Triple

Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases). For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).

Phrase: DataNode | Statement: [HDFS, storesBlocksOn, DataNode]

Target entity: DataNode
Context triple: [HDFS, storesBlocksOn, DataNode]

• A. Secondary NameNode
  The Secondary NameNode is an auxiliary HDFS service that periodically checkpoints and merges filesystem metadata to help keep the primary NameNode’s namespace image compact and manageable.
• B. HDFS
  HDFS (Hadoop Distributed File System) is a fault-tolerant, distributed file system designed to store and manage large volumes of data across clusters of commodity hardware.
• C. Netnod
  Netnod is a Swedish internet infrastructure organization that operates critical core services such as internet exchange points, DNS root server instances, and time and frequency distribution.
• D. GlusterFS
  GlusterFS is a scalable, distributed file system that aggregates storage resources across multiple servers into a single, networked filesystem.
• E. Storage Area Network
  A Storage Area Network (SAN) is a high-speed, specialized network that provides block-level access to consolidated storage, enabling servers to share centralized disk resources for improved performance, scalability, and manageability.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Generate a one-sentence description of the target entity. 
You are given a context triple in the form (subject, predicate, object), where the object is the target entity. 
# Instructions
Use the triple to infer relevant information about the entity. Describe the entity based on what is most defining, well-known. 
Avoid repeating the information from the triple, unless really essential.
# Response Format
Return only the sentence: "Description: [one-sentence description of the target entity]"

Entity: DataNode
Triple: [HDFS, storesBlocksOn, DataNode]

DataNode is a core component of Hadoop's HDFS responsible for storing actual data blocks on local storage and serving read/write requests from clients and the NameNode.
