HPE ProLiant DL345 Gen11 Drives

Genuine HPE hot-plug drives for the HPE ProLiant DL345 Gen11, new and refurbished, tested before shipping. This 2U platform is built for large-capacity storage — its CTO chassis run to 34 SFF, 20 LFF, or 36 EDSFF E3.S 1T bays.

DL345 Gen11 Drive Specifications

• Bay types by chassis: 8SFF, 24SFF, and 8LFF servers plus dedicated EDSFF and GPU CTO servers
• Maximums: 34 SFF drives, 20 LFF drives, or 36 EDSFF E3.S 1T drives
• Maximum internal storage: 552.96TB EDSFF NVMe (36 × 15.36TB), 522.24TB SFF NVMe U.3 (34 × 15.36TB), 261.12TB SFF SAS or SATA SSD (34 × 7.68TB), and 480TB LFF SAS or SATA HDD (20 × 24TB)
• Interfaces: NVMe Gen4 U.3 in SFF and NVMe Gen5 in EDSFF E3.S, SAS 24G, SAS 12G, and SATA 6G — including Value SAS SSDs
• Classes: Read Intensive, Mixed Use, Very Read Optimized (EDSFF E3.S), self-encrypting drives, Mission Critical 10K SAS SFF HDDs, and Business Critical 7.2K LFF spindles
• Carriers: the SFF and LFF cage kits are each listed as taking Basic Carrier (BC) drives, and the backplane compatibility table lists NVMe U.2 SSDs as not supported on every cage

It is U.3, not U.2. The drive cage compatibility table lists NVMe U.2 SSD as not supported on every DL345 Gen11 backplane and cage kit. SFF cages take SAS, SATA, and NVMe U.3 Basic Carrier drives; the 4LFF cages are SAS and SATA only.

What drives fit the DL345 Gen11?

The SFF cages are tri-mode, so one bay takes SAS, SATA, or NVMe U.3; the 4LFF backplane, mid tray, and rear kits are listed as SAS/SATA only, with NVMe shown as not supported. Our Gen11 drive compatibility guide walks the cage and backplane rules.

Choosing the Right DL345 Gen11 Drives

• Never mix interfaces, endurance classes, or drive types within one RAID array — build arrays from identical drives.
• It is U.3, not U.2: every DL345 Gen11 backplane and cage kit lists NVMe U.2 SSD as not supported — our U.2 vs U.3 guide explains the difference.
• Match the class to the workload: Read Intensive, Mixed Use, and the EDSFF-only Very Read Optimized group — our DWPD guide explains how the classes are rated.
• LFF is spindle territory: the LFF cages carry SAS and SATA only, which is where the 480TB raw maximum comes from.
• Boot from the NS204i-u rather than spending front bays on the OS — dual 480GB NVMe M.2 automatically configured as a RAID 1 mirror, externally accessible, and it does not occupy a PCIe slot.

DL345 Gen11 Drives FAQ

How many drives fit in a DL345 Gen11?
Up to 34 SFF drives, 20 LFF drives, or 36 EDSFF E3.S 1T drives, depending on which CTO chassis you have.

Does the HPE ProLiant DL345 Gen11 support U.2 NVMe SSDs?
No. The drive cage compatibility table lists NVMe U.2 SSD as Not Supported for every backplane and cage kit in this server. The SFF cages take SAS, SATA, and NVMe U.3 Basic Carrier drives.

Can the LFF drive cages take NVMe drives?
No. The 4LFF front backplane, mid tray, and rear cage kits are listed as SAS/SATA, with NVMe U.3 and NVMe U.2 shown as not supported.

What is the maximum internal storage of the DL345 Gen11?
The QuickSpecs list 552.96TB using 36 x 15.36TB EDSFF E3.S 1T NVMe SSDs, 522.24TB using 34 x 15.36TB SFF NVMe U.3 SSDs, and 480TB using 20 x 24TB LFF SAS or SATA hard drives.

What is the difference between Read Intensive and Mixed Use SSDs?
Endurance class. The DL345 Gen11 drive list groups SSDs as Read Intensive, Mixed Use, and - on EDSFF E3.S only - Very Read Optimized. Match the class to your workload and never mix classes inside one array.

Should I boot a DL345 Gen11 from a front drive bay?
The NS204i-u hot-plug boot device is the alternative: dual 480GB NVMe M.2 automatically configured into a RAID 1 mirror, externally accessible, and it does not occupy a PCIe slot. RAID 1 is preconfigured and no additional RAID can be applied.
