Dell PowerStore PowerStore T and Q Networking Guide for Storage Services

Connectivity with a Network Attached Storage (NAS) network

Network attached storage (NAS) provides:

• Front-end access such as NFS, SMB, and FTP
• Active Directory (AD) for the NAS services
• External data mobility traffic for file storage

NAS can be configured with additional features, which require some network configuration.

Identifier	Network	Requirements
	NAS	The NAS network must always be configured in an LACP bond. NOTE:The LACP bond can be configured with two or four ports on each node.

Connectivity when the NAS network is extended with a Fail-Safe Network (FSN)

PowerStore provides a Fail-Safe Network (FSN) feature for NAS configurations. The FSN feature provides a backup network for high availability when the Top-of-Rack switches have not been configured with MC-LAG.

An FSN enables the ability to configure an environment with:

• Explicit links that are designated as primary (active) and secondary (standby)
• Primary and secondary links which can have:
  • Different speeds and duplex settings
  • Ports from different I/O modules
  • More ports on the primary side than on the secondary side of the FSN

In this example, the primary and secondary networks are both configured in LACP bonds.

Identifier	Network	Requirements
	Primary	The primary network is the active network and can be configured on a single port, an LACP bond, or a combination of both. NOTE:The LACP bond can be configured with two or four ports on each node.
	Secondary	The secondary network is the standby network and can be configured on a single port, an LACP bond, or a combination of both.

Connectivity with NAS and File Import networks

Identifier	Network	Requirements
	NAS Services	Must be configured in an LACP bond. It is recommended that you configure the bond with one port from different I/O modules.
	File Import	Must be configured in an LACP bond. The LACP bond can be shared with the NAS Services bond, but cannot be shared with the Cluster bond (Bond 0).
