Best Practices
High Availability Configuration and IP Storage
Traffic Segregation
• High Availability — Use Citrix
®
XenCenter
®
to create a network
interface bond using two NIC ports. This provides high availability for
storage traffic.
•
IP Storage Traffic Segregation — To segregate IP storage traffic, create a
new host interface. In XenCenter, click on the host and select
Management Interfaces . Create a new interface and configure the
IP settings so that the storage management interface is on a separate
subnet than the host management interface. To segregate IP storage traffic
from host management traffic, the storage interface must be on a separate
subnet than the host management interface.
NOTE: As a best practice, it is recommended to use a static IP address for the host
management and storage interface.
Scripted Backup of XenServer Host Database
To protect against unintentional configuration loss, it is recommended that
you regularly back up the XenServer host database. This operation can be
performed using XenCenter. However, it is beneficial to script a recurring
backup from your management system where XenCenter is installed.
To accomplish this, perform the following steps from your
management system:
1
Create a directory to house the backup batch file and host database
backup files. For example,
C:\backup .
2 Create a new batch file, and paste the following text into its contents:
@echo off
if "%1" == "" goto error
if "%2" == "" goto error
