Fill in the Form to Continue

Published: December 7, 2017


In addition to the industry-standard uplink protocols, StarWind Virtual SAN supports iSER, the topnotch data transfer extension of iSCSI for RDMA. The protocol has low latency and CPU utilization. What is more, it has inherited from iSCSI its security and simplicity advantages. With RDMA protocol suite, iSER supplies higher bandwidth for block storage transfers. These features are crucial for building virtualized or cloud environments, where the protocol allows boosting VMs’ migration and data replication.

This guide is intended for experienced StarWind users, Windows system administrators, and IT professionals who would like to enable the iSER feature in StarWind Virtual SAN.

A full set of up-to-date technical documentation can always be found here, or by pressing the Help button in the StarWind Management Console.

9. Check whether the iSER feature has been Enabled successfully.



When it comes to virtualized or cloud environments, storage network is the most crucial factor in their overall performance and stability. Enabling iSER allows increasing the speed of VM migration, data and VM replication. Apart from that, iSER provides all the advantages of the iSCSI protocol while adding low latency and direct memory access, allowing to configure a high performing and redundant system.
