Most customers use the C-Series server to install VMware solutions. It's deployed in a data center to handle the computing. Some customers use bare metal. Others are virtual. I am certified in VMware, so I've done a lot of VMware solutions, like integration between physical and virtual networks.
The VIC card is the most important feature.
I started using C-Series Rack Servers in 2013. It was the M3 edition when I started. Today, it's M6.
The C-Series is a hundred percent stable because it uses an Intel processor with Samsung or Hynix RAM. Computing depends on RAM, CPU, and hard disk. The latest release has an AMD option, but I've never worked with it.
The C-Series is not designed to be as scalable. They are designed to have enough RAM and enough CPU on their own side. If you want scalability, it's better to choose the B-Series— the Blade Servers — because those are much more scalable with Fabric Interconnect.
Most of the time, the C-Series is a standalone server. However, if you're talking about scalability in terms of RAM and CPU, they are excellent because you can install three terabytes of RAM. which is more than enough.
I've never contacted Cisco support because I can solve issues on my own most of the time, but my colleagues say that Cisco support is one hundred percent reliable.
Obviously, when you have unusual issues, it's not fair to assume that the first line of support can solve your problem. They definitely need to escalate. It's not reasonable to expect that the first person you reach at Cisco can answer all of your questions, but when you are dealing with Cisco, you should be confident that they can help you.
Deploying a C-Series rack is straightforward. It comes in two flavors. You can deploy it the standard way or do it over Fabric Interconnect, which can handle the B-Series and C-Series together if you have the license. Cisco's CIMC is much easier to deal with than the HPE's iLO. One engineer is more than enough to deploy and maintain the solution.
The server itself isn't costly at all, but the CPU and the RAM can be pretty expensive. You can buy a UCS for $2,000, but the RAM and CPU can cost up to $80,000. The most expensive asset is the intel processor, but it depends on how many cores you want and the technology you want to use on your CPU, like Hyper-V, etc.
I rate Cisco USC C-Series Rack Servers 10 out 10. If you plan to buy a C-Series, you should be clear about why you want to use it because the uses vary. different. Whether you're using Cisco, HPE, Dell or any other brand, it's essential to define your use case. For example, are you using it for a simulation graphics, calculations, etc.?
Depending on the use case, you might want to go with a small server with more CPU. Sometimes you need a light CPU with a powerful GPU. For example, if we have a C-Series with four CPUs at the same time, or we have a server that's handled two CPUs at the same time—the purpose is crucial.
C-Series is good enough compared to other competitors like HPE and the other ones. The HPE C20 is one unit and has a lot of RAM support, but the C-series is number one, in my opinion.
