Subject: Re: RAID Systems for LANs and RS/6000
Date: 15 Sep 92 15:55:54 GMT
Status: R

Regarding John Scoggin's request for information on RAID systems for
VINES, Storage Computer of Nashua, N.H. will be showing its new high
performance RAID 7 disk array platforms at the September Banyan Users
Meeting.  They work equally well with NetWare, the RS/6000 and the AS/400.

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.

(I haven't yet seen these RAID 7 disk array platforms in operation myself,
but expect to visit the Storage Computer booth at BUI.)

For further information prior to the Banyan User Meeting, the contact is
indicated to be John O'Brien, Director of Technical Services, at
Tel. 603-880-3005 or FAX 603-889-7232.
