Ελεγκτής RAID HPE P47781-B21 PCI Express 4.0 SAS-3 SATA III 8 GB

The HPE P47781-B21 RAID controller is a PCIe Gen4 (PCI Express 4.0) storage controller compatible with SAS-3 and SATA III drives. Based on Broadcom MegaRAID technology, it supports multiple RAID levels (0, 1, 5, 6, 10, 50, 60) and provides an 8 GB cache to meet the needs of enterprise and data center environments that require reliable data protection and high throughput.

Advantages

The controller delivers high bandwidth and improved rebuild performance for RAID configurations, supports both RAID and HBA/pass-through modes for flexible deployment, and is engineered for mission-critical and virtualized workloads. It offers fast random write performance and reduced rebuild times compared with older generations, while maintaining compatibility with SAS-3 and SATA III storage devices.

Suitable for

• Enterprise servers and data centers requiring hardware RAID
• Virtualized environments using HBA / pass-through mode
• Applications demanding high random write IOPS and fast rebuilds
• Systems using SAS-3 or SATA III drives

How to use

Install the controller into an available PCIe Gen4 slot on a compatible server motherboard following the server and HPE installation instructions. Connect SAS-3 or SATA III drives to the controller using appropriate cables or backplanes, configure drive arrays in the controller BIOS/firmware utility or management software, and select RAID or HBA/pass-through mode according to your deployment needs. Ensure firmware and driver versions are up to date and perform a full backup before initial configuration.

Recommendations

For best results in enterprise and data center deployments, use certified SAS-3 or SATA III drives, keep controller firmware and drivers current, and monitor rebuild and health status through HPE management tools. Consider RAID level choice based on performance and redundancy requirements.
