The NeoSapphire 3706 is equipped with two HA nodes, each configured with an identical SSD group. Every disk group is composed of 12 SSDs, with one used as a spare. The logs/tables are saved across the other 11 SSDs in the group, with one used for storing parities. For single-node NeoSapphire models, the logs/tables are saved in the same way across all the SSDs, apart from one spare.
