Your server comes with a rack-mounted CD-ROM or DVD-ROM drive.
As an option, you can order a DVD-RAM drive as a feature to replace your internal drive or to have it in addition to your internal drive. All optical drives are devices that multiple users can access concurrently.
The iSeries server supports both directly attached small computer system interface (SCSI) and LAN-attached optical media library devices. These devices are an excellent alternative to storing data traditionally kept on paper, diskette, microfilm, microfiche, and tape. Optical libraries are high capacity, random access devices that provide fast access to a large amount of data. In addition, optical storage provides permanent, long-term archive characteristics unmatched by other storage mediums.
The iSeries server supports attachment of the IBM® 3995 and 3996 Optical libraries as well as non-IBM optical library devices.
