1.2.1 CDA 7 Capacities
The CDA 7 is available with various numbers of disk devices and storage
capacities.
CDA 7 can host both system and user data. In a GCOS 7 environment, disk-
modules are 18 formatted capacity. The 18 GB physical disks have to be split into
two 9 GB logical disks. The larger capacity models are particularly suitable in a
shareable context with Open Systems.
Table 1-1 outlines the CDA 7 model capacities when the CDA 7 is attached to a
DPS 7000 system host. The capacities are presented based on the method of data
protection: RAID-1 Mirroring.
