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.
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
With iSER the target drives all data transfer (with the exception of iSCSI unsolicited data) by issuing RDMA write/read operations, respectively. When the iSCSI layer issues an iSCSI command PDU, it calls the Send_Control primitive, which is part of the DI. The Send_Control primitive sends the STag with the PDU.
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Gluster, Lustre and old (1.6.x) version of MooseFS, although this document is from 2013 and a lot of information are outdated (e.g. MooseFS had no HA for Metadata Server at that time).
Since PVE 8.1 there is a full Software-Defined Network (SDN) stack implemented and is compatible with Secure Boot. [22] Guest machine backups can be done using the included standalone vzdump tool. [23] PVE can also be integrated with a separate Proxmox Backup Server (PBS) using a web GUI, [24] or with the text-based Proxmox Backup Client ...
Recently other protocols for this field, like iSCSI and ATA over Ethernet have been developed as well. Confusingly, drives usually use copper twisted-pair cables for Fibre Channel, not fibre optics. The latter are traditionally reserved for larger devices, such as servers or disk array controllers.
In computing, the Global File System 2 (GFS2) is a shared-disk file system for Linux computer clusters. GFS2 allows all members of a cluster to have direct concurrent access to the same shared block storage, in contrast to distributed file systems which distribute data throughout the cluster.
