Hard and soft limits

• A Hard limit is the maximum amount of a virtual resource (e.g. RAM) that an entity will be allowed to consume. 
• A Soft limit warns users and administrators that the entity is running out of a resource.

The rules for creating allocation limits are as follows:

• You cannot have a hard limit only
• Soft limits must always be less than or equal to hard limits
• When a limit is equal to 0, it means that there is no limit to resource usage at this level

• When editing limits, you cannot set the hard limits below the existing resource usage, except for Local hard disk
