The important feature on the front end that is provided to the clients by multiple servers that access the same storage devices across the SAN (Storage Area Network) is redundancy.
Redundancy is a key feature of SANs that provides high availability and fault tolerance for storage resources. In a SAN environment, multiple servers can access the same storage devices simultaneously, which allows for load balancing and fault tolerance. This means that if one server fails, the other servers can continue to access the storage devices without interruption, ensuring that the storage resources are always available to the clients.
Redundancy is typically achieved through the use of redundant components, such as redundant storage devices, power supplies, and network connections. These redundant components are designed to ensure that if one component fails, another component can take over seamlessly without causing any disruption to the storage access.
In addition to redundancy, SANs also provide other important features such as resiliency, security, and storage management. Resiliency ensures that the SAN can recover quickly from any failures or disruptions, while security ensures that the data stored on the SAN is protected from unauthorized access. Storage management features enable administrators to manage and monitor the storage resources in the SAN, such as provisioning new storage, monitoring usage, and configuring backups.
In summary, while all the options listed (recovery, redundancy, resiliency, security, and storage) are important features in a SAN environment, redundancy is the specific feature on the front end that provides high availability and fault tolerance for storage resources to clients accessing the same storage devices across the SAN.
