  • Discover some workarounds for NLS challenges
Key Concept
Near Line Storage (NLS) using Sybase IQ allows data to be offloaded from the SAP BW HANA system and therefore saves on expensive HANA hardware and maintenance costs. However, there are several important things to understand about implementing this product before proceeding.

Near Line Storage (NLS) using Sybase IQ allows data to be offloaded from the SAP BW running on HANA system onto the NLS system. Sybase IQ is the database optimized for BI and NLS that is run by Sybase, a company purchased by SAP in 2010. Sybase IQ provides slower query access but does allow data that is not often used to be moved to the NLS system, thus freeing up the HANA system for newer, more dynamic data.

By offloading the data onto the NLS system, it is possible to still have access to this data for query purposes but it takes the data out of the costly HANA nodes which stores data hot in memory. This move typically results in big cost savings for companies. As the NLS tool using Sybase IQ is rather new, there are some important tips to understand how to optimize its use. Here I discuss what you need to consider when administering and implementing SAP NLS based on Sybase IQ.
