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.
