The total ranking of a product, represented by the bar length, is based on a weighted aggregate score. For Views, Comparisons, Reviews, and Followers the score is calculated as follows: The product with the highest count in each area gets the highest available score of 17.5 points. Every other product gets assigned points based on its total in proportion to the #1 product in that area. For example, if a product has 80% of the number of reviews compared to the product with the most reviews then the product's score for reviews would be 17.5% (weighting factor) * 80% = 14. For Average Rating, the maximum score is 30 points awarded linearly based on our rating scale of 1-10. If a product has fewer than ten reviews, the point contribution for Average Rating is reduced (one-third reduction in points for products with 5-9 reviews; two-thirds reduction for products with fewer than five reviews). Reviews that are more than 24 months old, as well as those written by resellers, are completely excluded from the ranking algorithm.

What is most valuable?

The ability to scale from different clouds. At the moment, the scalability of the product is the number one thing that I saw. Right now, we're doing a private cloud, since we're government. In the future, we may want to look at public, but... more»

How has it helped my organization?

It has the potential to improve the way we function by having our different clouds be able to easily communicate back and forth. Right now, it takes a lot of work to do collaboration from our test lab, to our production, and to do anything... more»

What needs improvement?

Pricing and licensing could be improved as we are a government entity. Lower pricing could always help.

What is most valuable?

NSX gives us the ability to put our network, NSX, onto any network there is, which allows us not to have to go to the network team to create networks our VLANs for networks. We can just create all our networks right from the start. Whenever we want to spin something up, we just spin it up.

What needs improvement?

So far, what I've seen here at VMworld, it seems to be improving just the same line as everything else. It's going to expand, grow and grow and grow. It's going everywhere. It's not just going into "I'm using the V version of NSX," but it's going out to every environment. It's going out to all the clouds so that even if you have the V, you can also use the cloud... more»

One of the really good options of the SDN on DCN is the micro-segmentation. I would like to see it act more like a real firewall. You can use micro-segmentation, but you still need little VM firewalls to do complex filtering. If you could do... more»

What is most valuable?

Depicting the real user experience using an emulation rather than a simulation, that's one of the key points. The second is, we were able to reduce a lot of hardware calls where we used to have load generators across the globe.

How has it helped my organization?

We are able to use real-world scenarios from the global libraries with Network Virtualization pool support. It goes through about 1.3 billion libraries on any scenario, any bandwidth, and any network condition you could think of. It also... more»

What is most valuable?

NSX is extremely invaluable from the standpoint of security. It does have capabilities of micro-segmenting a network, being able to create smaller segments of various types of applications separated by various tiers. However, what it's mostly important for is being able to actually set security policies right at the interfacing virtual machine, which we haven't... more»

What needs improvement?

So the third-party marketplace is growing and growing for this product and being able to redirect traffic to them, to the third-party products in order to take advantage of those additional features, is wonderful. I think that one of the more important things to see better integrated into the NSX product would be an IDS/IPS type solution, which right now we're... more»

What is most valuable?

I sell to a lot of customers in the DoD. NSX has really become part of their ecosystem, especially for the tactical customers in the DoD. It's very important for them to have small footprints and have as much services in their servers, as possible. NSX has fit this role really well for them.

What needs improvement?

* Going through and getting more features sets from the routing protocols is definitely necessary for the future. * Being able to properly manipulate BGP * Getting multiprotocol BGP into the stack * A little bit better redistribution As a CCIE, I like to have all my tool sets, and there are some things which NSX is missing right now. It's missing some more... more»

What do you think of VMware NSX?

Valuable Features To be able to do the DR and SRM migrations from datacenter to datacenter, we're able to do them with SRM with VXLAN, with the NSX product. • Room for Improvement Just being more knowledgeable about the different functions. I think the product is fine. It's just learning more about the product, and how you can benefit from it, and what it's got to offer. • Stability Issues Very stable. We've had great success with it. It's a different mindset for the actual network folks that are used to building an old traditional way, but it's much faster to get things deployed with firewall rules. • Scalability Issues It's definitely scalable, however large, however small. We can bring people in with VDI desktops, with a control set already around that, to be able...

What do you think of Micro Focus Network Virtualization?

Valuable Features The most valuable features are flexibility and scalability. • Improvements to My Organization It allows us to update our infrastructure. We're moving out of a period of lack of investment into a period of investment, so it is allowing us to bring everything up-to-date; it essentially gives us the tools to do that. • Room for Improvement I can’t specifically think of any needed improvements at the moment. • Stability Issues Stability is fine, as far as I can tell. • Scalability Issues We haven’t had experience with scale yet. We're looking to scale out over the next year or so. • Customer Service and Technical Support Technical support is generally excellent. • Previous Solutions We realized that our technology was essentially out of date...

What do you think of VMware NSX?

Valuable Features Some of NSX's most valuable features are: Its distributed firewall The we can actually extend Layer 2 networking across datacenters, and also Layer 3 networking, which comes along with it. The routing and switching. • Room for Improvement They could branch out to the physical layer. Today, it's just the virtual layer, and they're starting to talk about the physical layer. We'd like to see the physical layer incorporated. • Stability Issues We've been using NSX now with Layer 2 stretching for approximately 10 months. We're getting ready to really ramp up the DFW, which is the distributed firewall piece, which we and our security team are very excited about. NSX is a very stable product. • Scalability Issues We've already scaled it across two...

What do you think of VMware NSX?

Valuable Features The most valuable part of NSX is it's very scalable and automated. Our change request time is really low. • Stability Issues For the most part, it's very stable. The only hiccup is sometimes during an upgrade, there are hurdles that you can have during that time, but overall it's very stable. • Scalability Issues Since we're almost 100% virtual, it's been very scalable for us. • Customer Service and Technical Support Sometimes, it can be difficult to get to a higher level engineer if you need to, but it takes some work to make that case. Usually it happens, but it's a little difficult. • Initial Setup It seems to be very straightforward. Usually a lot of it's handled by the installer. Yeah, very straightforward. As long as you read the design...

Valuable Features Security. Our Trend platform runs off NSX. • Improvements to My Organization We use the solution strictly for security. • Use of Solution Roughly six months. • Deployment Issues We didn't have this issue, but I would recommend to others looking at this solution to make sure that their hardware is compatible. • Scalability Issues It seems to be taking care of our whole environment. It seems to be pretty scalable. • Customer Service and Technical Support I have not used it, but my coworker has. Every time he talks to them, they're easy to get a hold of; very knowledgeable and they solve his issues right away. If you put in a trouble ticket, they contact you very quickly (in response).

What do you think of VMware NSX?

Valuable Features We can deliver the network that customers need quickly and safely. That is most important. • Room for Improvement There is one feature I'm finding with VMware which is special for us from IBM with JIRA routing protocols. This is in the future that they are planning, especially right now with our compatible AWS. AWS is good, understood, except for the software to improve, probably with Amazon right now doing this partnership. VMware and access are going to be improved for that. • Stability Issues It's totally stable, because right now it's running version 6.3. It's very mature. Even the versions with VMware 5.5, 6, and 6.5 are very stable right now. It's becoming more open to other environments, too. It's not only working with VMware, but also with Red Hat...
