SnapServer 4100 Disk Configurations

By: Sander Sassen

Quantum is one of the manufacturers that started manufacturing NAS servers early on. Their SnapServer product line features a broad range of different models, with different disk configurations and storage capacities. The Snap Server 1000 is offered in 20GB and 40GB capacities, the Snap Server 2000 provides 80GB, and the Snap Server 4100 comes with up to four 75GB drives, configurable up to 300GB, depending on its RAID configuration. The theoretical maximum capacity is dependent upon available drive technology. Quantum expects increased drive capacities to become available in the future and is will be releasing higher capacity SnapServers once drive are commonly available. In this review we'll be taking a look at their SnapServer 4100, equipped with four 30GB harddrives, 120GB total storage capacity, that can be configured as described below:

  • Each disk is an individual unit, which network users can access as an independent storage device
  • Combine any two to four disks as a single larger disk that has no data protection. This configuration is known as disk striping or RAID 0. Disk striping is best suited for applications where maximum performance and highest capacity are more important than data protection
  • Combine any two disks, using one disk to duplicate the data stored on the other. This configuration is called disk mirroring, or RAID 1. If either disk in the configuration fails, the other automatically takes over, the server continues operating without interruption or data loss. Total storage capacity is reduced by half, to provide the highest possible level of data protection
  • Configure a RAID 5 disk array with fewer than four disks, however a minimum of three disks is required. The fourth disk can be configured as a single unit or as a spare, to automatically replace a failed drive in the RAID 5 array

The screenshots below give a good impression of how the disk configuration screens and options look like when the server is being accessed from a web browser. As is obvious from the screenshots we've configured the disks in our SnapServer as an RAID 5 array, resulting in a total capacity of 83.9 GB.
