Embodiment Construction

[0014] The information storage equipment for network aggregation storage is composed of a host interface HI (Host Interface), a message exchange hub Th (Traffic-hub,) and m storage media parts MP (Medium Parts); the host interface HI and m storage parts MP serve as Network nodes are based on the message exchange hub Th, and follow a message transmission format called logical addressing structure LAS (Logical Addressing Structure) to exchange messages with each other, and use the file system logical unit address to define the name field of the logical addressing structure LAS; file system logic The unit address is a s-bit binary number i, s is a non-zero positive integer, i=0,1,...,2 s -1, the sth of the s-bit binary number i 0 bit, 00 1 and low address i 0 Two parts, high address i 1 As the network address of the storage medium part MP, the lower address i 0 is the logical unit address inside the storage medium part MP; each storage medium part MP internally deploys at leas...

Abstract

The invention relates to information storage technology, in particular to information storage equipment for network aggregation storage. Solve the problem that the sector granularity of the addressing unit of large-capacity storage equipment is too small, resulting in too long storage addresses. The information storage equipment of the network aggregation storage consists of a host interface HI, a message exchange hub Th and m Each storage medium component MP is composed; between each storage medium component MP, and between the MP and the host interface, the LAS message of the logical addressing structure is transmitted based on the message exchange hub Th, forming a storage medium network with the MP as the node; its network nodes The address and the storage unit address are aggregated into a whole, that is, the logical unit address of the file system. The invention effectively solves the management problem of the super-long address of the independent large-capacity storage equipment, can increase the speed while expanding the capacity, and is suitable for storage and access of supercomputers and large data.

Description

technical field [0001] The present invention relates to information storage technology, in particular to a storage system architecture where network addresses and storage addresses are aggregated, specifically information storage equipment for network aggregated storage. Background technique [0002] Independent information storage equipment specifically refers to a collection of storage media managed by a single file system, and expanding its storage capacity means increasing the granularity of the storage unit or extending the address length of the storage unit. So far, the physical addressing units of existing storage devices (mechanical hard disks, solid-state disks, SSDs, etc.) are all 512Byte sectors, and must follow a message transmission protocol based on sector addressing, FIS (Frame Information Structure, referred to as FIS protocol) and A host (Host) exchanges information, which is hereinafter referred to as a storage medium based on FIS access (FIS device for sho...
