HPE MegaRAID 416i-a RAID-controller 16 kanalen, SATA 6Gb/s / SAS 12Gb/s / PCIe 4.0 (NVMe), PCIe 4.0 x8 (P26279-B21)

The HPE P26279-B21 RAID controller is a server storage controller designed for systems that require hardware RAID support over a PCI Express x4 4.0 interface and SAS-connected drives. It provides multiple RAID levels—0, 1, 5, 6, 10, 50 and 60—to address a range of data protection and performance requirements, and is compatible with several HPE ProLiant Gen10 Plus server models including DL360 Gen10 Plus and DL380 Gen10 Plus. The controller is compact and lightweight, with a recorded weight of approximately 0.129 kg, and is intended for installation in systems that accept the specified PCIe form factor and wiring.

Advantages

The controller supports a broad set of RAID modes suitable for balancing redundancy and throughput across SAS drives. Its PCI Express x4 4.0 host interface enables higher bandwidth compared with earlier PCIe generations in systems that provide the matching slot. Compatibility with HPE ProLiant Gen10 Plus servers simplifies integration into existing HPE environments and enables use of server management workflows already established for those platforms.

Suitable for (tasks / use cases)

• Enterprise and SMB server storage requiring hardware RAID across SAS drives
• Systems where multiple RAID levels (0, 1, 5, 6, 10, 50, 60) are needed for different workloads
• HPE ProLiant DL360 Gen10 Plus and DL380 Gen10 Plus servers and other compatible HPE Gen10 Plus systems
• Environments that prefer a compact, low-weight RAID controller with a PCIe x4 connection

When it may not be suitable

This controller requires a compatible PCI Express x4 4.0 slot and SAS storage infrastructure; it is not suitable for systems that lack the appropriate PCIe slot, do not support SAS drives, or rely exclusively on NVMe drives without SAS bridges. The product listing does not include cache size, battery or capacitor backup details, or onboard RAID processor specifications, so systems that require those specific documented features should verify availability through official HPE documentation before purchase.

Key specifications

• Host interface: PCI Express x4 (generation 4.0)
• Supported RAID levels: 0, 1, 5, 6, 10, 50, 60
• Supported drive type: SAS (Serial Attached SCSI)
• Typical compatibility: HPE ProLiant Gen10 Plus servers (for example DL360 Gen10 Plus, DL380 Gen10 Plus)
• Weight: 0.129 kg

How to use

Install the RAID controller into a matching PCI Express x4 slot on a compatible server while following the server manufacturer’s service manual and static-discharge precautions. Connect the SAS backplane or SAS cables to the controller according to the server chassis layout. Configure RAID arrays using the server’s firmware-level storage configuration utility or HPE storage management tools during system POST or through the operating system with supported management software. Ensure firmware is updated to the recommended version for the target server model and validate the RAID configuration and drive health after initial setup.

What to consider before purchase

• Verify that the target server has a free PCI Express x4 4.0 slot and that the chassis and backplane are SAS-compatible
• Confirm compatibility with the exact server model and firmware level from HPE resources
• Check whether additional components such as cache backup modules or management cables are required for your deployment

Recommendations

Use this RAID controller in systems where SAS storage and hardware RAID are required, and follow HPE guidance for firmware, driver installation, and server compatibility to ensure stable operation. Regularly monitor RAID health and perform backups before making array changes.
