IBM Scientists Give Storage Some 'panache'
IBM's Almaden Research Center is developing several advanced technologies for storage and data analysis. Panache is a clustered file system that provides applications with high-speed access to a large pool of data even if the applications are far away. "Customers are asking us to give them a way, when data is created at one site, to make it available in other geographically distributed locations, so that users at those locations can access the data as if it were local," says IBM researcher Bruce Hillsberg.
Panache has a high level of parallelism, which allows multiple nodes to read and write to their local data cache while they are offline. "Panache is the first file system cache to exploit parallelism in every aspect of its design—parallel applications can access and update the cache from multiple nodes while data and metadata is pulled into and pushed out of the cache in parallel," according to the researchers.
Another new technology, Sage, calculates the value of data over time and moves it to the appropriate level of storage based on its value. Sage aims to help companies get data onto the right storage tier more quickly and reduce storage costs.
