Calculating K2 Dyno PA machine bandwidth
One feature of the K2 network is its ability to load balance the K2 Dyno PA machine’s
iSCSI connection to the K2 storage system. In order to do this, calculate the amount
of bandwidth each 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 K2 Dyno PA machine. 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 K2 Dyno PA.
2. Multiply the highest bit rate by the number of streams that are licensed on this
machine. For systems such as K2 Dyno PA, only one stream is available for each
K2 Dyno PA machine.
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.

Prerequisites:
• The standalone or K2 Summit SAN system must have been configured as described
in the section on configuring your K2 Summit system.
• A K2 Summit system, referred to as a server in the K2 Dyno PA application, must
have been added to the Dyno PA client.
• The K2 Dyno PA machine must have the requirements described in the K2 Dyno
PA Prerequisites.
• The K2 Dyno PA machine must have the identical FsNameServers file as the K2
Summit system. This file must be in the C:\SNFS\Config folder on the Dyno PA
machine. For more information, see About configuring K2 Summit systems and K2
Dyno PA .
To enable the Browse feature on the K2 Dyno PA application to work with a K2
Summit system, the K2 Summit system needs to be configured for K2 Dyno PA and
the SNFS software needs to be configured on the Dyno PA machine. This section
describes configuring SNFS software for the DLC or iSCSI client on the Dyno PA
machine.
1. If you do not already have the K2 Dyno PA application open, start it now.
2. Right-click on the K2 Summit system in the Navigation pane, and select Edit Server .
The Add/Edit Server Device dialog box displays.
