The disk contorollers use disk array technology to provide very fast throghput
and/or high data integrity either using disk mirroring, duplexing or most
interestingly what Compaq call data guarding.
Data guarding provides a mainframe like disk farm to PC users. The system
uses only 4 disks with one of them holding the error correcting data allowing
or a single drive to go down without the user loosing any data. Even better
when you replace the disk drive the data that should have been on it is
recreated. All this functionallity is built into the drive array controller and
does not need software support.
The machines cost from $15,999 (240Mb) to $25,999 (840Mb)
[10,995 (pounds sterling) to 14,995] for single processor 386.
Additional 386 boards cost arround $3,500 and all machines come with 4Mb
of memory. If you want more memory 32Mb of 4Mbit Dram will set you back
$21,999.
486 procvessor boards were not anounced on monday they will be when there
are some 486 chips that work. So there is no pricing as yet.
Also Compaq anounced a desktop 25MHz 486.
The twin processors can be used by Compaq's new version of OS/2 Lan manager
(lan man on one processor and an SQL server on the other) or SCO Unix
which provides true symetrical use of the processors.
