MySQL Product Models
UDB MySQL Cloud Database offers NVMe model and SSD Cloud Disk model. Regardless of the model, the reliability, persistence, and read-write performance of UDB-MySQL will fulfill the product SLA commitment.
NVMe model database instances adopt the mainstream computing storage separation architecture in the industry: the computing layer uses high-performance SurferCloud Kuaijie cloud hosts, and the storage layer adopts ultra-high-performance RDMA NVMe SSD cloud disks. RSSD cloud disks are based on the new generation of distributed block storage architecture, with NVMe SSD as the storage medium at the bottom layer, and RDMA for network transmission, providing users with the highest random read and write capabilities of up to 1.2 million per disk and even lower single-path latency capabilities. The relationship between IOPS and capacity: when the disk size is below 1T, IOPS is optimized to a fixed value of 50000, and when it is above 1T, IOPS is calculated according to a fixed allocation algorithm, the calculation formula is: 1800 + 50 * size(GB), with a maximum IOPS of 1.2 million. The disk step size is 10GB, it supports large-capacity storage, and the maximum capacity can reach 32T.
Database instances of SSD cloud disk model are generally deployed in available areas where NVMe models are not provided. The computing storage separation architecture is adopted, with SSD cloud disks used for bottom layer storage.
MySQL Cloud Database provides a high-availability dual-master hot standby architecture, supports the construction of high availability across available areas, and supports the construction of slave libraries across available areas to achieve disaster recovery at the available area level, ensuring high service availability.
