Methods used to calculate the number of users that can be borne by the CPU of a single server

Methods used to calculate the number of users that can be borne by the memory of a single server

CPU models requirements
A server must use the same model of CPUs. Otherwise, the server cannot run normally.

How Many Firewalls Can a User Have?

A user can have a maximum of 200 firewalls. It is recommended that you configure a maximum of 20 inbound or outbound rules for each firewall. If more than 20 inbound or outbound rules are configured, the forwarding performance will deteriorate.


Method used to calculate RAID capacity
If the number of RAID member disks is N (excluding hot spare disks), available capacity of RAID 0 = N x disk capacity. Available capacity of RAID 1 = N x Disk capacity/Number of mirror groups Available capacity of RAID 3 = (N-1) x Disk capacity Available capacity of RAID 5 = (N-1) x Disk capacity Available capacity of RAID 6 = (N-2) x Disk capacity Available capacity of RAID 10 = N x Disk capacity/Number of mirror groups Available capacity of RAID 50 = (N-2) x Disk capacity
