It is a scalable solution.

Around three or four customers of my company work with the product. If I consider Cisco's collaboration suite, Cisco UCS B-Series is used by a lot of clients because most of the collaboration applications under the suite work.

Until now, I haven't used the scalability feature of the product. I will have to use the scalability features of the product after five to six years of usage of the product.

If I consider the use of the solution in my company, I would say that there are around 600 endpoints in my organization.

There are 90,00,000 users of the solution.

Organizations can purchase extra devices or appliances and integrate them easily with Cisco UCS B-Series. It has good scalability. We have more than 3000 end users for it, and we plan to gradually increase the number of users.

From a scalability point of view, it is good. We did an upgrade for the memory, and it is stable and easy. We added some hosts in a cluster at the desk level. Scalability is fine.

I have been using it for the last ten years. In my current company, there are around 5,000 end users. 

But now, the users really want to move out of this solution. It's more difficult from a manageable point of view. We need a specific person with expertise to administer the environment. It totally depends on the cost. The users want to save costs, so they want to move to the cloud, either IBM cloud or Orange cloud. They want to move out; they don't want to expand further.

The B series is pretty scalable. You can have several chassis within an FI pair. Then you could have multiple UCS domains. Now, with the InterSite, you can have multiple configurations more so than the UCSB series with the InterSite managed solutions where you can have B series and you can have both UCS manager and InterSite yet you can't have both. With the UCS X series available, that's another game change.

Our customer base definitely intends to increase usage.

It's already made to scale, so you don't need to buy add-ons. In addition, you can use it to restore almost all your needs, not just for Cisco UCS B-Series. We have over 50,000 jobs running on our servers, which is valuable to our whole organization.

Cisco UCS B-Series is quite flexible and can expand horizontally and vertically, using cluster mode to support additional system loads. However, given the rise in AI and massive data, there is room for improvement in ensuring Cisco UCS B-Series remains AI-certified and capable.

I especially like the scalability aspect because, compared to the HP servers that we had before, those were rack-mount servers whereas the Blade is just a plug and play. If we need more computing power, we just bring a new Blade and plug it in and auto-conservation setup in the profiler takes over the new Blade and it's that easy. We are a team of three admins using this solution.

The scalability of this Cisco product goes without saying because it is what the B-Series was designed to do. You can always add in additional blade servers to your existing chassis. So the scalability is really good and something Cisco built into the product.

Cisco UCS B-Series is a scalable solution with a fairly advanced environment that can scale easily. It is not cheap, but it provides the ability to scale up in terms of computing, networking, and memory. Around 2,000 people are using the solution as our central computing. In terms of management, we're a small team of ten people working with the solution. The solution is being used daily in our organization.

I rate the solution ten out of ten for scalability.

None. Cisco UCS, to this day, has been the most easily scalable server product I have encountered. Hyper-converged solutions have potential, yet have not shown me that they are scalable at an enterprise level the way the B Series UCS are at this time.

Bob Whitcombe
Technical Sales Architect at a tech services company with 501-1,000 employees

UCS originally promised to support 40 chassis per fabric – that has now been scaled down to 20 – which limits users to domains of “just 160” physical server blades. This has not proven to be an issue or obstacle. The release of UCS Central provides software to manage an array of fabrics so we can scale to thousands of physical servers.

Early on, we encountered scalability issues – UCS was to support 40 chassis – but it only did 10, then increased to 20. 20 chassis (160 servers) is more than enough as Moore's law, increased CPU core count and higher network bandwidth all made for the ability to place more workloads in a pod than we were comfortable with. So, it rapidly caught up.

Cisco UCS scales rather well and while all other systems are online, therefore allowing for in-place upgrades and updates. The system provides great scalability and versatility in regards to system growths and business requirements. You can easily add additional chassis and blade servers with no impact to the systems running in production.
