Would anyone know where to find some good research reports on embedded
operating systems for RAID platforms? -- Michael.Willett@OFFICE.Wang.com

-------------------------------------------------------------------------

Regarding John Scoggin's request for information on RAID systems for
VINES, Storage Computer of Nashua, N.H. is currently showing its new high
performance RAID 7 disk array platforms at the September Banyan Users
Meeting.  They work equally well with NetWare, IBM systems, workstations,
the VAX, etc.

Standards-based, RAID 7 is designed for enterprise-wide computing and
overcomes performance limitations of earlier RAID architectures, providing
a  "real world sustained application performance improvement of 200% to
400%" and dropping the cost of storage to 16 cents/MB.  Their brochures
say they can "mix and match" up to 48 SCSI commodity (3.5 or 5.25 inch)
drives, up to 150 GB.  The RAID 7 disk array platforms come with an embedded
operating system and up to 12 SCSI-2 based host interfaces.  Besides servers,
Storage Computer's RAID 7 disk array platforms can connect to workstations
and midrange systems in addition to IBM's.  Multiple CPUs can be attached to
same disk array platform.

The RAID 7 platforms come with up to 256 MB of cache, eliminating any
reason for using performance-damaging CPU main memory disk RAM.

The drives are "hot plugable" for uninterrupted, transparent operation,
with a hot standby drive automatically replacing a failed drive.

There was a lot of activity yesterday at the Storage Computer RAID 7 booth
at the Banyan show as I walked by.  They were demoing what happens if a
drive goes down, showing the backup drive taking over.

For further information on Storage Computer's RAID 7 for the VAX, their
key contact is indicated to be John O'Brien, Director of Technical Services,
at Tel. 603-880-3005 or FAX 603-889-7232.
