Target host and directory

Home > Storage > PowerScale (Isilon) > Product Documentation > Data Protection > Dell PowerScale SyncIQ: Architecture, Configuration, and Considerations > Target host and directory

Target host and directory

  • In the Target Host field, specify the IP address or fully qualified domain name of the target cluster. Ensure that the DNS hosts specified on the source cluster can resolve the FQDN of the target cluster.

    In the Target Directory field, specify the directory where data from the source cluster is replicated. As stated above, it is recommended to consider the Access Zones best practices as the location of the target directory eases failover and failback operations in the future.

    Target cluster SmartConnect zones

    When a policy target cluster name or address is specified, a SmartConnect DNS zone name is used instead of an IP address or a DNS name of a specific node. An administrator may choose to restrict the connection to nodes in the SmartConnect zone, ensuring the replication job will only connect with the target cluster nodes assigned to that zone. During the initial part of a replication job, SyncIQ on the source cluster establishes an initial connection with the target cluster using SmartConnect. After a connection with the target cluster is established, the target cluster replies with a set of target IP addresses assigned to nodes restricted to that SmartConnect zone. SyncIQ on the source cluster will use this list of target cluster IP addresses to connect local replication workers with remote workers on the target cluster.

    To use target cluster SmartConnect zones, perform the following steps:

    1. On the target cluster, create a SmartConnect zone using the cluster networking WebUI.
    2. Add only those nodes that will be used for SyncIQ to the newly created zone.
    3. On the source cluster, SyncIQ replication jobs (or global settings) specify the SmartConnect zone name as the target server name.

    Note: SyncIQ requires a static allocation method of IP addresses and does not support SmartConnect Dynamic Allocation Method of IP address pools. If Dynamic Allocation IPs are specified, the replication job will fail with an error message in the log file and trigger an alert.

    The same option is also available as a global SyncIQ setting, under Data Protection > SyncIQ and selecting the Settings tab. While SmartConnect node restriction settings are available per SyncIQ policy, often it is more useful to set them globally. Those settings will be applied by default to new policies unless they are overridden on a per-policy basis. However, changing these global settings will not affect existing policies.

    Note: As stated in SyncIQ policy requirement for System Access Zone, SyncIQ data replication is only supported through the System Access Zone because SyncIQ is not zone-aware. If a new SyncIQ policy is created or an existing policy is edited, an error is displayed if it is not configured for the System Access Zone. This zone requirement applies to both the source and target clusters.
