Hybrid Libraries

Hybrid library is the basic orientation of the present development library. Along with the fast growth of digitalized resources, it is extremely essential to set up a storage system which can meet the need of visiting mass storage and sharing backups. Based on the comparison of the main features of three storage systems (DAS, NAS and SAN) in terms of its notion of designing, connection protocol, style of management and its security, this paper focuses on the situation of the application of centralized management of data mainly constructed on the basis of SAN, tiered storage, as well as the storage system with good safety and strong extensibility in North China Institute of Science & Technology(NCIST).

Remote Sites

As microscope images are increasingly being created and stored digitally, researchers are in need of tools to help them organize and quickly search these collections. Because of the large amount of storage taken up by digital images they are frequently kept on bulk storage systems remote from the microscopist’s PC or workstation. The interface to these mass storage systems may be awkward and viewing large, remotely stored images can be very slow, making it difficult for the user to find a desired image.The LBNL Image Library was designed and implemented to provide a system to help researchers organize, browse and search through digital image collections, especially collections where the original images are stored off-line in a mass storage system. We also wanted to facilitate co-operative research by allowing access to the images by specified users at local and remote sites.

The wan Internet storage system based on Distributed Hash Table uses fully distributed data and metadata management, and constructs an extensible and efficient mass storage system for the application based on Internet. However, such systems work in highly dynamic environments, and the frequent entry and exit of nodes will lead to huge communication costs. Therefore, this paper proposes a new hierarchical metadata routing management mechanism based on DHT, which makes full use of the node stabilization point to reduce the maintenance overhead of the overlay. Analysis shows that the algorithm can effectively improve efficiency and enhance stability.

Backup And Recovery

IBM Spectrum Protect (ISP) software, one of the leader solutions in data protection, contributes to the data management infrastructure operated at CNAF, the central computing and storage facility of INFN (Istituto Nazionale di Fisica Nucleare – Italian National Institute for Nuclear Physics). It is used to manage about 55 Petabytes of scientific data produced by LHC (Large Hadron Collider at CERN) and other experiments in which INFN is involved, stored on tape resources as the highest latency storage tier within HSM (Hierarchical Space Management) environment. To accomplish this task, ISP works together with IBM Spectrum Scale (formerly GPFS - General Parallel File System) and GEMSS (Grid Enabled Mass Storage System), an in-house developed software layer that manages migration and recall queues. Moreover, we perform backup/archive operation of main IT services running at CNAF, such as mail servers, configurations, repositories, documents, logs, etc. In this paper we present the current configuration of the HSM infrastructure and the backup and recovery service, with particular attention to issues related to the increasing amount of scientific data to manage, expected for the next years.

Capacity Cost

Tape is an excellent choice for archival storage because of the capacity, cost per GB and long retention intervals, but its main drawback is the slow access time due to the nature of sequential medium. Modern enterprise tape drives now support Recommended Access Ordering (RAO), which is designed to reduce data recall/retrieval times. BNL SDCC's mass storage system currently holds more than 100 PB of data on tapes, managed by HPSS. Starting with HPSS version 7.5.1, a new feature called “Tape Order Recall (TOR) has been introduced. It supports both RAO and non-RAO drives. The file access performance can be increased by 30% to 60% over the random file access. Prior to HPSS 7.5.1, we have been using an in-house developed scheduling software, aka ERADAT. ERADAT accesses files based on the file logical position order. It has demonstrated a great performance over the past decade long usage in BNL. In this paper we will present a series of test results, compare TOR and ERADAT's performance under different configurations to show how effective TOR (RAO) and ERADAT perform and what is the best solution in data recall from SDCC's tape storage
