SAN Storage

Benefits Of SAN Storage , Storage Array Network And Attached Storage With Difference Between SAN And NAS

SAN technology addresses advanced enterprise storage demands by providing a separate, dedicated, highly scalable high-performance network designed to interconnect a multitude of servers to an array of storage devices.
 
The storage can then be organized and managed as cohesive pools or tiers.
 
A SAN enables an organization to treat storage as a single collective resource that can also be centrally replicated and protected, while additional technologies, such as data deduplication and RAID, can optimize storage capacity and vastly improve storage resilience compared to traditional direct attached storage (DAS)
 
 
 

SAN Storage Introduction

 

A Storage Area Network (SAN) is a high-speed network that provides multiple servers access to consolidated pools of shared, block-level storage.

 
 
 

Who uses SAN Storage?

 

Organizations of all sizes use Storage Area Networks (SANs) to increase storage utilization rates (i.e. multiple hosts accessing the storage devices), improve application performance and availability, and to heighten security and data protection capabilities.

By presenting storage devices to hosts such that they appear to be locally attached storage, SANs also facilitate the presentation of storage to users

Why should I consider SAN Storage?

 

SANs work by providing block level, high-speed network access to storage for multiple hosts.

By interconnecting hosts, switches, controllers and storage, and using a variety of high speed, high reliability communications protocols, SANs can consolidate previous “islands” of storage.

 

Benefits of SAN Storage

 

Benefits Of SAN Storage is deliver highly reliable, highly scalable block level storage solutions, accessible by many hosts.

Increased storage utilization rates often drive down storage cost of ownership, while multiple security and reliability features ensure mission critical data is always protected and available.

These enterprise-class features make SANs the storage solution of choice for today’s data driven organizations.

Network Attached Storage Data Storage

 

The Difference Between SAN And NAS  SAN vs. NAS

 

Both SAN and network attached storage NAS are methods of managing storage centrally and sharing that storage with multiple hosts (servers).

However, NAS is Ethernet-based, while SAN can use Ethernet and Fibre Channel.

In addition, while SAN focuses on high performance and low latency, Network Attached Storage NAS focuses on ease of use, manageability, scalability, and lower total cost of ownership (TCO).

Unlike SAN, NAS storage controllers partition the storage and then own the file system.

Effectively this makes a NAS server look like a Windows or UNIX/Linux server to the server consuming the storage.

 

SANs are often used to :

 

  • Improve application availability (e.g., multiple data paths)
  • Enhance application performance (e.g., off-load storage functions, segregate networks, etc.)
  • Increase storage utilization and effectiveness (e.g., consolidate storage resources, provide tiered storage, etc.), and improve data protection and security.
  • SANs also typically play an important role in an organization’s Business Continuity Management (BCM) activities.

 

SANs are commonly based on Fibre Channel (FC) technology that utilizes the Fibre Channel Protocol (FCP) for open systems and proprietary variants for mainframes.
 
In addition, the use of Fibre Channel over Ethernet (FCoE) makes it possible to move FC traffic across existing high speed Ethernet infrastructures and converge storage and IP protocols onto a single cable.
 
Other technologies like Internet Small Computing System Interface (iSCSI), commonly used in small and medium sized organizations as a less expensive alternative to FC, and InfiniBand, commonly used in high performance computing environments, can also be used.
 
In addition, it is possible to use gateways to move data between different SAN technologies.
