Designing for Node Failure:
Ensuring a PowerStore solution performs optimally even in the event of a node failure requires careful consideration of performance thresholds.
Max Performance Saturation:
Setting the Max Performance Saturation to 50% during the sizing process ensures that in the event of a node failure, the remaining node can handle the load without performance degradation.
This conservative approach allows the system to operate within safe performance limits, maintaining high availability and performance.
Other Options:
Disaster Recovery Site: Important for overall business continuity but does not directly address performance during a node failure within the same site.
Performance Growth: Setting Performance Growth to 50% focuses on future growth rather than immediate redundancy considerations.
Higher Model: While providing a higher model can offer more resources, it is not as cost-effective as optimizing the performance saturation setting.
