Title: METHOD FOR ACCESSING SHINGLED MAGNETIC RECORDING (SMR) HARD DISK, AND SERVER
Abstract:
A method for accessing a shingled magnetic recording (SMR) hard disk, and a server, for solving the technical problem of the low efficiency of a server accessing an SMR hard disk. The method comprises: a server receiving a data operation request, wherein the data operation request comprises address information about target data (S101); the server determining, according to the address information, a target storage zone corresponding to the target data on an SMR hard disk (S102); the server determining that write pointer information about the target storage zone exists in a cache, and acquiring the write pointer information from the cache, wherein the write pointer information is address information about the latest stored data in the target storage zone (S103); the server generating, according to the write pointer information and the address information about the target data, a data operation instruction, wherein the data operation instruction is used for operating the target data (S104); and the server sending the data operation instruction to the SMR disk (S105).
