SAN Storage

Data Centre Storage

SAN storage, the backbone of modern-day data centres. As businesses continue to rely on technology for daily operations, the need for secure and efficient data storage solutions has become increasingly important. In this article, we’ll take a deep dive into what SANs are, different types, and pros and cons. We’ll also explore the future of SAN in light of emerging technologies like cloud computing and artificial intelligence.

SAN storage

SAN storage provides a reliable way to protect data using data storage by creating a dedicated network solely for storage traffic. A SAN can have many different types of data storage connected and you can create a Fibre Channel SAN, iSCSI/IP SAN or SAS SAN, from this you can connect different types of storage including disk and tape. Normally a SAN will have multiple levels of redundancy built-in to enable the storage and servers to access block data across the network in the event of failure.

What is SAN Storage?

SAN stands for Storage Area Network, and it refers to a high-speed network that enables storage devices to communicate with servers. In simpler terms a SAN is a dedicated network of shared storage devices that provides block-level access to data.

SANs are designed to enable multiple servers to access the same pool of storage resources simultaneously. This makes them an ideal solution for large-scale enterprise environments where multiple users need reliable and fast access to stored data.

One key advantage of SANs over other types of storage networks is their ability to provide centralized management and control over the entire storage infrastructure. With SANs, administrators can easily allocate, distribute and manage large volumes of data across different servers without requiring physical reconfiguration or manual intervention.

Another benefit of SANs is their scalability. As businesses grow and demand more extensive data centres, they can scale up their SAN infrastructures by adding more switches, hosts or disk arrays as needed.

SAN technology offers several advantages in terms of speed, reliability, flexibility and scalability compared with other types of storage technologies.

The Different Types of SAN Storage

There are a few different types of SAN that are commonly used in data centres.
One type is Fibre Channel (FC), which uses a high-speed network to connect servers and storage devices. FC SANs can support very large amounts of data, making them ideal for enterprises with big data needs.

Another type is iSCSI, which is similar to FC but uses Ethernet connections instead of fibre optic cables. This makes it more affordable and easier to implement than FC SANs.

Network Attached Storage (NAS) is another type of SAN that allows multiple users or applications to access the same files or data simultaneously over a network. NAS systems typically use file-level protocols such as NFS or SMB.

There are also software-defined storage solutions that provide virtualized pools of storage across physical hardware components. These can be easily scaled up or down depending on business needs.

Each type has its own pros and cons depending on factors like cost, scalability, performance requirements, and ease-of-use. Ultimately, choosing the right type comes down to understanding your specific business needs and goals.

Storage considerations

Whilst a SAN provides a high level of performance and can simplify storage management, things start to get complicated the more storage systems are added to the storage area network when you have multiple servers connecting to many different storage pools. SAN storage provides for better disk space usage as the disk can be carved up to provide space to multiple servers and applications, also many storage systems also provide thin provisioning, snapshot, replication and many other features. Wherever possible ensure your storage has redundant controllers, multiple NIC ports and supports SSD.

What is the Future of SAN Storage?

The future of storage is looking bright as more businesses are recognising the need for scalable and secure data centres. With the rise of big data, cloud computing, and virtualization technologies, traditional storage solutions are increasingly becoming inadequate to meet modern business demands.

One trend that’s likely to shape the future of storage is software-defined networking (SDN). SDN allows administrators to configure their networks through a central management console rather than manually configuring individual switches or routers. This makes it easier to manage complex storage environments with multiple arrays and hosts.

Another trend that’s set to transform SANs is hyper-converged infrastructure (HCI), which combines compute, network, and storage resources into a single unified system. HCI can simplify deployment, reduce costs and improve performance while also making it easier to scale up or down as needed.

As technology continues to evolve at an exponential rate, so too will the capabilities of storage systems. Advancements such as solid-state drives (SSDs), artificial intelligence (AI) and machine learning algorithms will continue pushing towards faster speeds with higher accuracy rates whilst widening scalability options for any type(s) of workload required by businesses in various industries.

The future looks promising for those investing in SAN Storage solutions. As long as there are new technological advancements out there waiting be adopted by companies worldwide; these types of investments may prove useful now more than ever before!


Current fibre channel speeds run at 64Gb/s, most deployed FC networks are 8-32Gb/s. An IP or iSCSI SAN has traditionally run at 10GbE, but network cards and switches are now making 25-100GbE more affordable to deploy and will eventually replace fibre channel due to the reduced cost, greater performance and less complexity from trying to manage two networks.

SAN Products

We provide a host of SAN products that can be a robotic tape library, all-flash array, hybrid array with flash and hard disk or a traditional disk array supporting the latest 25TB drives and SSD drives. The storage systems can be supplied with multiple controllers cards to support either iSCSI or Fibre Channel and fully support active-active failover and VMware VAAI.


A SAN is a crucial component of any efficient data centre. It offers high performance and scalability while also providing centralised management for multiple servers.

While it’s difficult to predict the future of technology, one thing is certain – data centres will continue to grow in size and complexity. To keep up with this growth, storage systems will need to become even more scalable and flexible.

By understanding the pros and cons of different types of storage solutions and staying up-to-date on emerging technologies in this field, organisations can make informed decisions about how best to leverage these powerful tools for their business needs.
