•QOS Token Hold Time: This parameter is only applicable when using the StorNext FS Quality of Service (QOS) feature for real-time I/O. This parameter determines the number of seconds that a client stripe group will hold on to a non-realtime I/O token during periods of inactivity.

•Debug: Check this box to place debug logs in the System Event log.

•Hard Reconnect: Check this box to endlessly attempt reconnects to the FSS.

•Hard Mount: Check this box to endlessly attempt to mount the file system.

•Read Only: Check this box to mount the file system in read-only mode.

•Paged DirCache: This option controls how the directory cache buffer is allocated. The default is to allocate the buffer from the Windows "non-paged" pool, which is a limited memory resource. For backward compatibility reasons the default for this option is unchecked, which causes the directory cache buffer to be allocated from the non-paged pool. Checking this box allocates the buffer from the paged pool. To reduce memory contention in the non-paged pool, this box should be checked

•I/O Timeout (60 sec): This option controls whether SNFS times out an I/O after 60 seconds. When this option is checked (the default), SNFS will attempt to cancel a request made to the disk driver if the I/O does not complete before the timeout expires. In this case, STATUS_TIMEOUT is returned to the application. When this option is unchecked, SNFS waits indefinitely for an I/O to complete.

•Disable Buffer Cache: Check this box to disable the system from buffering any files.

•Allow Diskless Mount: Check this box to allow the file system to be mounted and accessed without all disks being accessible in the stripe group.

•Fast Failover Detection: Check this box to enable a more aggressive detection of a file system failure.

•Delay Atime Updates: Check this box to have the file system delay the access time when reading a file to when the file is closed.

•Readonly Directories: Check this box to have all directories set to read-only mode.

•Protect Preallocation: This option disables the preallocation parts of the extapi (used by cvmkfile and cvcp) for users other than root/administrator. Enabling this option prevents unauthorized users from preallocating regions of the file system for a file and then searching the data. When this option is selected, only root/administrator can preallocate.

•File Name Case Insensitive Check this box to activate the New File Name Case area.

•New File Name Case area:

•Preserve Case: Select this button to keep text as it is entered.

•Convert to Lower: Select this button to convert all text to lower-case.

•Convert to Upper: Select this button to convert all text to upper-case.
