What is iSCSI and how is it connected?
iSCSI is a block protocol for storage networking and runs the very common SCSI storage protocol across a network connection which is usually Ethernet. iSCSI, like Fibre Channel, can be used to create a Storage Area Network (SAN). iSCSI traffic can be run over a shared network or a dedicated storage network.
What task must be performed to configure multipathing for iSCSI?
To enable vmknic-based software iSCSI multipathing, you must: • Create two VMkernel port groups and connect one uplink to each of them. Bind each VMkernel network adapter to the software iSCSI adapter. Then run a rediscovery of iSCSI targets to detect multiple paths to them.
What is iSCSI Iqn?
About the iSCSI Qualified Name (IQN) In an iSCSI network, each iSCSI element that uses the network has a unique iSCSI name and is assigned an address for access. Each iSCSI element, whether an initiator or target, is identified by a unique iSCSI Qualified Name (IQN).
What is the difference between FCoE and iSCSI?
Fibre Channel over Ethernet Like iSCSI, FCoE uses standard multipurpose Ethernet networks to connect servers with storage. Unlike iSCSI, it does not run over TCP/IP — it is its own Ethernet protocol occupying a space next to IP in the OSI model.
How does iSCSI storage work?
ISCSI works by transporting block-level data between an iSCSI initiator on a server and an iSCSI target on a storage device. The iSCSI protocol encapsulates SCSI commands and assembles the data in packets for the TCP/IP layer. Packets are sent over the network using a point-to-point connection.
What are the advantages of iSCSI?
iSCSI Benefits Efficient: As iSCSI is used for block storage, it is very fast. Reliable: Users don’t need much knowledge of the iSCSI storage system as it is very easy to understand and configure. Leverage: it is an internet-based protocol. It leverages the interoperability benefits of TCP/IP and Ethernet.
What is iSCSI How does it work?
Why would you use iSCSI?
iSCSI facilitates data transfers over intranets and to manage storage over long distances. It can be used to transmit data over local area networks (LANs), wide area networks (WANs), or the Internet and can enable location-independent data storage and retrieval.
