Performance Test: StorPool “SSD-Hybrid” shared storage system with 20x SSDs and 40x HDDs

Boyan Ivanov Blog Leave a Comment

This is a test of a StorPool Distributed Storage system, which we call “SSD-Hybrid”. It consists of 20 SSDs and 40 HDDs, spread evenly across 5 storage servers (nodes). The system uses 3 copies of each piece of data in a different server to guarantee redundancy (i.e. 3x replication). All reads and writes come/go the the SSDs first and are …
