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 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.
Adjusting SCSI Timeouts to Tolerate Storage
Controller Failures
To account for time that an I/O may take to complete in a case where the
Dell PowerVault MD3000 or the PowerVault MD3000i storage array goes
through exception recovery on I/O operations, it is recommended to adjust
the SCSI timeouts on XenServer hosts and VMs that are resident on the SRs
on the PowerVault MD3000 or the PowerVault MD3000i storage arrays.
