Services - Superna ™ Eyeglass PowerScale DR Design and Implementation


This service ensures  the highest level of DR readiness possible for PowerScale customers with Superna Eyeglass. Recommended For: For customers that prefer to have Superna PS recommend and validate  customer implementation of cluster, DNS, AD changes and validate the end to end design and implementation to achieve high level of confidence the key business data is protected for all possible DR impacts.  Customers that view DR investments as a way to achieve continuous operations level of storage availability.

  1. Description:  This service is a stand alone service  that provides PowerScale cluster remote implementation of cluster DR configuration  required for failover using one of the supported failover modes (Access Zone dual delegation, SyncIQ or DFS mode).  The  configuration changes will also address SyncIQ best practices to enable a robust DR solution with PowerScale and Superna  ™ Eyeglass.   In addition, DR Readiness automation will be configured to ensure continuous DR testing is fully automated using the RunBook Robot feature in Superna ™ Eyeglass
