Test Case 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 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 the SSD.
