HPE ProLiant DL345 Gen10 Plus Storage Controllers
Genuine HPE storage controllers for the HPE ProLiant DL345 Gen10 Plus, new and refurbished. Three families cover it — Smart Array SR Gen10 for SAS 12G, plus MegaRAID and SmartRAID Gen10 Plus for tri-mode NVMe/SAS — all over an embedded AHCI/SR100i software RAID controller.
DL345 Gen10 Plus Storage Controller Specifications
- Embedded: every model has an embedded controller running in AHCI or HPE Smart Storage SR100i Gen10 Plus mode, with software RAID for up to 8 SATA or 2 U.3 NVMe drives
- Smart Array SR Gen10: Essential E208i-a, E208i-p, and E208e-p, no cache; Performance P408i-a and P408i-p at 2GB, P408e-p at 4GB external, and P816i-a at 4GB with SmartCache over 16 internal lanes
- Tri-mode: MegaRAID MR416i-a and MR416i-p with 4GB cache, MR216i-a and MR216i-p without, all x16 lanes at 12G; SmartRAID SR932i-p at x32 lanes with 8GB wide cache and SR416i-a at x16 with 4GB, both 24G
- Boot: the HPE NS204i-p NVMe PCIe3 x8 OS Boot Device — UEFI required, not supported in Legacy Mode
- Cache protection: the P816i-a, P408i-a/-p, P408e-p, SR932i-p, SR416i-a, and MR416i-a/-p each require the 96W Smart Storage Lithium-ion Battery or the Smart Storage Hybrid Capacitor — one per server
Order cache protection with the controller. Every cached controller here — P816i-a, P408i-a/-p, P408e-p, SR932i-p, SR416i-a, and MR416i-a/-p — requires the 96W Smart Storage Lithium-ion Battery or the Smart Storage Hybrid Capacitor, and a server takes a maximum of one. The cache-less MR216i models need neither.
Which RAID controller does the DL345 Gen10 Plus use?
| Controller | Form factor | Cache | Best for |
|---|---|---|---|
| Smart Array E208i-a / E208i-p / E208e-p | Modular, PCIe | None | Entry 12G SAS, external SAS |
| Smart Array P408i-a / P408i-p | Modular, PCIe | 2GB | Mainstream protected SAS/SATA arrays |
| Smart Array P816i-a | Modular | 4GB, SmartCache | 16 internal lanes; 12LFF and expander builds |
| MegaRAID MR416i-a / MR416i-p / MR216i-a / MR216i-p | Modular, PCIe | 4GB or none | Tri-mode NVMe/SAS 12G |
| SmartRAID SR932i-p / SR416i-a | PCIe x32, modular | 8GB wide, 4GB | Tri-mode NVMe/SAS 24G, largest arrays |
Placement matters as much as the model. The -a controllers are modular and do not occupy a PCIe expansion slot; the SR932i-p needs an x16 electrical PCIe slot. The 12Gb SAS Expander Card is a 24 SFF option, sits in the default primary riser, and needs a P816i-a, P408i-a, or E208i-a.
Choosing the Right DL345 Gen10 Plus Storage Controller
- Order cache protection with the controller. Every cached controller needs the 96W Smart Storage Battery or the Smart Storage Hybrid Capacitor, and only one goes in a server.
- Tri-mode is what unlocks U.3. Without one, a U.3 cage runs NVMe U.3 on direct attach only; with one, the bays take SAS and SATA.
- Software-defined stacks want the cache-less MR216i-a or MR216i-p for passthrough.

DL345 Gen10 Plus Storage Controllers FAQ
Which RAID controllers are supported in the HPE ProLiant DL345 Gen10 Plus?
Smart Array SR Gen10 in Essential (E208i-a, E208i-p, E208e-p) and Performance (P408i-a, P408i-p, P408e-p, P816i-a) forms; MegaRAID Gen10 Plus MR416i-a, MR416i-p, MR216i-a, and MR216i-p; and SmartRAID Gen10 Plus SR932i-p and SR416i-a. The NS204i-p handles OS boot.
Do DL345 Gen10 Plus RAID controllers need a battery?
The cached ones do. The QuickSpecs state that P816i-a, P408e-p, P408i-a, P408i-p, SR932i-p, MR416i-p, MR416i-a, and SR416i-a each require either the 96W Smart Storage Battery or the Smart Storage Hybrid Capacitor, with a maximum of one per server.
What is the difference between -a and -p controllers?
Mounting. The -a models are modular and the QuickSpecs note they do not occupy a PCIe expansion slot; -p models are PCIe plug-in cards. An -e suffix means the lanes are external, for tape and enclosures.
Can the DL345 Gen10 Plus run RAID without a controller card?
Yes, within limits. Every model has an embedded storage controller that runs in AHCI or HPE Smart Storage SR100i Gen10 Plus mode, providing software RAID for up to 8 SATA drives or 2 U.3 NVMe SSDs. SR100i operates in UEFI mode only and supports Microsoft Windows Server only.
Which controller do I need for NVMe U.3 drives in the DL345 Gen10 Plus?
A tri-mode controller - the MegaRAID MR416i and MR216i models or the SmartRAID SR932i-p and SR416i-a. Without one, the QuickSpecs state that NVMe direct attach is used to support NVMe U.3 drives, and the U.3 cage then accepts NVMe only.
How does the DL345 Gen10 Plus boot without spending front bays on the OS?
The HPE NS204i-p x2 Lanes NVMe PCIe3 x8 OS Boot Device. It requires UEFI and is not supported in Legacy Mode.
