We have scaled up from the InfiniStream 4000 to the InfiniStream 9000 model, which has worked fine. I haven't had any issues.

I am impressed with vSTREAM. We haven't used it yet. I am looking forward to scaling from the hardware instrumentation to the virtual instrumentation with vSTREAM. Hopefully, that will work well for us.

So far, so good in terms of scalability. We're running into a couple of issues with the packet flow switch being overrun in part of our data center, but we're just sending it too much traffic. It's a matter of recalibrating things. It seems scalable.

We have found the product to be scalable. 

The scalability has some limitations and quirks to it. I would like to be able to upgrade rather than replace the whole thing.

The scalability is good, but it comes at a cost. E.g., if you need 100 InfiniStream because you are sending gigs or terabytes of data to one InfiniStream, then you will have to purchase another InfiniStream, which are not cheap.

The scalability is very nice. I'm excited to get into the vSTREAMs for the virtual appliances.

I like the scalability.

It can be scalable. It just costs too much. With a company as big as ours, it gets too expensive to accommodate every single site.

It appears to be very scalable.

It is a great, architecturally designed product and very scalable for our solutions.

It can be scaled with the Multi-Mode TAP solution. We have it big and little sites, e.g., we have a site with 14,000 users and another site with about 3000.

Scalability is good. It seems to be very scalable for what we use it for.

To capture more with the solution that we bought, you have to buy another InfiniStreamNG, and there are only four ports in the back.
