PRAID EP520i

The Fujitsu RAID Controller PRAID EP520i with 2GB cache and 8x12Gbit/s SAS ports improves performance for storage intensive workloads such as databases and sets new speed and data security standards for internal storage drives. The new PRAID EP520i supports up to 8 SAS/SATA drives, up to 2 NVMe PCIe drives or a mixture of SAS/SATA and NVMe drives. NVMe is an interface with lower overhead, lower latency and drastically increased bandwidth and IOP's. The NVMe drive support will be available at a later date, but the SAS and SATA drives will benefit from the improved performance and higher cache size.The RAID stack is based on the Broadcom MegaRAID® and offers high data throughput, a comprehensive fault tolerance function and user-friendly management options.
