Abstract
A technique is provided for mapping mass storage device addresses to mass storage devices mounted in a mass storage device mounting system. The mounting system may include a single type of chassis that may contemporaneously mount two sets of disk mass storage devices. One of the sets of disk mass storage devices may comprise disk mass storage device that have a first form factor (e.g., half height form factor), and the other set may comprise disk mass storage devices that have a second form factor (e.g., LP form factor).
Claims8
Method for assigning numerical addresses to mass storage devices mounted in a mass storage device mounting system, the system being able to mount different respective configurations of the mass storage devices, the system including a first chassis and a second chassis, each of the chassis being able to mount a combination of two types of mass storage devices, one of the types having a first form factor, the other of the types having a second form factor that is different from the first form factor, the method comprising:
- assigning a first subset of the numerical addresses to a first subset of the mass storage devices, the first subset of the mass storage devices being mounted in the first chassis;
- assigning a second subset of the numerical addresses to a second subset of the mass storage devices, the second subset of the mass storage devices being mounted in the second chassis;
- and
- the assigning of the subsets of the numerical addresses being based upon an actual configuration of the mass storage devices that is mounted in the mounting system and respective addresses assigned to the first chassis and the second chassis.
