A storage area network (SAN) is a dedicated network that provides access to consolidated, block-level data storage. A SAN consists of storage devices, high-speed connectivity components, and SAN management software. It connects servers to storage infrastructure, facilitating high-speed data transfer between servers and storage through three methods: server-to-server, server-to-storage, and storage-to-storage. SANs use various interconnect technologies and topologies like point-to-point, arbitrated loop, and switched fabric. SAN management oversees the organization, configuration, monitoring, and troubleshooting of SAN components to enable secure and robust data transfer.
A storage area network (SAN) provides centralized storage for multiple servers to access over a network. SANs are useful for large networks that require more storage than a single server can offer, allowing terabytes of data to be accessible by multiple machines. The key components of a SAN include fiber channel switches that connect servers and storage devices, host bus adapters that interface storage with operating systems, and storage devices like fiber channel disks. SANs provide benefits like high storage capacity, reduced costs, increased performance, and improved backup and recovery compared to adding more individual servers. However, SANs also have disadvantages in being expensive to implement and maintain and requiring technical expertise.

The document discusses different types of storage networks including direct attached storage (DAS), network attached storage (NAS), storage area networks (SANs) using Fibre Channel (FC) or iSCSI, and Fibre Channel over Ethernet (FCoE). DAS connects storage directly to servers but has limitations. NAS uses a traditional LAN to share storage files between servers but has performance limitations. SANs allow block-level access to centralized storage using high-speed FC networks or iSCSI over Ethernet. FCoE encapsulates FC frames in Ethernet to converge network traffic.
A Storage Area Network (SAN) provides block-level access to shared storage pools through high-speed fiber connections, allowing multiple servers to access storage. A SAN consists of hosts, logical unit numbers (LUNs), host bus adapters (HBAs), storage controllers, and multipathing input/output (MPIO). iSCSI allows SCSI commands to be transmitted over IP networks as an alternative to fiber channel, consisting of iSCSI qualified names (IQNs), software initiators, and extended unique identifiers (EUIs).
Network attached storage (NAS) allows centralized storage and sharing of data over a network. A NAS device maintains one or more hard disks and is directly connected to a network to provide file-level access to stored data. NAS provides benefits like simplified management, improved efficiency, and flexibility in accessing data globally compared to traditional localized storage. It uses common protocols like TCP/IP, NFS, and SMB to connect to client systems and retrieve or store data.

An enterprise private network is a computer network controlled by a single organization that connects multiple offices and locations. It allows resources like student information, teacher information, and finance systems to be securely shared across locations. Enterprise private networks first emerged in the 1970s and were built over telecom networks, but now often use virtual private network technology and encryption over public internet infrastructure. For example, one organization describes its use of a Layer 2 MPLS network with hub and spoke topology to connect various campuses and departments.
This document defines storage area networks (SANs) and discusses their architecture, technologies, management, security and benefits. A SAN consists of storage devices connected via a dedicated network that allows servers to access storage independently. Fibre Channel is the most widely used technology but iSCSI and FCIP allow block storage over IP networks. Effective SAN management requires coordination across storage, network and system levels. Security measures like authentication, authorization and encryption help protect data in this shared storage environment.

software drivers that enable HBAs to
communicate with the fabric layer.
This is the middle layer of a SAN, the network
part of a SAN, where hubs and switches tie all
the cables together into a logical and physical
network.
This is where all the data resides on
the disk drives
4. Components of SAN
Fibre Channel SAN environments and components enable the development of solutions that provide high performance and high
availability, which are the fundamental requirements of a storage network.
Fibre Channel devices effectively combat the problems related to bandwidth, which generally occur during bulky operations, such as
backup and restore operations. Hardware components offer different features to provide for a small SAN to a high-speed and high-
volume SAN data center.
A wide range of hardware and software products make up the components of a SAN. SAN components include:
Hubs
•Serve as the access point for the clients
•The hubs on a storage network are used to implement the ring-like Fibre Channel Arbitrated Loop
•Provide load balancing and data caching to improve performance

5. Interface Technologies
Fibre Channel can be considered the Ethernet of SANs and is the standard that all
major vendors support.
FCP - mapping of SCSI over FC It has been around for more than 10 years and is used in major corporations
worldwide. If you want a mature technology with wide support, Fibre Channel is an
excellent option.
iSCSI - mapping of SCSI over TCP/IP (Emerging Technology
& Comparatively slow )
InfiniBand A new contender in the SAN arena is Internet small computer system
interface (iSCSI), an IP-based standard for linking storage devices over a
network. The iSCSI protocol runs on top of a high-speed LAN infrastructure
as another Transmission Control Protocol/Internet Protocol (TCP/IP)
application, so you can use your existing network for a SAN without having
One of the newest SAN networking technologies is InfiniBand, which offers support from

major manufacturers but is still fairly new. Unlike the Peripheral Component Interconnect
(PCI) bus used with other networking technologies, InfiniBand can carry multiple
channels of data at the same time to improve throughput. With a low-overhead protocol
and high-speed throughput, InfiniBand could overtake Fibre
Channel in the future.
6. SAN Topologies
A topology is a physical layout diagram showing how network devices are
connected with each other.
The Basic SAN topologies are:
Point-to-point — A dedicated and direct connection exists between two SAN devices.
Arbitrated loop — The SAN devices are connected in the form of a ring.
Switched fabric — SAN devices are connected using a direct connection between fabric switch
In the point-to-point topology, there is a fabric switch. The the devices.

7. The Signs of a SAN
In summary, a SAN is a combination of hardware devices, interconnect
strategy, and concept. Even as the capabilities of the hardware and
speed of the interconnect change, the concept will remain stable.
A collection of servers, mass storage, interconnect devices, and
interconnection media constitutes a Storage Area Network, if it exhibits
most of the following
characteristics:
Storage is behind the server
Storage devices are connected to each other
Multiple servers are connected to the storage pool
Heterogeneous servers may be connected to the storage pool
Fibre Channel connectivity (fiber optic cable and FC host bus adapters)is
used
Fibre Channel hubs and switches are present
Multiple paths to devices exist
8. Benefits of SAN
SAN benefits provide high return on investment (ROI) and reduce the total cost of ownership (TCO) by increasing
performance, manageability, and scalability.
However, SANs are not for everyone. Sometimes the benefits do not justify the costs for small companies. A good
guideline is the use of 16 servers. If you have more than 16 servers, a SAN should be beneficial.
Some key benefits of SANs are:
Reduced data center rack and floor space — Because you do not need to buy big servers with room for many disks, you
can buy fewer, smaller servers, which takes less room in the data center.
Disaster recovery capabilities — SAN devices can mirror the data on the disk to another location.
Increased I/O performance — SANs operate faster than internal drives or devices attached to a LAN.
Fibre Channel SANs offers these additional benefits
Performance — Distance and speed
Efficiency — Reliability and nondisruptive scalability
Manageability — More devices supported with less people
Connectivity — Any-to-any connections
Cost effectiveness — Serverless backups and tape library sharing
Modular scalability — Dynamic capacity
Consolidated storage — Sharing of centralized storage
