HPE ProLiant DL380 Gen10 vs DL380 Gen10 Plus — Intel Xeon Scalable Gen1 to Intel Xeon Scalable Gen3 Upgrade Analysis

A side-by-side engineering and lifecycle comparison written for IT architects who have to decide between keeping the DL380 Gen10 running with ICD Care+ or refreshing to the DL380 Gen10 Plus platform. All specs come from HPE QuickSpecs and ICD’s live catalog. For teams refreshing mid-cycle — upgrade to Ice Lake without leaving the Gen10 chassis family you already operate.

At-a-glance specification table

CPU platform deep-dive

DL380 Gen10 ships with Intel Xeon Scalable Gen1/Gen2 (Skylake-SP / Cascade Lake). The DL380 Gen10 uses the LGA3647 socket (Xeon Scalable Gen1/Gen2); the DL380 Gen10 Plus moves to the LGA4189 socket (Xeon Scalable Gen3), so processors and heatsinks do not carry over.

DL380 Gen10 Plus runs Intel Xeon Scalable Gen3 (Ice Lake-SP). The generational jump is meaningful even if your workload never touches AI — per-core IPC is roughly 35-55% higher, memory bandwidth is 1.5x at iso-channel, and PCIe moves from Gen3 to Gen4. For compute-bound Oracle, databases, or HPC codes the Gen11 delta alone can justify the migration.

Memory subsystem (DDR4 to DDR4)

Memory is the single biggest platform difference. The DL380 Gen10 uses 3TB DDR4-2933 across 24 DIMM slots. The DL380 Gen10 Plus uses 8TB DDR4-3200 across 32 DIMM slots. Both generations share the same DIMM form factor, which simplifies carry-over on memory-heavy workloads.

Where memory frequencies overlap, carry-over is mechanically possible but HPE validation restricts mixed-speed banks — plan for a full DDR uplift if you want validated support. Memory for a fully populated DL380 Gen10 Plus (32 DIMM slots) is quoted per configuration, depending on capacity tier and memory condition.

Storage backplane + NVMe generation

The backplane generation is the second major delta. The DL380 Gen10 uses Smart Array P408i-a / P816i-a SR Gen10 (12G SAS); the DL380 Gen10 Plus uses Smart Array P408i-a / MR416i-a transitional. Drive carriers between the two generations are mechanically similar for 2.5″ SFF bays, but carrier part numbers differ by generation — order drives in the carrier HPE QuickSpecs lists for the target server, at the drive firmware level HPE supports on its controller.

NVMe E3.S (EDSFF) is the biggest architectural shift — DL380 Gen10 Plus in the Gen11/12 lineup supports dense EDSFF E3.S drives that were simply unavailable on DL380 Gen10. For object storage, Ceph, and high-IOPS Oracle ASM clusters this is transformative.

Power + cooling envelope

The DL380 Gen10 and the DL380 Gen10 Plus use HPE power supplies validated per platform. Order the supplies HPE QuickSpecs lists for the DL380 Gen10 Plus: a supply that physically fits the bay is not necessarily on the DL380 Gen10 Plus supported list.

Thermals matter: higher-TDP processors on the DL380 Gen10 Plus can require the high-performance fan kit listed in HPE QuickSpecs rather than the standard fans used on the DL380 Gen10. Size rack power and cooling with HPE Power Advisor for the exact configuration.

Smart Array vs MR controller line

DL380 Gen10 ships with Smart Array P408i-a / P816i-a SR Gen10 (12G SAS). DL380 Gen10 Plus ships with Smart Array P408i-a / MR416i-a transitional. Smart Array (SR) and Broadcom-based MR (MegaRAID) controllers are different families, each with its own firmware and management tools.

Operationally this matters for three reasons. First, cache protection: write-back cache is protected by an HPE Smart Storage Battery, and the kit (for example 871264-001 with a 145 mm cable or P01367-B21 with a 260 mm cable) depends on the controller and chassis, as listed in HPE QuickSpecs. Second, management: Smart Array controllers are managed with HPE Smart Storage Administrator (SSA), while MR controllers use HPE MR Storage Administrator and StorCLI. Third, arrays do not move between the two families: Smart Array and MR controllers write different array metadata, so data is migrated by replication rather than by moving the drives.

iLO generation differences

Out-of-band management evolves across this transition. DL380 Gen10 ships iLO 5. DL380 Gen10 Plus ships iLO 5. RESTful API parity exists between iLO 5 and iLO 6, but payload schemas changed — scripted remediation tooling (Ansible, Redfish, iLOrest) needs re-validation.

When to keep, when to upgrade

Keep your DL380 Gen10 and extend via ICD Care+ when: workloads are steady-state, IOPS ceiling is well below 12G SAS saturation, DDR capacity already meets 12–18 month forecast, and HPE’s EOSL date for your chassis still gives 24+ months of official support runway. ICD Care+ third-party maintenance picks up coverage at 40-60% below HPE’s post-warranty OEM rate, extending practical life 3–5 years past EOSL without a capital refresh.

Migrate to DL380 Gen10 Plus when: you need DDR4-3200 bandwidth for analytics/in-memory DB, your vCPU-to-physical ratio is already uncomfortable, your compliance program requires FIPS 140-3 attestation (iLO 6), or your consolidation roadmap calls for 2:1 or higher node consolidation.

ICD perspective + supply posture

If you are operating mixed fleets — common in banks, telcos, and manufacturing MES environments — ICD Care+ TPM covers both DL380 Gen10 and DL380 Gen10 Plus under a single contract, which removes the patchwork maintenance matrix most customers inherit after a multi-year refresh cycle.

Third-party maintenance bridge

HPE’s post-warranty pricing escalates sharply beyond year 5. ICD Care+ TPM holds coverage at 40-60% below HPE’s equivalent, includes on-site support with SLA levels set per contract, and supplies tested HPE parts. For fleets approaching EOSL that aren’t ready for a full refresh, Care+ is often the difference between a full fleet refresh in year 6 and a TPM contract covering years 6-10.
