As a result, iSCSI is often seen as a low-cost alternative to Fibre Channel, which requires dedicated infrastructure except in its FCoE (Fibre Channel over Ethernet) form. However, the performance of an iSCSI SAN deployment can be severely degraded if not operated on a dedicated network or subnet (LAN or VLAN ), due to competition for a fixed ...
iSNS provides management services similar to those found in Fibre Channel networks, allowing a standard IP network to operate in much the same way that a Fibre Channel storage area network does. Because iSNS is able to emulate Fibre Channel fabric services and manage both iSCSI and Fibre Channel devices, an iSNS server can be used as a ...
Fibre Channel (FC) is a successor to parallel SCSI interface on enterprise market. It is a serial protocol. In disk drives usually the Fibre Channel Arbitrated Loop (FC-AL) connection topology is used. FC has much broader usage than mere disk interfaces, and it is the cornerstone of storage area networks (SANs).
The Fibre Channel SAN connects servers to storage via Fibre Channel switches. Storage area networks (SANs) are sometimes referred to as network behind the servers [2]: 11 and historically developed out of a centralized data storage model, but with its own data network. A SAN is, at its simplest, a dedicated network for data storage.
In this regard it is more comparable to Fibre Channel over Ethernet than iSCSI. With fewer protocol layers, this approach makes AoE fast and lightweight. It also makes the protocol relatively easy to implement and offers linear scalability with high performance. The AoE specification is 12 pages [1] compared with iSCSI's 257 pages. [2] AoE ...
In computer storage, a logical unit number, or LUN, is a number used to identify a logical unit, which is a device addressed by the SCSI protocol or by Storage Area Network protocols that encapsulate SCSI, such as Fibre Channel or iSCSI. [1]
Initiator and target terms are applicable not only to traditional parallel SCSI, but also to Fibre Channel Protocol (FCP), iSCSI (see iSCSI target), HyperSCSI, (in some sense) SATA, ATA over Ethernet (AoE), InfiniBand, DSSI and many other storage networking protocols.
LIO supports a wide range of storage protocols and transport fabrics, including but not limited to Fibre Channel over Ethernet (FCoE), Fibre Channel, IEEE 1394 and iSCSI. [citation needed] It is utilized in several Linux distributions and is a popular choice for cloud environments due to its integration with tools like QEMU/KVM, libvirt, and ...
