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.

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.

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

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.

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.

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.

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.
