In the event of a SAN-attached G10 node failure, which LUN configuration will maintain access to a given set of data LUNs?
- A. HCP LUN replicator
- B. Zero Copy Failover
- C. Data Protection Level 2
- D. Dynamic multi-pathing
正解：D
解説：
Dynamic Multi-Pathing (DMP) is a method that ensures continuous access to data in the event of a node failure or path failure within a SAN environment. When a SAN-attached G10 node in a Hitachi Content Platform (HCP) fails, DMP allows for automatic rerouting of data traffic to an alternate path without interruption. This is accomplished by creating multiple physical paths between the storage devices and the servers, ensuring that if one path fails, another can be utilized, thereby maintaining access to data LUNs.
Hitachi Vantara Content Platform Installation Reference:
Dynamic Multi-Pathing (DMP): In the context of HCP, DMP is critical for high availability and fault tolerance. It enables redundancy in connectivity between nodes and storage arrays, ensuring continuous data access and minimal service disruption in the event of hardware failure. This technology is designed to work in SAN environments where multiple paths are configured between storage and compute resources.
SAN-Attached G10 Node Failure: If a G10 node experiences failure, DMP comes into play by dynamically redirecting I/O operations from the failed path to an alternative path, ensuring uninterrupted access to data stored in the associated LUNs.
By using DMP, the system effectively prevents data loss or access interruption, which is why this configuration is recommended for maintaining LUN access during node failures in a SAN-attached HCP environment
