The HP AJ941-04402 is a SAS (Serial Attached SCSI) I/O controller board designed for HP StorageWorks D2600 and D2700 disk enclosures. It functions as a storage interconnect module that manages communication between the disk enclosure and a SAS-enabled host server. This controller board enables high-speed data transfer, redundancy (depending on configuration), and reliable integration of JBOD (Just a Bunch Of Disks) storage systems in enterprise data center environments.
This is a legacy enterprise storage component commonly used in HP modular storage arrays.
