Sainsbury?s has installed a 32-processor Intel server based on Numa technology to analyse up to three terabytes of data collected on its loyalty card database.
The supermarket chain already runs a Data General 16-processor Aviion 20000 Numa server to run an Oracle database on which its loyalty card data is stored. Now the store has decided to add a second server running 32 Pentium Pro 200Mhz processors linked to the data warehouse over a high-speed network connection to enable all this data to be analysed.
?Sainsbury?s is investing in technology that will allow the company to get closer to its customers. Data General?s ccNuma server has proven to be a flexible platform, allowing us to adapt and extend our data warehouse to three terabytes in the near future,? said Martin Wright, infrastructure manager at Sainsburys.
Wright said tests conducted between themselves and Data General showed scalability across the eight internal nodes of four processors averaged 92 per cent.
More than 300 business users will interrogate the loyalty card data warehouse, which is connected from one of Sainsbury?s two data centres to the stores wide area asynchronous transfer mode network.
Using software tools such as Brann Viper and Information Advantage, results of interrogations will be used for merchandising planning and campaigns.
Numa is an extension of symmetric multiprocessing technology, enabling a large number of processors to share an application and memory, reducing latency with large amounts of cache memory. Aviion 20000 ccNuma servers running 32 processors retail upwards of #500,000.
