Division principles of OceanStor 9000's tiers: - If you do not add new tier CONFIGUREs, all node pools are of the default tier. - A hotspot data storage tier is created for the data that is frequently accessed. All nodes that have high data processing capabilities and fast response speeds are located in this tier for accelerated response speed and improved storage performance. - A common data storage tier is created for the data that is less-frequently accessed. All nodes that have moderate response speeds but can provide large storage space are located in this tier for reduced deployment and maintenance costs. - It is recommended that node pools in the same tier be of the same type. However, you can adjust the type of node pools in a tier as required.

Division principles of OceanStor 9000's pool nodes
Division principles of OceanStor 9000's pool nodes: - All nodes in a node pool must be of the same type. - In V100R001C01 and V100R001C20, a node pool contains 3 to 20 nodes. - In V100R001C30, if a node pool consists of P12, P25, P36, or C36 nodes, the node pool can contain 3 to 20 nodes. If a node pool consists of C72 nodes, the node pool can contain 2 to 10 nodes. - After deployment, nodes in a node pool cannot be modified. - If you want to modify a node, you must delete the node from its original pool first, and then add the node to a new pool.
