One of the bottlenecks of distributed file systems deals with mechanical hard drives (HDD). Although solid-state drives (SSD) have been around since the 1990's, HDDs are still dominant due to large capacity and relatively low cost. Hybrid hard drives with a small built-in SSD cache does not meet the need of a large variety of workloads. This paper proposes a ...

Most of large-scale distributed file systems decouple metadata operation from reading or writing operation for a file. In other words, certain servers named metadata server (MDS) is responsible for maintaining the metadata information of file systems. But, mostly the existing file systems are used are strictive metadata management technique, because those systems mostly designed to focus a distributed management of ...

In such file systems, nodes simultaneously serve computing and storage functions, a file is partitioned into a number of chunks allocated in distinct nodes so that MapReduce tasks can be performed in parallel over the nodes.

Need of storing huge amounts of data has grown over the past years. The data should be stored for future reuse or for sharing among users. Data files can be stored on a local file system or on a distributed file system. A distributed file system provides many advantages such as reliability, scalability, security, etc. This paper shows new trends in these systems with a focus on increasing performance. These include the organization of data and metadata storage, usage of caching, and design of replication algorithms.
One of the bottlenecks of distributed file systems deals with mechanical hard drives (HDD). Although solid-state drives (SSD) have been around since the 1990's, HDDs are still dominant due to large capacity and relatively low cost. Hybrid hard drives with a small built-in SSD cache does not meet the need of a large variety of workloads. This paper proposes a middleware that manages the underlying heterogeneous storage devices in order to allow distributed file systems to leverage the SSD performance while leveraging the capacity of HDD. We design and implement a user-level file system, HyCache, that can offer SSD- like performance at a cost similar to a HDD. We show how HyCache can be used to improve performance in distributed file systems, such as the Hadoop HDFS. Experiments show that HyCache achieves up to 7X higher throughput and 76X higher IOPS than Linux Ext4 file system, and can accelerate HDFS by 28% at 32-node scales (compared to vanilla HDFS).
Most of large-scale distributed file systems decouple metadata operation from reading or writing operation for a file. In other words, certain servers named metadata server (MDS) is responsible for maintaining the metadata information of file systems. But, mostly the existing file systems are used are strictive metadata management technique, because those systems mostly designed to focus a distributed management of data and an input/output performance rather than the metadata. In this paper, we present a new non-shared metadata management technique in order to provide flexible metadata throughput and scalability. First, we introduce a new metadata distribution technique called dictionary partitions (DP). Then, we introduce load distribution technique based DP. In addition, we demonstrate the superiority of our technique with shared metadata management technique.
Distributed file systems (DFS) are key building blocks for cloud computing applications based on the MapReduce programming paradigm. In such file systems, nodes simultaneously serve computing and storage functions, a file is partitioned into a number of chunks allocated in distinct nodes so that MapReduce tasks can be performed in parallel over the nodes. However, in a cloud computing environment, failure is the norm, and nodes may be upgraded, replaced, and added in the system. Files can also be dynamically created, deleted, and appended. This results in load imbalance, that is, the file chunks are not distributed as uniformly as possible in the nodes. Although distributed load balancing algorithms exist in the literature to deal with the load imbalance problem, emerging DFSs in production systems strongly depend on a central node for chunk reallocation. This dependence is clearly inadequate in a large-scale, failure-prone environment because the central load balancer is put under considerable workload that is linearly scaled with the system size, and may thus become the performance bottleneck and the single point of failure. In this paper, we illustrate and define the load rebalancing problem in cloud DFSs. We advocate file systems in clouds shall incorporate decentralized load rebalancing algorithms to eliminate the performance bottleneck and the single point of failure. Simulation results for a potential distributed load balancing algorithm are illustrated. The performance of our proposal implemented in the Hadoop distributed file system is also demonstrated.
We present the development of a tool for analyzing the interactions between parallel/distributed file systems and databases in a Linux cluster environment. We begin with an overview of existing file system and database technology. We then discuss the actual design of the tool. A sample set of results on a small Linux cluster using NFS and Postgres are presented and analyzed by way of a demonstration and discussion of how this utility may be used for performance assessment
A large class of modern distributed file systems treat metadata services as an independent system component, separately from data servers. The availability of the metadata service is key to the availability of the overall system. Given the high rates of failures observed in large-scale data centers, distributed file systems usually incorporate high-availability (HA) features. A typical approach in the development of distributed file systems is to design and develop metadata services from the ground up, at significant cost in terms of complexity and time, often leading to functional shortcomings. Our motivation in this paper was to improve on this state of things by defining a general-purpose architecture for HA metadata services (which we call RMS) that can be easily incorporated and reused in new or existing file systems, reducing development time. Taking two prominent distributed file systems as case studies, PVFS and HDFS, we developed RMS variants that improve on functional shortcomings of the original HA solutions, while being easy to build and test. Our extensive evaluation of the RMS variant of HDFS shows that it does not incur an overall performance or availability penalty compared to the original implementation.
With the development of cloud computing, the distributed file systems are getting more and more attention. In this paper, we introduce the concept and the features of the distributed file system, and analyse several popular systems, such as Hadoop, Moosefs and Lustre. Especially, the tested performance comparison of these systems is given. Finally, we propose the research trends in the future.
Previous distributed file systems have relied either on convention or on obtaining dynamic global agreement to provide network transparent file naming. The authors argue that neither approach can succeed as systems scale to the kind of size that is anticipated in the current decade. They propose instead a novel name-mapping scheme which relies on a fragmented, selectively replicated name translation database. Updates to the naming database are coordinated by an optimistic concurrency control strategy with automatic propagation and reconciliation. A prototype of the name-mapping mechanism has been implemented and is in use in the Ficus replicated file system.<<ETX>>
Recently, the analysis of small files is required to provide individual users with the latest information and optimized services. In this paper, we propose a distributed cache management scheme that considers cache metadata for efficient accesses of small files in Hadoop Distributed File Systems (HDFS). The proposed scheme can reduce the number of metadata managed by a Name Node since many small files are merged and stored in a chunk. It also reduces unnecessary accesses by keeping the requested files using clients and the caches of data nodes and by synchronizing the metadata in client caches according to communication cycles.
We propose a mechanism for improving the performance of name resolution operations in distributed file systems. The mechanism is based on the idea of reducing the number of message exchanges required for the resolution of a particular file name. In this mechanism, users are given the flexibility to dynamically define and change their performance requirements for the various file names being used by them.<<ETX>>
