Dell R7625, R6625 and R6615 Lead Times: The HPE ProLiant DL385, DL365 and DL325 Gen11 Equivalents

Buyers are reporting long quoted lead times on specific Dell PowerEdge AMD builds, and the previous generation is getting harder to find. Here is how each Dell AMD model maps to its HPE ProLiant equivalent, with the CTO part numbers, so you can compare like for like before accepting the wait.

The question we are hearing most from hosting providers and enterprise IT teams this month is a simple one: the Dell AMD server we standardised on is quoting weeks out, so what is the equivalent we can get now? Dell has been open about the reason. On its latest earnings call the company reported a record AI backlog and said supply is constrained across servers and storage, with memory and NAND the biggest pinch points and spot shortages of CPUs and drives. The result is that specific PowerEdge R7625, R6625 and R6615 configurations are coming back with dates that do not suit a live project, and the previous generation R6515, R6525 and R7525 are scarcer still. Dell and HPE build directly comparable AMD EPYC platforms in the same form factors, so the practical answer is usually a like-for-like swap rather than a redesign.

Current generation: PowerEdge 16G AMD to ProLiant Gen11

Each Dell 16G AMD model has an HPE Gen11 counterpart with the same height, socket count and memory channel layout. All of these use the SP5 socket, DDR5 RDIMMs and PCIe Gen5.

• Dell's spec sheets for the R6615, R6625, R7615 and R7625 list 4th Gen AMD EPYC 9004 processors with up to 128 cores per socket and DDR5 RDIMM, up to 3 TB on the single socket models and 6 TB on the dual socket models.
• HPE's QuickSpecs for the DL325, DL345, DL365 and DL385 Gen11 cover both 4th Gen EPYC 9004 and 5th Gen EPYC 9005, with HPE quoting up to 160 cores per socket and 6400 MT/s memory when a 9005 processor is fitted.
• Memory maximums match: up to 3 TB per processor at one DIMM per channel across 12 channels, so 3 TB on the 1P platforms and 6 TB on the 2P platforms.
• Drive layouts line up closely. The R7625 tops out at 24 x 2.5-inch or 12 x 3.5-inch front bays; the DL385 Gen11 supports up to 24 SFF or 12 LFF at the front, plus EDSFF chassis options. The R6615 and DL325 Gen11 are both 1U units with up to 10 x 2.5-inch or 4 x 3.5-inch front bays.
• Dell's own 5th Gen EPYC platforms are the 17th generation R6715, R7715, R6725 and R7725, available since November 2024. If your Dell quote is for 9005 silicon, those are the models to compare against.

HPE CTO base part numbers are taken from HPE QuickSpecs (hpe.com and authorised reseller copies) and, for the DL345 Gen11 8LFF base, from UK distributor listings. CTO bases ship without processors, memory, drives or, in most cases, fans, so the base part number alone is not a working server.

Previous generation: PowerEdge 15G AMD to ProLiant Gen10 Plus

The EPYC 7002 and 7003 platforms are where the shortage bites hardest, because both vendors have moved new production on. These are DDR4 and PCIe Gen4 systems, which matters if you are extending an existing estate and want to reuse memory and drives you already own.

• The Dell models take 2nd or 3rd Gen EPYC (7002/7003) and the HPE models are built around 3rd Gen EPYC 7003, all with up to 64 cores per socket and DDR4-3200 memory.
• The DL325 Gen10 Plus v2 supports up to 1 TB of RDIMM across 16 slots, in line with the R6515. The dual socket R6525, R7525, DL365 Gen10 Plus and DL385 Gen10 Plus v2 all have 32 DIMM slots.
• If the target workload is licensed per core, a lower core count 7003 part in one of these chassis can still be the most economical answer, and refurbished stock does not wait on new CPU or DRAM allocation.

What to check before you swap

• Management and tooling: iDRAC9 and OpenManage on Dell versus iLO 6 and Compute Ops Management on HPE Gen11. Mixed estates work, but confirm your monitoring and firmware workflow covers both.
• Storage controller: PERC H755/H965i on Dell versus HPE MR and SR series controllers on Gen11. Plan RAID configs and drive carriers per vendor; drives are not interchangeable between Dell and HPE carriers.
• Hypervisor support: both platforms are certified for the main hypervisors, but check your exact version against the vendor's support matrix, especially if you are part way through a VMware exit.
• Memory: Gen11 AMD takes DDR5 RDIMMs from HPE's supported list. 4th Gen EPYC runs memory at up to 4800 MT/s and 5th Gen at up to 6400 MT/s, so match the DIMMs to the processor generation.
• Rack and power: chassis depth and PSU options are not identical between vendors. Check rail kits, PSU wattage and power cabling against your rack.

The ETON view

Our view is that a long lead time on one OEM is a sourcing problem, not a design problem. The Dell 16G and HPE Gen11 AMD platforms are built on the same EPYC silicon, with the same socket count, the same 12 channel memory layout and near identical drive options, so for most virtualisation, hosting and database workloads a DL325, DL365, DL345 or DL385 Gen11 is a straight substitute for an R6615, R6625, R7615 or R7625. HPE's Gen11 AMD range also takes 5th Gen EPYC 9005 in the same chassis, which gives a longer upgrade path than a 9004-only build.

We hold HPE Gen11 CTO base platforms in stock and configure them to your specification, so dispatch typically depends on components rather than on a factory slot. Depending on configuration it is often the more cost-effective route as well. The real constraint right now is memory and drives, so we quote those separately from the chassis and tell you where the time actually sits.

For the previous generation, refurbished DL325 Gen10 Plus v2 and DL385 Gen10 Plus v2 systems are the practical answer to a scarce R6515 or R7525, particularly when you can reuse DDR4 you already own. We are vendor neutral, so if the Dell build is genuinely the right answer we will source that too, and we buy back retired Dell and HPE AMD servers so the outgoing generation offsets the cost of the new one. Send us the Dell specification you are struggling to source and we will price the HPE equivalent alongside it.
