HP公司近日宣布推出一种新型I_2O磁盘阵列控制器(Disk-Array Controller,DAC)为需要更高性能和更大吞吐能力服务器用户提供容量可伸缩的I/O系统,兑现了它在其基于Intel芯片的服务器中采用智能输入,输出(I_2O)结构的诺言。在此新型磁盘阵列控制器中,HP将I_2O技术粜成到控制器卡中并利用一个Intel i960作为单独的I/O处理器,以提高服务器的可伸缩性和性能。初步测试表明,这个I_2O DAC可望平均提高服务器性能80％。这个DAC还支持Low Voltage Differential(LVD)/Ultra2 SCSI标准(LVD:低压差动),可将SCSI的吞吐率提高到80MB/秒。 HP I_2O DAC代表了HP支持
HP recently announced the availability of a new I_2O Disk-Array Controller (DAC) for scalable I / O systems for servers requiring higher performance and greater throughput, delivering on its Intel-based Intel The chip’s server uses a smart input, output (I_2O) structure of the promise. In this new disk array controller, HP will I_2O technology into the controller card and use an Intel i960 as a separate I / O processor to improve server scalability and performance. Preliminary tests show that the I_2O DAC is expected to improve server performance by 80% on average. The DAC also supports the Low Voltage Differential (LVD) / Ultra2 SCSI standard (LVD: Low Voltage Differential) to increase SCSI throughput to 80MB / sec. HP I_2O DAC stands for HP Support
