Chapter 1 Avid Unity ISIS System Overview
System Director
The System Director is 2U in size (see “System Director Front View” on page 20) and
manages the metadata by storing directory information and file attributes. The System
Director does not store actual data, that is stored on the ISBs within the engine.
n
n
The System Director password is preset to is-admin.
You can have two System Directors configured in a redundant configuration, one Active the
other Standby. If the Active System Director goes down, the Standby System Director takes
over. You need at least one System Director to run the Avid Unity ISIS system.
n
System Directors and clients must be Time-of-day Synchronized with Clients and Servers.
The System Director provides a location to coordinate file access modes (read/write), file
locking, range locking, performance data collection, logging, file lookup, and directory
change tracking for client systems. Examples of what the System Director is able to provide
to a client or storage element are:
•Identity of all storage elements connected to the system
•Information about the ISS and IXS modules in the configuration.
•List of workspaces to include name and their unique ID number
•List of users and groups within the system
•Identity of all System Directors in the system (if you have more than one System
Director)

For true redundancy it is recommended that you connect the second System Director to a
different engine than the first System Director.
Engine
The major function of the engine, with all internal components installed, is to store the data
created during actions performed by clients that are sent through the switches.
The engine contains:
•ISBs can support either 250 GB drives or 500 GB drives providing up to
192 terabytes (TB) of storage, or 96 TB of mirrored storage. As technology advances,
the storage capacity of the drives could increase, allowing the total storage per
ISB/engine to increase.
•An ISS that allow connections for clients, a 10-Gb uplink port, an engine interconnect,
and a management port for configuration. See “Integrated Ethernet Switches” on
page 24.
•An IXS used when you have more than two engines (need an IXS for each subnet),
allowing you to connect multiple engines. See “Integrated Ethernet Switches” on
page 24.
Engine Front View
The front of the engine contains the 16 ISBs. The first is in the upper left portion of the front
and the last ISB is in the lower right.
First ISB
Fifth ISB
22
Engine Front View
Each ISB can be removed and replaced separately with the power on. If you replace an ISB
with power on, the LEDs in all of the ISBs go off momentarily. This does not represent a
problem. All functions are still active and working properly.
Engine Rear View
The following figure shows the rear of the engine in a configuration that contains the
following:
•Three power supplies (with fans)
•Integrated Switch blade (ISS)
•Integrated Expansion Switch blade (IXS)
Hardware Overview
n
Power Supplies
In a basic configuration containing two engines, each of the engines contains two ISS
modules. The IXS module is used with an ISS module in an engine only when the
configuration goes beyond two engines.
Engine Rear View
The power supplies are powered on when the power cord is plugged in; they do not have
power switches. The power supplies not only provide power, but they also contain fans that
cool the system. The system only needs two of three power supplies to supply the needed
power to function properly. You can remove and replace a power supply temporarily while
the system is running if one fails.

You should leave the failing power supply in place until you replace the failing power
supply. Replace the power supply as soon as possible to maintain the proper airflow. Do
not remove the failing supply until immediately before you replace it.
Only trained Avid technicians should remove and replace the power supply while the
system is running. Since power to the system is still applied internally to the midplane
you must always keep your hands external to the engine when a power supply is
missing from the engine.
23
Chapter 1 Avid Unity ISIS System Overview
Integrated Ethernet Switches
The two integrated Ethernet switches, ISS and IXS, serve different purposes and contain
different types of connections. You must have at least two switches in each engine for the
system to operate.
ISS Module
The connections on the ISS module are used for the following:
•Management connection — used to configure the Avid Unity ISIS engine hardware
during installation. This information is used by Avid representatives to originally
configure your system before turning it over to you.
•1-Gb (RJ-45 cable) — direct connect for clients and the System Directors.
•High speed engine interconnect (CX-4 cable) — proprietary Avid bus that connects
switch blades between engines allowing subnets to connect between the engines.
•10-Gb XFP MSA form factor transceiver (for Optical cable) — used to connect a 10-Gb
connection on a switch for connecting more clients.
w
Management
connection
Only an Avid recommended XFP transceiver should be used in the 10-Gb XFP
connection, and only Avid trained representatives should remove and replace the XFP
transceiver. Currently supported XFP are the Picolight XFP and Foundry XFP.

n
In a basic configuration containing two engines, each of the engines contains two ISS
modules. The IXS module is used with an ISS module in an engine only when the
configuration goes beyond two engines.
Client
A client uses services provided by the Avid Unity ISIS architecture. The client system, using
a 1 Gb Ethernet connection, communicates with the ISBs through the ISS to create, modify,
and read files stored in the actual ISB.
n
MediaManager clients are the only clients that have been tested with two network
connections, one to each subnet.
A client uses mechanisms specific to a Windows operating system to display, create, and
delete files within the Avid Unity ISIS media network system. For example, when viewed
from a Windows operating system, the system sees a server containing many shares that are
mapped to drive letters.
Maximum Configurations
The maximum number of clients and the maximum amount of storage available at this time
are as follows:
•Avid Unity ISIS supports up to 300 clients (150 active clients), each using dual-stream
video and up to 8 tracks of audio.
•A fully populated Avid Unity ISIS system provides up to 192 terabytes (TB) of storage,
or 96 TB of mirrored storage connected to two subnets. A maximum of 12 Avid ISIS
Engines can use either 250 GB drives or 500 GB drives.
25
Chapter 1 Avid Unity ISIS System Overview
n
A System Director must be attached to both subnets, but can only be attached once to each
subnet.
Basic Media Network Zone Configurations
The following four examples show different types of Avid Unity ISIS configurations.
Zone 1 Clients (Direct Connected)
Any client that is connected directly to an ISIS is considered a Zone 1 or direct connected
client. Each Integrated Switch Blade has a total of 8, 1Gb Ethernet ports. A single engine has
the capacity to support 16 clients or servers, subtracting any ports that are to be used by the
System Director(s). The following table defines the total number of Zone 1 ports based on
what is available by the number of engines and System Directors in the configuration.
n
Connect TransferManagers and playout AirSpeed servers to Zone 1 in Avid Unity ISIS v1.1.
You can connect the AirSpeed to Zone 2 if you are using the AirSpeed to capture.
A Zone 1 (direct connect) configuration consists group of clients connected directly to the
1-Gb connections of the ISS in the engine. The System Director also connects to the both
subnets via both ISS modules using a 1-Gb port.

Zone 2 Clients (Indirect Connect) Configuration
There is support for external switches connected through the 10-Gb port on each ISS.
Clients that are connected to an external switch are referred to as Zone 2 clients. For a list of
supported switches, search the online Knowledge Base at www.avid.com/onlinesupport.
A Zone 2 (indirect connect) configuration consists of group of clients connected to an
Ethernet switch with a 10-Gb port connected to an ISS located in the engine. The System
Director also connects to the both subnets via both ISS modules using a 1-Gb port.
Depending upon the switch configuration, each client shown connected to the external
switch is connected to one of the two subnets through one of the two 10-Gb connection.

Chapter 1 Avid Unity ISIS System Overview
As an example, the Foundry FES-X424 switch (see following illustration) is configured for
three VLANs with Gigabit (Gb) Ethernet ports 1 to 12 and 10-Gb Ethernet port 25 reserved
for VLAN 10 (default ISIS VLAN configuration). Gigabit Ethernet ports 13 to 23 and 10-Gb
port 26 are reserved for VLAN 20 (default ISIS VLAN configuration) and Gb port 24 is
reserved for the switches default VLAN. The default VLAN port is to provide uplink
capability for clients on either VLAN. Each VLAN on the Foundry FES-X424 switch is
connected to the appropriate VLAN in the media network using the 10-Gb port.

Por t 2 4
Each VLAN on the switch is allowed to support up to 12 connections but the size of the
Storage Groups and engine determine the overall client count. Changing the switch
configuration to increase the number of clients on a single VLAN is not supported and can
result in unpredictable system performance. Client count can be scaled according to the
number of available FES-X424 switches.
The following table provides possibilities of Zone 2 client counts based on the number of
ISIS engine and Foundry FES-X424 switches. For each engine listed in the table, there is an
associated Foundry FES-X424. The exception is with three engines, in which the IXS does
not provide additional ports.

The above table does not reflect the use of Zone 1 Clients (Direct Connect), which at a
minimum could consist of one System Director, AirSpeed devices, and TransferManagers.
Mixing Zone 1 and Zone 2 clients in an ISIS media network is discussed in the next section.
Hardware Overview
n
There is no current support for an external switch to be connected with the use of a 1Gb
connection as performance for multiple clients cannot be guaranteed over a single 1Gb
connection.
Zone 1 and Zone 2 Clients Mixed Configuration
The more common network configuration that is to be used in the event of Gigabit Ethernet
port limits of the ISIS Integrated Switch Blade is to combine both Zone 1 and 2 clients in the
same ISIS media network.
A mixedconfiguration (Zone 1 and Zone 2) of clients consists of group of clients
connected directly and indirectly to an engine through a switch blade. Also shown are two
System Directors that connect to the engine via two separate ISS 1-Gb ports for use as a
redundant System Director in case of a failure. Both System Directors also connect to each
other through the onboard Ethernet connections to monitor if one of the System Director
fails.
