VCE Vblock™ Systems Series 700 Architecture Overview
Recommended configurations
The recommended configurations for the Vblock Data Protection solution for business continuity and workload
mobility are:
Configuration Description
Non cross-
cluster connect
•
Delivers zero Recovery Point Objective (RPO) in all single failures including that of an entire
site
•
Delivers zero Recovery Time Objective (RTO) in the event of a storage array failure
• For a server domain failure or EMC VPLEX failure, limits RTO to the application restart time
• Requires a ping round-trip time of less than five milliseconds
Cross-cluster
connect
Servers in cross-cluster connect configuration can access data from the EMC VPLEX cabinet at
either site. Cross-cluster connect is suitable for deploying within a campus, or in multiple isolated
zones within a single data center. This configuration eliminates the need to do server failover
when an entire storage cluster (EMC VPLEX) or the storage behind it) goes down.
A cross-cluster configuration:
•
Delivers zero RPO in all single failures including that of an entire site
• Delivers zero RTO in the event of a storage domain failure
•
For a server domain failure, limits RTO to the application restart time
•
Requires a ping round-trip time of less than one millisecond
