Some researchers have made a functional and experimental analysis of several distributed file systems including HDFS, Ceph, Gluster, Lustre and old (1.6.x) version of MooseFS, although this document is from 2013 and a lot of information are outdated (e.g. MooseFS had no HA for Metadata Server at that time).
Internet Small Computer Systems Interface or iSCSI (/ aɪ ˈ s k ʌ z i / ⓘ eye-SKUZ-ee) is an Internet Protocol-based storage networking standard for linking data storage facilities. iSCSI provides block-level access to storage devices by carrying SCSI commands over a TCP/IP network. iSCSI facilitates data transfers over intranets and to manage storage over long distances.

NFS, SMB, FC, FCoE, iSCSI SPECsfs2008 is the latest version of the Standard Performance Evaluation Corporation benchmark suite measuring file server throughput and response time, providing a standardized method for comparing performance across different vendor platforms. EMC DSSD D5 Flash
The principal motivation was an attempt to mitigate the performance issue of the synchronous write operation in NFS Version 2. [6] By July 1992, implementation practice had solved many shortcomings of NFS Version 2, leaving only lack of large file support (64-bit file sizes and offsets) a pressing issue.
iSCSI: The "target-utils" iscsi package on many Linux distributions. NVMe-oF: an equivalent mechanism, exposing block devices as NVMe namespaces over TCP, Fibre Channel, RDMA, &c., native to most operating systems; Loop device: a similar mechanism, but uses a local file instead of a remote one
A common performance measurement of a clustered file system is the amount of time needed to satisfy service requests. In conventional systems, this time consists of a disk-access time and a small amount of CPU-processing time. But in a clustered file system, a remote access has additional overhead due to the distributed structure.
Requests for the data and its location are sent over conventional NFS to the NAS system. Block data is sent and retrieved directly from the storage device via iSCSI or Fibre Channel. Retrieving data directly from the storage device increases performance by eliminating the file system and protocol overhead associated with NFS or SMB.
