The Dell PowerEdge R770 and HPE ProLiant DL380 Gen12 are the two mainstream answers to the same requirement: a two-socket 2U rack server on Intel Xeon 6. On paper they converge, deliberately; both vendors build for the same competitive spec. The honest conclusion up front: for most buyers this decision is made by the operations stack around the server, not the server.

What actually decides it

Your management tooling. A team fluent in iDRAC scripting has real, accumulated automation that dies in a vendor switch, and the same is true in reverse for iLO shops. This is usually the whole decision, and it deserves to be.

The rest of the estate. Mixed fleets work fine technically, but spares, firmware baselines, and support contracts all get simpler when the fleet is one vendor. Matching what you have is a legitimate strategy, not laziness.

The quote in front of you. Both vendors price to win competitive deals. Getting both platforms quoted against the same configuration is the only way to know which one wants your business more this quarter, and it costs you nothing.

If you're starting from zero

No incumbent tooling, no existing fleet: then it genuinely is close, and secondary factors like chassis service ergonomics and support experience in your region carry the day. We configure and quote both; the R770 and DL380 Gen12 pages carry matched virtualization builds you can put head to head in one quote request.
