Problem we are facing
 Scalability --Rapidly growing data volume
 Connectivity --Distributed data sharing
 24/7 availability, no single point failure
 High performance
 Easy management

Storage Trend and Demand
40G/100G SAN and LAN2010+

7. www.kerneltraining.com
Three Basic Forms of Network Storage
 Direct access storage (DAS)
 Network attached storage (NAS)
 Storage area network (SAN)
 And a number of variations on each (especially the
last two)

DAS Benefits
 Ideal for local data provisioning
 Quick deployment for small environments
 Simple to deploy
 Reliability
 Low capital expense
 Low complexity

Network-Attached Storage(NAS)

12. www.kerneltraining.com

13. www.kerneltraining.com
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
 Connection: homogeneous vs. heterogeneous

Storage Area Network (SAN)

15. www.kerneltraining.com
Storage Area Network (SAN)
 SAN is created by
using the Fibre Channel
to link peripheral
devices such as disk
storage and tape
libraries

16. www.kerneltraining.com
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.

21. www.kerneltraining.com
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. The limitations on the
number of attached devices typical of channel
interconnection disappears.

22. www.kerneltraining.com
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.

23. www.kerneltraining.com
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.

24. www.kerneltraining.com
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

25. www.kerneltraining.com
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.
