Summary:
If you’re looking for a shared-storage solution that
gives you some cross-platform access, RAID 1 protection, and 4 Gb data
flow, then Terrablock is a great value.
Target APPS:
Post facilities that need to improve workflow
What It Costs You:
8XS system, $9,990 USD; 12D system, $15,990; 24D system, $26,490 to start. (You also need fibre channel host cards on every computer.)
What’s Cool:
Easy to use through the simple Manager program; no need for a dedicated
IT staff; easy to install; 4 Gb throughput for heavy HD work; limited
cross-platform workflow
What’s Missing:
Parity RAID protection, which would use 20 percent of your drive space
vs. the 50 percent the system’s RAID 1 uses; file-level locking. Also,
volumes need to be unmounted, then remounted, to reflect changes made
by others.
Specs
8XS: up to eight users, 2TB to 3.2 TB of storage and handles compressed HD video streams; 12D: up to eight users, 3TB to 4.8 TB of storage and up to one stream of uncompressed 10-bit HD; 24D: up to 24 users, 6TB to 12TB TB of storage and up to three streams of uncompressed 10-bit HD

Our company AlphaDogs, a post-production studio in Burbank, CA, had
been looking for a shared-storage solution for more than three years.
What we needed was hard to come by economically—a cross-platform
system, with real-time protection, that was easy to install and
maintain, at a reasonable price point. Then we discovered Terrablock
from Facilis Technology, Inc.
Soon after we bought a Terrablock 24D system, which can accommodate up
to 20 users and up to two streams of uncompressed 10-bit HD, we landed
a contract to online and color-correct 60 half-hour episodes of a new
Learning Channel show. The post schedule was going to include four
shows per week. We knew we would need to use one of our lower-cost
rooms, in this case, an Avid Adrenaline room, to capture the
uncompressed media. We would then use one of our Avid Symphony rooms
for the finishing work.
Prior to this, we’d been using a fibre patch bay to move drive arrays
between rooms. By analyzing the amount of time it took to shut our
systems down, move patches and restart the systems again, we came up
with a dollar amount in lost operator and room time. A simple
spreadsheet showed us that covering the cost of the Terrablock, with
its improved efficiency, would be a slam-dunk.
Streams and Workflows
The scaleable Terrablock line starts with the 8XS system, which can
handle up to eight users, 3.2 TB of storage and handles video streams
up to compressed HD. The 12D can also handle up to eight users, 4.8 TB
and up to one stream of uncompressed 10-bit HD. The 24D system we
bought fit our in-house storage needs and studio size perfectly.
Terrablock is a volume-level system, which means only one user can have
write access to a volume at any given time. All other users can have
read access if they have permission. This isn’t perfect for all
workflows. If you need multiple users to be able to write to a drive,
you’ll need a file-level system like Avid’s Unity or Apple Xsan. This
wasn’t a problem for our workflow; volume-level control is ideal for
us. Plus, the Terrablock works at a fraction of the cost of Avid Unity
and without the networking complexity that comes with configuring Apple
Xsan.
Since we were already wired for fibre, the install was a snap. If you
don’t have that infrastructure, that will be your first step. Hire a
pro to do your wiring, as fibre cable and connectors can be finicky.
The good news for AlphaDogs is that Terrablock can use 4 Gb fibre,
which lets us capture and edit uncompressed 10-bit, 4:4:4 HD on our
Apple Final Cut Pro HD stations.
You’ll likely connect a few computers to the Terrablock server, as we
did at AlphaDogs, and use the Terrablock Manager program to create
users for each station. The program (see illustrations, top left) is
very simple to use. One warning: If you format mounted volumes, which
appear as raw local drives on your computer, for the Mac, you’ll need
MacDrive to use it on your PCs. If you format NTFS, you can read it on
recent versions of OS X but not write to it. We developed workarounds
to get data back and forth between our Mac-based graphics rooms,
Mac-based ProTools rooms and PC-based Avid edit systems.
