Emerging of SANs

In a traditional enterprise information system, each data storage has to be bound to each server. As the amount of data to be handled by the syatem is doubling per year, the enterprise is increasingly suffering from the following problems.

  • High cost of data management
  • I/O performance bottleneck

A SAN is a high-speed network based on FC (fibre channel) which provides "any-to-any" connectivity between servers and storage. The SAN is highly expected to cut down TCO by storage consolidation and to improve system performance by high-speed data movement, such as data replication and backups, through FC.

Emerging of SANs

SAN Solutions Laboratory (SNSL) has been developing SAN solutions called "Storage Server" whose examples are listed below.

  1. Direct Backup
  2. Remote Copy
  3. Data Replication
  4. Integrated Storage Management
  5. Shared File System
  6. Storage Wide Area Network

Direct Backup

Moves data directly from disk drives to tape devices without consuming cpu power of servers and bandwidth of a LAN.

Direct Backup

High Speed Data Replication

Makes a copy of mainframe's data base which open systems can access for analytical applications such as data warehausing within a RAID.

High Speed Data Replication

Shared File System

Creates a computing environment where mainframes and open systems can directly read and write the same files.
