San mass Storage Solution

San mass Storage Solution

With the advent of Fibre Channel technology and the development of network technology, the enterprise's deep understanding of centralized storage has gradually formed the concept of storage network. The storage network can realize data security storage management, realize data sharing between different platforms, and can provide users with 24x7 data access. Storage networks are mainly NAS (network-attached storage) and SAN (storage area Network). The common point of the two is to storage devices as the center, can realize the sharing of storage devices, centralized storage for easy management. The difference lies in the two kinds of storage networks, such as network connection, data access control and so on. Different storage networks can be selected according to different application environments.

SAN (Storage Area Network) Introduction

A storage Area network (Storage zone Network--san) is a storage network system based on a storage protocol that enables the server to communicate with the storage device for "Any to no" connections.

Because of the limitations of SCSI technology in terms of bandwidth, security, and connectivity flexibility, a new channel technology has been developed?? Fibre Channel technology, with the advantage of Fibre Channel technology, can achieve the previously impossible or difficult to implement the application model. Fibre Channel technology is widely used not only because Fibre Channel has higher bandwidth, longer connection distances, better security, and scalability, but Fibre Channel technology is a good blend of channel technology and network technology, using Fibre Channel to create a storage area network San that is different from the previous LAN.

A SAN enables interconnection between any server in the corporate information system, any array subsystem, and any tape system. Using a SAN can build a storage pool, realize multiple servers sharing an array subsystem, share an automatic band library, realize data sharing and centralized management.

the advantages of a SAN storage network :

Good Scalability

Sans use Fibre Channel technology. In fc-loop form, each fiber loop can support 126 optical devices. In the form of FC-SW (optical fiber exchange), optical networks can theoretically connect 16 million optical fiber devices. In other words, fiber optic network can be added to the optical devices to meet the expansion of the system needs.

far away from the transmission

Using multimode fiber transmission distance of up to 500 meters, using single-mode fiber transmission distance of up to 10 kilometers.

High transmission rate

The 200mb/s loop bandwidth of a SAN improves the storage bandwidth of the host system, which reduces the communication bandwidth between the server and the client because of the large amount of data that exists in the high speed SAN storage pool. Access to large amounts of data can be done through Sans.

High Backup efficiency

Lan-free data backup means that the data to be backed up is transmitted to the tape library through the San 100mb/s rate, with only a small amount of control information transmitted over the TCP/IP network. Significant savings in TCP/IP network bandwidth resources.

Flexible Configuration

The corresponding software can realize the network file sharing based on San, and the file access efficiency is high.

Good security

Access control for switch ports can be achieved through the zooning function of the fiber switch. Secure isolation at the LUN level through the Seastor disk array lun masking. File share access control is realized through software.

When the data is in a regular state of access, the data is stored in the SII 1000 fibre disk array system and can be accessed directly by the data server or client host, and when the data is not accessed for a longer period of time (for example, 30 days), Third-party tiered storage software scans data files stored on SII 1000 according to pre-set rules and policies. The data files that qualify for migration are then migrated to the SII f500a disk array, which is managed by the tiered storage software, while only one file pointer remains on SII 1000 , a user or application can still access a data file that has been migrated through a file pointer, except that when the file is accessed, the file data is automatically redeployed from the SII f500a disk array in the background to SII 1000, a process that is transparent to users and applications. Thus, it realizes the automatic management function of data hierarchical storage.
