Has anyone built their own 10GigE probe? I'm imagining just doing the same thing
I've done for 1GigE: NICs from Intel, Cory Satten's Gulp, the fastest storage
array I can afford, and a SPAN port.
I've vaguely thought of making the primary storage SSD, to which Gulp writes,
then buying slow disk and using a cron job to copy files off SSD as fast as
possible. But I haven't actually tried this yet.
And I'm imagining that Cace will deliver a 10GigE version of TurboCap at some point.
Actually, CACE is going to start offering a 10G solution very soon. As a
matter of fact, in few weeks.
We'll offer the same three alternatives that are currently available for 1G:
- card alone
- appliance kit (card + optimized dump to disk software + remote
analysis software)
- turn-key appliance
Pricing will be extremely competitive.
Have any tips for me?
- don't use SSD drives. They are not that much faster when dumping a lot
of data sequentially, they have a shorter lifespan, and they are
expensive. If you need more disk performance, increase the number of
drives: it's much more cost effective.
- be sure to know what your bottlenecks are before designing the system
- be careful when you read the packets for analysis: unless you use
tricks, it will completely destroy the write performance.
