Final Cut Pro X: Xsan Best Practices

Today Apple posted a short white paper "Final Cut Pro X: Xsan Best Practices."

KB article: http://support.apple.com/kb/HT5084
White paper: http://images.apple.com/finalcutpro/docs/Final_Cut_Pro_X_Xsan_Best_Practices.pdf

Excerpt from the intro:

This document is designed to help you determine the best way of working with a SAN, such as Xsan, to speed up creative work and eliminate copying files across networks or hand-carrying hard drives on multiuser projects.

Two common scenarios are described below.

The first scenario sets up Final Cut Pro X for multiple users who will share a single project and Event, with editing access limited to one user at a time. This is essentially a “check-in/check out” workflow—for example, two editors on day and night shifts, or an offline editor who hands off the rough cut to another editor in a finishing suite.

The second scenario sets up Final Cut Pro X for two workstations sharing the same media simultaneously. For example, one workstation might act as the media-importing station and as a secondary edit station. The other workstation might be used for editing only. In this scenario, both workstations can access and edit the same original imported media stored on the SAN volume.

As far as I can tell, this is just a description of how best to use the Xsan support added in 10.0.1. I don't see that 10.0.2 or 10.0.3 have any special features that are leveraged here.

The Xsan support described is pretty simple and not very different from that of Final Cut Pro 7 and prior versions.

Basically, Final Cut Pro X relies on an Event database that it must have exclusive write access to. It is located in a folder, usually with its related media, and can reside anywhere on the SAN (not just in a root folder) as long as it's not nested within another Event folder.

Solution 1, sharing a single project and Event, is done by using and writing the event and project to a single folder location on Xsan (initiated by the File menu command "Add SAN Location"). When one editor uses the File menu "Remove SAN Location" command, or quits FCP X, the project is closed, and the Event database is released and made available to another editor to open and have exclusive write access to. So there will be just one project file, which can be used by only one editor at a time.

Solution 2, sharing media, is done by each editor having their own event folder (with its own event database) on Xsan. The second editor will point at media in the first editor's folder, but will use the media by reference instead of by copying it to their own event folder. Each editor will have their own project file.

In a nutshell, the white paper makes it clear how to enable the limited functionality available. Unfortunately, what is telling is what is not addressed:

  • You can share media in a single location, but you can't have multiple editors ingesting to the same location. (You could with FCP 7, if you were careful about file names.)
  • You can't share a single project at one time (one person editing video, and one person editing audio within the same project storyline).
  • You can't ingest media and have it automatically pop up in another editor's workspace (as Avid has done for years).
  • When you share media, there is no sharing of metadata you may add to the media within your own event database. Markers, keywords, collections, etc., are all visible only to one editor, no matter who may be sharing the media.

So it's nice to see this documented, but unfortunately there do not seem to be any magical new capabilities for advanced sharing capabilities revealed. Time to get those feature requests in!

FCmeter Plus From Vicom

Vicom has introduced FCmeter Plus, a new Fibre Channel Host Bus Adapter with Vmeter built in. What's sexy about QoS management for Xsan built into an 8 Gigabit Fibre Channel connection? Vmeter can limit workstation I/O for some clients, reserving bandwidth for others. Vmeter also gives us administrators logging and troubleshooting options with greater detail than we would have simply looking at our switches and logs for clients.

Now, by unloading the work that Vmeter was doing onto a card, the whole process is a little more streamlined. If you haven't checked it out yet, look at http://www.vicom.com/FCmeter-Plus.php.

Xsan + SNFS: Capitalization May Lead to Data Loss

Apple has posted a knowledge base article warning that a specific combination of Xsan client and a StorNext controllers may lead to data loss. The entire article is below.

Xsan 2.3: Update to StorNext SNFS v4.2.1 controller to avoid data loss issue

Symptoms

Xsan 2.3 clients (running OS X Lion or Lion Server v10.7.2 or earlier) that access filesystems hosted by controllers that use StorNext SNFS version 4.2.0 may experience data loss when renaming files on StorNext-hosted volumes.

A file may be unexpectedly deleted when renamed to a new name which differs only in the capitalization of the letters; for example, when changing "test" to "TEST".

Resolution

  1. Update all StorNext FS controllers from version 4.2.0 to 4.2.1 or later.
  2. Perform an orderly restart of all StorNext filesystems:
    1. Unmount any StorNext volumes from all clients on the SAN.
    2. Stop the StorNext volumes.
    3. Start the StorNext volumes.
    4. Mount those volumes on Xsan client systems once again.
    5. Verify that the issue no longer occurs when renaming files.

Additional Information

This issue does not affect earlier Xsan client systems or SNFS software versions other than 4.2.0.

CatDV Installation Checklist

A number of organizations are looking at what to do now that Final Cut Server is no longer being sold by Apple. There are a lot more options to handle Digital Asset Management than there were when Final Cut Server was initially introduced, and each should be reviewed based on all the requirements your organization has.

318 has been doing a lot of work with CatDV recently and as such, we are starting to build a large library of assets for the product (scripts, SOPs, etc). We have built a checklist for the installation and planning of a CatDV asset management system. The checklist is a quick guide to server installation, worker nodes, client configuration, using SSL, watch folders, conditions, queries, conversations and processing. To download the paper, see the TechJournal at:

http://techjournal.318.com/xsan/318-catdv-installation-checklist

CatDV is only one of the many options that you have regarding asset management. But in many respects it is the product most closely aligned with Final Cut Server both in functionality and price. Nothing would make me happier than this thread resulting in other experiences with other products, so I look forward to what I hope is a lively discussion on this!
