This guide describes how to set up and operate the Silicon Graphics® Origin™ Vault expansion option. This option has two formats: a standalone tower and an expansion enclosure that can be mounted in the Origin Rack or other Silicon Graphics rack.
Accommodating six single-ended Fast-20 (Ultra) SCSI 3.5-inch disk drives and one full-height or two half-height single-ended SCSI-2 5.25-inch drives, the Origin Vault expansion option provides additional I/O for the Origin200™ (with a SCSI option PCI card), Origin2000™, or Onyx2™ system.
Both the tower and rackmountable enclosure formats are available with single-ended or differential 3.5-inch drive interfaces; in the differential version, two external connectors are provided so that the option can be daisy-chained to another Origin Vault option, or connected to a second host, such as for a dual-hosted configuration. The 5.25-inch disk drive bay is single-ended in either version.
This guide is written for owners and users of the Origin Vault expansion option. It presumes general knowledge of SCSI devices and of the host system with which the Origin Vault option is to work.
This guide contains the following chapters and appendix:
Chapter 1, “Features of the Origin Vault Expansion Option,” provides an overview of the Origin Vault option, explains versions, configurations, internal drive options, SCSI channels, and configurations, and gives operating guidelines.
Chapter 2, “Setting Up an Origin Vault Expansion Option,” describes how to set up an Origin Vault tower or mount an Origin Vault expansion chassis in an Origin Rack, how to install drives, how to cable the option, and how to power it on.
