Distributed Storage

File object erasure coding

Storage capacity Up to 72PB

Aggregate bandwidth Up to 720GB/s

IOPS Up to 20 million IOPS

Product Overview

Scale-out storage for massive unstructured datasets

Distributed storage supports massive datasets, big data analytics, AI datasets, scientific computing, surveillance, satellite remote sensing and object storage.

Built on a new hardware platform and distributed architecture, all Jingcun cluster nodes process client I/O in parallel. Replication and N+M erasure coding provide data redundancy in a Scale-Out system designed for massive unstructured datasets.

Jingcun distributed storage pools resources and allocates them on demand, with expansion as workloads grow. Maximum capacity reaches 72PB, aggregate bandwidth reaches 720GB/s, and performance reaches 20 million IOPS. Different workloads can receive high-performance or low-cost high-capacity resources.

Simultaneous block, file and object services provide a unified resource pool for enterprise big data, file sharing, cloud computing, surveillance, research, AI, chip design and autonomous driving.

Key Features

Distributed Storage — Core Capabilities

Security and reliability

Strong replica consistency and drive- and node-level fault tolerance. Replication addresses demanding protection needs, while erasure coding balances reliability and space efficiency.

Unified multiprotocol services

Block, file and object storage, with NFS and CIFS/SMB through file gateways and standard S3 access through object gateways.

Massive scale-out expansion

Hash-based data placement removes dependence on traditional centralized controllers during reads and writes. Adding nodes increases both capacity and performance.

High-performance access

SSD caching, RDMA and DPDK address high-bandwidth, highly concurrent and large-scale data-access requirements.
