The strategy would be to purchase CHARON VAX systems on HP servers with sufficient horsepower to replace your existing VAX systems. There would then be an HP SAN drive with 15,000 RPM drives containing the data from the CI cluster on it which would be shared amongst the multiple CHARON VAX servers via a Fibrechannel link. The lock manager NI clustering traffic between the CHARON VAX servers would be over the 100 MB Ethernet link that would be dedicated NICs on the CHARON VAX servers. Then there would be additional NICs on the CHARON VAX servers as needed for user connection or other connections. If you had Alphas off of the CI cluster the Alphas could share data with the VAX either through MSCP serving of the data from the SAN to the CHARON VAX systems for drive sharing or the CHARON VAX can MSCP share the drives to the Alpha systems. In either case the CI cluster goes away and it becomes a SAN wit NI clustering.
