Sharing the EMC VMAX system between a host and a Storwize V3700 clustered system

There are restrictions for sharing EMC VMAX systems between a host and the Storwize® V3700 system.

An EMC VMAX system can be shared between a host and the Storwize V3700 system under the following conditions:
  • When possible, avoid sharing target ports between the Storwize V3700 system and other hosts. If you cannot avoid this situation, you must regularly check the combined I/O workload that is generated by the Storwize V3700 system and the other hosts. The performance of either the Storwize V3700 system or the hosts is affected if the workload exceeds the target port capabilities.
  • A single host must not be connected to both the Storwize V3700 system and an EMC VMAX because the multipathing drivers (for example, subsystem device driver [SDD] and PowerPath) cannot coexist.
  • If the EMC VMAX is configured in such a way that other hosts cannot access the LUs that are managed by the Storwize V3700 system, other hosts can be directly connected to an EMC VMAX system at the same time as the system.
