IBM storage subsystem setup

An IBM System Storage® DS8800 Model 951 is used as the storage subsystem.

DASD disk devices are used in the following configuration for the z/VM® Linux guest operating systems and data disks:

  • DASD Model 27, Model 54 and Model 128 directly attached to the guests
  • selection from two ECKD storage pools (storage pool striping enabled), taken from both internal storage subsystem servers
  • HyperPAV alias devices used

The details of the disk setup for each guest are listed in the pertaining topics later in this paper.

Note: FCP attached SCSI devices could also be used as disk storage.
