Ultimate Dell EMC PowerEdge R7415 Review Top 1P 2U EPYC Today

[Patrick Kennedy]

Our Dell EMC PowerEdge R7415 review shows why this is the top 2U AMD EPYC single socket platform on the planet today. The PowerEdge R7415 sports an enormous capacity for high-speed networking, NVMe storage, memory capacity, cores counts, and just about every other aspect that makes a server good.

A few notes about this article.

It is funny how Dell EMC advertises heavily about how this model can save licensing cost for vSAN, but they ship you guys a server with a PERC H740P, which isn't supported/certified for vSAN (as it doesn't offer a pass-through mode). Even for ProxMox or any other ZFS type solution you probably should avoid this specific raid controller.

The iDRAC coverage (page 4) has the R7415's interface for the first and second images, but an R640 for the third image and a 'dual 28-core CPU server for the fourth image (possibly the same R640).

That’s funny about the PERC but I expect they think with the average performance of vSAN most people will pack it with NVMe drives to make it better than average.

A standard datacenter Windows license is 16 cores, are most people stopping here or going bigger ?
(I understand a lot of companies do not have such limitations so maybe that’s more than some and actually the majority)

 

[Patrick]

They also shipped us a single box not multiple so testing vSAN would have been hard. We also only had 2x NVMe SSDs.

That took me 2 days to get through. Good analysis in there.

So, NVMe hot plug only works on Dell servers, or are there other manufactures that managed to get that feature working?

 

[Patrick]

On the Intel Xeon side, it took several months between feature announcement and implementation. Now, every system I see has NVMe hot swap support on the Xeon side.

On the EPYC see https://www.servethehome.com/amd-epyc-v-intel-xeon-scalable-taking-stock-of-myths-july-2017/ under "PCIe is Not Always the PCIe You Expect". Vendors have slowly added this feature. I was at Tyan this week and they think that their latest BIOS update coming out will offer NVMe hot swap. I believe Supermicro does not (told it should be soon.) ASRR does not. The last time we tried Gigabyte it did not. HPE can. Some of the ODM models cannot.

Can confirm HPE DL380 Gen10 NVMe hotswap does work.
(Windows Server 2016 and RHEL7, didn’t bother testing anything old)
