A Fibre Channel Analyzer Training webinar has been scheduled for December 1, 2010 at 1PM Pacific time, and it is free to attend by registering before the start of the webinar. You can get all of the details at the link below.
I’m putting this post up because almost everyone in the SAN Analysis world has been “stuck” using the same brands of expensive FC Analyzers for years, and its time to look at an alternative that works just a well (or perhaps better) and costs much less than the big name systems.
Now I understand being educated, trained, and having used a particular piece of equipment for years, and I know what its like to “become comfortable” with a particular system. But every now and then it’s good to see what the other guys have come up with.
Here are a few quotes from the site:
“You will be introduced to the challenges of analyzing 8Gb Fibre Channel technology and given practical techniques on how to capture and analyze Fibre Channel traces. When it comes to Fibre Channel analysis, a limited number of tools are available to perform the important function of debugging and analyzing your designs. … Today, the industry has a new player who has built an excellent tool that not only matches the capabilities of any current products, but adds advanced capabilities such as auto speed negotiation, increased buffer capture capabilities, advanced search functions, and other advanced features that will make your job easier.”
Register before the start date and please mention that you were referred from SANTrainingblog.com. Here is that link again:

SCSI Commands & Architecture Class Results
I just thought I would post the results of the SCSI training class that was held about a week ago. First I would like to thank the students – without them, this class could not have gone so well. Everyone had lots of questions about various SCSI related topics, including:
- How to interpret SCSI Command fields?
- What happens when a command doesn’t work?
- What are the SCSI Status responses that occur for different conditions?
- How do I decode SCSI Sense Data?
- How do I read or decode a SCSI analyzer trace?
- How can I read a Fibre Channel analyzer trace?
I know that last one may not seem like a “SCSI thing”, but when you are looking at SCSI FCP portions of the trace, we discover that 99% of the information is SCSI related. After all, Fibre Channel is just SCSI over another connection. I guess the same can be said if you are using iSCSI or SAS too.
I believe the high spot of this class, at least for me, was going over analyzer traces that helped to reinforce the concepts of the course. Some of these concepts were:
- How SCSI connections are made
- How to identify what Host (Initiator) and Device (Target) are involved in any command
- How to identify what status is for which command and
- When do we disconnect and reconnect.
At one or two points during the class, I even had some of the students “take control” of the presentation system so that everyone could see what was on their computer screen. And all of this was done without them having to leave their office, or in one or two instances, their home. Everyone used Voice over IP (VoIP), so that we could chat and answer questions in real time. I especially want to thank the students in the Eastern time zone for “working late” when we had to change the schedule. I hope that all of the students enjoyed their “bonus gifts” that were sent to them because of this change.
One last note: If you and a few coworkers would like to take this class, or one of the other SAN training courses offered, please contact me and I will try to arrange a course that is convenient for YOUR schedule.
