Abstract
ERIK RIEDEL, SEAGATE RESEARCH 32 June 2003 QUEUE share your thoughts with us: Not Just a Bunch of Disks Anymore Storage Systems The sheer size and scope of data available today puts tremendous pressure on storage systems to perform in ways never imagined. T BANDWIDTH he concept of a storage device has changed dramatically from the first magnetic disk drive introduced by the IBM RAMAC in 1956 to today ™s server rooms with detached and fully networked storage servers. Storage has expanded in both large and small directions ”up to mulit-terabyte server appliances and down to multi-gigabyte MP3 players that fit in a pocket. All use the same underlying technology ”the rotating magnetic disk drive ”but they quickly diverge from there. Here we will focus on the larger storage systems that are typically detached from the server hosts ”the specialized appliances that form the core of data centers everywhere. We will introduce the layers of protocols and translations that occur as bits make their way from the magnetic domains on the disk drives and interfaces ” around the corner or around the world ”to your desktop. Let ™s start by looking at the internals of a modern desktop
