When two OceanStor Dorado 18000 controller enclosures are used, data access is not affected even if multiple controllers are faulty. Which of the following can be tolerated by Dorado 18000? (Select all that apply)
The high-end OceanStor Dorado 18000 series is designed with the SmartMatrix 4.0 full-mesh architecture, which provides the industry ' s highest level of controller redundancy. In a standard configuration with 8 controllers (housed in two enclosures), the system can tolerate extreme failure scenarios without service interruption:
Individual Failures (Option A, C): The system easily handles the failure of one or two controllers as the remaining controllers take over the workload transparently.
Extreme Controller Failure (Option B): Due to the full-mesh interconnect where all controllers share a global memory cache and can access all backend disks, the system can tolerate the failure of up to seven out of eight controllers . As long as one controller remains active, services continue.
Enclosure Failure (Option D): Because the architecture is mirrored across controller enclosures, the entire failure of one controller enclosure (containing 4 controllers) is tolerated.
This level of resilience ensures that mission-critical applications remain online even in the face of catastrophic hardware events, maintaining 99.9999% availability.
