspace
82
•Protect a workspace against drive failure by duplicating files on more than one drive (a
form of mirroring)
•Monitor how much free space exists on each workspace, and how much unallocated
space exists in each storage group
•Move a workspace and its contents to another storage group
To open the Workspaces dialog box:
1. Open the Administration tool. (For information on opening the Administration tool, see
“Opening the Administration Tool” on page 24.)
2. Select Workspaces from the list on the left.

5 Managing Workspaces
Protecting Workspaces
The Protection option 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.
The disadvantage is that protected workspaces use twice as much space as unprotected
workspaces. However, because of the data protection and recovery speed that protection
offers, Avid recommends that you always protect your workspaces.
Workspace Protection Recommendations
Because of the potential impact of a drive failure, Avid recommends protecting all your
workspaces whenever possible. If you want to ensure protection of your files at all times,
always enable the Protection option when creating new workspaces (before any files are
stored on the workspace).
If you are not sure that all files on a given workspace are protected, select the workspace and
enable the Protection option for the workspace. This protects all new files added to the
workspace, and adds protection to any existing files in the workspace that are not already
protected.
94
Avid Unity ISIS allows clients to access protected workspaces that have more than one
storage element missing from the workspace’s storage group. However, protected storage
groups with more than one storage element missing are unstable. Some or all of the files the
storage groups contain might not be available for use. The administrator should repair these
workspaces at the earliest opportunity.
When you are deciding to use protection, Avid recommends you consider the following:
•Storage groups with an even number of storage elements provide the best performance
and the best data distribution for all video resolutions.
•Storage groups with an odd number of storage elements might not provide adequate
performance for some video resolutions, such as 1:1 or 2:1.
•If you are not going to protect a workspace, the storage group can contain any number
of storage elements.
Setting Workspace Protection
You can use the Workspaces dialog box to enable or disable workspace protection.
To enable protection for a workspace:
1. Open the Administration tool. (For information on opening the Administration tool, see
“Opening the Administration Tool” on page 24.)
2. Select Workspaces from the list on the left.

3. Click the Apply button.
Redistributing Data
Redistribution is an operation that ensures all files on a workspace are balanced evenly
across the storage elements in the storage group to provide optimal file system performance.
Data chunks are distributed across multiple storage elements to ensure redundancy and
protect against data loss. Redistribution occurs automatically in the following
circumstances:
•Adding a storage element to a storage group
•Removing a storage element from a storage group
•Moving a workspace from one storage group to another
•Removing protection from a protected workspace
•Protecting an unprotected workspace
You can also initiate a manual redistribution of data.
Redistribution Guidelines
You can start a redistribution when a workspace is in a load or a no load condition:
•A load condition occurs when the workspace has active clients (clients reading and
writing to the workspace).
•A no load condition occurs when a workspace has inactive clients (clients that have the
workspace mounted but are not performing reads or writes).
Whenever you perform a redistribution, you should observe the following guidelines:
•When redistributing under load, allow the redistribution to complete before initiating a
second redistribution.
96
Redistributing Data
•System performance can degrade up to 20% during redistribution in a workspace with
maximum client count. Reducing the number of clients by 20% allows the active clients
using the workspace to function normally, with successful playback and captures.
Reducing the overall load by 20% of the maximum capacity might be needed in the
event of client performance degradation.
•The amount of time a redistribution takes varies depending on whether the workspace is
in a load or a no load condition, whether you add or remove an ISB, and how much data
in the storage group must be redistributed. For more information on redistribution times,
see the Avid
•Do not physically remove an storage element until it has been removed from the storage
group, the redistribution is complete, and it has been removed from the file system.
Unity ISIS ReadMe.
c
If you physically remove an storage element from the media network before
redistribution is complete, or if you physically remove more that one storage element
from a storage group before performing a redistribution, data loss can occur.
Limitations on expected client performance during redistribution include the following:
•Reducing audio tracks from 8 to 4 during playback might be required during
redistribution. (Normal operation supports 2
•Reducing the number of video streams from 2 to 1 might be required during
redistribution. (Normal operation supports 2 streams of video.)
Performing a Full Redistribution
In addition to automatic redistribution operations (see “Redistributing Data” on page 96),
redistribution can also be invoked manually. The most common situation where you need to
perform a full redistribution is when the Config Changes count exceeds 10. (For information
about Config Changes, see
When the Config Changes count reaches 10, a message warns you to perform a

When redistributing files manually, you should apply the redistribution to all workspaces.
Avid does not recommend performing a full redistribution on some workspaces and not on
others.

n
Use of the Resume Redistribution and the Suspend Redistribution options can result in
degraded system performance. Suspending redistributions can have serious
consequences for the file system if not monitored closely. These two Advanced
Commands options should be used by Avid Customer Support personnel or under Avid
Customer Support direction.
You can also use the Advanced Commands to verify a redistribution. Verification checks that
all bad blocks on the appropriate storage element have been deleted and that the
redistribution has completed successfully. You should use the Verify Redistribution
command whenever storage elements are rebooted following a redistribution
example, after you upgrade your system. In this case, storage elements might report a
“Repairing Mirrors” status on reboot; verifying the redistribution replays the redistribution
operation using the current configuration and restores the status to normal.
Verification causes minimal impact on performance and completes quickly.
