Link aggregation is a method used to combine multiple network connections in parallel to increase throughput and provide redundancy in case one of the links fail. This feature is used in network appliances, including FortiAnalyzer, to add redundancy to the network connections, ensuring that there is a backup path for traffic if the primary path becomes unavailable.

RAID level affects how much disk space is reserved for redundancy and fault tolerance. For example, RAID 1 mirrors data, meaning you need more space for redundancy, while RAID 5 or RAID 6 reserves space for parity.
Disk size directly influences the total available and reserved space since the larger the disk, the more space may need to be reserved for system functions, logs, and other operations.
The total quota and license type do not directly impact the reserved disk space, though they do influence other aspects of capacity and functionality.
