CPFS for Lingjun is a new, high-performance storage system from Alibaba Cloud designed specifically for AI workloads. It features a distributed parallel storage architecture, a proprietary RoCE RDMA network protocol, virtual storage channel technology, and a tiered cache elastic client. This architecture delivers high throughput, low latency, and serverless storage capabilities.
Why Choose CPFS for Lingjun
CPFS for Lingjun supports compute-intensive AI applications such as AIGC, autonomous driving, and large model training, which require ultra-high throughput and low I/O latency. Its core capabilities include the following:
High performance: A distributed parallel architecture enables a single file system to deliver up to 2 TB/s throughput and 30 million IOPS. When integrated with OSS, throughput reaches up to 100 GB/s.
Low latency: Consistent sub-millisecond I/O latency.
Scalability: Supports online scale-out, with performance scaling linearly as capacity increases.
Massive file support: A fully symmetrical metadata server architecture enables a single file system to manage up to 10 billion files and sustain over 100,000 metadata operations per second (OPS).
Cost efficiency: Optimized data flow with OSS reduces overall data storage costs.
Security: Supports log audit and data protection through Cloud Backup to ensure user data security.
