The Fujitsu Flash Backup Unit Option (S26361-F4042-L110) is a high-speed, non-volatile memory module designed to protect in-flight data in Fujitsu server RAID arrays during power loss or system failures.
Key features include ultra-fast flash memory with a 64GB capacity, battery-free operation, automatic data preservation on power loss, and seamless integration with supported Fujitsu RAID controllers.
The unit is compatible with Fujitsu PRIMERGY rack and tower servers using RAID controller families like MegaRAID 900 and 930, as specified in the Fujitsu Server Integration Guide.
Installation involves mounting the unit into the dedicated RAID controller slot, connecting the onboard cable, and updating firmware via the ServerView BIOS extension for automatic recognition.
This flash backup unit offers 64GB of non-volatile storage, sufficient to commit all pending writes from the RAID cache to persistent memory within seconds.
By instantly committing cache writes to flash memory, the unit eliminates write-back delays during power events and sustains higher RAID write throughput under heavy I/O loads.
The unit uses error-correcting code (ECC) flash and self-test routines on every startup, ensuring all cached data is validated and safely stored without risk of corruption.
No, the flash backup unit is not hot-swappable and must only be installed or removed when the server is powered down and properly grounded.
The unit connects via a proprietary SATA-based flash interface designed by Fujitsu for full bandwidth integration with supported RAID controllers.
The S26361-F4042-L110 is rated for an MTBF of 1,500,000 hours at 25°C and full workload conditions, matching Fujitsu’s high-availability standards.
Fujitsu provides a three-year limited warranty covering defects in materials and workmanship, with optional extensions up to five years under the Fujitsu ServiceFlex program.
You can order through authorized Fujitsu resellers or the Fujitsu online shop, and check real-time stock levels via your Fujitsu partner portal or local distributor.
Yes, firmware updates are delivered via the Fujitsu ServerView Suite and applied automatically on controller reboot to ensure compatibility and performance enhancements.
No regular maintenance is needed; the unit is battery-free and self-monitoring. Periodic firmware updates and RAID controller health checks are recommended for optimal performance.
The unit draws less than 3W during normal operation and under 5W during write-commit cycles, contributing minimal additional load to the server power budget.
Comprehensive guides, white papers, and firmware downloads are available on the Fujitsu support website, with 24/7 hotline and online ticketing through the Fujitsu Service Portal.
