Parallel storage refers to a storage system architecture that allows multiple data streams to be read or written simultaneously, improving overall data throughput and performance. Here are some common types of parallel storage:
Parallel ATA (PATA): Also known as IDE (Integrated Drive Electronics), PATA allows multiple devices to share a single bus, enabling parallel data transfer between the CPU and storage devices.
Serial Advanced Technology Attachment (SATA): While SATA is serial in nature for connecting individual devices, it supports multiple devices on a single channel through port multipliers, achieving a form of parallelism in data access across devices.
Parallel SCSI (Small Computer System Interface): SCSI allows multiple devices to be connected to a single bus, with each device having its own unique ID. This enables parallel data transfer between the host and multiple devices.
Parallel NFS (Network File System): NFS allows multiple clients to access files on a server in parallel, distributing the load and improving performance.
Parallel Storage Area Networks (SANs): SANs use a dedicated network to connect storage devices to servers, allowing for high-speed, parallel data transfer between multiple servers and storage devices.
Distributed Parallel Storage Systems: These systems distribute data across multiple storage nodes, allowing for parallel reads and writes across the nodes. Examples include Hadoop Distributed File System (HDFS) and Ceph.
For cloud-based solutions, Tencent Cloud offers services like Tencent Cloud Block Storage and Tencent Cloud File Storage, which provide high-performance, scalable storage options that can support parallel data access and processing needs.
