ZKLWHýSDSHU ý 1 H W 6 H U Y H U ý $ F F H V V R U L H V By the time you’ve read this white paper, many of your questions about storage and controllers will have been addressed. Then the decisions that you make and the configurations that you select, as you evaluate server system choices, will meet your needs now and in the future.
ZKLWHýSDSHU ý 1 H W 6 H U Y H U ý $ F F H V V R U L H V Connectivity A SCSI interface is an independent and intelligent local I/O bus. Through this bus a variety of different devices and one or more controllers can communicate and exchange information.
ZKLWHýSDSHU ý 1 H W 6 H U Y H U ý $ F F H V V R U L H V Controllers Controllers (or adapters) are devices that manage the communication interface by adapting or bridging the data from one I/O bus to another. As an added benefit, controllers can also organize and protect the data stored on the disks through mirroring, duplexing and/or RAID techniques.
