The upcoming appliances have some technical advantages over other in-memory products, such as Tibco Spotfire and Microsoft PowerPivot, Evelson added. "Most of the other in-memory technologies are positioned as data marts or analytical sandboxes ... mostly because the size of the data you can load is limited to a single memory space. I haven't seen an in-memory model/data mart from these vendors larger than a few hundred GB."
Meanwhile, SAP's appliance "can have a number of blades and a single data model can span multiple memory spaces. They've tested it with models of 2TB and plan to go to as much as 4TB," he said.
Meanwhile, along with SAP's claimed advanced data compression capabilities, customers could conceivably push enterprise data warehouse-sized amounts of information into memory, Evelson added.
SAP is also planning to create a front end that allows many BI (business intelligence) tools to use it, compared to other platforms which support only their own proprietary front-ends, he said.
