About support for Nutanix segmented iSCSI network
NetBackup support separating backup traffic with a use of Nutanix iSCSI segmented network. Separating backup traffic is helpful to reduce load on production resources, dedicating right size resources for better backup-recovery speed and security. By default, backup-recovery traffic flows over Nutanix cluster management network using iSCSI data services IP for initial connection and discovery.
During AHV cluster configuration, choose one of the following options for iSCSI transport:
Use iSCSI data service IP
Use segmented iSCSI data service IP
Use specified segmented iSCSI data service IP
For more details See Add or browse an AHV cluster.
The iSCSI segmented network is on different subnet than the cluster management network, so backup host network must be configured to connect to:
AHV cluster-management network
iSCSI-segmented network.
To achieve this, configure the backup host with two VLANs. One corresponding to cluster management network and other corresponding to segmented iSCSI network planned to use for backup-recovery traffic.
For better performance, use hostname/IP corresponding to segmented network as hostname while installing/configuring NetBackup on the backup host.
Validate connectivity using the following command on Windows host:
Click This opens iSCSI initiator properties dialog.
Click and provide the IP address as per configured iSCSI Target Type for the AHV cluster.
DEFAULT: iSCSI Data services IP from cluster details page
SEGMENTED: segmented iSCSI Data from cluster details page
SEGMENTED_SPECIFIC: Virtual IP specified while configuring cluster in NetBackup.
Validate connectivity using following command on linux host:
iscsiadm -m discovery -t sendtargets -p correct IP as per configured iSCSITargetType
DEFAULT: iSCSI Data services IP from cluster details page
SEGMENTED: segmented iSCSI Data from cluster details page
SEGMENTED_SPECIFIC: Virtual IP specified while configuring cluster in NetBackup. If there is connectivity problem it shows an error, for example:
iscsiadm: connect to <IP> timed out
