VAX clusters had shared disks from the beginning in 1983 (16 years
before this dubious patent).
Yes, but if you read the patent,
what they are patenting is adding caching to a VAX cluster, which historically
lacked a distributed block cache.
However, it's only software, and whilst
it's probably hard to implement, adding a cache is a fairly obvious idea. [ Reply to This | Parent | # ]

As the SCSI standard did allow multiple control nodes.
I ran a shared SCSI between Linux and Windows (to access a SCSI 2 tape backup
device). The only problem that showed up was that Windows couldn't handle a
remote bus reset... Other than that, there were no problems actually sharing the
tape.

Novell NetWare (Called Sharenet at the time) used read and write caching in
1983. Of course, the disk was internal to a server, but was effectively shared
by all client computers.[ Reply to This | Parent | # ]
