When testing Oracle RAC, iSCSI is used to simulate the magnetic array (the real magnetic array requires multipath software), which is simply recorded#scsi serveryum Install SCSI-target-/srv/if=/dev/zero of=/srv/iscsi/disk01.img bs=1m count=/etc/tgt/targets.conf#backing-Store (virtual appliance) #direct-Store (actual device)-.dev.iscsi-target:iscsidisk>backing-store/srv/
Iscsi can be stored Based on raid or image storage
Image Storage: dd If =/dev/Zero of =/Zou. img bs = 1000 k count = 20000 then a 2 GB image storage disk will be generated under the root directory. Here, how to generate raid will not be mentioned first
The operating environment is On Debian. This server acts as a disk array system and has RAID (Level 5) and Image Storage Zou. IMG.

Vsphere supports storage multipath selection for NFS and iSCSI, which are explained in detail in the following two ways.first, the multipath approach to NFS is described, and NFS is a multi-path IP-based network, although he can do link aggregation through LACP, but he is only a shunt technology, not the bandwidth overlay, and the premise must be in a one-to-many, or many case, the reason is that vsphere only supports the IP hash based load balancing,

Knowledge Point Analysis:
iSCSI technology is a set of SCSI instructions that can be used by hardware devices to run at the upper level of the IP protocol, which enables the SCSI protocol to be run on an IP network to enable routing on such high speed gigabit Ethernet. iSCSI technology is a new storage technology that combines existing SCSI interfaces with Ethernet network (Ethernet) technology to enable s

Centos6.6 Mount iscsi Storage
To solve the company's backup and log problems, we have specially set up a backup server and prepared 8 TB storage space for use. Now we will mount iscsi storage on the client.
1. The client installs the iscsi installation package and starts
Yuminstall binutils iscsi-initiator-utils kmod-x
How to mount iscsi targets on centos
Few users set authentication passwords on iscsi targets. This is not safe.
You can talk about the mounting process here:
First, you need to download the Mount utility:
Yum search iscsi:
Iscsi-initiator-utils
Then install this package: yum install
Data Transfer Protocol iSCSI has become one of the industry's recognized Low-cost storage network solutions, but it is not the only solution, another transport protocol: HYPERSCSI can also provide Low-cost, Ethernet based SAN Solutions.
The HYPERSCSI protocol, first developed by the Singapore Data Storage Institute (DSI) in 2000, was designed to transmit SCSI data and instructions via raw Ethernet. It allows users to remotely use SCSI or SCSI based d
