Optical system configurations

 

All systems include a rack-mounted CD-ROM or DVD-ROM drive that is ideal for program and data distribution. The CD-ROM or DVD-ROM drive is primarily intended as a program and data delivery device and, even though many users can potentially access it simultaneously, it can access only one media at a time. A DVD-RAM drive is available to replace the existing read-only drive or to be added as another internal drive. This drive can read CD-ROM or DVD-ROM media, and can read or write DVD-RAM media. The CD and DVD drives supported on the system cannot be used to write to CD-R, CD-RW, DVD-R, DVD-RW, or DVD+RW media. An optical media library is a device that contains at least one optical disk drive and may contain many optical cartridges. Optical media libraries can manage large numbers of optical cartridges and users. Optical media libraries connect directly to your system. A multiwire cable connects the library to an IOP or I/O adaptor card. Optical media libraries support all of the following functions:

• Hierarchical File System (HFS) application programming interfaces (APIs).

• Most integrated file system commands.

• Many i5/OS^® save and restore commands.

• Other LAN-connected systems can access the optical media libraries by using the integrated file system.
