About the Fujitsu PRIMERGY Modular RAID Controller EP540i
The Fujitsu PRIMERGY Modular RAID Controller EP540i is a next-generation RAID-on-Chip (RoC) host bus adapter engineered for enterprise-class storage infrastructure. Implementing PCIe Gen4 architecture, the controller provides direct 12Gb/s SAS and SATA interface support, enabling efficient data movement across high-density storage arrays. The modular design integrates seamlessly into PRIMERGY M7 server platforms, supporting fault-tolerant RAID configurations (0, 1, 5, 6, 10, 50, 60) with dedicated on-card processors for RAID computation, eliminating host CPU overhead during storage operations.
Targeted at enterprises constructing large-scale backup repositories and tiered storage solutions, the EP540i addresses the architectural demands of modern data protection workflows. The controller supports mixed SAS and SATA device populations within unified arrays, delivering consistent performance for sequential and random I/O patterns. Hardware-based RAID acceleration ensures predictable latency characteristics essential for backup windows and recovery-time objectives in mission-critical environments.
Launched in Q2 2023, the EP540i represents Fujitsu's commitment to modular storage acceleration within the PRIMERGY ecosystem. Full compatibility with PRIMERGY M7 form factors, firmware management integration, and comprehensive monitoring via Fujitsu ServerView tools ensure operational consistency across enterprise deployments.
Ideal for
- Backup repository nodes supporting incremental and full backup cycles with RAID 6 protection across 12+ drive enclosures
- High-capacity NAS-style storage nodes for secondary data protection and long-term retention archives
- Tiered storage clusters combining fast SAS SSDs and SATA HDD capacity tiers within single PRIMERGY M7 chassis
- Disaster recovery appliances requiring consistent RAID-accelerated I/O performance across geographically distributed data centers
- Active-archive platforms serving regulatory compliance data retention with mixed-speed drive configurations
- Scale-out storage pods for virtualized backup infrastructure supporting concurrent snapshot and replication workflows
