Introduction

Note: Data Synchronization Channel redundancy is required. NIC teaming is recommended. The heartbeat and the client interfaces have to be separated

using VLANs or different NIC ports.

Preparing Storage

Two virtual disks are required for the configuration. Both of them have to be HA devices. This document provides description of creation of the first disk only. The procedure of creation of the second one is just the same except the second device will be used for storing virtual machines so it needs to be of a sufficient size (e.g.100 Gb).

To create a disk:

1. Launch StarWind Console by clicking Start -> All Programs -> StarWind Software -> StarWind. Whenever the StarWind Console is running, its icon appears in the system tray. The StarWind Console may be accessed by double-clicking the icon using the left mouse button, or with a right- click of the mouse button and selecting Start Management Console from the pop- up menu.

2. From the Connections tree, select the computer you want to provision the iSCSI target device on and double-click it to connect.

3. Enter login and password. The default login and password are “root” and

“starwind.” You can always change them later. Also you can save the password by selecting the Save password checkbox.

4. Click OK to continue. Now when you are connected to the StarWind Service on the machine, you can create targets on it.

To create a target:

1. Click button to continue.

(5)

2. In the wizard that appears, specify a unique target name.

3. Click Next to continue.

4. Select the HA device type by clicking Hard Disk -> Advanced Virtual -> High Availability device.

5. Specify the partner server parameters. Enter server's IP address or host name, and specify the user name and password for the StarWind Service.

10. If you want to create new virtual disks, select the Create New checkbox.

(9)

12. Specify the IP address for synchronization.

13. Set node priority using the Priority box.

Note: In order to prevent data corruption in case of synchronization channel malfunction secondary node will be blocked until the synchronization channel operation is restored. You can also disable the automatic synchronization after node failure by clearing the Auto synchronization after failure checkbox.

(10)

15. Specify one of the HA device initialization methods.

17. Select the cache type, size and the expiry period in milliseconds.

(11)

18. Click the Next button to continue.
