Cluster Storage FAQs

What makes multihost storage highly available?

Multihost storage is highly available because it can survive the loss of a single disk, because of mirroring (or because of hardware-based RAID-5 controllers). Because a multihost storage device has more than one host connection, it can also withstand the loss of a single node to which it is connected. In addition, redundant paths from each node to the attached storage provide tolerance for the failure of a host bus adapter, cable, or disk controller.
