Preface
This manual is part of the documentation set for the CDA 7 family of products.
The CDA 7 is a very reliable high performance Integrated Cached Disk Array
(ICDA) designed for online data storage.
This manual describes CDA 7 maintenance and ORU replacement procedures.
This manual is intended for personnel involved in maintaining and repairing the
CDA 7 5330.
Versions of the Product
•For GCOS 7 systems, the CDA 7 5330 subsystem is available with two disk
technologies giving two different disk capacities: 9 GB and 18 GB.
9 GB refers to the formatted disk capacity. This is equivalent to an unformatted
disk capacity of 11.5 GB.
18 GB refers to the formatted disk capacity. This is equivalent to an unformatted
disk capacity of 23 GB.
This manual applies to both the 9 GB and 18 GB disk technologies. However, if
a section of text applies only to just one disk technology (9 GB or 18 GB), then
this is explicitly stated in the text. If no such indication is given, then the text
concerned applies to both the 9 GB and the 18 GB disks.
•CDA 7 5630 is available with 18 GB or 36 GB disk devices.
18 GB refers to the formatted disk capacity. This is equivalent to an unformatted
disk capacity of 23 GB.
36 GB refers to the formatted disk capacity. This is equivalent to an unformatted
disk capacity of 47 GB.
