Iscsi Initiator For Macos


In an iSCSI SAN, an initiator is needed on each computer that requires access to the networked storage. An initiator is not included with the purchase of a Mac, so we created globalSAN to bring iSCSI to your Mac.


I am still looking for a solution, but meanwhile I gave up with Kernsave -iscsi-initiator.aspx and the above mentioned OpenSource Initiator. Kernsave works nice while you are using it. Also the limitation to only one connection would be not a problem. It's more the fact that you can't create a setup where the connection is done automatic to ensure Time Machine find the volume.


KernSafe iSCSI Initiator X is an iSCSI initiator software for Apple Mac OS X (Free license available). With the benefits of iSCSI technology, iSCSI initiator X can export an SAN device to local Mac OS X machine include: Mac Pro, iMac, Mac Server, Mac Mini and even MacBook Pro.It is very useful software in visualization industry and data centralization for small business and large enterprise.

The protocol allows clients (called initiators) to send SCSI commands (CDBs) to storage devices (targets) on remote servers. It is a storage area network (SAN) protocol, allowing organizations to consolidate storage into storage arrays while providing clients (such as database and web servers) with the illusion of locally attached SCSI disks.[1] It mainly competes with Fibre Channel, but unlike traditional Fibre Channel which usually requires dedicated cabling,[a] iSCSI can be run over long distances using existing network infrastructure.[2] iSCSI was pioneered by IBM and Cisco in 1998 and submitted as a draft standard in March 2000.[3]


An initiator functions as an iSCSI client. An initiator typically serves the same purpose to a computer as a SCSI bus adapter would, except that, instead of physically cabling SCSI devices (like hard drives and tape changers), an iSCSI initiator sends SCSI commands over an IP network. An initiator falls into two broad types:


A software initiator uses code to implement iSCSI. Typically, this happens in a kernel-resident device driver that uses the existing network card (NIC) and network stack to emulate SCSI devices for a computer by speaking the iSCSI protocol. Software initiators are available for most popular operating systems and are the most common method of deploying iSCSI.


A hardware initiator uses dedicated hardware, typically in combination with firmware running on that hardware, to implement iSCSI. A hardware initiator mitigates the overhead of iSCSI and TCP processing and Ethernet interrupts, and therefore may improve the performance of servers that use iSCSI.An iSCSI host bus adapter (more commonly, HBA) implements a hardware initiator. A typical HBA is packaged as a combination of a Gigabit (or 10 Gigabit) Ethernet network interface controller, some kind of TCP/IP offload engine (TOE) technology and a SCSI bus adapter, which is how it appears to the operating system.An iSCSI HBA can include PCI option ROM to allow booting from an iSCSI SAN.


An iSCSI offload engine, or iSOE card, offers an alternative to a full iSCSI HBA. An iSOE "offloads" the iSCSI initiator operations for this particular network interface from the host processor, freeing up CPU cycles for the main host applications. iSCSI HBAs or iSOEs are used when the additional performance enhancement justifies the additional expense of using an HBA for iSCSI,[4] rather than using a software-based iSCSI client (initiator). iSOE may be implemented with additional services such as TCP offload engine (TOE) to further reduce host server CPU usage.
