Question 11 - D-XTR-DY-A-24 discussion

In an environment with multiple XtremIO X1 clusters running different versions of XtremIO software, the minimum number of XtremIO Management Servers (XMS) required is determined by the compatibility and management requirements of the clusters.

Compatibility Check: Verify the compatibility of XMS with different versions of XtremIO software. An XMS can manage clusters running the same major version of software.

Management Requirements: Assess the management requirements for the clusters. Each XMS can manage multiple clusters, but there may be limitations based on the software version and scalability limits.

Scalability Limits: Consider the scalability limits of the XMS. For example, an XMS managing multiple clusters may have a global limit on the number of volumes it can manage across all clusters1.

Determine the Minimum Number: Based on the above factors, determine the minimum number of XMS servers required. In this case, since there are two distinct software versions (4.0.4-41 and 3.0.3-11), at least two XMS servers would be needed---one for each software version group.

Official Documentation: Consult the official Dell XtremIO Deploy Achievement document for specific guidelines and instructions. The document will provide the authoritative steps and references for setting up and managing the XMS in a multi-cluster environment.

In conclusion, for four XtremIO X1 clusters with two different software versions, a minimum of two XMS servers is required---one for the clusters running software 4.0.4-41 and another for those running software 3.0.3-11. This ensures proper management and compatibility across the clusters.
