Another good question to consider is, how deeply are security and anti-tampering features built in? With the advent of Gen 10 servers HPE is implementing this right down in silicon whereas the rest of the marketplace is still using firmware features to try to accomplish this. This is arguably too late in the process to be able to guarantee what BIOS code you are actually running, what back doors have been slotted in or what spyware ‘features’ have been embedded!
Also, look where HPE are going with Synergy. They have taken a huge architectural leap forwards and the roadmap is hugely impressive.
I don´t know in deep Cisco servers, but if you compares a HP and a CISCO with identical hardware (same chipset, processor, amount of RAM,..), the benchmark are very similar.
In my humble opinión, it is very important ask for the warranty and tech support. And most important: if you need someday add more hardware to your server, you must know before if you don´t buy it to the server manufacture, you loose the warranty.
It is very tipical some server manufacturer sell very cheap their machines but when you need to add more memory and/or hard drives, it is obligatory buy them to the server manufacturer... an very expensive.
I would suggest visiting spec.org as there is a wealth of information available there. The benchmarks are run by the vendors but within guideline and industry verified. There are many different benchmarks available through this site depending on what you are really interested in.
Depending on what kind of workload you are looking for, you can find some info. / results from www.spec.org. Since Cisco UCS and Proliant DL are commonly used servers in enterprise, there should be test results of various benchmark on these server models.
I have attached the URL’s. The SAP testing is most revealing for overall systems performance and scalability. The most recent certifications show Cisco UCS servers eclipsing their HPE counterparts by notable margins. Standard Proliant systems are lower in total lines processed than Cisco units, and you have to move up to the HPE Synergy line to beat lower end Cisco C240 servers. However, the higher end 4-way Cisco C480 handily beats Synergy.
