Accessing the Omneon MediaGrid 4. Omneon MediaGrid File System Driver Parameters 5. Complete the settings as follows: • In the Application Performance section: • Set the appropriate ReadAhead values. See the latest Omneon MediaGrid Release Notes for Windows FSD for the currently supported range of readahead values. It is recommended that you map the Omneon MediaGrid file system drive once again to ensure the changes take effect. • For the MaxConnection field, Omneon recommends that you leave the default value of 8 unless you plan on using an application such as MXFServer. In this case, refer to the Omneon MediaGrid Release Notes for Windows FSD for recommended settings. • Select Disable CRC check on read if you wish to disable the CRC check to reduce CPU usage. • In the Application Feature section: • Select Disable case insensitivity if you would like to set the file system to be case sensitive. By default, the Windows file system is case insensitive (for example, File 1 and file 1 can be used). Checking this box is useful when the Omneon MediaGrid system has a large number of files. • Select Enable multiple NIC support to utilize computers with multiple 1 gigabit Ethernet ports, enabling all ports to access data on Omneon MediaGrid. By default, Multi-NIC support is disabled in the Windows FSD. IMPORTANT: If you modify the setting for Enable multiple NIC support, you must click Apply and then restart your computer in order for the changes to take effect. • Click Deny file deletion if used by other to prevent any user from deleting a file that is in use by another user. • The Application Profile section provides control over the priority of access requests issued to Omneon MediaGrid. Access requests can be set to normal or nonlinear (high priority). 150 Installation and Configuration Guide
