Did you know?
The N2125 SAS/SATA HBA provides high performance for storage connectivity for servers by integrating the latest enhancements in PCI Express and SAS technology, offering eight lanes of 6 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 N2125 SAS/SATA HBA supports SAS and SATA data transfer rates of 1.5, 3, and 6 Gbps per lane, and it enables maximum connectivity and performance in a low-profile form factor.
Rigorous testing of the N2125 SAS/SATA HBA by Lenovo through the ServerProven® program ensures a high degree of confidence in storage subsystem compatibility and reliability. Providing an additional peace of mind, the controller is covered under Lenovo warranty.
