Massive actually. The most wanted and highly anticipated functionality became available in the new Data Storage Software Version 7. After many months of testing, tuning and improving the Active-Active Automatic Failover for iSCSI, our company was ready with a product that not only meets industry standards but exceeds them.<\/strong><\/p>\n<h3 style=\"text-align: left;\"><span style=\"color: #000000;\">So, what is Active-Active anyway?<\/span><\/h3>\n<p style=\"text-align: left;\"><span style=\"color: #44434b;\"><strong>Active-Active Automatic Failover for iSCSI<\/strong><\/span> is a crucial Data Storage functionality used for Cloud Storage, High Availability, Business Continuity, Storage for Virtualization, and many more. This feature enables you to simultaneously run volumes in the active mode on two nodes, thus providing <a title=\"high availability\" href=\"https:\/\/www.open-e.com\/solutions\/high-availability\/\">high availability of data<\/a>. If one node fails, the other one takes over automatically and all application services continue to run without interruption. Once the failed node is available again in the resource pool, the storage administrator can move the activity of selected volumes back to the node of choice. Thanks to this option, overall cluster performance is improved since the read, write and replication traffic can be balanced on both nodes.<\/p>\n<p style=\"text-align: left;\">Below you will see a video of how to quickly set up the <a title=\"Active-Active Failover for iSCSI\" href=\"https:\/\/www.open-e.com\/products\/automatic-failover-iscsi-volumes\/\">Active-Active iSCSI Failover<\/a> in Open-E DSS V7.<\/p>\n<p><iframe loading=\"lazy\" src=\"https:\/\/player.vimeo.com\/video\/46075875\" width=\"500\" height=\"375\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n<p><a href=\"https:\/\/vimeo.com\/46075875\">Open-E DSS V7 Active\/Active iSCSI Failover Setup<\/a> from <a href=\"https:\/\/vimeo.com\/opene\">Open-E<\/a> on <a href=\"https:\/\/vimeo.com\">Vimeo<\/a>.<\/p>\n<p>&nbsp;<\/p>\n<h3><span style=\"color: #000000;\"><strong>Open-E DSS V7 Active-Active Cluster Advantages:<\/strong><\/span><\/h3>\n<ul>\n<li><span style=\"color: #3d3d3d;\">Configuring Active-Active clusters can be done without shared (common) discs<\/span><\/li>\n<\/ul>\n<ul style=\"text-align: left;\">\n<li><span style=\"color: #3d3d3d;\">Validation on each node and I\/O error triggers, so clusters can\u2019t be started with the wrong configuration (e.g. one LUN is not in a cluster)<\/span><\/li>\n<\/ul>\n<ul style=\"text-align: left;\">\n<li><span style=\"color: #3d3d3d;\">Speeds up networking connectivity, since I\/O traffic is equally balanced on two nodes<\/span><\/li>\n<\/ul>\n<ul style=\"text-align: left;\">\n<li><span style=\"color: #3d3d3d;\">Ping Nodes can be configured<\/span><\/li>\n<\/ul>\n<ul style=\"text-align: left;\">\n<li><span style=\"color: #3d3d3d;\">Fully utilizes all processing power on both cluster nodes<\/span><\/li>\n<\/ul>\n<ul style=\"text-align: left;\">\n<li><span style=\"color: #3d3d3d;\">You can configure as many Auxiliary paths as many network connections you have<\/span><\/li>\n<\/ul>\n<ul>\n<li><span style=\"color: #3d3d3d;\">Almost doubles your overall performance<\/span><\/li>\n<\/ul>\n<p>In addition, by radically simplifying the <strong>iSCSI failover<\/strong> configuration and adding helpful status icons in Open-E\u2019s DSS V7, administrators can now easily navigate the software and use Active-Active Automatic Failover for iSCSI. Within a few minutes, you can have up to several hundred gigabytes available on your network \u2013 without much effort and no downtime.<\/p>\n<p>Furthermore, when looking at our competitors <strong>Active-Active software<\/strong>, we noticed many missing functionalities if compared to the Open-E DSS V7 Active-Active Automatic Failover for iSCSI. These disadvantages included: DNS required for auxiliary communication, no option to configure ping nodes, only 2 Auxiliary connections can be configured or only one big single point of failure (shared storage array) can be used. Keep these flaws in mind when choosing your storage software.<\/p>\n<p>It turns out that other offerings can give you Active-Active solutions OR offer a reasonable price and configuration, but very few can deliver <strong>BOTH <\/strong>at the same time. And that\u2019s precisely what our Open-E DSS V7 does. It provides superior performance, security, and scalability at a fraction of the cost of alternative storage solutions. The flexible design of Open-E DSS V7 enables organizations of all sizes to create effective NAS and\/or IP-SAN\/iSCSI solutions that can adapt to and meet the simplest or the most complex storage needs.<\/p>\n<p><strong>The Automatic Active-Active Failover functionality for iSCSI Volumes can only be purchased with Open-E DSS V7<\/strong>.
