Overview

N2225 and N2226 SAS/SATA HBAs

1

Overview

The N2225 and N2226 SAS/SATA HBAs are Serial Attached SCSI (SAS) host bus adapters (HBAs) that provide 
high-performance external storage connectivity for servers and workstations. The N2225 HBA provides eight lanes of 
12Gb/s SAS connectivity and is matched with eight lanes of PCI Express® (PCIe®) 3.0 8Gb/s performance. The N2226 
HBA provides sixteen lanes of 12Gb/s SAS connectivity and is matched with eight lanes of PCIe 3.0 8Gb/s 
performance. 

These HBAs are based on the Fusion-MPT™-architected LSI SAS 3008 controller that integrates the latest 
enhancements in PCIe 3.0 technology and 12Gb/s SAS technology. The HBAs have onboard Flash memory for the 
firmware.
