Data Scientist Assistant at a financial services firm with 5,001-10,000 employees
Rack servers have supported traditional workloads well but now need better NVMe reliability
I don't have specific ideas for improvement regarding the most advanced x86 processor, as Cisco has already adapted to the latest version of the chip. However, I do consider hardware device compatibility to be a concern. Sometimes certain batches of servers have problems with NVMe disks. For example, with a 400 GB volume, there is an error, but with a 900 GB volume, it works fine. Despite the same form factor, the disk technology with the 400 GB capacity causes errors, while the 900 GB is fine. This issue affects the stability of customers using Cisco UCS C-Series Rack Servers products. Cisco UCS C-Series Rack Servers should provide more support for multi-socket machines. I am referring to four-CPU or eight-CPU configurations. Currently, Cisco UCS C-Series Rack Servers mostly supports dual-socket machines only. This means that when we reach quad CPU, they either don't have it or have it with limited support. I believe the quad-socket market is still viable.

Supports flexible hosting needs through seamless upgradability and strong monitoring capabilities
The most valuable features of Dell PowerEdge R-Series for me are the feature richness and the upgradability. I really love the way that it is so dynamically applicable for every situation, and they manage to have an all-in-one solution for every single situation. Dell PowerEdge has supported the growth and operational success of my company through its great compute power and price-to-performance ratio. Every time Dell is at the top of its game for us, and there is just no other brand for us that is able to reach that kind of price-to-performance ratio. Dell PowerEdge R-Series has features that specifically cater to the needs of my small company, such as iDRAC. The iDRAC system is a complete feature set for managing servers and hardware technically and monitoring-wise. It really fits in our system and our ecosystem, and monitoring-wise, it is excellent. They have all these sensors available via different protocols and end points, which I love, and the ability to manage and control everything via the iDRAC interface is just a welcome bonus. In our use case, Dell PowerEdge R-Series is very flexible. It is another computer which helps a lot because of the durability over time. They keep running, making scalability for getting more of those resources in our environment so easy.
