Why Your Next Migration Shouldn't Be a Host-Based Slog: Hitachi's Storage Hack Changes the Game
Hitachi Vantara has developed a storage offload capability for its VSP One arrays that dramatically accelerates virtual machine migrations to Red Hat OpenShift Virtualization by shifting data movement from host-based network transfers to high-performance storage-layer operations.

Hitachi’s storage offload capability with VSP One arrays changes how data moves during migration. Rather than transferring VM data through host-based network connections, storage offload uses the high-performance data movement capabilities built into enterprise storage arrays. The migration process shifts to the storage layer itself, where purpose-built hardware can move data far more efficiently
The technology integrates directly with Red Hat's Migration Toolkit for Virtualization, delivering migration speeds up to ten times faster than traditional methods and reducing timelines from months to as little as one week. This approach minimizes duplicate infrastructure costs, operational risks, and business disruption during modernization initiatives. Hitachi also extends enterprise-grade disaster recovery and high availability features to OpenShift Virtualization environments, matching the resilience organizations expect from legacy platforms.
