Important: The specifications above describe the manufacturer-documented CTO base platform. They do not confirm that a particular unit includes processors, RAM, storage drives, a Smart Array controller or a FlexibleLOM network adapter.
The 735151-B21 belongs to the BL460c Gen8 family but was introduced with configuration options tailored to Intel Xeon E5-2600 v2 processors.
It is not simply another part number for every BL460c Gen8 server. Its CTO configuration requirements differ from those of the earlier 641016-B21 base model.
The original configuration guide lists Intel Xeon E5-2600 v2 processor options, including models with different core counts, clock speeds and thermal requirements.
This allows a configured server to be matched to its intended workload, provided the installed components comply with HPE’s supported configurations.
Unlike the 641016-B21 CTO base, the 735151-B21 does not include the Smart Array P220i as a standard base component.
HPE documentation requires a suitable storage controller option to be selected during factory configuration. This is a particularly important consideration when purchasing refurbished hardware.
The server includes a FlexibleLOM connector, allowing a supported network adapter to be selected according to the enclosure’s networking environment.
The actual adapter installed in a particular unit must be confirmed with the supplier.
The BL460c Gen8 E5-v2 CTO platform supports selected Intel Xeon E5-2600 v2 processors. HPE’s original QuickSpecs document several options.
Examples include:
| Processor | Base Frequency | Cores | L3 Cache |
|---|---|---|---|
| Intel Xeon E5-2697 v2 | 2.70 GHz | 12 | 30 MB |
| Intel Xeon E5-2695 v2 | 2.40 GHz | 12 | 30 MB |
| Intel Xeon E5-2690 v2 | 3.00 GHz | 10 | 25 MB |
| Intel Xeon E5-2680 v2 | 2.80 GHz | 10 | 25 MB |
These are documented configuration options, not processors guaranteed to be included with the 735151-B21 being sold.
The appropriate processor choice depends on application requirements, thermal limitations, firmware and the rest of the installed hardware.
The server platform supports configurations using one or two compatible processors.
When using two processors, the installed models must meet HPE’s matching and population requirements.
Processor population also affects expansion capability. The second mezzanine slot requires the second processor to be installed.
For replacement projects, buyers should compare the exact processor configuration of the original blade with the proposed replacement.
The HPE BL460c Gen8 platform uses DDR3 server memory, with supported memory speeds and configurations depending on the processor and DIMM type.
The 735151-B21 CTO model was introduced with support for later Gen8 processor and memory options that were restricted on the earlier 641016-B21 CTO platform.
HPE’s configuration documentation includes supported 1866MHz SmartMemory options for appropriate E5-v2 configurations.
However, memory compatibility should never be determined by speed alone.
The CTO part number does not guarantee a particular memory capacity. A refurbished unit may contain different DIMMs from its original configuration.
One of the most important technical details of the HPE 735151-B21 is its configurable storage controller.
HPE’s official configuration documentation lists two relevant controller options:
| HPE Part Number | Storage Controller |
|---|---|
| 690164-B21 | Smart Array P220i/512 FIO Controller |
| 735062-B21 | Smart Array P230i/512 6Gb FIO SAS Controller |
These options are distinct from the CTO base itself. HPE required the appropriate controller to be selected during factory integration.
When purchasing a used or refurbished blade, buyers should confirm which controller is actually installed and whether its cache components are present and operational.
Storage controller compatibility can affect how existing drives and RAID configurations are recognised.
If the server will replace a failed blade, the controller model and configuration should be reviewed before transferring storage devices.
Do not assume that an existing RAID array can be moved between different controllers without compatibility checks and a verified backup.
The HPE 735151-B21 CTO platform provides two small form factor hot-plug drive bays for supported internal storage.
Depending on the configured storage controller and drive support, the system can be equipped with appropriate SAS, SATA or SSD devices.
Because this is a CTO model, the presence of drive bays does not establish that storage drives are included.
Before ordering, confirm:
For organisations maintaining legacy systems, obtaining a replacement with the correct storage configuration may reduce deployment complications.
The HPE 735151-B21 includes a FlexibleLOM connector for a supported network adapter.
HPE documentation describes the CTO model with 10Gb FlexibleLOM options, while later product identification also references 10Gb/20Gb FlexibleLOM capability.
Actual network functionality depends on the installed adapter and compatible enclosure interconnects.
The base part number alone does not identify a particular FlexibleLOM card or guarantee that one remains installed in a refurbished blade.
These checks are important when replacing an existing blade in a configured production environment.
The BL460c Gen8 CTO platform includes two PCIe x16 mezzanine expansion slots.
These slots support selected additional I/O options, subject to HPE’s hardware compatibility requirements.
The first mezzanine slot is associated with processor socket one, while the second requires processor socket two to be populated.
Therefore, the number of installed processors may affect which expansion options can be used.
Optional mezzanine cards are not guaranteed to be included with a 735151-B21 CTO base and should be confirmed individually.
The HPE ProLiant BL460c Gen8 includes the iLO Management Engine, using iLO 4 technology.
It provides remote server management features intended for monitoring and administering compatible ProLiant hardware.
Available functionality depends on the firmware version, installed licensing and management environment.
When deploying legacy Gen8 hardware, businesses should review management network security and firmware support before connecting the system to production infrastructure.
Older management interfaces may not meet current security standards, so access controls and appropriate network isolation should be considered.
The 735151-B21 is a half-height server blade designed for supported HPE BladeSystem c-Class enclosures.
It depends on the enclosure for shared power, cooling, management and interconnect infrastructure.
The blade cannot operate as a standalone rack server without the required enclosure.
| Component | What to Verify |
|---|---|
| Blade Enclosure | Exact model and supported blade generation |
| Enclosure Firmware | Compatibility with the BL460c Gen8 |
| Power Supplies | Adequate capacity for the installed processors and components |
| Cooling | Supported fan and thermal configuration |
| Interconnect Modules | Compatibility with installed FlexibleLOM and mezzanine adapters |
| Storage | Correct controller and drive configuration |
| Operating System | Support for the installed legacy hardware |
For original configuration guidance, consult the official HPE ProLiant BL460c Gen8 QuickSpecs.
Both part numbers belong to the BL460c Gen8 family, but their factory configuration requirements differ.
| Feature | HPE 735151-B21 | HPE 641016-B21 |
|---|---|---|
| Server Family | BL460c Gen8 | BL460c Gen8 |
| CTO Model | E5-v2 FlexibleLOM CTO | Earlier FlexibleLOM CTO |
| Processor Options | Xeon E5-2600 v2 series | Earlier supported Xeon E5-2600 options |
| Memory Options | Supports later documented memory options | Restrictions on certain 1866MHz and low-voltage memory options |
| Base Storage Controller | Controller selected separately | P220i with 512MB FBWC included in base |
| Drive Bays | 2 x SFF hot-plug | 2 x SFF hot-plug |
| Enclosure Family | BladeSystem c-Class | BladeSystem c-Class |
The storage controller difference is especially important. Buyers should not assume that the 735151-B21 includes the same standard controller as the 641016-B21.
Even within the same server generation, the exact CTO part number matters when identifying supported components.
Organisations maintaining established BladeSystem installations may use a compatible replacement blade to restore an existing server environment.
The replacement should match the required processor, memory, storage and network configuration.
Some businesses retain older server platforms to support applications that have not yet been migrated.
A correctly configured BL460c Gen8 may be relevant where the operating system, application and security requirements remain compatible.
Legacy blade servers can support controlled testing, application compatibility checks and infrastructure migration planning.
Such environments should be appropriately isolated where older firmware or unsupported operating systems are involved.
Keeping a compatible spare blade can support maintenance planning for existing enclosures.
However, the spare should be checked against the hardware and firmware requirements of the intended deployment.
A New or unused legacy CTO blade may be suitable for organisations requiring hardware that has not previously been deployed.
Because this is an older server platform, unused stock availability may be limited.
Buyers should confirm whether the unit is supplied as a barebone CTO base or includes configured processors, memory, storage and network hardware.
A Refurbished blade may provide a cost-effective option for maintaining existing BladeSystem environments.
However, the condition and configuration of individual refurbished units can vary.
Before purchasing, request details of the installed processors, RAM, storage controller, drives and FlexibleLOM adapter.
Customers should also enquire about hardware testing, firmware information, physical condition and applicable warranty terms.
Euroland IT Store can help confirm available condition options and supplied specifications before an order is placed.
For a configurable enterprise server, part-number accuracy is only the first step.
Before replacing a blade server, review the complete hardware configuration and surrounding infrastructure.
If existing drives or RAID arrays are being transferred, verify controller compatibility and ensure that suitable backups are available before making changes.
Businesses maintaining several HPE ProLiant generations may also require other blade servers and replacement components.

HPE 735151-B21 is the ProLiant BL460c Gen8 E5-v2 FlexibleLOM Configure-to-Order server blade. It is designed for compatible HPE BladeSystem c-Class enclosures and can be configured with supported processors, memory, storage and network options.
Not necessarily. The part number identifies a CTO base platform rather than one fixed processor and memory configuration. Buyers should confirm the installed processors and RAM with the supplier.
The P220i is not included as a standard component of the 735151-B21 CTO base. HPE documentation lists the P220i and P230i as configurable controller options. Confirm which controller is installed in the supplied blade.
Both are BL460c Gen8 CTO blades, but 735151-B21 is the E5-v2 configuration with different processor and memory options. The earlier 641016-B21 includes a P220i controller with 512MB FBWC in its base configuration, whereas 735151-B21 requires a separately selected storage controller.
Euroland IT Store offers New and Refurbished enterprise hardware options, subject to availability. UK customers can enquire about the exact configuration, condition, warranty, pricing and delivery arrangements.
