iSCSI Internet SCSIiSCSI, short for Internet SCSI enables any machine on an IP network (initiator) to contact a remote dedicated server (target) and perform block I/O on it just as it would do with a local hard disk. Here are a few key terms related to iSCSI to help you make the best of your iSCSI storage capabilities. iSCSI Target Implementation can create iSCSI targets on any Linux system which can be accessed from the iSCSI initiator. A system making iSCSI targets available requires partition to export. Note you can implement iSCSI Targets without the need of a SCSI disk. Also, an iSCSI device may execute a command from an iSCSI initiator to perform some task. The iSCSI target is usually an iSCSI storage device but the host adapter can also be a target. SAN [Storage Area Network]- A high performance network or sub network designed to connect storage elements and the back end of the servers. A typical application of SAN is network data storage. Linux-iSCSI refers to the Linux operating system widely used on the Internet. The Linux iSCSI driver acts as an iSCSI protocol initiator to transport SCSI responses over an IP network between the client and an iSCSI-enabled device. For more information, read about iSCSI protocol. iSCSI protocol is based on TCP/IP for data transfer. Critics of iSCSI expect worse between client and storage. However new iSCSI techniques like TCP Offload Engine (TOE) help enhance the data transfer. Tests show excellent performance of iSCSI SANs, whether TOEs or plain Gigabit Ethernet NICs were used. iSCSI performance until recently was a subject for debate - is iSCSI performance a viable option for large organizations. Today, iSCSI performance has improved to the point where large organizations deploy Gigabit and 10 Gigabit iSCSI networks. iSCSI Array iSCSI Array is a group of hard drives that communicates with a computer as if it was just one drive. Free iSCSI Ware free iSCSI ware is widely available on the internet and companies offering free iSCSI ware to try before you buy. iSCSI Products Here are some popular types of iSCSI Products to upgrade your computer's iSCSI performance. 2 Port Ultra SCSI PCI Cards SCSI Controller Card, PCI External SCSI III Cable |
