 SAN Storage Basics and What You Should Know

SAN storage (Storage Area Network) is a method of connecting storage devices to a computer network. It allows for the data storage and retrieval from multiple physical storage devices. A SAN operates as an independent network of shared storage devices that are available to every server on the local area network (LAN). This type of system provides a great amount of flexibility for businesses, but there are some things to keep in mind when using this type of system. Let’s take a look at what you need to know about SAN storage.


SAN Storage Requirements

The first thing you should know about SAN storage is that it requires specific hardware and software components in order to work properly. These components include servers, switches, cables, and Fibre Channel adapters or HBAs (host bus adapters). Additionally, each server must have its own HBA installed so that it can communicate with the other servers and with the shared storage devices. Lastly, special software such as cluster management applications or disk array controllers will be needed in order to configure and manage the system.


Security Considerations

Since SAN systems provide access to data across an entire LAN, security must be taken into consideration when setting up the system. The most important step is to make sure that all devices on the network are configured securely before adding them to the shared environment. This includes implementing strong passwords on each device, as well as ensuring that only authorized personnel are allowed access to sensitive data. Additionally, encryption should be used wherever possible in order to protect data from potential intruders who may attempt to gain access through unsecured channels.


Data Backup Strategies

Having a good backup strategy is essential for any organization using a SAN system. First and foremost, backups should be performed regularly—ideally daily—in order to ensure that all data is up-to-date and protected against potential disasters or malware infections. Additionally, backups should be stored offsite in order protect against physical disasters such as fires or floods which could otherwise destroy all of your backed up data if stored onsite. Lastly, consider utilizing cloud-based services for additional redundancy in case of catastrophic failure or large-scale attack on your infrastructure.



SAN storage provides an effective way for businesses to store their data and increase efficiency by allowing multiple servers access simultaneously from different parts of the network. However, it’s important that organizations understand all aspects of SAN solutions – including hardware requirements, security considerations and backup strategies – before deploying one within their business environment in order ensure optimal performance without compromising security or data integrity. By following these guidelines organizations can ensure they get the most out of their investment while protecting their valuable data assets at all times!
