Sep 14, 2022Is RAID10 a protocol? Leaning towards FC and iSCSI

Sep 15, 2022https://docs.netapp.com/us-en/ontap/san-admin/lun-san-environments-concept.html "The FC protocol and iSCSI protocol both provision storage through the use of LUNs" I think you're correct.
Rob69420Options: CF
Sep 16, 2022A LUN is used by a transport protocol associated with an SCSI, iSCSI, Fibre Channel (FC) or similar interface. LUNs are central to the management of block storage arrays shared over a SAN.

Apr 15, 2023C. iSCSI F. FC To share disks between the nodes of a database cluster to access the same LUN, the company should use either iSCSI or FC protocols. Both of these protocols provide block-level access to shared storage, allowing multiple nodes to access the same LUN simultaneously.

Jul 22, 2023The answer is C and E. iSCSI and NFS. iSCSI is a network protocol that allows block-level storage to be shared over a network. This makes it a good choice for sharing disks between the nodes of a database cluster. NFS is a file-level sharing protocol that allows files to be shared over a network. This makes it a good choice for sharing files between the nodes of a database cluster. The other protocols listed are not suitable for sharing disks between the nodes of a database cluster. CIFS and FTP are file-level sharing protocols that are not designed for sharing block-level storage. RAID 10 is a type of RAID that provides fault tolerance, but it does not allow disks to be shared between nodes. FC is a Fibre Channel protocol that is designed for high-performance storage, but it is not as widely supported as iSCSI or NFS.

Jul 22, 2023Correction: i reverse back my answer to C. iSCSI & F. FC (Fibre Channel) FC (Fibre Channel): FC is a high-speed storage area network (SAN) protocol that provides block-level access to storage devices. It allows multiple servers to share the same storage LUN over a dedicated and high-performance Fibre Channel fabric. FC is often used in enterprise-level environments where high performance and low latency are critical, such as database clusters. NFS (Network File System): NFS is a file-level protocol used for sharing files over a network. Like CIFS, it does not offer the block-level access required for shared disks in a database cluster.

Mar 11, 2024RAID10 has nothing to do with sharing disks. Sure it's nice and import, but not relevant to the question. ChatGPT type answer

Jul 18, 2024C. iSCSI - Internet Small Computer Systems Interface (iSCSI) is a protocol that allows clients (called initiators) to send SCSI commands to SCSI storage devices (targets) on remote servers. It is used to facilitate data transfers over intranets and to manage storage over long distances. F. FC - Fibre Channel is a high-speed network technology primarily used to connect computer data storage. Fibre Channel is especially suited for connecting servers to shared storage devices and is used in storage area networks (SANs).
