This presentation discusses one customer’s approach to replacing ICB4 links with HCA2-O Infiniband in a single sysplex environment consisting of 8 CPCs that were being migrated from 2097s to z196s. Infiniband provides opportunities with both performance and consolidation. The HCA3 offering is also discussed along with performance benefits associated with upgrading from the HCA2-O to the new HCA3-O  cards. The HCA3 performance data is based on experiences working on the Infiniband Redbook, the GA2 ESP of the HCA3 fanout cards and a conversion to the HCA3 cards in production. George Handera, Aetna Inc.
