Hardware User's Guide
1
Overview
The N2225 and N2226 SAS/SATA HBAs for IBM® System x® 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 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.
