A storage administrator is commissioning a new Huawei OceanStor Dorado 6800 V6 array. During the network planning phase, the administrator must configure both management and service network ports. The security policy requires complete isolation between management traffic and iSCSI service traffic. Which action is essential to meet this requirement?
A system administrator is investigating a performance degradation issue on a VMware vSphere environment connected to a Huawei OceanStor 5500 V6 hybrid array. Latency for a key virtual machine has suddenly increased. Analysis using DeviceManager shows that the storage pool's read cache hit ratio is below 10%, while disk utilization is consistently high. Which Huawei feature should be configured to most effectively address this read performance bottleneck?
A server administrator reports that a newly provisioned Linux server cannot see its assigned LUN from a Huawei OceanStor Dorado array. The storage team has confirmed the LUN is created and mapped to the correct host group. The Fibre Channel zoning is also verified as correct. What is the most likely cause of this connectivity issue from the host's perspective?
A financial institution is deploying a new Huawei OceanStor Pacific distributed storage cluster for archiving purposes. The primary goals are maximizing storage efficiency and ensuring data durability against multiple node failures. The data consists of large, immutable files. Which TWO of the following configurations should the architect choose to best meet these requirements? (Select TWO)
During routine maintenance, an administrator needs to perform a firmware upgrade on a controller in a high-availability OceanStor Dorado V6 cluster. To ensure services remain uninterrupted, this must be a non-disruptive upgrade (NDU). True or False: The administrator must first manually migrate all LUNs owned by the controller to be upgraded to its peer controller before starting the firmware update process.
An e-commerce company uses a Huawei OceanStor Dorado array for its order processing database. The company experiences peak traffic between 9 AM and 5 PM, during which database performance is critical. A separate, less critical batch reporting job runs on the same array overnight. The administrator needs to ensure the reporting job does not consume excessive I/O resources that could impact the next day's database performance. Which feature allows the administrator to set specific IOPS and bandwidth limits for the LUNs used by the reporting application?
A hospital is deploying a new Picture Archiving and Communication System (PACS) on a Huawei OceanStor storage system. The deployment plan requires creating a 50 TB file system. During the initial configuration on DeviceManager, which LUN feature must be enabled to allow the creation of a file system on that LUN?
An administrator receives a critical alarm on an OceanStor Dorado array indicating a 'Disk Fault'. Upon inspection, the indicator light on the corresponding disk is steady amber. The administrator has a spare disk of the same model and capacity on hand. What is the correct sequence of actions to resolve this issue? ```mermaid flowchart TD A[Start] --> B{Verify Hot Spare}; B --> C[Remove Faulty Disk]; C --> D[Insert New Disk]; D --> E{Check Rebuild Status}; E --> F[End]; ```
An administrator is responsible for a mixed-workload environment on a Huawei OceanStor Dorado V6. A high-priority online transaction processing (OLTP) application and a low-priority data analytics application share the same storage pool. The administrator needs to create a policy that guarantees a minimum of 4000 IOPS for the OLTP application at all times, while limiting the analytics application to a maximum of 1000 IOPS. Which SmartQoS policy type should be used for the OLTP application's LUNs?
A consultant is designing a disaster recovery solution for a client with two data centers located 100 km apart. The client requires a near-zero Recovery Point Objective (RPO) for a critical file system hosted on a Huawei OceanStor array. Due to network latency over the 100 km distance, synchronous replication is not feasible. Which Huawei feature provides the lowest possible RPO in an asynchronous remote replication scenario?
