Storage Systems 郭大維 教授 Real-Time Disk SchedulingScheduling, Realtime Disk
The storage capacity of common disk drives is measured in gigabytes. When the disk is in use, a drive motor spins it at high speed. Most drives rotate 60 to 200 times per second. Disk speed has two parts. The transfer rate is the rate at which data flow between the drive and the ...

中断驱动I/O中，处理器代表进程发出I/O命令，并继续执行后续指令，当I/O模块完成工作时被中断。DMA技术由DMA模块控制主内存与I/O模块之间数据交换，处理器发送数据块传输请求给DMA模块，整个数据块传输完成后才会被中断。逻辑I/O与设备I/O之间的区别在于，逻辑I/O模块将设备视为逻辑资源，不关心实际...
We have applied these techniques to systems with large memories and potentially long disk queues. By viewing the entire buffer cache as a write buffer, we can improve disk bandwidth utilization by applying some traditional disk scheduling techniques. We have analyzed these techniques, which attempt ...
This application discloses a storage system, a storage device, and a hard disk drive scheduling method. The storage system includes M disk groups, a power supply system, and a contr
