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.
