A storage area network (SAN) is configured to connect storage devices, servers, and switches to support multiple users.
Companies use a SAN to provide the same pool of shared storage devices to multiple servers and access points.
See below for all about the global SAN market:
The SAN market had an estimate worth $17.82 billion in 2019. With an expected compound annual growth rate (CAGR) of 3.5% between 2020 and 2027, it is expected to reach $23.47 billion by the end of the period.

SAN systems have great potential to scale and accommodate many storage devices and grant access to many users. A SAN can be deployed in two ways, depending on the type of networking technology used.
iSCSI stands for Internet Small Computer Systems Interface. It is an Internet block protocol used to create storage networks over an Ethernet connection. An iSCSI SAN solution routes traffic over a shared or dedicated network for storage.
Using iSCSI SAN improves storage utilization and manageability by reducing overall operating costs. It also does not require specialized upfront hardware and can be deployed using the same equipment as a local area network (LAN).
Fiber Channel SAN
Fiber Channel SANs are deployed on top of fiber networks, creating a connection between storage points and devices across the entire network using routers, gateways, and switches.
The use of fiber for SAN solutions is generally more specialized, but it provides high network speeds between all endpoints in a network. It is ideal for high traffic, high access storage areas.
SANs work primarily by removing storage from individual servers and facilitating access and centralized management and protection of stored data. All storage devices are connected via an external network to centralized servers.
Advantages of SAN
Using SAN to manage storage with a large network of devices offers a range of benefits that make it the go-to option for many businesses.
- Advanced management features
- High scalability
- High-end security capabilities
- Fast data transfer
- Optimized for disaster recovery
- Easy data duplication
- Dynamic storage tiering
“SANs have traditionally used the SCSI over FC protocol. Future SANs will use the emerging low-overhead NVMoeF (NVMe extended to run on fabrics) protocol over Ethernet,” said Jai Menonmember of the Forbes Technology Council.
“Plus, SAN arrays are built as software on standard x86 servers, and there’s no price premium.”
SAN use cases
Here are several examples of how SAN is used by organizations in different industries to solve data storage problems.
Shibuya is an IT service provider for business infrastructure in Sweden. A member of the Pulsen Group, Shibuya provides customized IT solutions in the Nordic region.
Seeking to grow as a business with data-intensive applications, including artificial intelligence (AI), big data, and analytics, Shibuya needed a cost-effective solution for its IT infrastructure. The deployment of IBM Storage Networking SAN46B-6 enabled it to meet the demands of its customers.
“With IBM’s flexible and cost-effective technology, we can deliver cloud environments that precisely match our customers’ business priorities,” says Christian Wibeckbusiness development manager in Shibuya.
“In our industry, saying we’re using IBM technology opens doors and gets people’s attention, which helps us grow our market share.”
Keelings is a multinational fresh produce supplier based in Ireland, with 2,400 employees and operations in 42 countries. Its primary focus is growing, sourcing, shipping, marketing and selling fresh produce and product-specific enterprise resource planning (ERP) software.
When it began to outgrow its old SAN system, Keelings turned to Pure Storage to help improve its storage performance and perform maintenance work on its spinning disk systems.
Pure Storage’s Evergreen storage business model allowed Keelings to deploy its storage once and upgrade it as needed over time. Keelings has secured proactive support alongside its onsite IT staff and is able to upgrade storage without disrupting business operations.
“The Pure Evergreen storage model was a huge selling point. With Pure Storage, you take storage to the next level, meeting the business demands that many businesses will have today and in the future,” says Dave ClarkeAssistant Group IT Manager at Keelings.
“Pure Storage support was very good. The interface is very usable, with everything labeled and well thought out.
University of Würzburg
The University of Würzburg is a public research institution in Germany. Founded in 1402, the university has 28,000 students studying a wide variety of subjects, in addition to 4,000 researchers and faculty members.
With an IT team of 50 professionals, the university needed to install a flexible and scalable storage and server infrastructure to store and access its student and research data.
Together with Hewlett Packard Enterprise (HPE), the University of Würzburg has integrated a complete solution of storage devices, servers and fiber channels for its network components, including its StoreFabric SAN architecture. This is a long-term solution that has allowed the university to have enough buffer memory in its SAN and tape libraries for years to come.
“With both HPE 3PAR StoreServ 7400 and HPE StoreEver ESL G3 Tape Libraries with LTO-6 tapes, we now have a large enough buffer to handle the growing data volumes our installations will generate over the next few years. years “, says Matthias ReichlingDeputy Data Center Director and Director of Central and Decentralized Services, University of Würzburg.
“We have always had excellent experiences with HPE hardware and fantastic service from partner Bechtle.”
