Will be very interesting to see how this affects SAP installations. AFAIK the only database options were SQL Server and Oracle. Granted it's been >5 years since I had to deal with this mess but this could be amazing news for some people on SAP who were pretty much forced to run Windows just for the database.
In fact, this is not the case.
Actually, besides ORACLE and MS SQL Server you can use also DB2 and other SAP's own DB products(MAXDB, Sybase, HANA).
I am talking about ERP and CRM, the main products.
Anyway, this is a very interesting news. Given the "not so good" relationship between SAP and Oracle, this option will give SQL Server a boost when it comes to SAP Customers, although it may take some time for SAP to fully support the Linux-MSSQL option.
SAP Business One is available with SQL server or HANNA. In fact resellers I have been talking to seem to have been instructed to sell HANNA first. I was told with the trade-off of more expensive hardware (HANNA) against more expensive licensing (SQL Server) it would come in about the same cost, but with the advantages of an in-memory database (especially when it comes to analytics) going to HANNA.
