Test Cases 1: SSD Read Cache with 1 / 2 / 4 / 8 SSDs
This test verifies the dramatic performance gains offered by SSD read cache. We test the SSD read cache with 1 / 2 / 4 / 8 SSDs. According to the design structure of RAID level in SSD read cache pool, in theory, the more SSDs are used, the better SSD read cache is. We also set the populate-on-read threshold to 1 which means the data hits once and is populated to SSD.
