    Large RAID array, large file count...

    I'm moving towards setting up a 2TB RAID.  I am hearing that there may be trouble with large file counts in the OMFI databases (and unknown if there is a problem with MXF databases).

    Does anyone have experience with this size, single raid?  I know I need the storage, and I'm not sure of a better way to do it.


    Thanks

    Well running a 6 tb raid5 setup in 2x2 tb and 1x1 tb partitions (1 tb for redundancy)... windows had problems with building partitions over 2 tb. No problems with the filecount, BUT i do capture all at max resolution so i think i run out of disk space before i run out of the number of files windows/avid is able to deal with. Also i use mxf, which is better equiped to deal with a lot of files. Beside that, i rename the MXF/OMFI folder to the project name if i continue to work on a different project.

    What do you mean by this?  Is this the virtual drive idea that I am reading about on the forums?  Can I rename the MXF folder and still access it?

    No, once you rename that folder it becomes invisible to Avid. Do a search on Virtual drives - I think they are a great way to manage media on large arrays.

     I change the names so it that project becomes invisible for avid, and i dont run into trouble with mediafiles of several different projects in one OMFI/MXF folder. The folder is of course still accessable in windows of course. I dont know about virtual drives... I do know about shared folders that can be mapped as a drive, so you can use the harddisks two or three avids connected by Gb lan as kind of a poor man's unity/lanshare

    Re: Large RAID array, large file count...

    Just to clarify, when using the MXF format/file structure, there is no problem - Avid automatically creates a new directory when the number of files exceeds 5,000 files or so.

    If you look inside the Avid MediaFiles / MXF directory, you'll see a folder called "1".  When the number of files exceeds 5,000, it will create directory "2", and so on.  All sub-folders within the "MXF" directory will appear online within Avid.
