Erasure Code Configuration The default erasure parity configuration is as follows: Erasure Set Size Default Parity (EC:M) 1 EC:0 2-3 EC:1 4-5 EC:2 6 - 7 EC:3 8 - 16 EC:4 The maximum parity is ERASURE_SET_SIZE/2, meaning the number of parity blocks cannot exceed the number of data blocks.微信公众号MinIOStorageOperationsPerformanceTestingBenchmarkingPerformance Testinghttps://www.chenshaowen.com/en/blog/multi-node-multi-disk-minio-cluster-performance-test-in-different-erasure-code-configurations-on-ipoib.htmlSun, 08 Feb 2026 00:00:00 +0000Sun, 08 Feb 2026 00:00:00 +0000https://www.chenshaowen.com/en/blog/multi-node-multi-disk-minio-cluster-performance-test-in-different-erasure-code-configurations-on-ipoib.htmlThe earlier tests found the bottleneck in the NIC; this post adds supplementary testing under IPoIB. 1.

Installing Dependencies MindCluster ToolBox is a system-level toolset for cluster operations and hardware management, mainly used for operations such as device monitoring, performance testing, and log collection. MindCluster ToolBox includes the Ascend DMI tool, the log collection tool, and the Ascend Cert tool. MindCluster ToolBox works by calling low-level DCMI (Device Control Management Interface) and AscendCL (Ascend Computing Language) interfaces to perform the relevant detection functions; system-level information queries are implemented by calling the general-purpose libraries provided by the system.微信公众号AIDMIAscendHuaweiNPUTroubleshootingPerformance Testinghttps://www.chenshaowen.com/en/blog/3fs-performance-test.htmlTue, 11 Mar 2025 00:00:00 +0000Tue, 11 Mar 2025 00:00:00 +0000https://www.chenshaowen.com/en/blog/3fs-performance-test.html1.

Environment Preparation Enter a safe directory 1 mkdir -p /data/test && cd /data/test All the test tasks are carried out in this directory. Create a separate directory for Redis 1 mkdir redis-data It is recommended to create a new directory, because Redis will change the Owner of the files in the current directory to systemd-coredump.微信公众号JuiceFSDragonflyStoragePerformance TestingKubernetesOperations
