Compatibility ProtecTIER V3.1.8 works with TSSC code level 5.10.8 or higer. ProtecTIER V3.1.8 requires the use of ProtecTIER Manager V3.1.8 or higher. ProtecTIER Manager earlier than V3.1.8 is not compatible with ProtecTIER Server V3.1.8; communication between the two will fail. To log in to a V3.1.8 ProtecTIER server, you must install ProtecTIER Manager V3.1.8 or higher. Replication is supported from ProtecTIER V2.4 and later, but V2.1 SMB systems are also supported. Replication between ProtecTIER V2.3 and ProtecTIER V3.1.8 is not supported. Replication configuration operations require the use of Replication Manager V3.1.8 and later ProtecTIER software. ------------------------- OpenStorage compatibility - ProtecTIER Server v3.1.8 is compatible with plug-in 2.5.0.0 or later. - OpenStorage plug-in v3.1.8 is compatible with ProtecTIER Server v2.5 or later. -------------------- Compatibility matrix The compatibility matrix can be found at: http://www-03.ibm.com/systems/storage/tape/library.html#interoperability under the "TS7650/TS7650G ISV and interoperability matrix" heading. -------------------------------------------------------------------------------
