SAP INFO: Powerful Corporate Memory: Data management using nearline storage
Nearline storage systems are a type of midway house between a relational online database and an offline archive. The data stored in these systems can be called up very quickly without impacting on the database. A special type of data storage compresses the storage volume, allowing queries to be processed more quickly and cut costs.
SAP INFO: Dieting for Databases: ENTEGA Service uses nearline solution from SAND to store SAP data
By Roland Markowski
ENTEGA Service is channeling its growing data volumes in SAP NetWeaver Business Intelligence with a nearline storage solution from SAND Technology. The german company uses the solution to store all data that is not immediately required, but which still needs to be accessible for audit purposes. As a result, the database stays lean while storage costs and run times for queries and backups are reduced.
The Next Generation of Enterprise Data Warehousing
By Jürgen Haupt, SAP AG, Regional Implementation Group (RIG), EMEA and Dr. Michael Hahne, SAND Technology
Recent technological developments have made it possible to overcome – or in the cases where the data explosion has not yet “hit”, to proactively avoid – the challenges described above. Specifically, SAND Technology, an SAP® Software Partner, has successfully integrated SAND/DNA 2.3 with SAP NetWeaver BI as a nearline storage component. The SAP Certified Integration of SAND/DNA enables customers using SAP NetWeaver BI to implement an efficient nearline repository that can keep massive volumes of less frequently used data (as held in DataStore Objects in the Data Acquisition layer and the Data Propagation layer of the EDW) in a tiny footprint, in a format that permits rapid, easy access. Based on practical experience in the production environments of several customers using SAND/DNA with SAP NetWeaver BI (both with SAP Business Information Warehouse Release 3.1/3.5 and with SAP NetWeaver BI 7.0), it is realistic to expect between 85% and 95% compression, depending on InfoObject type, data volume and data diversity.
Near-Line Storage Keeps Static Data Available - SAP NetWeaver Magazine
By Michael Hahne
Near-line components allow the data warehouse to scale cost-effectively to hold many TB — even petabytes (PB) — of accessible data. However, near-line data storage doesn’t necessarily replace archival storage. For one thing, it may not qualify as a compliance-certified “point of record” creation for original data (see “Meeting Compliance Regulations” below). In some cases, the data stored in near-line storage is not in its original form, but is a representation or transformation of the original data. You still need archival, certified storage to keep the originals and to guarantee the retention of old data that you’re unlikely to ever require for reporting or analysis again. In these cases, it’s appropriate — and may be less expensive — to use archival storage instead of near-line storage.
Techworld.com - Ninety percent data compression at VW - and it’s not de-dupe
The ability of SAND/DNA to compress selected data to an extremely high degree (approximately 90 percent on average) while making it available for use in reporting or as the basis for new DataStore objects or InfoCubes was the key factor in Volkswagen Financial Services’ decision. The low total cost of ownership, due to the need for far less administrative support as compared with standard archiving solutions, was also very appealing.

By Michael Hahne
The IT service provider RI Solution GmbH has achieved a compression rate of 96 percent for its data in SAP NetWeaver Business Intelligence. Thanks to nearline storage, the company is saving on archiving costs and at the same time has lower administration expense. In addition, users can access InfoCubes and PSA objects without any loss in performance.

InfoWorld | SAND/DNA Digs Into Compressed Data
Sand Technology this week updated its DNA Dynamic Nearline Architecture data management technology, which compresses data to about 10 percent of its original size and allows the stored data to be searched without being decompressed. Sand is integrating its Sand/DNA Analytics analytic data repository with its SAND/DNA Access storage archival product, and adding new features to both offerings. The integration allows end-users to pull information transparently from SAND/DNA Access and load it into SAND/DNA Analytics using standard business intelligence tools. This removes much of the time spent on data modeling, according to SAND officials. Sand also introduced SAND/DNA for SAP Business Warehouse, which allows users to move, store, and access highly compressed data from a nearline data repository.
