Greetings,
I have a rather interesting challenge ahead.
I need to build a control system that consists
of 2 PC's that have *fast* (not NFS) access to
each other's disk drives. I am considering putting
2 host adapters into each PC and then interconnecting
the HA's for disk access. My configuration would look
something like this:
SCSI BUS 1
PC1/HA2---->PC2/HA1---->PC2/SCSI_DISK
SCSI BUS 2
PC2/HA2---->PC1/HA1---->PC1/SCSI_DISK
Has anyone out there ever tried anything like
this using LINUX & PC hardware? I know it is
possible to put multiple HA's on a SCSI BUS 'cause
I've seen it done on a Motorola VME UNIX system
using their MVME327A.
I currently have redhat 4.2 and am using a single
adaptec AHA2940 with a SEAGATE ST52160N drive.
Thanks for any help
George Lass
