HPE ProLiant DL320 Gen12 Drives
Genuine HPE hot-plug drives for the HPE ProLiant DL320 Gen12, new and refurbished, tested before shipping. Five CTO chassis decide what fits — SFF, SFF/EDSFF, 4LFF, 12LFF, and GPU — so the cage you own sets the form factor before capacity does.
DL320 Gen12 Drive Specifications
- Bays by chassis: 8 SFF standard and 10 with the 8+2 cage; up to 10 SFF or 20 EDSFF on the SFF/EDSFF server; 4 LFF; 12 LFF; SFF and EDSFF cages on the GPU server
- Interfaces: SAS 24G and 12G, SATA 6G, NVMe Gen4 in U.3 SFF, and NVMe Gen5 in E3.S EDSFF
- Carriers: SFF Basic Carrier (BC) U.3, LFF Low Profile Carrier (LPC), and EDSFF E3.S EC1
- Endurance classes: Read Intensive, Mixed Use, and Very Read Optimized, the last only in E3.S NVMe
- Documented maximums: the maximum storage table lists 153.6TB from ten 15.36TB SFF SAS SSDs, 307.2TB from twenty 15.36TB EDSFF NVMe drives, and 288TB from twelve 24TB LFF HDDs
- Self-encrypting options: SED SATA, SAS, and NVMe drives, including FIPS 140-3 models
The chassis decides the form factor. The SFF server takes 8 SFF drives, or 10 with the 8+2 cage; the SFF/EDSFF server takes up to 10 SFF or 20 EDSFF E3.S; the 4LFF and 12LFF servers take LFF spindles. Match the cage you own before the capacity you want.
What drives fit the DL320 Gen12?
| Chassis | Drive form factor | Interfaces | Bays |
|---|---|---|---|
| SFF CTO server | 2.5-inch SFF Basic Carrier, U.3 | NVMe, SAS, SATA | 8, or 10 with the 8+2 cage |
| SFF/EDSFF CTO server | EDSFF E3.S EC1 | NVMe | 20 |
| SFF/EDSFF CTO server | 2.5-inch SFF Basic Carrier, U.3 | NVMe, SAS, SATA | 10 |
| 4LFF and 12LFF CTO servers | 3.5-inch LFF Low Profile Carrier | SAS, SATA | 4 or 12 |
| GPU CTO server | SFF Basic Carrier or E3.S EC1 | NVMe, SAS, SATA | 4 SFF or 8 EDSFF |
E3.S carries this platform's flash story: the 20-bay EDSFF front end is the densest option listed, on NVMe Gen5 drives. Our EDSFF E3.S guide covers the format, and the U.2 versus U.3 guide explains the SFF backplane side.
Choosing the Right DL320 Gen12 Drives
- Never mix interfaces, endurance classes, or drive types in one array — build each from identical drives.
- SATA needs the right controller. The backplane notes state SATA SFF drives are supported only with an appropriate controller, and Intel VROC does not support SATA.
- LFF capacity is stated two ways. The maximum storage table lists LFF HDD capacity at 24TB. The orderable drive list runs to 26TB in both SAS and SATA.
- Boot from the NS204i-u v2 rather than spending front bays on the OS — dual M.2 in hardware RAID1, and it occupies no PCIe slot.
- Plan cooling with the flash: high-performance fan kits are required with high-performance NVMe drives or certain backplanes.

DL320 Gen12 Drives FAQ
How many drives fit in a DL320 Gen12?
It depends on the chassis. The SFF server holds 8 SFF drives, or 10 with the 8+2 cage. The SFF/EDSFF server holds up to 10 SFF or 20 EDSFF E3.S. The 4LFF and 12LFF servers hold 4 and 12 LFF spindles; the GPU server holds 4 SFF or 8 EDSFF.
Does the HPE ProLiant DL320 Gen12 support 3.5-inch LFF drives?
Yes, in the 4LFF and 12LFF CTO chassis, on the LFF Low Profile Carrier. Note that the document states LFF capacity two ways: the maximum storage table lists 24TB LFF HDDs, while the orderable drive list runs to 26TB in SAS and SATA.
What is EDSFF E3.S and why does this server use it?
E3.S is the EDSFF ruler-style NVMe form factor. On the DL320 Gen12 it is what makes 20 flash bays possible in 1U, and the E3.S drives listed are NVMe Gen5 parts in the EC1 size.
What is the difference between Read Intensive and Mixed Use SSDs?
Endurance. Read Intensive drives suit read-heavy serving and cost less per TB; Mixed Use drives suit write-heavy databases and virtualization. The DL320 Gen12 list also includes a Very Read Optimized class in E3.S NVMe. Never mix classes in one array.
Can the DL320 Gen12 run NVMe drives without a RAID controller?
Yes. Intel VROC provides CPU-based RAID for direct-attached NVMe, up to 8 direct attach NVMe bays with RAID 0, 1, 5, and 10 depending on licensing. It is disabled by default and does not support SATA drives.
Are HPE Multi Vendor SSDs genuine HPE drives?
Yes. Multi Vendor (MV) SSDs are HPE-qualified drives running HPE firmware, sourced from more than one flash manufacturer. They carry HPE part numbers and appear throughout the DL320 Gen12 listings.
