Open-E DSS V7 is the XFS-based software in our portfolio, and a perfect solution for standard storage setups requiring failover, replication and other basic features. Find out more about the possibilities that the product is offering.
Fibre Channel (FC) Storage uses a high-speed network technology for data storage that has become a common connection type for SAN enterprise storage. It is especially suited for creating SAN topologies for virtualization, data center or other demanding platforms. The technology offers point-to-point, switched, and loop interfaces, and is designed to interoperate with SCSI.
The Avago Syncro™ technology is a solution for businesses of all sizes that require high available storage for high performance, high capacity or hybrid system. The Syncro™ CS solution is a hardware based, high-available DAS which is shared between two head-nodes. In combination with Open-E DSS V7 software, it is possible to create a customized solution for any need, from a high performance SSD storage to high capacity 3,5” HDD server with SDD caching.
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.
High Availability through Failover is crucial for many companies. Despite using high-quality hardware and superior connections, still any server can crash, leading to data loss. Providing High Availability can be tricky, but fortunately Open-E DSS V7 is able to work with a second node. It keeps data redundant and when aware of the original node’s failure, the redundant node continues serving clients; effectively replacing the missing node. This process is commonly known as Failover.
