iscsi multipath

Overview I have always strongly recommended ZFS because it is so easy to use. However, it can only run on Oracle's Solaris and FreeBSD systems until now. To share it with other systems, you can only use NAS or SAN. The NAS method is very simple. I have been using Samba for implementation. Of course NFS is also acceptable. I haven't tried SAN before. Of course SAN is better to use, and the network speed is fast enough now. Although NAS and SAN are both external storage for storage, but for the cl

Learn how to implement the Internet small computer system interface (iSCSI) on Aix ). This step-by-step process describes how to achieve iSCSI on an AIX host through Cisco MDS across the storage area network (SAN. These procedures also describe some interface optimization parameters.

SAN is short for the storage area network. In the early days, san used fiber channel technology. Later, when the iscsi protocol appeared, to distinguish the two, the ip san and fc san are divided. Because of its high price, fc san has caused many enterprises to leave their homes. As a good replacement product, ip san has become a reality. Currently, most storage devices support TOE-based interfaces and can process TCP/IP protocols based on hardware. T

ISCSINetworked Storage ServicesFirst, Theoretical PartISCSI the conceptISCSI, or internetscsi, is a standard developed by the IETF for mapping SCSI blocks to Ethernet packets. Fundamentally, it is a new kind of storage technology based on IP Storage theory, which combines SCSI interface technology and IP network technology which is widely used in storage industry , and can be built on IP network. SAN. To put it simply,ISCSI is a networked storage te

iSCSI is mainly through TCP/IP technology, the storage device side through the iSCSI Target (iSCSI targets) function, to provide the server side of the disk, and then through the iSCSI Initiator (iSCSI initialization user) function,To be able to mount the client using

I. iSCSI Introduction Internet small computer system interface is an opportunity TCP/IP protocol, used to simulate SCSI high-performance local storage bus through an IP network, so as to provide data transmission and management for remote storage devices. As the San protocol, iSCSI expands the San across local and wide area networks, and provides location-independent data storage and retrieval through distr

VMware connects to shared storage in three different ways, San,ip sans (that is, iSCSI) and Nas (NFS). This article is not about the difference between the 3 and the SAN and NAS, please go to Google. Second, this article does not look at FC Sans, if your environment already has a SAN that supports MPIO and has enough storage space, try to make the most of it. Because many articles point out that Nas/nfs is an ideal medium for low I/O demand workloads
