In addition, you can enter a range of hosts using common IP range expressions such as: 192. 168. 2. , 192. 168. 2. 0/255. 255. 255. 0, 192. 168. 2. 0/24 These designations all allow hosts with IP addresses 192. 168. 2. 1 through 192. 168. 2. 254.

The names must be valid accounts, either on the ReadyNAS or on the domain controller. [. . . ] The user, group, or share with a set quota cannot exceed disk usage beyond this limit. Quota is typically specified to ensure that no one user, group, or share abuses the available storage space. Basically it is a method of storing data on multiple disks in a way that if one disk fails, data can still be accessed from the other disks. A RAID level selects how data will be kept redundant, the most popular of which are levels 0, 1, and 5. [. . . ]
