*The minimum number of servers per cluster is 3, although using 4 is recommended. A single server configuration is also allowed, but this setup does not support clustering. The server can be configured as either a single or dual instance.
**The minimum number of domains is 3.
***The minimum number of disks per instance is 6 with EC enabled, although using at least 8 is recommended. The minimum number of disks per instance is 4 with EC not enabled, although using at least 6 is recommended.
Lightbits does not track clones as a separate resource. A clone is simply a volume created from a snapshot. The Maximum number of volumes limit is the total across all volume types in the cluster - regular volumes and clones combined.
