7 2 F eatures 2.1 What is iSCSI? iSCSI (internet SCSI) is a protocol that encapsulates SCSI (Small Computer System Interface) commands and data in TCP/IP packets for linking storage devices with servers over common IP infrastructures. By using iSCSI, y ou can supply high performance SANs (Storage Area Networks ) using standard IP networks like LAN,[...]

8 • Lower costs by centralizing storage management. • iSCSI also simplifies the installation and on-g oing management of a SAN versus using Fibre Channel. With Open-E iSCSI, you can add storage to your existing network quickly, easily, and most important cost-efficiently. Expensive ha rdware is no longer necessary . Take any computer, a new rac[...]

9 3 Hardware installation 3.1 Getting ready Switch off the computer, remove the power supply, and open the PC's enclosure. In tower cases, the side parts often can be re moved individually (on the backside of the enclosure you just need to remove a few screws). Many machines have U- or O shaped covers that have to be pulled off (eithe r toward[...]

10 In the package you will find an adapter cable, which pro vides Open-E iSCSI with power. The little white plug corresponds with the matching connector on Open-E iSCSI. As a final step, the adapter has to be connected to the white power-supply plug (see photo): That should conclude the installation! Be fore putting the enclosure on your computer a[...]

11 4 Configuration 4.1 The basic configuration of the iSCSI computer Connect your keyboard and a monitor to the iSCSI computer. You will only need those devices for the basic con figuration or extended maintenance configuration. You may have to change the function “Halt On: All Errors” in your PC's BIOS, so that the system starts even with[...]

12 If the network has a DHCP server, Open-E iS CSI should gain access to the IP settings automatically. If that is the case, you can proceed at 3.5. If your network does not have a DHCP server, Open-E iSCSI will st art with the default settings: IP address 192.168.0.220 and subnet mask 255.255.255.0. You can change these values again by ty ping in [...]
