Added the open-source BeeGFS deployment guide. |
BeeGFS is both a network file system and a parallel file system, complying with the POSIX standard. The client communicates with the storage server via network. BeeGFS supports the native verbs interface and TCP/IP-based connection or connection via RDMA-capable networks like InfiniBand (IB), RDMA over Converged Ethernet (RoCE), and Omni-Path (OPA). By increasing the number of servers in the system, BeeGFS aggregates their capacity and performance in a single namespace. |
|
2 |
Added the open-source FastDFS deployment guide. |
FastDFS is an open-source high-performance distributed file system (DFS). It provides functions including file storage, file synchronization, file access, high capacity, and load balancing. It is mainly used to store massive data and is especially suitable for online services based on small- and medium-sized files (recommended range: 4 KB < file_size < 500 MB). |
|
3 |
Added the open-source MinIO deployment guide. |
MinIO is a lightweight unstructured distributed file storage service. It is compatible with Amazon S3 cloud storage service interfaces and is suitable for storing large-capacity unstructured data, such as images, videos, log files, backup data, and container/VM images. An object file can be of any size, ranging from several KB to 5 TB. |
|
4 |
Added the open-source Lustre deployment guide. |
Lustre is a cluster-oriented storage architecture. It is an open-source cluster (parallel) file system based on the Linux platform and provides file system interfaces compatible with POSIX. Lustre features high scalability and high performance. It supports tens of thousands of client systems, PB-scale storage capacity, and hundreds of GB aggregated I/O throughput. |

Added the new feature "data compaction." |
The data compaction algorithm of Kunpeng BoostKit for SDS is deployed on the open-source distributed storage cluster Ceph to eliminate data waste caused by zero padding. In addition, combined with functions including data encapsulation, space allocation based on block counting, granularity-based traffic diversion, batch submission, and batch callback, the data compaction algorithm improves the data reduction ratio and overall system IOPS, which reduces costs and improves performance. |
|
2 |
Added the new feature "global cache." |
Kunpeng BoostKit for SDS provides a global cache, which is a distributed cache system deployed on an open-source Ceph storage cluster for I/O acceleration. Global Cache improves IOPS performance of distributed storage systems and shortens access delays without increasing hardware costs. |
