HPE P47781-B21 MR416i-p PCIe Gen4 RAID Controller – In Dubai
Overview :
The HPE P47781-B21 is an internal storage controller designed for HPE ProLiant Gen11 servers, delivering hardware RAID functionality for SAS and SATA drive configurations. It is deployed by infrastructure teams and system administrators to manage internal storage arrays with data redundancy, improved I/O performance, and centralized control at the hardware level.
This controller operates over a PCIe Gen4 interface and supports 12 Gb/s SAS connectivity, enabling high-throughput data transfer between the controller and connected drives. It includes onboard cache to enhance read/write performance, particularly in transactional workloads and virtualized environments where consistent latency and throughput are required.
The MR416i-p connects internally to server backplanes and supports multiple drive configurations, making it suitable for rack-mounted and high-density server deployments. It is used in systems where reliable RAID implementation is required for application hosting, database storage, and general-purpose enterprise workloads.
Integration is aligned with HPE Smart Storage tools, allowing configuration, monitoring, and management of RAID arrays through standard server management interfaces. It supports multiple RAID levels to provide flexibility in balancing performance and data protection.
In practical deployments, this controller is used in virtualization hosts, application servers, and enterprise workloads requiring reliable storage redundancy. It is not intended for NVMe-only storage environments or software-defined storage architectures that bypass hardware RAID.
Typical Deployment Scenarios :
• RAID configuration for ProLiant Gen11 servers
• Virtualization hosts with hardware RAID storage
• Database and application servers requiring redundancy
• Rack servers with multi-drive SAS/SATA arrays
• Enterprise storage environments using internal RAID
