The HPE ProLiant ML110 Gen10 4LFF Hot Plug CTO Tower Server – 872307-B21 is a flexible 4.5U single-socket tower server designed for small and medium-sized businesses, branch offices, remote offices, virtualization, storage, backup, and general-purpose business applications.
The ML110 Gen10 combines the expandability of the Intel Xeon Scalable platform with HPE enterprise management and storage capabilities. The 872307-B21 configuration includes a 4 × LFF hot-plug drive cage, allowing customers to use 3.5-inch SAS or SATA storage and expand the platform's internal storage as required.
This is a Configure-to-Order (CTO) server, meaning the base SKU does not define a particular processor, RAM capacity, storage drives, or RAID controller. These components can be selected separately according to the required configuration. HPE specifically lists the processor as not included as standard for the ML110 Gen10 CTO platform.
The ML110 Gen10 is a single-socket server based on the Intel C621 chipset and supports Intel Xeon Scalable processors.
Depending on the selected configuration, the platform supports processors from the Intel Xeon Bronze, Silver, and Gold families. HPE documents support for both first- and second-generation Intel Xeon Scalable processor options.
Examples of supported processors include:
- Intel Xeon Bronze 3104
- Intel Xeon Bronze 3106
- Intel Xeon Bronze 3204
- Intel Xeon Bronze 3206R
- Intel Xeon Silver 4108
- Intel Xeon Silver 4110
- Intel Xeon Silver 4114
- Intel Xeon Silver 4116
- Intel Xeon Silver 4208
- Intel Xeon Silver 4210
- Intel Xeon Silver 4214
- Intel Xeon Silver 4216
- Intel Xeon Gold 5118
- Intel Xeon Gold 5120
- Intel Xeon Gold 5122
- Intel Xeon Gold 5218
- Other supported Xeon Scalable options depending on configuration
Important: These are supported processor options for the platform; they are not included simply because the server has part number 872307-B21.

Memory
The ML110 Gen10 provides 6 DIMM slots and supports DDR4 ECC Registered DIMM (RDIMM) memory.
The six DIMM slots provide memory expansion capability for the single-socket platform. The actual memory capacity and operating speed depend on the processor and DIMMs installed.
HPE's QuickSpecs specifically identifies the platform as having 6 DIMM slots for RDIMM DDR4 memory.

Storage – 4LFF Hot Plug
The defining feature of 872307-B21 is its 4LFF Hot Plug drive configuration.
LFF = Large Form Factor, referring to the standard 3.5-inch drive format.
The server provides:
4 × 3.5-inch LFF Hot Plug Drive Bays
These bays can be used with compatible enterprise SAS and SATA hard drives and SSDs.
HPE documents that the 4LFF hot-plug configuration can be upgraded to 8 LFF bays using the appropriate additional drive-cage configuration.
Supported storage can 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 configuration.
Recommended Website Specification
Drive Bays: 4 × LFF Hot Plug
Storage: No Drives Included – Configurable
Storage Expansion
One major advantage of this configuration is its ability to expand internal storage.
The standard 872307-B21 chassis has:
4 LFF Hot Plug bays
With the appropriate additional HPE drive-cage hardware, the ML110 Gen10 platform can support:
Up to 8 LFF Hot Plug drives.
HPE confirms that the 4LFF configuration is upgradeable to 8 LFF.
This makes the server suitable for customers who need larger-capacity 3.5-inch HDD storage for backup, file servers, archival data, and other storage-intensive workloads.
Storage Controller & RAID
The ML110 Gen10 supports an embedded software RAID solution with 10 SATA ports or optional HPE PCIe Smart Array controllers.
Optional HPE Smart Array controllers provide hardware RAID capabilities for customers requiring more advanced storage management and performance.
Supported controller options include configurations from the HPE Smart Array family, such as:
- HPE Smart Array E208i-p
- HPE Smart Array E208e-p
- HPE Smart Array P408i-p
- HPE Smart Array P408e-p
The exact RAID controller should be listed according to the actual configuration of the server being sold.

Network Connectivity
The ML110 Gen10 includes an embedded:
HPE Ethernet 1Gb 2-Port 332i Adapter
This provides 2 × 1GbE Ethernet ports for standard network connectivity.
HPE lists the embedded 2-port 1GbE 332i adapter as part of the ML110 Gen10 platform.
Additional networking can be installed through the available PCIe expansion slots.
PCIe Expansion
The server provides:
5 × PCIe 3.0 Expansion Slots
These slots allow the ML110 Gen10 to be expanded with additional hardware such as:
- RAID controllers
- Fibre Channel adapters
- Additional network cards
- Storage controllers
- Supported GPUs
- Other PCIe expansion cards
HPE confirms five PCIe 3.0 slots for the ML110 Gen10 CTO platform.
HPE iLO 5 Management
The ML110 Gen10 includes HPE Integrated Lights-Out (iLO) for remote server management and monitoring.
HPE's platform includes:
- HPE iLO Standard
- Intelligent Provisioning
- HPE OneView Standard support
Optional licenses can provide advanced iLO functionality.
With iLO, administrators can remotely monitor server health, access management functions, troubleshoot hardware, and perform other administrative tasks.
Optical Drive Support
The ML110 Gen10 chassis provides an optical drive bay supporting an optional:
- SATA 9.5mm DVD-ROM
- SATA 9.5mm DVD-RW
HPE notes that the optical drive is optional on applicable configurations.

Optical Drive: Optional / Not Included
Power Supply
The ML110 Gen10 platform supports several power-supply configurations depending on the selected server build.
HPE documents ATX and Flex Slot power-supply options for the platform.
Because 872307-B21 is a CTO chassis, the exact PSU should be specified according to the actual configuration of your unit.
Recommended Website Specification
Power Supply: Configurable – Depends on Build
Cooling
The standard ML110 Gen10 configuration uses non-hot-plug, non-redundant fans.
HPE also provides a redundant fan kit, part number 869489-B21, for configurations where additional cooling/redundancy is required. HPE specifically notes certain configurations that require redundant cooling, including some high-performance SAS SSD and 15K SAS HDD configurations.
