The Personal IRIS currently supports up to three internal SCSI storage drives, including disk, tape and floppy drives. For users who need more storage, Silicon Graphics now offers the IRIS File, a SCSI drive expansion chassis that allows users to expand their Personal IRIS. The range of expansion options for the Personal IRIS includes:
Additional Storage Capacity:
All of the following disk drives are available from Silicon Graphics for use in either Personal IRIS or the IRIS File. All are SCSI interfaced and can he used either as a system disk to hold system software and applications, or as an option disk to expand system capacity. Each disk drive includes the mounting brackets and connectors needed for easy user installalion.
Each of the following SCSI-interfaced tape drives for the Personal IRIS and the IRIS File can be used either to install software or back-up and restore files and applications. The 1/4" tape drives include the mounting brackets and connectors. System software, shipped to users on 1/4" tapes recorded at low density (60MB), can be installed using either a 60 or 150MB tape drive.
The following floppy drives are available from Silicon Graphics for use in both the Personal IRIS and IRIS File. Floppy drives for the Personal IRIS and IRIS File include the mounting brackets and connectors needed for easy user installation.
1.2 MB, 5.25 inch
The IRIS File has four disk slots and can house up to five SCSI devices (either four full-height devices or three full-height and two half-height devices). Serving as a SCSI bus extension to the Personal IRIS, the IRIS File gives users the freedom to add devices as needed. Since the SCSI interface is common to both the IRIS File and the Personal IRIS, users can custom configure any combination of SCSI devices to meet their computing needs. With the addition of the IRIS File, users can take advantage of the SCSI controller's full potential to support seven devices!

 A Personal IRIS and IRIS File fully configured can physically house up to eight SCSI drives. Four full-height and four half-height drives. However, the SCSI controller can support only seven SCSI devices.
 Some SCSI subsystems may require a particular release of the IRIX operating system. Please contact your Silicon Graphics sales representative for further details.
 The disk drives used with older Personal IRIS models may be unable to use the Drive Access Switch. Please contact your Silicon Graphics sales representative for further details.
