When installing a new Isilon cluster, the Configuration Wizard has not changed. It still prompts you for int-a, int-b, and failover range. All configuration and setup steps will be the same regardless of InfiniBand or Ethernet option selected.
The following figures show the relative positioning of back-end ports provided in the Compute Assembly for each Dell PowerScale/Isilon platform node type.
The following table provides configuration information for the back-end ports in PowerScale platforms:
Setting | Description |
Int-a network setting | The network settings used by the int-a network. The int-a network is used for communication between nodes. |
Netmask | The int-a network must be configured with IPv4. |
IP range | The int-a network must be on a separate or distinct subnet from an int-b/failover network. |
Int-b and failover network setting | The network settings used by the optional int-b/failover network. |
Netmask | The int-b network is used for communication between nodes and provides redundancy with the int-a network. |
IP range | The int-b network must be configured with IPv4. |
Failover IP range | The int-a, int-b, and failover networks must be on separate or distinct subnets. |
The monitoring capabilities on PowerScale/Isilon back-end switches correspond to the field replaceable unit (FRU) components such as power supply, the fan, or others. Protocol and performance monitoring capability is not provided.
Note: Customers should not attempt to alter the back-end network configurations provided by Dell. Any attempt to do so can result in a cluster-wide outage.
For SNMP capabilities, a customer may send an SNMP alert through the CELOG system. In today’s back-end Ethernet world, we no longer have opensm topology files to view all connected devices on the back-end network. If you want to know what is connected to the fabric of back-end Ethernet (int-a or int-b), you can use the isi_dump_fabric int-a (or int-b) command.
