我们目前熟知的 RAID(独立阵列冗余)技术包括IDE RAID.SCSI RAID 以及刚刚兴起的 Serial ATARAID。这其中,IDE RAID 处于最低端,又称之为 PATARAID(即并行 ATA RAID).它广泛应用在低端的服务器上,目前,已经有相当多的低端服务器主板上集成了ATA RAID 功能,以满足服务器对硬盘性能的要求。不过,如果主板上没有提供 PATA RAID 功能,用户可以添加专门的 ATA RAID 控制卡来实现。尽管 IDE RAID 具有明显的价格优势,但在由于其数据处理工作仍旧需要侬赖于服务器上的处理器资源(也称为半硬半软方式),因此主要是用于低档服务器中。与此相反,SCSI RAID 面向高端的服务器,其特点是高性能与高成本。不过,目前市场上也仍旧存在一些
Our currently well-known RAID (Independent Array Redundancy) technologies include IDE RAID.SCSI RAID and the newly emerging Serial ATARAID. Among them, the IDE RAID at the lowest end, also known as PATARAID (Parallel ATA RAID.) It is widely used in low-end servers, there are a lot of low-end server motherboard has integrated ATA RAID function to Meet server performance requirements for hard drives. However, if the motherboard does not provide PATA RAID features, users can add a dedicated ATA RAID control card to achieve. Although IDE RAID has obvious price advantages, it is mainly used in low-end servers because its data processing still requires processor resources (also known as semi-hard and half-soft way) on the server. In contrast, SCSI RAID targets high-end servers, which are characterized by high performance and high cost. However, there are still some in the market today
