Octel Overture 300 Load/Backup Device
The load/backup device is the floppy-disk drive, which permits online backup storage of critical
message server configuration information and software. It also offers a rapid and reliable means of
copying new software to the hard disk. The floppy-disk drive is also used to restore a message server
to normal operation when replacing the hard disk.
The floppy-disk drive is connected to the CPU by a cable to the front of the CPU.
Hard Disk Drives
Disk assemblies are plug-in, random access, read/write magnetic hard-disk assemblies, requiring no
adjustments or jumper configurations.
The Octel Overture 200/300 cabinet uses SCSI technology hard-disk drives that interface to a single
SCSI bus. This bus is controlled by the VCU. Disk drives are used for two functions:
- System/Voice disks store the operating message server programs, voice prompts, configuration
information, and voice messages. A portion of a system/voice disk is reserved for system
software, configuration data, and prompts. The remainder of the drive is used for voice message
storage.
- Voice storage disks store only voice messages.
Depending on capacity and redundancy requirements, each Octel Overture 200/300 contains one or
more hard-disk drives.
- The Octel Overture 200 message servers can contain from one to three hard-disk drives in slots
B2, B3, and B4.
- The Octel Overture 300 message servers can contain from one to six hard-disk drives in slots B3,
B4, C1, C2, C3, and C4.
The first disk drive is always a system/voice disk. If a second disk is installed, it is also a
system/voice disk. If additional disk drives are installed, they are voice disks only.
The maximum disk storage for an Octel Overture 200 message server is 540 hours of voice storage.
The maximum disk storage for an Octel Overture 300 message server is 1085 hours of voice storage.
Disk-storage space for recorded messages, names, greetings, redundancy and feature applications is
purchased in 5-hour increments. Storage hours are upgraded by Octel Customer Administration.
