System Components

Cerify accesses digital media from local storage, such as a local hard drive or DVD, as well as network storage, such as a Windows ﬁle server or FTP server.

A Cerify system can be set up in two basic ways:

The ﬁrst consists of a single self-contained unit which runs all the management and testing processes

of the system.

The second consists of a networked cluster of three or more units, which enables simultaneous

processing of a greater number of ﬁles. The networked cluster contains a single Supervisor and one

or more Media Test Units.

Cerify Automated Video Content Veriﬁcation System User Manual 11

Getting Started System Installation

System Installation

This section provides details of hardware, software and user prerequisites for the system and instructions on performing the software installation.

Prerequisites

Hardware Prerequisites

Cerify is designed to be run on a variety of PC hardware. Consequently, the choice of hardware is determined by performance and throughput requirements for your installation.

This section recommends hardware conﬁguration for some situations in which Cerify is typically used.

Cerify can be installed as either of the following two conﬁgurations on a given computer:

Single channel. A single channel installation is one that is licensed to test a single media ﬁle at a time. Such installations are normally performed on a PC or a laptop computer and are suitable for situations where a low throughput is sufﬁcient and performance is not critical.

Multichannel. A typical multichannel installation of Cerify tests 4-8 media ﬁlesatatimeona single unit. Due to the high throughput and performance requirements that are expected from such installations, it is recommended that server class hardware and operating systems be used in such cases.

In addition to the throughput required, the hardware requirements also depend heavily on the mode of operation that will be used. Cerify can operate in two modes:

Streaming mode

In this mode, media ﬁles are read directly from the media server hosting the ﬁle and are not copied to the local hard disk of the Cerify system. This is the default mode of operation and is also the preferred one.

Copying mode

Media ﬁles are copied to the local hard disk of the Cerify system before processing can begin. By default, Cerify will not copy ﬁles to the local hard disk, but it is possible to force Cerify to operate in this mode.

The mode of operation that applies to your Cerify installation depends on the ﬁle formats you would like to test and other work ﬂow and connectivity related constraints that might apply to your situation. See the

Modes of Operation

The functional differences between these two modes of operation impact primarily on the disk space availability and disk conﬁguration requireme of disk space and high levels of concurrent read/write performance from the hard drives in order for best overall performance while the streaming mode can derive comparable overall performance with a lesser amount of disk space and lower read/write efﬁciency. Consequently, when possible, the streaming mode should be used in preference to copying mode.

(see page 237) for a detailed discussion on the factors that inﬂuence this.

nts. Speciﬁcally, the copying mode requires a greater amount

12 Cerify Automated Video Content Veriﬁcation System User Manual

Getting Started System Installation

The general guidelines that should be followed when selecting hardware are:

Processor: 3 GHz

Cerify is capable of using as many processor cores as available for improved processing performance.

While the minimum required conﬁguration is 2 cores per channel, for optimum performance, it is

recommended to allocate between 4 and 6 processor cores per Cerify channel. It is also recommended

that for best performance, you choose as much on-chip memory cache as possible.

NOTE. Cerif Intel based server platform.

Memory:

It is recommended to use a minimum of 4 GB of RAM per channel and an additional 4 GB for the

operati

memorythereforeis:4x4GB(perchannel)+4GB=20GB.WhentheexpectedloadinCerifyis

likely to be largely composed of huge media ﬁles, more memory per channel may be necessary.

Hard disk drive: 100 GB x 3

For an e

Windows and Cerify installation (including database) to achieve fault tolerance in case of disk failure.

This logical drive should be at least 100 GB in size. For systems that are expected to support high

levels of throughput, it is recommended that you have 500 GB of space on this logical drive.

The amount of additional storage you need depends on the mode of operation that applies to your

installation, the average size of the ﬁles you will be processing and the number of channels you

will be running.

y is optimized for Intel processor architectures, and therefore it is recommended to use an

ng system and the Cerify database. For optimum performance for 4 channels, the recommended

nterprise installation, Tektronix recommends using a RAID on which to place the MS

Streaming mode

Due to the minimal hard disk utilization when operating in the streaming mode, it is sufﬁcient to provide a single dedicated hard disk of 100 GB in size as temporary storage for Cerify.

Copying mode

The minimum hard disk space provided must be greater than the average ﬁle size being processed multiplied by the number of channels. It is recommended that the temporary storage be RAID-ed for better performance.

For help choosing the optimal number of hard disks for your installation and the best RAID levels to

use, see Conﬁguring Your Cerify Installation for Best Performance

Network interface: 1 Gbit/s

You might use multiple network interfaces to improve available network bandwidth.

The installation of the Cerify takes several minutes; typically between 5 and 15 minutes depending on the speed of your PC. To install Cerify, perform the following steps:

1. Run the Cerify Installer.

2. Inser

t the Cerify dongle.

3. Optional: Install Apple QuickTime Player.

Before installing the Cerify, you should be aware of the following issues:

1. It is recommended that the Cerify application be installed on a machine where it can b e used as the

sole running application. Cerify makes intensive use of both CPU and memory and will considerably

degrade the performance of other running applications. Similarly, running other applications or

rvices simultaneously will degrade the performance of Cerify and increase the time taken to process

amediaﬁle.

erify relies on third-party software applications that are packaged and installed with it: JBoss and

2.C

MySQL. If these applications are already used on the PC, you should remove them before attempting

to install the Cerify.

3. The Cerify license server relies on Sentinel HASP (formerly Aladdin HASP SRM) drivers, which are

installed and conﬁgured along with it. It is recommended that other applications that rely on HASP

licenses not be used with Cerify on the same machine.

4. Cerify uses a number of network services that are local to the host PC. These services can sometimes

be blocked by personal ﬁrewall software , in which case an error message will be displayed when Cerify

starts. For example, on Cerify start up, a check is made to verify that communication with HASP can

be established. If the Cerify application is unable to communicate with HASP, an error message,

Unable to connect to HASP License Manager (port 1947). Please check if the HASP License

Manager service is running and is not blocked by a ﬁrewall is displayed and Cerify is stopped.

In such situations, conﬁgure the ﬁrewall to allow the service on the appropriate port, or alternatively

disable the ﬁrewall entirely.
