Considerations Before Creating Virtual Disks
Different controllers have particular characteristics in the way they implement virtual disks. These characteristics may include use of disk space, limitations on the number of virtual disks per controller, and so on. It can be helpful to understand these characteristics before creating virtual disks on the controller.
The following sections describe controller information that applies to virtual disks:
- Virtual Disk Considerations For Controllers
- Problems Associated With Using The Same Physical Disks For Both Redundant And Non-Redundant Virtual Disks
- Virtual Disk Considerations On Systems Running Linux
- Number Of Physical Disks Per Virtual Disk
- Number Of Virtual Disks Per Controller
- Calculation For Maximum Virtual Disk Size

NOTE: In addition to
this document, review the hardware documentation that is provided
with the controllers. Reviewing the hardware documentation along with
this document may provide a better understanding of the controller
limitations.
