Testing Your Avid ISIS Connection
Before you begin using the Avid ISIS media network, you
should test the connection to your workspace to make sure
communication between your client system and the media
network is sufficient for the functionality needed by your
system. You can use the Avid PathDiag tool, which installs with
your client software, to test the read/write throughput, or the
rate that read and write operations are conducted between your
client system and a mounted workspace.
To test your workspace connection:
1. Select Start > Programs > AvidUnityISIS > PathDiag.
The Avid PathDiag tool opens.
2. Click the Setup button.
3. Click Custom Test.
4. Adjust the custom test parameters as follows:
- Path to Test — select a drive with a mapped Avid ISIS
workspace
- Duration (Minutes) — 2
- Loop — (optional)
- File Access Method — Automatically select
- Reads vs Writes — Writes, then Reads (Sequential)
- Transfer Size (KB) — 4096 for an Avid editing applica-
tion; 1024 for other Avid applications
- Transfer Rate (KB/S) — unlimited
- Max File Size (MB) — 100
- Use named common file for Reads — (optional)
5. Click OK.
6. Click Start in the PathDiag tool main window.
The following list indicates the results that reflect an optimal
connection for an Avid editing client on the media network:
• Average Read: 60 - 70 MB/s
• Average Write: 70 - 80 MB/s
• Peak Read: less than 5 MS/100
• Peak Write: less than 5 MS/100
In addition, results should plot along a smooth, stable line in the
Test Results graph, and they should not have peaks or spikes
that indicate variable performance within the media network.
The following illustration shows a healthy read/write test:
In this illustration, the test loops so that the Read results and
Write results fall to zero as the test alternates between Reads
and Writes. However, Reads and Writes plot consistently in the
Test Results graph and appear level over the course of the test.
If your results fall below optimal performance, you can check to
see if your User and Device bandwidth reservations are limited
(see the Avid ISIS Help). If your bandwidth requirements are
greater than the reservations set in the Avid ISIS Management
Console, your Avid ISIS administrator can adjust the limits.
These results represent guidelines for Avid-qualified systems;
performance on your system might vary. If your Read/Write
results differ from those listed here by more than 5 - 10 MB/s,
see your Avid ISIS administrator.
Additional Functions
If you have the necessary privileges, you can also use the
Client Manager to resize workspaces and to specify client
bandwidth reservations, if any. See your administrator to
determine your account privileges and which settings are
correct for your site.
For more information on using the Client Manager, see the
Client Manager Help or the Avid ISIS 7000 Client User’s Guide
on the online library DVD-ROM.
