Description
DDN's web object scaler (WOS) offers an alternative approach to managing large scale distributed data. WOS is designed without the overheads associated with traditional filesystems that normally underpin higher-level distributed middleware system. File system checks, fragmentation, RAID sets and inode structures have been removed in WOS and a simple, efficient placement of objects directly to disk is instead implemented. The approach moves metadata management to external software/middleware, which fits well with most current large scale distributed data systems. We present some alternative implementations of WOS in real-world environments and discuss performance of WOS for several use-cases.
