INTEL PROCESSOR COMPATIBILITY

Post by workaccount » 2019/02/22 15:34:25

Hi all of you guys!
I need your help before spending money.
I have to choose between these 3 Dell Server:
R440
T440
T5820
I'd like installing Centos OS 7 on them...
ANYONE KNOWS IF INTEL XEON GOLD OR OTHER INTEL XEON PROCESSOR GOT PROBLEMS WITH THIS SYSTEM?
Thanks a lot!

Well a T440 is likely to be identical to an R440 but in a tower case rather than rackmounted. No idea what a T5820 is.

No-one can tell you for sure if it's going to work or not, even given a specific model number of machine as you can alter the parts list and conceivably add unsupported hardware. However, I did an install of CentOS 7 on 2 x R440s last weekend. Those are dual Xeon Gold 5118, 64GB RAM, H730P RAID controller and 4 x 250GB SSDs with 6 x 10Gbps and 2 x 1Gbps ethernet ports. Works fine.
CentOS 5 died in March 2017 - migrate NOW!
CentOS 6 goes EOL sooner rather than later, get upgrading!

T5820 is "Precision 5820 Workstation". One CPU. Skylake generation, just like current Scalable Golds. Known to work.
[TR]440 are "Server". Up to two Xeon Scalable CPUs.

Fact: Xeon E-2136 (Coffee Lake generation; newer than Skylake) is ok on CentOS 7.


There are three likely points that could affect compatibility:
* Architecture of CPU/Chipset. RHEL is effective at backporting support to their kernel(1).
* Scalability to multi-CPU, although I don't recall ever having a Linux issue there(2).
* IGP support. Not an issue on Xeon that has none.


(1) As said, there is already support for newer architectures.
(2) Some unmentionable commercial OS have paywall limits on cores.
