Cùng tìm hiểu Storage Systems là nội dung chương 6 thuộc bộ bài giảng Computer Architecture sẽ giới thiệu tới các bạn Introduction; types of Storage Devices; Busses - Connecting IO Devices to CPU/Memory Interrupts etc, How is data transferred;. | Computer Architecture Chapter 6 Storage Systems Prof. Jerry Breecher CSCI 240 Fall 2003 Chap. 6 - Storage Chapter Overview 6.1 Introduction 6.2 Types of Storage Devices 6.3 Busses - Connecting IO Devices to CPU/Memory. Interrupts etc. How is data transferred. 6.5 Reliability, Availability and RAID Chap. 6 - Storage Introduction The Big Picture: Where are We Now? We will look at how devices (especially disks) are put together. We’ll look at how to connect IO devices to the CPU. And then we’ll look at RAID, the brainchild of Patterson and his buddies. 6.1 Introduction 6.2 Types of Storage Devices 6.3 Busses - Connecting IO Devices to CPU/Memory.

This is only one example of IO, but we will save networks, tapes, etc. for another course. 6.1 Introduction 6.2 Types of Storage Devices 6.3 Busses - Connecting IO Devices to CPU/Memory. Interrupts etc. How is data transferred. 6.5 Reliability, Availability and RAID Chap. 6 - Storage Disk Device Terminology Types of Storage Devices Purpose: Long-term, nonvolatile storage Large, inexpensive, slow level in the storage hierarchy Bus Interface: IDE SCSI – Small Computer System Interface Fibre Channel Transfer rate About 120 Mbyte/second through the interface bus. About 5 Mbyte/second off of heads. Data is moved in Blocks Capacity Approaching 100 Gigabytes Quadruples every 3 years (aerodynamics) Can be grouped together to get terabytes of data. Chap. 6 - Storage Disk Device Terminology Example: Seagate Cheetah ST3146807FC 147 .
