ATTO Technology UL2D, UL25 user manual Atto ExpressPCI UL2S adapter

ATTO ExpressPCI Ultra2 adapters unleash the power of Ultra2 SCSI by eliminating SCSI management overhead and increasing SCSI transfer rates, while providing an easy performance upgrade path for your existing SCSI-1, SCSI-2 and SCSI-3 drives. Bus Master capabilities allow ATTO ExpressPCI SCSI host adapters to transfer data directly between the computer’s RAM and the SCSI bus without using the CPU. This frees all the CPU’s processing power for running demanding applications.
