What devices are included in a network storage system?

What are the components of a storage system?

Storage System Knowledge

Storage system consists of hardware system (disk arrays, controllers, disk cabinets, tape libraries, etc.), storage software (backup software; management software, snapshots, replication, and other value-added software), storage network (HBA cards, fiber optic switches, FC/SAS cables, etc.), and storage solutions (centralized storage, archiving, backup, disaster recovery, etc.).

Storage devices include what

Storage devices include memory, hard disk, floppy disk, magnetic tape, magnetic core memory, CD, DVD, MO and other devices.

1, the use of electrical energy way to store information devices such as: various types of memory, such as RAM, ROM and so on.

2. Devices that use magnetic energy to store information such as: hard disk, floppy disk (which has been phased out), magnetic tape, magnetic core memory, magnetic bubble memory (Magnetic bubble memory appeared in the 1970s but failed to achieve commercial success in the 1980s when the price of hard disks dropped dramatically.) , and USB flash drives.

3. Devices that utilize optical means to store information such as CDs or DVDs.

4. Devices that utilize magneto-optical means to store information such as MO (Magnetic Optical Disk).

5, devices that store information using other physical objects such as paper cards, paper tapes, etc. e.g.: punched cards, punched tapes, knots, etc.

6, dedicated storage system: for data backup or disaster recovery dedicated information system, the use of high-speed network for large data volume storage information equipment.

Stored procedures for storage devices

Stored procedures are written by the flow control and SQL statements, this process is compiled and optimized to be stored in the database server, the application program to use as long as the call can be. In ORACLE, several linked procedures can be combined to form a program package.

Stored procedures are programs written in the Transact-SQL language provided by SQLServer, which is the language provided by SQLServer for designing database applications, and is the primary programmatic interface between applications and the SQLServer database. It is the primary programmatic interface between applications and the SQLServer database. It is analogous to PL-SQL in the Oracle database system and the Informix-4GL language in the Informix database system architecture.

The computer’s storage system usually includes

The computer’s storage system usually includes:

I. Memory: is an important part of the computer.

It can be divided into:

Computer internal memory (referred to as memory)

Computer external memory (referred to as external memory)

Memory can be divided functionally into: read-write memory RAM, read-only memory ROM two major categories

Computer storage capacity in bytes as a unit, they are: byte B (1 Byte), kilobytes (1 Byte), kilobytes (1 Byte), kilobytes (1 Byte) and kilobytes (1 Byte). = 8bit), kilobytes (1KB = 1024B), megabytes (1MB = 1024KB), gigabytes (1GB = 1024MB), 1TB = 1024GB

Two, the computer’s external memory in general: floppy disks and floppy drives, hard drives, CD-ROMs, CD-ROMs, erasable CD-RW drives. RW drive and USB interface removable hard disk, CD-ROM, or rewritable electronic hard disk (flash drive) and so on.

The basic unit of memory capacity is the byte (Byte), and has the following arithmetic conversion relationship:





1 Chinese character needs 2 bytes to be stored in a computer;

1 Chinese character needs 2 bytes to be stored in a computer;

2 bytes to be stored in a computer. bytes to store;

1 English character (i.e., ASCII code) requires 1 byte to store in a computer;

1 byte is equivalent to 8 binary bits.

Extended information:

The storage system of a computer refers to the system in a computer that consists of a variety of storage devices that hold programs and data, control components, and devices and algorithms that manage the scheduling of information. The storage system is one of the important components of a computer. The storage system provides the ability to write and read out the information (program and data) needed for the computer to work, realizing the information memory function of the computer. Modern computer systems often use registers, cache, main memory, external memory multi-level storage architecture.

The core of the computer storage system is memory, memory is essential to the computer, used to store programs and data memory devices. Internal memory (referred to as memory) mainly stores the program and data needed for the current work of the computer, including cache memory (Cache, referred to as cache) and main memory.
