Chapter 6. Volume configuration 323
HyperSwap volumes are a new type of HA volumes that are supported by IBM Spectrum
Virtualize. They are built off two existing IBM Spectrum Virtualize technologies:
Metro Mirror
Volume Mirroring
These technologies have been combined in an active-active configuration deployed by using
Change Volumes (as used in the Global Mirror with Change Volumes) to create a Single
Volume (from a host perspective) in an HA form. The volume presented is a combination of
four “traditional” volumes but is a single entity from a host (and administrative) perspective as
shown in Figure 6-38.
Figure 6-38 What makes up a HyperSwap Volume
The GUI simplifies the complexity of HyperSwap volume creation by only presenting the
volume class of HyperSwap as a Volume Creation option after HyperSwap topology has
been configured.
