Question & Answer


Question

What application traffic is supported using SMC-R with RoCE?

Answer

"With the exception of IPSec traffic, all other TCP/IP traffic that could flow between QDIO OSA adapter ports on two z/OS V2R1 partners and that is found to be RDMA-eligible during the initial TCP setup, can exploit the RDMA connection.

Connection level security such as SSL or AT-SSL can be used with SMC-R.

Examples include – but are not limited to -- WAS type 4 connections, Cognos (z/OS) to DB2 connectivity that goes cross-LPAR, CICS to CICS via IPIC, WebSphere MQ, etc. Sysplex Distributor traffic is also supported.

If the connection is usable it will be used and there is no required change needed for applications." (Linda Harrison, SMC-R RoCE FAQ Document, http://www-03.ibm.com/support/techdocs/atsmastr.nsf/WebIndex/FQ131485)
