Fujitsu S26361-F4042-L504 RAID controller PCI Express 3.0

The Fujitsu RAID Controller PRAID EP540i (model S26361-F4042-L504) with 4 GB cache and 16 × 12 Gbit/s SAS ports improves performance for storage‑intensive workloads such as databases and raises standards for speed and data security for internal storage drives. The controller supports up to 16 SAS/SATA drives, up to 4 NVMe PCIe drives, or mixed configurations of SAS/SATA and NVMe. It uses a Broadcom MegaRAID®–based RAID stack and integrates with Fujitsu ServerView RAID Manager and the Fujitsu server management concept. The card uses a PCI Express 3.0 host interface and is a full‑height PCI form factor compatible with a wide range of systems.

Advantages

The controller provides hardware RAID acceleration with support for RAID levels 0, 1, 5, 6, 10, 50 and 60, delivering improved read and write throughput for both 3/6/12 Gbit/s SAS and 3/6 Gbit/s SATA drives. NVMe support offers lower latency and higher IOPS when NVMe PCIe drives are used. Integrated management via ServerView RAID Manager and Broadcom MegaRAID® firmware simplifies configuration, monitoring and fault tolerance handling.

Suitable for

• Database servers and OLTP workloads
• Virtualization hosts and hyperconverged systems
• Backup and archival storage with RAID redundancy
• Mixed SSD and HDD storage arrays requiring high throughput

How to use

Install the full‑height PCIe card into an available PCI Express 3.0 slot on a compatible server chassis. Connect SAS/SATA backplane or NVMe PCIe drive connections according to the server hardware layout and the controller documentation. Use the Fujitsu ServerView RAID Manager or MegaRAID management utilities to create arrays, configure RAID levels, initialize cache settings and enable fault tolerance features. Follow standard procedures for driver installation and firmware updates as provided by Fujitsu.

Recommendations

For best performance, match drive speeds to expected workloads, enable appropriate caching policies, and use NVMe PCIe drives for latency‑sensitive, high‑IOPS applications. Regularly update firmware and monitor arrays via ServerView RAID Manager to maintain data integrity and availability.
