FPGA-accelerated compactions for LSM-based key-value store 20

FPGA-accelerated compactions for LSM-based key-value store

Log-Structured Merge Tree (LSM-tree) key-value (KV) stores have been widely deployed in the industry due to its high write efficiency and low costs as a tiered storage. To maintain such advantages, LSM-tree relies on a background compaction operation to merge data records or collect garbages for housekeeping purposes. In this work, we identify that slow compactions jeopardize the system performance due to unchecked oversized levels in the LSM-tree, and resource contentions for the CPU and the I/O. We further find that the rising I/O capabilities of the latest disk storage have pushed compactions to be bounded by CPUs when merging short KVs. this causes both query/transaction processing and background compactions to compete for the bottlenecked CPU resources extensively in an LSM-tree KV *** this paper, we propose to offload compactions to FPGAs aiming at accelerating compactions and reducing the CPU bottleneck for storing short KVs. Evaluations have shown that the proposed FPGA-offloading approach accelerates compactions by 2 to 5 times, improves the system throughput by up to 23%, and increases the energy efficiency (number of transactions per watt) by up to 31.7%, compared with the fine-tuned CPU-only baseline. Without loss of generality, we implement our proposal in X-Engine, a latest LSM-tree storage engine.

Rapid growth in data storage technologies created the modern data-driven world. Modern workloads and application have influenced the evolution of storage devices from simple block devices to more intelligent object devices. Emerging, next-generation Key-Value (KV) storage devices allow storage and retrieval of variable-length user data directly onto the devices and can be addressed by user-desired variable-length keys. Traditional reliability schemes for multiple block storage devices, such as Redundant Array of Independent Disks (RAID), have been around for a long time and used by most systems with multiple ***, the question arises as to what an equivalent for such emerging object devices would look like, and how it would compare against the traditional mechanism. In this paper, we present Key-Value Multi-Device (KVMD), a hybrid data reliability manager that employs a variety of reliability techniques with different trade-offs, for key-value devices. We present three reliability techniques suitable for variable length values, and evaluate the hybrid data reliability mechanism employing these techniques using KV SSDs from Samsung. Our evaluation shows that, compared to Linux mdadm-based RAID throughput degradation for block devices, data reliability for KV devices can be achieved at a comparable or lower throughput degradation. In addition, the KV API enables much quicker rebuild and recovery of failed devices, and also allows for both hybrid reliability configuration set automatically based on, say, value sizes, and custom per-object reliability configuration for user data.

Data placement is critical for the scalability of decentralized object-based storage systems. the state-of-the-art CRUSH placement method is a decentralized algorithm that deterministically places object replicas onto storage devices without relying on a central directory. While enjoying the benefits of decentralization such as high scalability, robustness, and performance, CRUSH-based storage systems suffer from uncontrolled data migration when expanding the clusters, which will cause significant performance degradation when the expansion is *** paper presents MAPX, a novel extension to CRUSH that uses an extra time-dimension mapping (from object creation times to cluster expansion times) for controlled data migration in cluster expansions. Each expansion is viewed as a new layer of the CRUSH map represented by a virtual node beneath the CRUSH root. MAPX controls the mapping from objects onto layers by manipulating the timestamps of the intermediate placement groups (PGs). MAPX is applicable to a large variety of object-based storage scenarios where object timestamps can be maintained as higher-level metadata. For example, we apply MAPX to Ceph-RBD by extending the RBD metadata structure to maintain and retrieve approximate object creation times at the granularity of expansions layers. Experimental results show that the MAPX-based migration-free system outperforms the CRUSH-based system (which is busy in migrating objects after expansions) by up to 4.25× in the tail latency.

Consistent and timely access to an arbitrarily damaged file system is an important requirement of enterprise-class systems. Repairing file system inconsistencies is accomplished most simply when file system access is limited to the repair tool. Checking and repairing a file system while it is open for general access present unique challenges. In this paper, we explore these challenges, present our online repair tool for the NetApp (R) WAFL (R) file system, and show how it achieves the same results as offline repair even while client access is enabled. We present some implementation details and evaluate its performance. To the best of our knowledge, this publication is the first to describe a fully functional online repair tool.

Consensus protocols can provide highly reliable and available distributed services. In these protocols, log entries are completely replicated to all servers. this complete-entry replication causes high storage and network costs, which harms *** coding is a common technique to reduce storage and network costs while keeping the same fault tolerance ability. If the complete-entry replication in consensus protocols can be replaced with an erasure coding replication, storage and network costs can be greatly reduced. RS-Paxos is the first consensus protocol to support erasure-coded data, but it has much poorer availability compared to commonly used consensus protocols, like Paxos and Raft. We point out RS-Paxos's liveness problem and try to solve it. Based on Raft, we present a new protocol, CRaft. Providing two different replication methods, CRaft can use erasure coding to save storage and network costs like RS-Paxos, while it also keeps the same liveness as *** demonstrate the benefits of our protocols, we built a key-value store based on CRaft, and evaluated it. In our experiments, CRaft could save 66% of storage, reach a 250% improvement on write throughput and reduce 60.8% of write latency compared to original Raft.

We present DevFS, a direct-access file system embedded completely within a storage device. DevFS provides direct, concurrent access without compromising file system integrity, crash consistency, and security. A novel reverse-caching mechanism enables the usage of host memory for inactive objects, thus reducing memory load upon the device. Evaluation of an emulated DevFS prototype shows more than 2x higher I/O throughput with direct access and up to a 5x reduction in device RAM utilization.

A standard feature of enterprise data storage systems is synchronous replication: updates received from clients by one storage system are replicated to a remote storage system and are only acknowledged to clients after having been stored persistently on both storage systems. Traditionally these replication schemes require configuration on a coarse granularity, e.g. on a LUN, filesystem volume, or whole-system basis. In contrast to this, we present a new architecture which operates on a fine granularity-individual files and directories. To implement this, we use a combination of novel per-file capabilities and existing techniques to solve the following problems: tracking parallel writes in flight on independent storage systems;replicating arbitrary filesystem operations;efficiently resynchronizing after a disconnect;and verifying the integrity of replicated data between two storage systems.

Spiffy: Enabling file-System Aware storage Applications 16

Spiffy: Enabling File-System Aware Storage Applications

Many file-system applications such as defragmentation tools, file system checkers or data recovery tools, operate at the storage layer. Today, developers of these storage applications require detailed knowledge of the filesystem format, which takes a significant amount of time to learn, often by trial and error, due to insufficient documentation or specification of the format. Furthermore, these applications perform ad-hoc processing of the filesystem metadata, leading to bugs and vulnerabilities. We propose Spiffy, an annotation language for specifying the on-disk format of a file system. file-system developers annotate the data structures of a file system, and we use these annotations to generate a library that allows identifying, parsing and traversing file-system metadata, providing support for both offline and online storage applications. this approach simplifies the development of storage applications that work across different file systems because it reduces the amount of file-system specific code that needs to be written. We have written annotations for the Linux Ext4, Btrfs and F2FS file systems, and developed several applications for these file systems, including a type-specific metadata corruptor, a file system converter, and an online storage layer cache that preferentially caches files for certain users. Our experiments show that applications that use the library to access file system metadata can achieve good performance and are robust against file system corruption errors.

the performance and lifespan of a solid-state drive (SSD) depend not only on the current input workload but also on its internal media fragmentation formed over time, as stale data are spread over a wide range of physical space in an SSD. the recently proposed streams gives a means for the host system to control how data are placed on the physical media (abstracted by a stream) and effectively reduce the media fragmentation. this work proposes FStream, a file system approach to taking advantage of this facility. FStream extracts streams at the file system level and avoids complex application level data mapping to streams. Experimental results show that FStream enhances the filebench performance by 5%similar to 35% and reduces WAF (Write Amplification Factor) by 7%similar to 46%. For a NoSQL database benchmark, performance is improved by up to 38% and WAF is reduced by up to 81%.

We introduce protocol-aware recovery (PAR), a new approach that exploits protocol-specific knowledge to correctly recover from storage faults in distributed systems. We demonstrate the efficacy of PAR through the design and implementation of corruption-tolerant replication (CTRL), a PAR mechanism specific to replicated state machine (RSM) systems. We experimentally show that the CTRL versions of two systems, LogCabin and ZooKeeper, safely recover from storage faults and provide high availability, while the unmodified versions can lose data or become unavailable. We also show that the CTRL versions have little performance overhead.
