SIOS SANless clusters High-availability Machine Learning monitoring
Definition: When clustering software detects a failure in the primary cluster node, it moves operation of the SQL Server to the secondary node in the cluster in a process called failover. Since the secondary node has access to the same data as the primary node, operation continues without downtime or data loss.

Definition: A recovery database (RDB) is a function in some email systems that facilitate recovery in the event of a failure. RDB enables email system administrators to mount and extract data from a restored mailbox database as part of a recovery operation in order to recover data from a backup or copy of a database without disrupting user access to current data.

Definition: SAN stands for storage area network. SANs is a network of storage devices shared by servers. It provides block-level storage that can be accessed by the applications running on any networked servers. Traditional failover clusters require shared storage (typically SAN) so that in the event of a failover the secondary cluster node has access to the same, up-to-date data as the primary node.
