StarWind iSCSI Accelerator

Value Proposition

To maximize performance of Hyper-V VMs and the applications that use iSCSI-attached storage, StarWind introduces free iSCSI Accelerator. The Accelerator eliminates the Microsoft iSCSI Initiator performance bottleneck by automatically distributing iSCSI workloads among all available CPU cores. As a result, users can streamline CPU resource utilization without fine-tuning Microsoft iSCSI Initiator or buying a hardware load balancer.

Unlike the hardware accelerators, StarWind iSCSI Accelerator can be installed on any Hyper-V server with no proprietary hardware needed. Furthermore, the solution is much easier to set up for workload distribution than Windows iSCSI Initiator. The Accelerator is basically good to go from the moment it is deployed.



StarWind iSCSI Accelerator takes Hyper-V VMs and Windows Server applications performance to an entirely new level by properly distributing iSCSI workloads among all the available CPU cores. No more “single CPU core bottleneck” – benefit from the maximized IOPS and CPU utilization.


Save the time used for trying to fine-tune Microsoft iSCSI Initiator performance. StarWind iSCSI Accelerator is deployed into any Windows system in less than a minute.


StarWind iSCSI Accelerator is free of charge. No hidden costs or payments. No additional hardware or software required. Just because VMs and applications running on the Windows Server platform deserve proper performance.
