Disaster Recovery is one of the most essential strategies for securing lost data against disasters. It includes all processes and procedures that are performed in order to prevent large failures and to avoid the consequences by keeping copies of data. With a consistent strategy, you are able to quickly recover business-critical files and applications of your IT infrastructure - ensuring business continuity and minimization of data loss.

The Failover feature provides High Availability of data. In an iSCSI Failover setup of two servers, data is saved on both servers simultaneously. When one system fails, its processes and all resources are being relocated to and restarted on the second node. The Active-Passive setup allows having all volumes active on one node (the primary node), while the other node has all passive copies and takes over the tasks in case of an emergency (the secondary node). A load-balanced Active-Active Failover on the other hand, doesn’t have a primary or secondary node. It adds extra performance by enabling the user to decide which volumes are active on which node. The failover process is the same, but the servers are able to utilize their full network performance and eliminate the unnecessary cost of idle hardware.

iSCSI (Internet Small Computer System Interface) is a type of protocol providing a proficient usage of disk space together with data safety and increased performance. A centralized storage management that uses iSCSI and RAID technologies enables a comfortable administration and reduced downtime in case of a hard drive failure. It enables building SAN (Storage Area Network) storage systems using SCSI disk arrays and Ethernet (TCP / IP). Its main advantage is the ability to create an iSCSI SAN with an extensive use of typical networking elements which facilitates system building and reduces its costs.

Having a highly available storage is one thing, but what about its overall performance? Learn how you can achieve both, using Open-E DSS V7 with iSCSI Active-Active Feature Pack.
