Abstract-In order to meet the challenges of significant storage and application growth, as well as shortened backup windows and limited IT resources, more and more organizations embrace Hierarchical Storage Management (HSM). Parts of SAN file systems provide the ability to support HSM, but they didn't provide more details in design considerations and how to implement. In this paper, we present design...
Efficient metadata management is critical in large scale cluster file systems. Based on service separation idea, a novel metadata management architecture is presented in this paper to improve metadata access performance and scalability. Storage management is completely separated from namespace and data services. A storage management server cluster singly deals with storage management. To further reduce...
Absorbing the slab idea for memory management, this paper presents a novel technique for the disk storage management called a storage slab allocator. A storage slab allocator doesnpsilat discard the file layout during the process of deleting files, but reuses the free file layout while creating, thereby both block allocation and release will be speeded up. The file layout is the cached-object as the...
This paper presents a flexible two-layer buffer caching scheme to improve the performance of storage cache which is used to serve multiple concurrently accessing applications with diverse access patterns. To achieve this, the proposed scheme dynamically partitions the cache among applications. At the first layer, it uses a configurable global cache allocation policy to make adaptive cache allocations...
In this paper we analyze aggregate workload characteristics of multiple I/O streams in shared storage environment such as storage area network (SAN). In these shared storage environments, independent and separate user data spaces make the access streams interleaved and localized. To evaluate overall storage performance or optimize data layout, it is important to understand aggregate workload characteristics...
