Dell DX Object Storage – File Gateway Architectural Reference

Network

For a failover CFS configuration, the iSCSI storage can be on its own switch isolated from the DX

Storage Cluster or it can be attached to the DX Cluster network. In cases where iSCSI storage is

attached to the DX Cluster network, then ports 2 thru 5 can be shared between the iSCSI storage and

DX Storage Cluster. In this configuration, it is recommended to configure network ports for adaptive

load balancing. Sites that have suitable competence may prefer configuration and management of link

aggregation control protocol in place of adaptive load balancing.

The preferred failover network configuration is identical to that shown for a single-server CFS

configuration (above), except that iSCSI traffic will share the four NIC ports that go to the private DX

Storage network. If a site wishes to use pre-existing iSCSI storage that is available on its own VLAN,

then the recommended network port allocation is:



Connect NIC ports 0 and 1 to the CIFS/NFS network.



Connect NIC ports 2 and 3 to the DX Storage Cluster network.



Connect NIC ports 4 and 5 to the iSCSI Storage network.

Gateway Protocols

The CFS can be configured for NFS or SMB/CIFS gateways. For SMB/CIFS, users and groups can access

the system through standalone authentication, or if Active Directory Services exists, users and groups

can be authenticated through the existing ADS structure. For NFS, Dell supports version 3 only; it does

not support version 4.
