How should we choose FCoE or iSCSI? Do you still think that fiber channel (FC) is prepared for the data center, while iSCSI is prepared for SMB? We can tell you that this idea is outdated. With the increasing LAN speed, iSCSI has been applied in many data centers. Enterprises may adopt FCoE or iSCSI for the current pro

UbuntuServer applies to many roles. In many cases, it is possible to assign multiple roles to a server. When you first install UbuntuServer, you will get a list of options, including OpenSSH, DNS, LAMP, Mail, PostgreSQL database, Print, Samba, TomcatJava, and VirtualMachine hosts. With virtualization, You can host different roles into individual Virtual Machine (VM) instances without stopping them. Ubuntu Server has many roles. In many cases, it is possible to assign multiple roles to a server.

In SAN storage systems, Lio is an efficient tool for transforming storage devices directly into available storage resources, enabling the Iscsitarget interface and CLI to create storage devices based on file/block device/ramdisk or even loopback devices. Typical scenarios and joins for accessing Iscsitarget via Iscsiinitiator as indicated:650) this.width=650; "src=" Http://s1.51cto.com/wyfs02/M00/82/FD/wKiom1dn49KzhEujAAMDcvI2nJE043.png "title=" Iscsi_ Structuer.png "alt=" Wkiom1dn49kzheujaamdcv

Yesterday, a linux system was deployed for a customer. The server itself had only GB disks as the system disk. All data is stored in network storage, and network storage (iSCSI) needs to be mounted to the local device. The configuration process is summarized as follows: Create iSCSI on Windows server 2008 R2 Due to remote deployment, I don't know what network storage is like. I asked the customer for a Wind

IET (iSCSI Enterprise Target) is a kernel-implemented iSCSI target, compared to the user-configured target (such as TGT), IET is relatively stable, and also a long history, IO directly through the kernel state, performance is better. This paper is mainly aimed at IET program architecture, from program module, command operation processing flow, initiator and target interaction, I/O process analysis.1. Progra
