* 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.
