What is SAN Storage
A storage area network (SAN) is an exclusive network of storage devices that offers a shared storage pool to multiple computers and servers. Data storage in centralized shared storage architecture, such as SANs, enables organizations to manage storage from a single location and implement uniform policies for security, data protection, and disaster recovery.
What is the function of SAN?
SANs are used to give multiple computers and servers access to a shared storage pool. Direct-attached storage is how storage appears to networked computers.
A SAN transfers the storage responsibility from individual servers to a single location where it can be managed, protected, and accessed. Storage traffic performance is optimized when servers and workloads are not forced to share LAN bandwidth with traffic from storage devices.
How is SAN storage implemented?
The cabling, host bus adapters, and SAN switches connected to storage arrays and servers are SAN’s constituent parts. In order to connect servers to logical disk units (LUNs), a collection of block storage from a pool of shared storage, and make them appear to the server as a logical disk, SANs use block-based storage and high-speed architecture.
Host, fabric, and storage are the three separate layers that make up a SAN.
The host layer is made up of the SAN-connected servers that run business workloads that need access to storage, such as g. databases.
SAN hosts communicate with a server’s operating system using host bus adapters (HBAs), unique network adapters designed specifically for SAN access. This enables a workload to use the operating system to send storage commands and data to the SAN and its storage resources.
The network fabric that connects SAN hosts and storage is made up of cabling and networking hardware, which together make up the fabric layer. SAN switches, gateways, routers, and protocol bridges are examples of SAN networking devices.
By providing numerous alternate pathways from hosts to storage across the fabric, the fabric layer offers more redundancy than a typical network. As a result, the SAN is able to communicate using a different path if there is a disruption on one path.
Multiple storage devices, most commonly hard disk drives (HDDs), but also sometimes solid state drives (SSDs), CDs, DVDs, and tape drives, are included in the storage layer. RAID groups can be created from storage devices within a SAN to increase storage capacity and boost reliability.
Multiple protocols are supported by SAN technologies, enabling communication between operating systems, layers, and applications. The most frequently used protocol is the Fibre Channel Protocol (FCP), which is based on the Fibre Channel (FC) technology. Small and medium-sized businesses frequently use Internet Small Computing System Interface (iSCSI), a less expensive FC substitute.
Benefits of using SAN Storage
For enterprise workloads, SAN solutions have a number of advantages, such as:.
Enhanced data security
Data protection algorithms are implemented centrally with a SAN. This guarantees that all the servers in the SAN are configured with the same security and compliance settings.
A SAN’s centralized features can be used to manage all of the storage resources on the SAN, simplifying storage management. Data deduplication, storage replication, and data encryption are examples of features.
Storage in a SAN is accessible via a number of paths and continues to be independent of applications. The network fabric can use a different path to maintain storage availability if a communication failure occurs.
SANs can consist of thousands of SAN host servers and storage units, and they can be scaled out by adding new hosts and storage capacity to meet shifting business requirements.
Improvement in Performance
With a SAN, storage processing is transferred from servers to a separate network specifically for storage-related tasks. Traffic performance is unaffected by LAN traffic because the SAN is solely used for storage, so it is dedicated to that purpose. Due to the reduction of storage traffic and the resulting increase in bandwidth, SAN solutions also improve LAN performance.
