Target entity: SCSI over RDMA Context triple: [STORM Working Group, focusesOn, SCSI over RDMA]
-
A.
Fibre Channel over IP
Fibre Channel over IP is a storage networking technology that encapsulates Fibre Channel frames within IP packets to enable long-distance connectivity between Fibre Channel SANs over IP networks.
-
B.
NVMe over Fabrics
NVMe over Fabrics is a network protocol that extends the high-performance NVMe storage interface across various network transports to enable low-latency, scalable access to remote solid-state storage.
-
C.
RDMA
RDMA (Remote Direct Memory Access) is a high-performance networking technology that allows one computer to directly access the memory of another without involving the operating system or CPU, significantly reducing latency and CPU overhead in data transfers.
-
D.
IP over InfiniBand
IP over InfiniBand is a networking technology that enables standard Internet Protocol (IP) traffic to run over high-speed InfiniBand fabrics, allowing IP-based applications to leverage InfiniBand’s low latency and high bandwidth.
-
E.
SCSI Stream Commands (SSC)
SCSI Stream Commands (SSC) is a SCSI command set standard primarily used for controlling and managing streaming devices such as tape drives.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Input
Subject: SCSI over RDMA Description of subject: SCSI over RDMA is a storage networking protocol that enables SCSI commands to be transported efficiently over Remote Direct Memory Access–capable networks for high-performance, low-latency data access.
