[NAS] Some Reminders on Adding an NAS to Network


  • RAID 5 - needs at least 3 HDs
  • Either one among 3 is down, data can be recovered; for two, nothing can be done.
  • Using Reserved IP from DHCP is better, since when network is down, plugging NAS to another network with simple setting (DHCP giving random IP) and NAS can be used immediately
  • Setting Reserved IP requires the device's MAC address. Need to check the given IP and its MAC address from router
  • In windows, NAS drive can be searched by typing \\TheNASName\TheFolderCreated.
  • Only Disk Quota can be set. Cannot set a quota for a created folder. Thus the users can share the resources among a disk, but not a folder. If allocation for different users is needed, created different disks.
