Zero-copy failover behavior

In a SAIN system, zero-copy failover is the process of one node automatically taking over management of storage previously managed by another node that has failed. Support for zero-copy failover is configured at the storage tier and enabled in the HCP system configuration.

Zero-copy failover is supported for storage nodes only.

This chapter describes the storage setup required to support zero-copy failover and explains how zero-copy failover works.
