Yahoo! “Unstructured Storage for the Internet” MObStor

Yahoo seems to prepare its storage cloud solution with a mouth-full name “Unstructured Storage for the Internet” or MObStor.  The storage solution will be used as the repository of various media contents and it will allow user to build on top additional services. The core storage will be highly secured and optimized for high performance.

Here is more from the Yahoo Developer Network Blog, they use Facebook’s Haystack to contrast MObStore.

“Facebook’s Haystack is based on commodity storage. While MObStor does support commodity storage, it doesn’t require it. Instead, we have a storage-layer abstraction we call the ObjectStore. The ObjectStore encapsulates the key storage operations we need to perform, and allows us to have many underlying physical object stores. This allows us to mix, for example, filer-based storage with commodity storage. The upper layers have the routing intelligence that determines which ObjectStore a given piece of data is stored in. However, like Haystack, we do support high request rates using our own optimized ObjectStore written to run on commodity hardware – with one important difference. While Haystack identifies every object using a 64-bit photo key, all objects in MObStor are accessible through logical (i.e., client-supplied) URLs, not object IDs.”
