Description:
The Dell PERC H810 boasts dual-core PowerPC processors for efficient RAID operations. It supports eight external SAS or SATA ports, enabling connection to a significant number of storage drives. This controller is suitable for various applications, including database servers, streaming media environments, and general-purpose storage needs.
The PERC H810 offers a variety of RAID levels to cater to different requirements. RAID 0 (striping) provides improved performance but no redundancy. RAID 1 (mirroring) offers complete data redundancy but utilizes double the storage capacity. RAID 5 and 6 distribute data and parity information across multiple drives for data protection with better storage efficiency compared to mirroring. RAID 10 and 50/60 combine striping and mirroring for enhanced performance and redundancy.
The 1 GB NV cache further improves performance by buffering frequently accessed data. This cache is non-volatile, meaning it retains data even during power outages, ensuring minimal disruption during server restarts.
