Why SAN & application is important?

  • Importance of the subject for CSE students:

This subject helps students to know how the data can be stored in server side. How to take backup and managing.

  • What is this subject pre-requisite for ? (if applicable)

Computer Network and OS is needed to under the SAN Technology

  • Few real-world applications examples:

Distributed clients and servers are frequently chosen different OS and Software and genearte huge amount of data. how it can effectively managed.

  • RAID
  • Virulaisation
  • Backup Techniques
  • Scope of the subject from Job / Higher studies:

Students can apply for jobs if he wants to develop a career in server side and managing the different Data center.

Introduction to SAN

  • What is SAN ?
  • A storage area network (SAN) is a dedicated high-speed network or sub network that interconnects by using FC technology

History

11 of 42

Problem we are facing

  • Scalability --Rapidly growing data volume
  • Connectivity --Distributed data sharing
  • 24/7 availability, no single point failure
  • High performance
  • Easy management

​

12 of 42

Importance of SAN�

  • Centralized management
  • Support for sharing removable-media libraries
  • Heterogeneous platform support
  • Remote vaulting and mirroring
  • Real-time backup

THE ROLE OF SAN IN AN ORGANIZATION

​

  • To revise data protection and security.
  • SAN in an organization is akin to the heart in the body.
  • SAN is used to enhance the availability of applications if you have multiple data paths.
  • To remediate the performance of the application, if you face off-load storage functions.

Server-Attached Storage (SAS)

17 of 42

SAS -- How to Share Data

  • Each has own copy
    • scalability: Poor
    • availability: OK
    • performance: OK
    • management: how to keep data sync?
    • Connectivity: NA
  • One copy, share
    • single point failure
    • not that good
    • how to make back up without affecting service?
    • System dependent

​

Network-Attached Storage(NAS)

19 of 42

NAS

  • Scalability: good
  • Availability: as long as the LAN and NAS device work, generally good
  • Performance: limited by speed of LAN, traffic conflicts, inefficient protocol
  • Management: OK

Storage Area Network (SAN)

21 of 42

Storage Area Network (SAN)

  • SAN is created by using the Fibre Channel to link peripheral devices such as disk storage and tape libraries

22 of 42

SAN vs. NAS

  • Dedicated Fibre Channel Network for Storage
  • More efficient protocol
  • ==> higher availability
  • ==> reduce traffic conflict
  • ==> longer distance (up to 10 km)

​

​

Fibre Channel

  • provides high-performance, any-to-any interconnection.
    • server to server
    • server to storage
    • storage to storage
  • combines the characteristics of networks (large address space, scalability) and I/O channels (high speed, low latency, hardware error detection) together.

24 of 42

Benefits of SAN

  • Scalability ==> Fibre Channel networks allow the number of attached nodes to increase without loss of performance because as switches are added, switching capacity grows.

25 of 42

Benefits of SAN

  • High Performance ==> Fibre Channel fabrics provide a switched 100Mbytes/second full duplex interconnect.
  • Storage Management ==> SAN-attached storage allows the entire investment in storage to be managed in a uniform way.

26 of 42

Benefits of SAN

  • Decoupling Servers and Storage
    • the servers can be upgraded while leaving storage in place.
    • Storage can be added at will and dynamically allocated to servers without downtime.

27 of 42

Easy Migration to SAN

  • Host Bus Adapters (HBAs) -- connect servers to the SAN
  • Fibre Channel storage -- connects directly to the SAN
  • SCSI-FC bridge -- allows SCSI (disk and tape) components to be attached to the SAN
  • SAN Network Components -- Fibre Channel switches

28 of 42

Summary

  • SAN is a high-speed network that allows the establishment of direct connection between storage devices and processors (servers) centralized to the extent supported by the distance of Fibre Channel.
