Overview
The MediaStream Networked Storage System is the latest generation of Avid MediaStream
Servers (MSS). The Avid MediaStream family of servers was first introduced in 1992 as part
of Hewlett Packard’s Video Communications Division that pioneered MPEG2-based
broadcast-quality video servers. Avid MediaStream acquired the Video Communication
Division in 1999, and has continued innovative developments. The Avid MediaStream
Networked Storage System builds on the legacy MediaStream and supports all current and
future video I/O hardware.
Page 26
Chapter 1 Introduction
The Avid MediaStream Server Networked Storage System is based on the existing
MSS Servers with the addition of the following key features and benefits:
•Centralized storage—All MSS Networked Storage server nodes belonging to a
networked storage cluster have access to a common pool of storage. In this model, one
server node can be used for ingesting video material while other nodes play the ingested
material back within seconds of the start of the record process.
•Simplified automation—Since the need to copy video material is eliminated within a
storage cluster, media management is dramatically simplified. An entire Networked
Storage Cluster is viewed by automation as a single server, eliminating the need for
complicated schedule driven heuristics and algorithms to ensure that playout material is
available at the right server.
•Fully backwards compatible—The MSS Networked Storage System is fully compatible
with standalone MSS servers, and files can be shared between existing MSS servers and
the MSS Networked Storage server nodes.
•No single point of failure—All common storage and common file system components
are fully redundant and transparently fail-over in real-time.
•Hot swap of redundant components—All redundant components can be exchanged in
case of failure while the system is operational.
•Hot expandable—You can expand storage capacity and channel count while the system
is on-air.
Major Components
Three major components make up the MSS Network Storage System:
•MSS Networked Storage File System
•MSS Networked Storage System server nodes
•Palladium 1000 storage system
Networked Storage File System
The Networked Storage File System maintains a database of the location of clips on the
Palladium Store 1000 storage system. It runs on two fully redundant Windows 2000
computers called File System Controllers (FSC) as shown in the following figure. The
Networked File System software automatically mirrors File System changes on one FSC
onto the redundant FSC in real-time. In case of a FSC failure, or any connection failure
between a video server node and the FSC (including an Ethernet switch failure), the server
nodes can continue to access the Networked Storage File System without interruption via the
redundant Ethernet control path.
26
Page 27
Major Components
File System Controller
Each FSC is linked via a VLAN (Virtual Local Area Network) Ethernet topology through its
own VLAN switch to the MSS Networked Storage System server nodes. This further
enhances network isolation and prevents network loops from causing potential additional
latencies in the network if a failure occurs in the Ethernet topology itself. The MSS
Networked Storage System requires two FSCs regardless of the size of the system. This
important feature contributes to the system’s ability to handle real-time fail-over scenarios.
VLAN Switch
MSS 8000 Server Nodes
The video input/output (I/O) portion of the MSS Networked Storage System is the
MediaStream 8000 server nodes. Server nodes provide the video engine of the system. The
MediaStream 8000 chassis incorporates nine video I/O slots in a 5 rack unit (RU) package.
The MSS 8000 is based on proven MediaStream 700/1600 platform technology.
MS Server 8000
27
Page 28
Chapter 1 Introduction
Each server node has redundant connections to both FSCs through redundant VLAN
switches. In addition, communication to the storage system is via Fibre Channel connections
to redundant controllers in the storage system. This design provides for dual data paths and
fast fail-over should key components or connection paths fail (see “MSS Networked Storage
System Configuration” on page 31).
As with existing MSS systems, each server node contains its own System Controller board,
redundant power supplies, fans, and a combination of encoder and decoder boards. In
general, decoder boards play content out to broadcast, while encoder boards convert
601 Serial Digital to MPEG-2 for storage on the system.
An individual server node can provide up to 16 channels. One MSS Networked Storage
System can accommodate up to 16 server nodes. This system is referred to as a cluster. An
expanded system can support up to 16 clusters that can share data through an FTP gateway
server node.
The server node interfaces with the station’s automation system via RS-422 protocol and
Ethernet .dll and sends the video content in specified formats to the station’s routing system.
VME Bus
The System Controller board and other control boards plug directly into a VME backplane
(bus). The System Controller board controls traffic on the backplane, while direct processing
power is distributed among encoders, decoders, and the other boards plugged into the VME
bus. Data flow between the array controller and input/output cards travels down the back
plane of the bus.
LynxOS™ Operating System
The server nodes run under the LynxOS, a real-time variant of the industry-standard UNIX
operating system. LynxOS provides a stable platform for reliable real-time playout and
record of video with a low risk of system interruption.
AMS
AMS is the primary server node application that provides interface and control with
automation.
28
Page 29
Palladium Store 1000
The Palladium Store 1000 storage system consists of one or more storage units. Each
Palladium Store 1000 chassis contains dual RAID controllers and 10 disks in two redundant
4+1 sets.
In case of a single disk failure in either or both of the disk sets, the system continues to
operate normally at full performance. After replacing the faulty disk, the system can
reconstruct the data from parity while operating at full performance.
Palladium Store 1000 - Front Bezel
MSS Networked Storage System Features
Each controller provides a separate data path to the server nodes. In case of a component
failure, the system will continue to operate normally. Hardware replacement of the failed
component can occur without service interruption.
MSS Networked Storage System Features
File System Redundancy
The MSS Networked Storage System is able to sustain a failure in any file system control
component without performance degradation, video loss, or jitter. The redundant
MediaStream Networked Storage File System control path consists of the following three
components:
•Two redundant FSCs that are independent from each other in software and hardware,
and which mirror the FSC File System in real-time.
29
Page 30
Chapter 1 Introduction
•Two redundant VLAN Ethernet switches, which are independent of each other in
functionality. These switches provide isolated connections between the video server
nodes and the two FSCs. The VLAN topology design prevents network loop conditions
that could lead to unacceptably long network time-out scenarios during an Ethernet
LAN connection failure.
•Two redundant Ethernet control connections on the server node connected to the two
VLAN switches.
During normal operation, one of the FSCs acts as the Primary Controller, while the other
acts as the Hot-Standby Secondary Controller. The Primary Controller controls the content
mirroring process of the Hot-Standby Secondary Controller; however, all MediaStream 8000
server nodes communicate directly with both the Primary and Secondary Controllers even
during normal operation and treat both FSCs equally. All File System requests issue twice,
one request per FSC, allowing for a transparent fail-over if one of the Controllers does not
respond.
Multiple Watch dog software modules distributed in the FSCs and the server nodes
constantly monitor the File System components and Ethernet connectivity. These software
modules ultimately make the decision if and when to switch the Secondary Controller to
become the Primary Controller. At that point the original Primary Controller is off-line and
can be serviced. Once the old Primary Controller comes back on line, it will automatically
become the Secondary Controller and will slave itself to the Primary Controller for content
mirroring and other housekeeping tasks.
Video Data Path Redundancy
The system is able to sustain a failure in one of the Fibre Channel data paths without
performance degradation, video loss, or jitter. The redundant data paths consist of the
following components:
•Dual Fibre Channel ports on the Fibre Channel card of the server node. These ports are
independent of each other in hardware and software.
•Dual RAID controllers per array. Both controllers are independent of each other in
hardware and software. Both FSCs have access to all of the storage at full bandwidth.
•Required Fibre Channel switches are always installed in redundant pairs.
•During normal operation, only one data path is used to read/write the data from/to the
storage system. If a failure in the data path occurs, the server node software detects this
failure in real-time and switches transparently to the other redundant data path. Since all
components are designed to deliver data at or above full bandwidth, there is no
performance degradation. The real-time fail-over design prevents video outages at the
decoder, as well as data overflow scenarios on the encoder system.

Adding Video Server Nodes and Channels
In most cases, adding additional video server nodes and channels to a system means that the
bandwidth requirement increases. Operators need to properly calculate if sufficient
bandwidth exists to support the increased channel count. This calculation can vary
significantly because it depends on how the system is used and operated in a given facility.
See for Appendix A for bandwidth calculation tables.
Adding additional channels to a server node is a straightforward process. Only the server
node that receives the channel upgrade needs to be shut down for the hardware and
configuration upgrade. Everything else will continue to operate normally.

Chapter 1 Introduction
Adding a server node involves hot-plugging the unit into the Ethernet VLAN topology to
provide file system connectivity and to connect the dual Fibre Channel interface into the
Palladium Store 1000 storage system. The Ethernet and Fibre Channel topology is factory
pre-configured to accommodate run-time configuration changes.
Adding Arrays to the System
Once the additional storage has been physically added, the operator needs to run File System
utilities to add the additional storage to the File System. For more information contact Avid
MediaStream Support.
The MSi Host PC
The system is administered via a host PC. The PC runs an application called MediaStream
Interface (MSi) that allows support personnel to playout, record, and run diagnostics on the
system components. Communication between the Host PC and the system components is via
redundant Ethernet connections to the dual VLAN switches. Depending on the
configuration, a storage cluster may have either one or two MSi PCs. Where there are two
MSi PCs, both have full access to all server nodes and both FSCs. Serial communication to
server nodes is provided by a Lantronix Ethernet-to-serial interface that integrated into each
server node chassis. This connection allows full access to the boot-up sequence of each
server node.

The MediaStream Interface (MSi) is a Graphical User Interface (GUI) application used for
administering the MediaStream Server. The MSi provides support personnel a means of
playing, recording, rebooting, installing new software, and performing other maintenance
activities on the server node. While the MSi is capable of performing many activities
associated with playing and recording media clips, it is meant to be used as a support and
diagnostic tool.

The data is updated automatically at regular intervals (about two minutes). A trouble
condition, reported in any of the server node’s key operating modules (disk drives, array,
power supply, or cooling fans), updates the System Status display and changes the button
alert color to red. Click the System Status button to see a graphic representation of the server

System Components
Although a MSS Networked Storage System may vary in scale and size, all systems share
certain components. This chapter examines the components that comprise a MSS Networked
Storage System:
•MediaStream 8000 server nodes
•File System Controllers
•Palladium Store 1000 Storage systems
•VLAN switches
•Fibre Channel switches
•MSi PC
•ConnectPlus 1000 NS Gateway PC
MSS 8000 Server Nodes
The MSS 8000 server node dseign uses VME 64-bit bus architecture (bus) and provides
high-speed communication between boards with a throughput of 400 Mbps. Direct
processing power is distributed among the cards plugged into the back plane.
The server interfaces with the station’s automation system using the RS-422 port with Video
Disk Control Protocol (VDCP) as defined in the Avid MediaStream VDCP documentation
and Ethernet LAN controls. Video content is sent in specified formats to the station’s routing
system.

In the rear panel, VME slot 1 (bottom rear slot) contains the System Controller (CPU)/Fibre
Channel board that provides system control and data transfer to the Palladium Store 1000.
Slots 2 through 10 (numbering from bottom to top) contain decoder and encoder boards. Up
to 16 input/output channels can be supported using a combination of single- and
dual-channel boards. The left side of the unit contains LAN connections and power
switches.
System Controller
The System Controller board regulates backplane traffic. It performs only a fraction of the
actual computing on the Server; other boards perform activities such as MPEG
compression/decompression. The System Controller Board regulates traffic by maintaining
the bit rates of real-time processes (play and record) at the expense of non-real-time
processes, such as administrative tasks. No encoder or decoder traffic actually passes
through the System Controller Board. Video Input/Output traffic passes directly across the
VME Bus to its destination.

Encoders
System encoders are responsible for coding video for storage on disk. Base band ITU 601
video enters the System via a Serial Digital Interface (SDI) port on the encoder board. A
601 signal has a bandwidth of 270 Mbps, far too high for storage on a storage array. The
encoder applies MPEG video compression to the signal, which reduces the signal to between
6 Mbps and 50 Mbps.
38
Boot disk
tray
Page 39
System Controller
After the signal is compressed it is passed through the encoder to the VME back plane and
through Fibre Channel Adapter (FCA) to the external storage array. Encoders do not have
circuitry for playing out video signals. Signals must first be recorded to disk. Playback and
preview is accomplished by playing disk-based segments through a decoder card.
Encoder cards cannot accept analog signals. These signals must be converted to ITU 601 via
an analog to digital converter. The Revision 3 Encoder supports encoding for up to 8
channels of embedded audio.
AES-EBU audio is connected through an audio input module, which is bridged to the
encoder with a custom cable. Encoders are controlled by automation systems via RS-422,
which guarantees frame accuracy in recording.

Decoder boards are required to playback signals from the array to air. Decoders output
embedded AES/EBU audio with SDI, separate AES-EBU and analog audio (via adapter
panel) and Composite NTSC or PAL analog video. Software must be configured for
embedded audio on or off. Video connections are via BNC while audio connections are
ported via a special cable to a breakout panel. A loop-through Genlock port and an RS-422
control port are included as well.
The board designs employ new audio connections and new automation connections.
Connecting cables ship with each board. There are different cable connections for the four,
six, and eight channel audio versions of the boards.
The Audio cable part numbers are as follows:
•PN: 51010004 Cable audio 4 channel
•PN: 51010005 Cable audio 6 channel “Y” (Decoder)
•PN: 51013529 Cable audio 8 channel “Y” (Decoder)
The SD (Standard Definition) board comes in Dual and Single configuration. The Dual
Decoder board provides two channels of playout on a single card. Each channel has a
composite video output and an SDI SMPTE 259M output. The connections for Dual and
Single Decoder boards are the same, but the video, audio and control connections for the B
ports are not active and are not labeled on the Single boards. The board has support for four,

The MSS Networked Storage System design employs redundant Windows 2000 PCs to
operate as external File System Controllers (FSCs). Regardless of the size of a server cluster,
the system will always use only two FSCs. These controllers manage the content database
that is accessed by all server nodes for content playout. FSCs occupy one rack unit each.
The Power button enables you to safely shut down the Windows OS component of the unit
for servicing without requiring access to a Windows 2000 interface.

Depending on the size of the cluster, different Fibre Channel switches will be used. The
Fibre Channel switches provide the link between the server nodes and the Palladium Store
1000 storage arrays. Each switch provides an independent path to each server node and to
each array. Up to 16 server nodes and one-to-eight storage arrays are connected to the
switches. Should any path fail on one switch, communication will continue via the
redundant path on the second switch.

When configuring one or more Gateway PCs into a networked storage system, special
consideration must be given to bandwidth load of the entire system. Each configured
gateway must be considered a server node with adequate bandwidth allocated for its use.
Failure to consider gateway impact on system bandwidth can have serious system-wide
performance implications. See Appendix A for more information on bandwidth calculations.

VLAN Topology
This chapter introduces the VLAN topology used in the MSS Networked Storage System.
Topics covered include:
•Hosts table
•Ethernet topology diagrams
•IP addressing scheme
VLAN Topology
The Networked Storage System uses redundant VLAN Ethernet switches to provide fast and
safe fail-over in the event of a break in network connectivity. Each switch provides isolated
connections between the server nodes and the two FSCs. The VLAN topology design
prevents network loop conditions that could lead to unacceptably long network time-out
scenarios during a LAN failure.
To ensure system redundancy, installation must conform explicitly to system design
parameters. Each switch must have the current firmware and the correct switchconfiguration files installed. With VLAN, a different network is assigned for each server
node providing isolated connection paths between the server nodes and the FSCs.
Page 52
Chapter 3 VLAN Topology
Hosts File
The hosts file provides name resolution for all devices within the cluster. The complete hosts
file on the FSCs and MSi PC is quite large and contains all names and addresses for all 16
possible clusters. Each server node contains a hosts file for a given cluster. An abbreviated
version of this file (with headings separating devices) follows. Sequential addresses have
been skipped, and any entry ending with xx… shows a continued sequence to the next entry.
Aliases
Some device hostnames have been provided with aliases to simplify the connection of
devices via Telnet. Connections can be established by using the hostname, LAN address, or
any provided alias.

VLAN Topology Diagram
The following diagram shows a logical Ethernet connections for the 24-port switch. Your
installed system ships with color-coded labels and cables to make both wiring and tracing
connections easier. This diagram will help you isolate network paths when servicing or
troubleshooting the system.
All tagged connections are VLAN logical connections while untagged connections are fixed
LAN addresses. For tagged VLAN connections, the sequence of addresses has been
abbreviated to simplify the diagram. In addition, only the last two octet groups of the address
are provided. The complete address includes the 10.xx prefix that designates the cluster.

Networked Storage System I/P Addressing
Scheme
IP Address Scheme Example
Network
Cluster
ID
The addressing scheme takes a 32-bit TCP/IP address and breaks it into logical units that can
be used to identify cluster, network IDs, and device IDs. The four-octet network address is
logically allocated to distinguish between clusters, VLAN networks, and device IDs. All
clusters are addressed as follows:
The first octet is always 10. The second octet designates cluster ID. Cluster 1 (the most
common) is 10.64.xxx.xxx. Addresses 64 to 79 are allocated for the first 16 clusters, with
clusters 17 through 32 using addresses 81 to 96. Clusters 33 to 48 use 64 through 79, but the
third octet (the network ID, described below) for VLANs in these clusters starts with 65
rather than 1.

The third octet grouping acts as a network ID, dividing a cluster into separate VLAN
networks, providing isolated communication paths for each server node. Sixteen separate
networks are allocated for server node communication with additional network paths
available for gateway, MSi PC, switch, and router traffic.
The fourth and final octet grouping acts as a device ID specifying the device type and/or
number in a storage cluster. The hosts file contains all addresses in all clusters with name
resolution for each device in a cluster.
The FSCs, MSi PCs, gateways, and routers employ VLAN Ethernet cards in addition to
standard Ethernet NICs to allow communication with devices across multiple networks
within a cluster.
Subnet Mask
The network uses the Class C subnet mask of 255.255.255.0, providing up to 256 individual
addresses per designated network ID.
Hosts Table and Addressing
Given the above parameters, the following devices are named and addressed in the hosts file
on systems components and integrated into the VLAN Switch:
•MSS 8000 server nodes and console ports

e.g., 10.64.1.4 for Network 1 Console Port 1 of Cluster 1
The device ID is always 4 for console ports.
There are two FSCs in each MSS Networked Storage System cluster. Each FSC has three
Network Interface Cards (NICs). The first is a VLAN connection to its primary switch. The
VLAN card is logically addressed (tagged) for communication with all configured networks
on the VLAN switch. This connection allows direct communication between the FSC and
each of the server nodes as well as the second FSC, MSi PCs, gateways and Fibre Channel
switches. The second is a direct connection to the redundant VLAN Switch. The third is a
direct crossover connection to the second FSC.
The convention for naming and addressing the three NICs is as follows:
58
Hostname
Hostname = fsc<xx><yy>-<z> where xx equals cluster number, yy equals FSC ID
(FSC A is “01” while FSC B is FSC “02”) and z is Network ID.
e.g., fsc0101-3 is FSC A of Cluster 1 on Network ID 3
Page 59
Networked Storage System I/P Addressing Scheme
LAN 1 Connection
LAN address = 10.<xx>.<22>.<z> where xx equals cluster ID and z is either “1” for
FSC A or “2” for FSC B.
e.g., 10.64.22.1 for FSC A on Cluster 1
n

MSi PCs
This is the crossover connection between the two FSCs.
LAN 2 Connection
LAN address = 10.<xx>.<21>.<z> where xx equals cluster ID, and z is either “1” for
FSC A or “2” for FSC B.
e.g., 10.64.21.2 for FSC B on Cluster 1
LAN 3 Connection
LAN address = 10.<xx>.<yy>.<z> where xx equals cluster ID, yy equals Network ID
and z is either “1” for FSC A or “2” for FSC B.
e.g., 10.64.3.1 is FSC A of Cluster 1 on Network ID 3
The VLAN card is configured for 17 logical addresses (from Network ID 1 to 17). It in effect
creates a “Virtual” Network Interface Card for each address. The hosts file for the VLAN
port on the FSC will include a hostname and LAN address for each of these.
A MSS Networked Storage System cluster will always have at least one MSi PC configured
but may have a second unit installed for redundant monitoring of the system. Each MSi PC
has one tagged VLAN NIC and one conventional Ethernet card installed. The VLAN
connection is for direct connection to the PCs primary VLAN switch while the Ethernet port
is for redundant connection to the secondary VLAN switch. The convention for naming and
addressing the two NICs is as follows:
n
Tagged VLAN Connection
Hostname = msi<xx><yy>-<z> where xx equals cluster number, yy equals MSi ID

LAN address = 10.<xx>.<yy>.<z> where xx equals cluster ID and yy equals network
ID; and z is either “5” for MSi 1 or “6” for MSi 2.
e.g., 10.64.3.5 for Primary MSi on Network ID 3
The VLAN card is configured for 17 logical addresses (from Network ID 1 to 16 plus
Network ID 21).

In all cases the device address is always 5 for MSi 1 or 6 for MSi 2.
A MSS Networked Storage System cluster may have optional gateways installed. The
gateways allow for content sharing between clusters and/or legacy MediaStream Servers. Up
to eight gateways may be configured into a system although a system is usually configured
for one or two. Each gateway has a VLAN NIC with three tagged addresses as well as an
untagged Ethernet port. The untagged port is available for connection to external networks,
not to the system’s switches. Since the gateways are not mission-critical on-air components,
redundant connections are not needed, and each gateway is connected to only one of the
VLAN switches:
Tagged VLAN Connection
Hostname = gwy<xx><yy> where xx equals cluster number and yy equals gateway
number; gateways are numbered from 1 to 8.
e.g., GWY0101 = Gateway 1 in Cluster 1
LAN address = 10.<xx>.<yy>.<zz> where xx equals cluster ID, yy equals Network ID,
and zz equals device ID. Gateways are ID’d from 11 to 18.
e.g., 10.64.16.11 for Gateway 1 ID 11 on network ID 16
Each gateway has tagged VLAN addresses for network IDs 1 through 16 and 21. Gateway
device IDs will always be between 11 and 18 (11 for Gateway 1 and 18 for Gateway 8).
60
Gigabit Ethernet Connection
Hostname = gwy<xx><yy> where xx equals cluster number, yy equals gateway
number; gateways are numbered from 1 to 8.
e.g, GWY0101 = Gateway 1 in Cluster 1
LAN address = 10.<xx>.<yy>.<zz> where xx equals cluster ID, yy equals network ID,
and zz equals device ID
e.g., 10.64.128.11 for Gateway 1 in Cluster 1 on Network ID 128
Page 61
Fibre Channel Switches
A LAN connection is provided for each Fibre Channel switch to the VLAN switches to
provide access by the MSi PC for maintenance purposes. Each FC Switch is connected to
one of the VLAN switches. It is important to note that redundant connections are not
available, and monitoring will only be possible from MSi 1. These connections have been
provided as a convenience when servicing the switch.
Hostname = fc<xx><yy> where xx equals cluster number, yy equals FC switch
number. Switches are designated A or B.
e.g., FC0101 = FC Switch A in Cluster 1
LAN address = 10.<xx>.<yy>.<zz> where xx equals cluster ID yy equals network ID
and zz equals Device ID. Device ID is 36 for FC Switch A and 37 for FC Switch B.
e.g., 10.64.21.36 for FC Switch A in Cluster 1 on Network ID 6. and 10.65.17.37 for FC
Switch B on Cluster 1 Network ID 17
Networked Storage System I/P Addressing Scheme
n
Routers
FC Switch A can communicate with MSi PC 1 on Network ID 21 while FC Switch B is set to
Network ID 17 to allow communication with MSi PC 1 through its direct connection on
Network ID 17 with VLAN Switch 2.
A MSS Network Storage System cluster may be configured with optional routers to allow
communication to occur between the cluster devices and an internal LAN in the facility.
Each router is configured with a VLAN NIC to allow communication between configured
Network IDs and external devices. With redundant routers connected to each switch,
redundant communication paths are available to external networks The VLAN addresses are
configured as follows:
LAN address = 10.<xx>.<yy>.<z> where xx equals cluster ID, yy equals network ID
and z equals router device ID. This is 32 for Router A and 33 for Router B.

Site Preparation Time Table (Continued)
Time
Frame Activity
6 weeks
prior to
installation
Create a site layout plan.
Schedule with appropriate trades persons to ensure that the site is in compliance
with structural, power, interface, and environmental specifications.
Obtain external cables as necessary. Avid MediaStream provides cables to
connect Avid MediaStream server components. (Check with your Avid
MediaStream Sales Representative if you plan to attach multiple arrays.) You
need to provide external connections to station automation, video, and audio
devices. See Appendix B.
Follow these guidelines when preparing your site for the installation
•Allow enough space at the site to accommodate additional servers and arrays should
your requirements increase.
•Locate cables away from traffic paths to prevent accidents and equipment failures.
•Allow space for a monitor to connect to the analog output of each decoder.
•Consider space for your MSi PC (racked or adjacent).
•Consider space for other equipment, such as the automation station.
•For proper ventilation of the MSS 8000 component racks, and to ensure enough room to
perform periodic maintenance and servicing, install the MSS 8000 components a
minimum of 40 inches (1 m) (front and back) from walls or other items that might
obstruct airflow or the removal of modules.
Avid MediaStream Support recommends that the equipment racks be anchored at the ceiling
or floor or bolted to the wall. Ensure that the racks will be stable when all equipment is
loaded into the racks. The center of gravity in a fully loaded rack must be low enough to
keep the rack from being top heavy.
This section addresses floor load limits, vibration, and heat dissipation.
Floor Load Limit
The room that will house the MSS 8000 must be able to support the total weight of the
various components, as well as the localized weight at each level of your rack or cabinet.
To estimate floor strength requirements, consider the following items:
1. Total weight of the MSS 8000 components and any associated equipment.
2. Total weight of furniture such as desks, chairs, tables, racks, etc.
64
Page 65
3. Total approximate weight of the operating personnel.
4. Weight of the moving equipment (such as forklifts and transport dollies).
Ensure that all floors, stairs, and elevators to be used when the server is moved to its
destination can support the weight of the server and moving equipment.
Refer any questions regarding the adequacy of floor construction to a qualified structural
engineer for evaluation.
Vibration
Vibration, when severe, can cause a slow degradation of mechanical parts and connections
and data errors in disk drives. If you suspect that vibration might be a problem, contact Avid
MediaStream Technical Support for advice and recommendations.
Heat Dissipation
Consider the heat dissipation by the MSS 8000 components as well as other equipment at
the site, individuals working at the site, and lighting to determine whether the existing air
conditioning system is adequate, or if an upgrade is necessary.
When estimating heat dissipation, consider the addition of Networked Storage components,
should your requirements increase.
Environmental Considerations
n
The cooling air for the server flows in the front and out the left side of the unit. Make sure
that there is enough space between the left side of the server and other equipment in
neighboring racks so warm air can escape.
Environmental Considerations
This section covers ideal operating temperature, electromagnetic interference, and
electrostatic discharge.
Temperature and Humidity
To ensure that airflow is not impeded, and to ensure adequate space to perform periodic
maintenance and servicing, do not place racks closer than one meter to walls or obstructions
in the front and back.
For reliable operation, maintain room temperature between 20 and 25 degrees Celsius (68
and 77 degrees Fahrenheit), and relative humidity between 30 and 50
65
Page 66
Chapter 4 Preparation and Installation
Electromagnetic Interference
The MSS Networked Storage System is designed to reduce susceptibility to radiated and
conducted interference. The MSS Networked Storage System conforms to the
electromagnetic susceptibility (EMC) standards. Excessive electromagnetic interference can
cause a variety of problems. Avid MediaStream Support can advise you about the most
common causes of electromagnetic interference.
Electrostatic Discharge
Static electricity at the MSS Networked Storage System location should be within the
normal range (lower than 15 KVs). Carpeting or low humidity will facilitate the generation
of static electricity, especially in dry and cold climates.
To reduce static electricity, install grounded mats in front of the MSS Networked Storage
System. Avid MediaStream Support recommends using a heat evaporating humidifier (and
strongly recommends against using a cold water atomizer humidifier).
Anti-static spray is not recommended because it can enter the intake filters and coat the
circuitry. If you must use a spray, apply it while the MSS Networked Storage System
components are turned off.

Use the following checklist to schedule activities and to monitor the progress of the site
preparation process.

Receiving Server Components
The server, MSi PC and its monitor, File System Controllers, switches, the array(s) and
other components are packaged in separate containers. If your shipment includes the
optional Rack Mounting Kit for the MSi PC, you will receive additional boxes that contain
the rack-mounting accessories.
When the shipment arrives, check each container against the carrier’s shipping documents.
Inspect the exterior of each container immediately for mishandling or damage during transit.
If any of the containers are damaged, request the carrier’s agent be present when the
container is opened.

Do not throw anything away until you have found and unpacked all of the components.
To protect the components, leave them in their packaging until you are ready to install them.
Keep the shipping materials. If you have to repackage any of the components, you will need
the original shipping materials.
The MSS Networked Storage System components are fragile. Some components can be
damaged even when carefully handled. Move components in their original packaging.
The components are packed in containers that can weigh more than 120 pounds (55
kg). Exercise care when moving them to avoid injury.
The server ships in a wooden crate. Ensure that doorways and pathways are wide enough to
allow passage. The following table shows the dimensions of the boxes and crates.

Use an elevator to move containers. Stairs may result in excess vibration. Leave components
in the packaging until you are ready to install them.
Never touch any exposed electrical connectors on the components as they can be
damaged by electrostatic discharge (ESD). Never drop or sharply bump the array(s).
This can cause immediate or delayed failure of the disk drives, permanent data loss, or
intermittent operation.
A server ships in one crate and several boxes. Carefully check all compartments of each box.
Page 69
To unpack the crate:
1. Remove the wire clips that surround the top of the crate and remove the lid.
2. Remove the front panel, rack ears, cords, and accessories from the pockets around the
inside of the crate. Some small items may be in packaging material.
3. On the outside of the crate, unfasten the latches that secure the sides of the crate to its
bottom. To unfasten the latches, flip the lever of the latch up, and then turn the lever
counter-clockwise.
4. Lift the crate up and over the main server chassis, placing the crate out of the way.
5. Remove all packing foam surrounding the server.
Inspecting the Contents of the Shipment
As you unpack the shipment, account for and inspect all the components:
•Check each container against the packing list to ensure all shipping containers were
received.
•Check all packing materials and containers for the missing components. Small
components, such as adapters and short cables, can remain undetected in the packing
materials.
•Check the packing foam for damage that indicates rough handling during transit.
Receiving Server Components
•Look for broken controls and connectors, dented corners, scratches, bent panels, and
loose components.
•Check the exterior of the components for the following signs of shipping damage:
-Look at the top and sides for dents, warping, or scratches.
-Check the connector panels for signs of damage (bent or broken connectors,
scratches, and so forth).
If you have any problems with the shipment, refer to the claims procedure guidelines.
Claims Procedure Guidelines
If you found any damage, follow these claims procedures.
n
Some damage may be repaired by replacing the part. In the case of extensive damage, you
need to return all of the components to Avid MediaStream Support. Contact your Avid
MediaStream representative immediately.
Notify your Avid MediaStream representative if the shipment is incomplete or if any
shipment contents are damaged. If damage occurred in transit, also notify the carrier.

Server Repacking Guidelines
Technical Assistance
Avid will arrange for repair or replacement without waiting for settlement of claims against
the carrier. If damage occurred during shipping, retain the packing container and packaging
materials for inspection.
To repackage any of the server components for shipment, reverse the appropriate
unpacking procedures.
Use the original packing material to repackage the components for shipment. If the packing
material is not available, contact your local Avid MediaStream Support Sales and Support
Office in the U.S., or contact your Avid MediaStream Support authorized dealer outside the
U.S. regarding shipment.
If your server is still under warranty:
•Before you call Avid MediaStream Support, record the model and serial numbers of
your server. You need to remove the front panel to locate these numbers.
•If you opt to have a replacement part shipped to you, retain the packaging materials for
the return shipment of the failed assembly, and follow the instructions on the Return
Authorization Form that will be included with the part.
•Customers outside the USA should contact their local dealer or Avid MediaStream
Systems representative for assistance in diagnosing a problem and identifying a possible
failed assembly.
After the warranty expires, you can purchase a Avid MediaStream Support service contract.
Please contact your Avid MediaStream Support Sales Representative for more information.

Installing the MSS Networked Storage System
A rack unit (RU) is the measurement rack manufacturers use to measure the height of
equipment mounted in the rack. A rack unit is 4.45 centimeters (1.75 inches). Some rack
manufacturers provide an additional hole or other symbol to mark the rack unit, as shown in
the following figure.
w
70
Because of the weight of the some of the units, installing the MediaStream server and
Palladium Store 1000 requires at least two people. A third person may be needed to
stabilize and guide the chassis while two others lift and slide the module onto the rack
rails

For example, a basic MSS Networked Storage System requires a six-foot or two-meter rack.
Additional server nodes or storage arrays will require additional racks.
n
Before installing any components, be sure your rack is stable. Avid MediaStream Support
recommends anchoring your rack at the ceiling and the floor. All persons building racks or
installing components into racks should have the physical strength, training, and equipment
to manipulate heavy objects without causing personal injury.
Each MSS Networked Storage component is labeled. There are always two File System
Controllers (FSC A and FSC B), two VLAN Switches (VLAN A and VLAN B), two Fibre
Channel Switches (FC A and FC B), and at least one server node (MSS 1) and storage array
(Array 1). Additional server nodes and storage arrays have sequential numbers.

EIA Racks
Make sure that your rack hardware, including protruding screw heads, leaves at least
44.2 cm (17.4 inches) of clearance.
Rack Dimensions
Placing Supports
Avid MediaStream ships two supports and two mounting ears that form a shelf in the
equipment rack for the server. The ears are brackets that attach to the front of a server and
allow the chassis to be secured to the equipment rack.
The supports will mount anywhere because the holes are spaced one rack unit apart. The
center hole (the hole between wide gaps) in a rack unit is generally used to mount the
module supports. See the following figure.
74
Page 75

Rack
The hole at the center of a rack unit is
generally used for mounting
supports.
Support
Most supports and components
align with the bottom of a rack unit.
The support hole pattern is designed to fit vertical rack rails, and not interfere with chassis
placement.
The MSS 8000 components are secured to the equipment rack by attaching the mounting
ears to the vertical rails of the rack. If you install the module supports correctly, the ear holes
on the chassis mounting will have clear access to the rack-mounting holes. See the following
figure.

Even-height components add another level of complexity. The following figure shows an
example of two odd-height modules (IR and 3R units), and an even-height module (2R
units). The odd-height support’s rack ear holes should align with holes that are an equal
distance from a rack unit center hole. Even-height component mounting holes may align
with holes that are an equal distance from the narrow gap between rack units. If you mount
the module supports correctly, you should avoid a mounting hole versus rack hole conflict.

Adjusting Supports
Measure the required space from the top of the rack. Install supports from the bottom of the
rack.
The recommended rack depth is from 66.6 to 91.6 cm (26 to 37.4 in.). After reviewing the
previous figures for the support vertical placement, adjust the support to fit your rack depth.
Use M5 panhead screws to adjust supports. Install the supports to the inside surface of the
rack rails as shown in the following figure.

The support mounting hole has an attached threaded per nut to receive the M5 screw. The
support depth is adjustable to fit racks as shown above. To adjust the supports, loosen the
four M5 screws, adjust the depth, and then tighten the screws.
Racking the Storage Array
The storage array comes with its own mounting hardware and instructions.

Avid MediaStream recommends that you have two persons lift the storage array and that you
install it as low on the rack as possible.
Racking the Server
w
The server weighs as much as 25 kg (55 pounds). Installing the server is a two-person
job. Occasionally, a third person may be needed to stabilize and guide the chassis while
two others lift and slide it into position.
To install the server into the rack:
1. Ensure that you are using either an anti-static wrist strap or mat.
2. Remove the server from the shipping crate.
M5 screw
3. Lift the server and slide it onto the rack rails. Do not insert the chassis all the way into
the rack. Instead, insert the chassis about 3/4 of the way onto the rails so that you can
access the front of the unit.
4. Detach the shipping cover from the front of the server by removing the screws that
secure the cover to the chassis.
77

Chapter 4 Preparation and Installation
n
Be careful not to bump or damage any of the components on the LED panel at the top front
of the chassis. The front panel, which you install last, protects the components. Save the
screws that you removed. You will use these screws to attach the ears onto the server. (The
ears will allow the chassis to be secured to the vertical rail of the equipment rack.)
5. Attach the ears to the sides of the server chassis using the screws that you removed from
the shipping cover.
The ears are packed in the shipping crate with the server.
6. Slide the server chassis all the way into the equipment rack.

components facing backwards in the rack. For easier connections and better cooling, install
a File System Controller on top, a VLAN Switch below it, leave a 1 RU space, and then
install the other FSC with the remaining VLAN Switch below it.
The 1 RU gateway comes with its own mounting hardware and instructions. Your system
will have one or more Connect Plus 1000 Gateways. Depending on how many are installed
in your system, they may fit in the rack near the FSCs, MSi PC and VLAN switches.

Correct connections are essential to proper system operation and to maintain full
redundancy. It is possible to make the wrong connections and obtain some degree of
functionality but lose redundancy.
Connecting Video
Avid MediaStream products ship with all of the cables for connecting the MSS 8000 server
components. You provide external connections to station automation, video, and audio
devices. To prepare inputs and outputs for your MediaStream server, you need to know how
many encoder and decoder assemblies you will receive with your server. You need to
prepare one set of input cables for each encoder assembly and one set of output cables for
each decoder assembly. See Appendix B for connector and cable information.
The following figure shows the video input and output connections on the encoders and
decoders, respectively.

Video Input
Video input to the encoder must be in serial digital form, as specified by the IRU-R BT.6012 standard. Analog video must be converted into serial digital form to be input to the
encoder. This can be accomplished with a third-party analog-to-digital converter module.

Video Output
Video output from the decoder can be in both serial digital and analog format.
Serial Digital Output
Decoders provide a standard ITU-R BT.601.2 serial digital signal, as well as a composite
analog output that is suitable for station monitoring. Audio is embedded with the video track
and is also available in AES/EBU and analog via optional XLR or BNC audio output
modules. Serial digital may be converted to broadcast-compliant analog composite or
component video via an external serial digital-to-analog converter.
The following figure shows serial output from four decoders on a server to a digital-toanalog converter.

Connecting Genlock (Black Burst)
The Genlock connector on the decoder assemblies allows video output to be synchronized
with a station reference signal, also known as black burst. Once the station reference signal
is made available to the first decoder in the server, additional decoders are connected via
loop-through ports.
The last loop-through output should be terminated with a 75-ohm load. With the dual
decoder board, termination is internal and automatic. Therefore, if the last board in the loop
is a dual decoder board, or your server has only dual decoder boards, you do not need the 75ohm terminator.
The following figure shows the connections for station reference and loop-through outputs:

The server node accepts audio input that complies with AES/EBU (digital) standards. The
server‘s encoders receive AES/EBU audio signals through an HD-26 pin connector. Analog
audio input may be made compatible with the AES/EBU standard with a third party analogto-digital solution.
Audio connections vary from station to station. Your station may have digital audio, analog
audio, or both. You may use either 75-ohm BNC or XLR, or both.
