High-performance servers have powered secure database analytics and flexible virtualization

The processing power and computing power are very good. Even with the Xeon Gold processor, it is performing very well without any issues. After migrating to these servers, we reduced the number of cores or CPUs from our infrastructure level. However, it is still not reaching the threshold limit of CPU usage. The bandwidth handling capability as well as computing capabilities are excellent. Day by day, Dell is enhancing and releasing new models and new Dell PowerEdge C- Series systems with new computing capability CPUs from Intel. These types of compatibilities are getting evaluated, and I am keeping my eye on that aspect so that when new technologies and new areas emerge, we can buy new hardware to migrate and host our other applications. Dell PowerEdge C- Series advanced security features are noteworthy. My applications are running without any issues, without any hacking or data leakage. Our security team and gateway firewall teams are always concerned about security, and I have peace of mind. Of course, Dell PowerEdge C- Series security features are helping us improve that. The hardware design is getting more and more powerful day by day. Whenever Dell releases new things, it is getting compatible with our different types of Gold, Platinum, Intel Xeon, and AMD type of CPUs. Dell PowerEdge C- Series handles L2 and L3 cache capabilities, caching capabilities, memory computing capabilities, and the NVMe RAM type also improves performance. The OS level hardware also has this type of NVMe type of high-speed storage implemented on that hardware. The hardware is getting improved day by day. Dell PowerEdge C- Series storage is used in our data center, but I am not concerned about that because it is not used in my division. Although I am part of that organization, in my division, I am not using that.

"The is an annual license cost to use the Lenovo Flex System. If the price was less expensive and flexible overall and for additional features, our customers would be happier."

"The 14 blade server allows significant room for upscaling before having to invest in another chassis. You would have to purchase another chassis much sooner in the case of an eight or nine blade server."

"We have the whole maintenance for the 3 years, starting the deployment. We also have the VMware license for 3 years and I think we have another license to buy. There are no additional costs besides licensing."

"The price is interesting. I am able to quote a client based on their needs and offer them either Lenovo or Dell."
