HPE ProLiant DL380 Gen12 vs DL360 Gen12: 2U Expandability vs 1U Density

The HPE ProLiant DL380 Gen12 and DL360 Gen12 are the two workhorse dual-socket rack servers in HPE's Gen12 family, both built on Intel Xeon 6 processors, DDR5-6400 memory, PCIe Gen5 I/O, and iLO7 management. The only fundamental difference is form factor: the DL380 Gen12 is a 2U platform built for expansion, while the DL360 Gen12 packs the same compute into a 1U chassis for maximum rack density. This guide breaks down where the extra rack unit pays for itself and where 1U is the smarter buy.

The short answer

Choose the DL380 Gen12 when you need expansion headroom: more PCIe Gen5 slots, double the drive bays, support for double-width GPUs or large accelerator/NIC cards, and bigger cooling and power margins for sustained high-TDP workloads. Choose the DL360 Gen12 when rack space, power per U, and density are the priority and your I/O and storage needs fit in 1U, which covers most virtualization, HCI, and general enterprise compute. For the majority of buyers running VM farms with modest local storage, the DL360 Gen12 is the more economical pick; for storage-heavy, GPU-accelerated, or I/O-rich roles, the DL380 Gen12 is worth the extra U.

Where HPE ProLiant DL380 Gen12 wins

Significantly more PCIe Gen5 expansion for NICs, HBAs, DPUs, and accelerators
Up to 24 SFF or 36 EDSFF front drive bays for storage-dense and software-defined storage roles
Supports double-width GPUs for AI inference and visualization at the rack edge
Larger thermal and power envelope sustains the highest-TDP Xeon 6 SKUs under continuous load
Most flexible configure-to-order platform in the mainstream Gen12 lineup

Where HPE ProLiant DL360 Gen12 wins

Same dual-socket Xeon 6 compute and 8TB DDR5-6400 memory in half the rack height
Best cores-per-rack-unit density for VM and container consolidation
Lower power and cooling footprint per server in dense deployments
E3.S NVMe options deliver high IOPS in a compact 1U front bay
Lower acquisition cost for compute-centric workloads that don't need 2U expansion

Which one should you buy?

Maximum VM density per rack for virtualization or HCI

Pick HPE ProLiant DL360 Gen12. Full dual-socket Xeon 6 compute and up to 8TB of memory fit in 1U, doubling the servers you can stack in a rack when local I/O and storage needs are modest.

Software-defined or storage-heavy nodes (vSAN, Ceph, backup)

Pick HPE ProLiant DL380 Gen12. Up to 24 SFF or 36 EDSFF front bays give the raw capacity and spindle count that storage-dense roles need without external shelves.

GPU-accelerated AI inference or VDI at the rack edge

Pick HPE ProLiant DL380 Gen12. The 2U chassis has the slot width, cooling, and power to host double-width GPUs that won't physically fit in a 1U DL360.

I/O-rich roles needing many NICs, HBAs, or DPUs

Pick HPE ProLiant DL380 Gen12. Up to six PCIe Gen5 x16 slots plus OCP give far more expansion than the DL360's three x16 slots for high-bandwidth networking and offload cards.

General-purpose enterprise compute with tight rack and power budgets

Pick HPE ProLiant DL360 Gen12. For application, web, and middleware tiers that don't need extra slots or drives, 1U delivers the same Gen12 performance with a smaller footprint and lower cost.

Frequently asked

What is the main difference between the DL380 Gen12 and DL360 Gen12?

Both are dual-socket Intel Xeon 6 servers sharing the same Gen12 platform, DDR5-6400 memory, PCIe Gen5 I/O, and iLO7 management. The difference is form factor: the DL380 Gen12 is 2U for expansion (more PCIe slots, more drive bays, GPU support), while the DL360 Gen12 is 1U for maximum rack density.

Do the DL380 Gen12 and DL360 Gen12 use the same processors and memory?

Yes. Both support up to two Intel Xeon 6 processors and up to 8TB of DDR5 memory at speeds up to 6400 MT/s, so raw compute and memory ceilings are effectively the same. The 2U DL380 can sustain the highest-TDP SKUs more easily thanks to its larger cooling envelope.

Which server is better for GPUs?

The DL380 Gen12. Its 2U chassis provides the slot width, airflow, and power headroom to support double-width GPUs for AI inference, VDI, or visualization. The 1U DL360 Gen12 is limited to low-profile accelerators.

How much storage does each server support?

The DL380 Gen12 scales to roughly 24 SFF or up to 36 EDSFF front drive bays, making it the storage-dense choice. The DL360 Gen12 supports up to 10 SFF, 20 E3.S NVMe, or 4 LFF front drives in its 1U chassis.

Is the DL360 Gen12 cheaper than the DL380 Gen12?

For comparable compute, the DL360 Gen12 is typically the lower-cost and lower-power option because you're not paying for the extra chassis, slots, and drive cages. The DL380 Gen12 costs more but adds expansion you may need for storage, GPUs, or heavy I/O. We can quote both side by side for your exact configuration.

Which one should I pick for VMware or general virtualization?

For most virtualization and consolidation workloads where local storage and slot needs are modest, the DL360 Gen12 gives you the same Xeon 6 compute and memory in 1U, maximizing VM density per rack. Choose the DL380 Gen12 if your hosts need extra drives (for software-defined storage) or accelerators.

Are both servers TAA-compliant and available on GPC, SAP, and FAR?

Yes.
