15. What different kinds of the protocol are there for usage in NetApp?

Ans. NetApp supports various protocols to take special care of various data access necessities. These include NFS (Network File System) and CIFS (Common Internet File System) for file-based access, and iSCSI and FCP (Fiber Channel Protocol) for block-based storage access. Each of these serve particular use cases in the big business data ecosystem.

16. Illustrate the differences between Iscsi And Fcp?

Ans. iSCSI and FCP are both utilized for block storage in NetApp systems, but they vary in their application and execution. iSCSI communicates data over standard IP networks, making it more flexible and practical. In contrast, FCP requires a dedicated fiber channel network that offers better execution and speed and is reasonable for ecosystems with extensive data throughput needs.

17. Illustrate the differences between Ndmp Copy And Vol Copy.

Ans. NDMP Copy and Vol Copy in NetApp work for various data replication needs. NDMP Copy is principally utilized to support up information to tape using the Network Data Management protocol, which is ideal for long-term archives. Vol Copy, then again, is used to imitate whole volumes inside the equivalent or across various aggregates critical for data relocation and disaster recovery situations.

18. What is the port number for iSCSI?

Ans. The standard port number for iSCSI in NetApp and other capacity systems is 3260. This port is utilized for iSCSI connections, working with block-level data movement through IP networks.
