| I'm unable to save FCP project files onto the SAN volume, getting an "Unknown File" error message. | Oct-18-12 |
| This has been a known issue with Final Cut Pro 5, 6, and 7. Currently, the best practice is to open and save project files locally such as on your Desktop (only the .fcp file. The media can obviously stay on the SAN). When you are done working with with the project you can safely copy the project file to the SAN with the Finder to store it and then when you want to use it again you copy it back down to your Desktop. The only issue obviously becomes versioning control. Unfortunately there is no real work around and is an issue with Final Cut Pro when it is writing the actual project file to a SAN volume. If you decide to continue to work directly off the project file on the SAN you WILL continue to get this error at random intervals and when it happens your only recourse is to do a SAVE AS and save it to a local disk. If you really need to store project files where multiple people can access it then you might want to look into Final Cut Server because when you check out a project in Final Cut Server it actually stores the checked out copy of the project file locally and then when you check it back in it copies the file back so the project file is never actually being written by Final Cut Pro to the SAN\u8212 Tech Tip coutesy of Christopher Colline, Senior Systems Engineer, Mac Professionals. |

| My MetaLAN performance from the VFibre is less than I expect. What can I do? | Dec-05-12 |
| Make sure your RAID is set with a 128k interleave with the ATTO RAID Config Utility. Anything larger will result in a gross mismatch of ethernet packet size and drive buffer size, adversely affecting storage access performance over Ethernet.
You can try increasing the buffer size on the 10G Ethernet card. The default is 500 read buffers and 500 write buffers. Try 2500 read buffers and 2500 write buffers.
If you are accessing large files, then turning on Jumbo Packets on both the VFibre and all the workstations may help increase performance. NOTE THAT JUMBO PACKETS NEED TO BE EITHER ON AND OFF ON ALL WORKSTATIONS AND THE VFIBRE, OR ELSE PERFORMANCE WILL GREATLY SUFFER FROM THE MISMATCH.
Try not to use any small ethernet hubs in your system. If you do, then turn off flow control on any port connected to a hub. Otherwise back pressure jamming signals may degrade overall performance for the segment connected to the hub. (Note that a hub is not the same as a non-blocking switch like the Sonnet GES-24 and GES-48, which readily support flow control.) |
