All versions of TurboSTORE/iX work with any hardware configuration supported by
the MPE/iX system.
When using the basic Store and Restore functionality available
in the fundamental operating system (FOS), the minimum hardware
requirement is at least one disk drive and at least one tape drive.
The tape drive can be a magnetic tape drive, DDS drive, or StorageTek
cartridge tape drive.
FOS STORE also allows you to store to more than one device
at a time, either serially or in parallel. When using parallel or
serial devices for a backup, up to 16 devices can be used in parallel.
Within each parallel device pool, up to 8 serial devices are supported.
Each parallel device will run as a separate process. Multiple processor
systems, therefore, will see an even greater increase in performance
when using parallel backups. A general rule is to use one less parallel
device than there are processors. For a four-way MP system, this would
mean three parallel devices.

NOTE: From MPE/iX Release 6.5 onwards, TurboSTORE/iX II and
TurboSTORE/iX 7x24 True-Online Backup do not support magneto-optical devices.

When using TurboSTORE/iX 7x24 True-Online Backup, you can
back up to and restore from disk files. For the best performance,
it is recommended that the store-to-disk file(s) be located on a
different device than the files being stored or restored. However,
this is not required. Storing to more than one disk file in parallel
is supported. Again, for the best performance, each parallel disk
file should reside on a different disk or different volume set.
Serial device "pools" are not supported for disk files.
Although Store allows you to use a variety of backup devices,
you cannot mix backup devices within a single backup. If you want
to use multiple devices for a backup, they must all be one type.
SCSI and HPIB DDS devices and SCSI and HPIB magnetic tape devices can
be used together, however. Disk files cannot be mixed with any tape devices.
For more details on configuring your system for maximum backup
performance, refer to the HP3000 900 Series Computer
System Configuration Guide. Your optimal hardware configuration
will depend on your backup requirements and type of system.
