Link xStack Storage system is an intelligent, high-performance Gigabit Ethernet (GbE) or 10GbE storage solution designed for businesses that want to improve the reliability, availability, serviceability , initiator, target, network portal, and Link Aggregation Group (LAG) features.

commands and data formats used for secondary services such as authentication). From the network's perspective, iSCSI is just another service is conceptually similar to TCP/IP's client/server architecture. Every SCSI link involves a host adapter, called an initiator, and a storage device 's Guide 3 - D-Link DSN-4100 | Software User's Guide for DSN-4000 - Page 14
in the creation of a new Volume any time it is required. That drive is automatically moved to the Base Pool at that time with no manual interaction. Disk drives currently being used to hold Volume data or ready to be used to hold volume data. A drive that can only be used - D-Link DSN-4100 | Software User's Guide for DSN-4000 - Page 15
of the space used by that volume is not available to the initiator. The 10 GB volume can also be created using 2.5 GB members if five members are size x bytes, the xStack Storage system needs 2x bytes, or 100%). For a stripe mirror organization, the xStack Storage system distributes volume Guide 5 - D-Link DSN-4100 | Software User's Guide for DSN-4000 - Page 16
characteristics of the volume. The storage system then determines the remaining parameters needed to allocate the storage space and create the volume. Manually: You can select the organization and all other parameters described above and either selects the drives that can be used for the volume - D-Link DSN-4100 | Software User's Guide for DSN-4000 - Page 17
a good rule of thumb to follow is to have sufficient capacity to support the total capacity of the current and new volumes. For example, to reconfigure a 100 GB volume to 150 GB, you should have a total of 250 can access the storage system. xStack Storage Management Center Software User's Guide 7 - D-Link DSN-4100 | Software User's Guide for DSN-4000 - Page 18

Understanding the System Administration View The System Administration View varies depending on whether your xStack Storage system is capable of supporting single or redundant controllers. Dual-controller configurations are only available when an additional controller is installed in the system, and - D-Link DSN-4100 | Software User's Guide for DSN-4000 - Page 93
note: For the DSN-5110-10, the additional controller is the DSN-510, for the DSN5210-10, the additional controller is the DSN-520 and for the DSN-5410-10, the additional controller is the DSN-540. Please note , as shown in Figure 6-3. xStack Storage Management Center Software User's Guide 83 - D-Link DSN-4100 | Software User's Guide for DSN-4000 - Page 94
Dual controller systems provide redundancy for High Availability. Under normal conditions, both controllers in the Primary Array function as a "Bound" pair. They operate together and all system activity on the primary controller is mirrored to the redundant controller.
