HPE ProLiant ML110 Gen10 4LFF Hot Plug CTO Tower Server – 872307-B21
Product Overview
The HPE ProLiant ML110 Gen10 4LFF Configure-to-Order Server – 872307-B21 is a single-socket 4.5U tower server designed for small and medium-sized businesses, remote and branch offices, and enterprise workloads that require a balance of performance, expandability, storage capacity, and manageability.
The ML110 Gen10 supports Intel Xeon Scalable processors, DDR4 Registered DIMM memory, PCIe 3.0 expansion, enterprise RAID options, hot-plug LFF storage, and HPE iLO 5 remote management. The 872307-B21 specifically provides a 4 × LFF hot-plug drive configuration.
Because 872307-B21 is a CTO SKU, the processor, memory, storage drives, RAID controller, and power-supply configuration can be selected according to the customer's requirements. The processor is not included as standard, and HPE specifies that hard drives do not ship standard with the base configuration
The HPE ProLiant ML110 Gen10 is a single-processor server using the Intel C621 platform. It supports both 1st-generation and 2nd-generation Intel Xeon Scalable processors, depending on the supported configuration. HPE lists processors from the Xeon Bronze, Silver, and Gold families.

Storage – 4LFF Hot Plug
The main feature of 872307-B21 is the 4LFF Hot Plug drive cage.
LFF = Large Form Factor, referring to the 3.5-inch drive format.
The server includes:
4 × 3.5-inch LFF Hot Plug bays
These bays support compatible SAS and SATA HDD/SSD configurations. HPE also states that the 4LFF configuration can be upgraded to 8 LFF hot-plug bays with the appropriate additional drive cage configuration.
Supported storage options include:
- 3.5-inch SAS HDD
- 3.5-inch SATA HDD
- 3.5-inch SAS SSD
- 3.5-inch SATA SSD
HPE states that hard drives do not ship standard with the CTO server.

Drive Bays: 4 × LFF Hot Plug
Storage: No Drives Included – Configurable
Maximum Storage Capacity
Depending on the installed drive cage and drives, the ML110 Gen10 platform supports substantial internal storage.
HPE lists configurations including:
- Up to 160TB with 8 × 20TB Hot Plug LFF SAS HDD
- Up to 160TB with 8 × 20TB Hot Plug LFF SATA HDD
- Up to 61.44TB with 8 × 7.68TB LFF SAS SSD
- Up to 61.44TB with 8 × 7.68TB LFF SATA SSD
These maximum figures apply to the broader ML110 Gen10 platform when the 4LFF configuration is expanded to 8LFF.
RAID & Storage Controller
The ML110 Gen10 provides the HPE Smart Array S100i SR Gen10 Software RAID as an embedded storage option.
The S100i supports:
- RAID 0
- RAID 1
- RAID 5
- RAID 10
HPE specifies that the S100i supports the embedded SATA ports and provides 10 SATA ports, with two ports leveraged for the M.2 option.
For customers requiring hardware RAID, optional controllers include:
- HPE Smart Array E208i-p SR Gen10
- HPE Smart Array E208e-p SR Gen10
- HPE Smart Array P408i-p SR Gen10
- HPE Smart Array P408e-p SR Gen10
The P408-series controllers are the performance-oriented options, while the E208-series controllers are positioned as essential RAID solutions.
Network Connectivity
The server includes an embedded:
HPE Ethernet 1Gb 2-port 332i Adapter
This provides 2 × 1GbE RJ-45 network ports as standard. HPE's QuickSpecs confirms the 332i adapter as the embedded network controller for the ML110 Gen10 CTO configurations.
Additional networking can be added through the available PCIe expansion slots.
PCIe Expansion
The ML110 Gen10 provides 5 × PCIe 3.0 expansion slots.
The slots provide different electrical configurations, including x16, x8, and x4 connections. HPE lists full-height expansion capability, with one slot supporting a full-height, full-length card and another supporting cards up to approximately 9.5 inches.
This allows the server to be expanded with:
- RAID controllers
- Network adapters
- Fibre Channel adapters
- Storage controllers
- GPU/accelerator options
- Other PCIe expansion cards
HPE iLO 5 Management
