About This Appendix
NOTE This appendix applies to the Stone filesystem only. The new HP z800 workstations running under Red Hat
Enterprise Linux 5 do not support Stone FS storage.
The tables in this appendix provide recommended inode ratios for single resolution workflows on XR-series
storage. If you are using a mixed resolution workflow with XR-series storage, use the inode value for the
lowest resolution. For example, if you use NTSC and HD resolutions in your workflows, use the inode ratio
value for NTSC.
About Inodes and Inode Ratios
An inode is a data structure that holds information about a single frame stored in a Stone partition. Each
frame in your clip library is identified by a single inode in the Stone partition.
When you set up your Stone filesystem, you must enter an inode ratio that is used to calculate the total
number of inodes available per Stone partition. For example, you might have one inode for every 2048 KB
of filesystem space. If you have an 8TB filesystem, this would provide you with 4 million inodes, and therefore,
the possibility of storing 4 million frames.
