Unlike the scalability design of a cache server cluster, the scalability of the data storage server cluster demands higher data durability and availability.The purpose of the cache is to speed up the data read and reduce the load pressure on the data storage server.Therefore, the loss of some cached data does not affec

1. SectionA section (extent) is a basic storage unit used to allocate space for tables and indexes. It consists of 8 contiguous 64KB data pages.The main points of the concept of allocating space based on segments rather than actual use of space: Once the section is full, the space that the next record will occupy is not the size of the record, but the size of the whole new zone. Assign one segment at a time instead of assigning a record.

The two concepts are similar, but belong to different technologies. Server virtualization and Storage virtualization technologies are designed to separate physical systems from specific workloads in order to simplify the environment by consolidating and quickly allocating resources. Server virtualization solutions typically encapsulate operating systems and appli
