Introduction Did you know? Introduction The N2225 and N2226 SAS/SATA HBAs for System x® are low-cost, high-performance host bus adapters for high-performance connectivity between System x servers and external storage enclosures (JBODs), tapes, and RAID storage systems. The N2225 provides two x4 external mini-SAS HD connectors with eight lanes of 12 Gbps SAS. The N2226 provides four x4 external mini-SAS HD connectors with 16 lanes of 12 Gbps SAS. Did you know? The N2225 and N2226 SAS/SATA HBAs provide high performance for storage connectivity for servers by integrating the latest enhancements in PCI Express and SAS technology, offering eight lanes (N2225) or 16 lanes (N2226) of 12 Gbps SAS matched with eight lanes of PCIe 3.0 to eliminate performance bottlenecks and provide high data transfer rates for medium-to-large capacity server storage applications. The N2225 and N2226 SAS/SATA HBAs support SAS data transfer rates of 3, 6, and 12 Gbps per lane and SATA transfer rates of 3 and 6 Gbps per lane, and they enable maximum connectivity and performance in a low-profile (N2225) or full-height (N2226) form factor. Rigorous testing of the N2225 and N2226 SAS/SATA HBAs by Lenovo through the ServerProven® program ensures a high degree of confidence in storage subsystem compatibility and reliability. Providing an additional peace of mind, these controllers are covered under Lenovo warranty.
