Prepare for core configuration stages
Calculating encoder bandwidth
One feature of the K2 iSCSI network is its ability to load balance each iSCSI client’s
connection to the K2 storage system. In order to do this, calculate the amount of
bandwidth each client machine will use, using this formula:
(Video Bit Rate in Mbps x Number of Streams) / 8 (to convert to MB)
1. Determine the highest bit rate you use on the Advanced encoder or SmartBin
encoder.
The bit rates for the DV formats are: DV25 = 28.8 Mbps; DV50 = 57.6 Mbps; and
DV100 = 115.2 Mbps for the NTSC and PAL video formats.
MPEG bit rates are variable; enter the bit rate set in Aurora Edit.
2. Multiply the highest bit rate by the number of streams that are licensed on this
machine. Only one stream should be configured on a Advanced encoder or
SmartBin encoder (Aurora FTP and SmartBin Service if there is one), so for
encoders you always multiply the highest bit rate by 1, which of course does not
change the value.
3. Divide that number by 8 to convert Mbps to MB.
4. Round the MB number to the nearest integer.
5. Enter this number in the iSCSI Client Bandwidth Input screen in the K2
Configuration application wizard.
6. At the conclusion of the configuration process, the K2 Configuration application
restarts the encoder.
Prepare NAS - Windows Fastora
For the Linux version, refer to “Prepare NAS - Linux Fastora” on page 153 .
NOTE: Procure IP addresses from the local network administrator prior to
configuring the NAS unit.
When you configure the Windows Fastora NAS for the Aurora Browse networks, you
can make network settings in the following ways:
• Use Windows Remote Desktop Connection, as explained in step 4 of the
following procedure, and then use standard Windows procedures to make all
settings. If you do this, read the subsequent steps in the procedure to identify the
required settings.
• Use the Fastora configuration pages (Web based), as documented in the
following procedure, and make settings as instructed.
NOTE: If you plan to change the name of the NAS unit and you intend to use the
underscore character, such as in root_nb_nas_n, you must do so using standard
Windows procedures via the remote desktop. The Fastora configuration page does
not allow the underscore character.
To configure the Windows Fastora NAS for the Aurora Browse networks, do the
following:
1. From any Production network machine, enable the network to recognize the NAS
