Associate System Engineer at SMS Global Technologies, Inc.
Easy to set up with good documentation and helpful support
I'm using it for a customer The packet flow switch is the most valuable aspect of the solution.  It's an easy product to set up. We can scale the solution if we need to. It's stable.  The documentation is well-written and quite useful. It's compatible with other products.  Under the pocket flow…

A user-friendly solution that is easy to install and improves visibility
I would like to see improvements made to the user guide. From my personal experience, it is helpful to see a list of steps describing what to do next in different situations. An example is what to do and what to back up in the case of certain types of failure. There are also cases where a customer can't understand specific features. Enhancements to the user guide would be helpful for this. More features for network fragmentation would be helpful.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It is very rock solid. We hardly have any hardware issues."
"The tool has the ability to look back within a month's data. It is very easy to navigate within the tool and troubleshoot the problem, compared to other solutions that we've used in the past."
"An issue that used to take days is now fixed within minutes to an hour."
"It has cut our troubleshooting down by days. Once we have a product in place, we show people examples of how it can streamline their troubleshooting process."
"I love the single pane of glass view. It makes it easier to not have to navigate everywhere. It allows more simplistic visibility, without having to go from tool to tool to tool, or from window to window to window."
"The solution has helped to increase application and network uptime, reduced our mean time to repair significantly for application and network issues, and cut our overall troubleshooting time from an hour down to five minutes."
"The technical support is really good. They will go above and beyond, if you are running into a problem. You can go to a sales engineer, who will engage technical support to help you out."
"This solution has cut our overall troubleshooting time, sometimes going down to a few hours over what might have taken one to two days to fully troubleshoot an issue, and it has helped to increase our application uptime as we try to keep the five nines."
"vSTREAM gives us better visibility and reporting about our network infrastructure, allowing for cost-optimization."
"vSTREAM gives us better visibility and reporting about our network infrastructure, allowing for cost-optimization."
"The generation of KPI-like information that feeds to the nGeniusONE (management) server is the most valuable feature."
"One of the valuable features is the packet decoding."
"Sometimes it took a month to troubleshoot something that we can now do within days."
 

Cons

"The technology goes end-of-life on us every year, which is why I am looking forward to vSTREAM. I don't like when devices go end-of-life on us so quickly. If we can get more of an advanced notice of when an end-of-life is brought up, because our certification process within the organization takes a while."
"The monitoring and reporting tool needs improvement. Users want more information, such as the level of detail when doing a packet analysis. They want more detail to be able to isolate down to a specific point."
"The NetFlow Collectors could handle more flows per minute."
"Only problems that we have had are fiber issues going into the TAPs or vSTREAMs, which are usually local site issues."
"I would like to see an improved level of stitching between IPs."
"It can be scalable. It just costs too much."
"The monitoring and reporting tool needs improvement."
"It's not able to communicate with our probes."
"Room for improvement exists in filtering in the packet decode."
"I would like to see improvements made to the user guide."
"I would say that this is not a scalable solution."
"I would like for it to have a smaller footprint of the virtual appliance and better performance."
"The stability is okay, but sometimes we see that the memory on the server is not 100 percent correct and we need to stop and start the software to have it reallocated again."
"I would like for it to have a smaller footprint of the virtual appliance and better performance."
 

Pricing and Cost Advice

"To capture more with the solution that we bought, you have to buy another InfiniStreamNG, and there are only four ports in the back."
"I would like it to be more scalable with less spend."
"The price is a little high."
"This product could be cheaper."
"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."
"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."
"Licensing is quite expensive."
