Disclosed are systems, methods, and computer-readable media for assuring tenant forwarding in a network environment. Network assurance can be determined in layer 1, layer 2 and layer 3 of the networked environment including, internal-internal (e.g., inter-fabric) forwarding and internal-external (e.g., outside the fabric) forwarding in the networked environment. The network assurance can be performed using logical configurations, software configurations and/or hardware configurations

Detection of overlapping subnets in a network

A response communication that includes one or more data packets is received at a broker associated with a storage node of a plurality of storage nodes via a virtual network associated with the plurality of storage nodes of a storage system. The one or more data packets are provided, via the virtual network associated with the storage nodes, to a tenant communication component associated with an intended destination. A connection between the broker and the tenant communication component associated with the intended destination is terminated. A new connection between the intended destination and the tenant communication component associated with the intended destination is established. The new connection is associated with a virtual network associated with a storage tenant. The one or more data packets are sent to the intended destination via the virtual network associated with the storage tenant.

Secure communications of storage tenants that share a storage cluster system

One or more data packets at a storage node of a storage cluster system is received via a virtual network associated with a storage tenant. A connection between the storage tenant and a tenant communication component of the storage cluster system is terminated. A new connection is established between the tenant communication component of the storage cluster system and a destination associated with the one or more data packets. The one or more data packets are provided to the destination associated with the one or more data packets using a virtual network associated with storage nodes of the storage cluster system.

A request to perform a storage operation for a storage system is received. It is determined that the requested storage operation is associated with a policy that requires a quorum of approvals before being allowed to be performed. It is determined whether the quorum of approvals has been obtained. In response to a determination that the quorum of approvals has been obtained, a command to perform the requested operation is provided to the storage system.

Quorum in a distributed system

Disclosed are systems, methods, and computer-readable media for assuring tenant forwarding in a network environment. Network assurance can be determined in layer 1, layer 2 and layer 3 of the networked environment including, internal-internal (e.g., inter-fabric) forwarding and internal-external (e.g., outside the fabric) forwarding in the networked environment. The network assurance can be performed using logical configurations, software configurations and/or hardware configurations.

A first set of one or more tenant communication components are configured to communicate with a first separate system component of a first storage tenant via a first virtual network. A second set of one or more tenant communication components are configured to communicate with a second separate system component of a second storage tenant via a second virtual network. The second virtual network is separate from the first virtual network. A plurality of tenant communication components of the storage cluster system including the first set of one or more tenant communication components and the second set of one or more tenant communication components are configured to communicate internally in the storage cluster system via a third virtual network separate from the first virtual network and the second virtual network.

Validation of layer 3 bridge domain subnets in a network

Disclosed are systems, methods, and computer-readable media for assuring tenant forwarding in a network environment. Network assurance can be determined in layer, layerand layerof the networked environment including, internal-internal (e.g., inter-fabric) forwarding and internal-external (e.g., outside the fabric) forwarding in the networked environment. The network assurance can be performed using logical configurations, software configurations and/or hardware configurations.

Event generation in response to validation between logical level and hardware level

Validation of layer 3 bridge domain subnets in in a network

An optimized interface for handling routed and non-routed point-to-point sessions is provided. According to one exemplary aspect, when a PPP session is established for a client, an interface data structure or module is dynamically created for the client corresponding to the PPP session. The interface data structure includes, for example, Layer-2 and Layer-3 information relating to the PPP session. Upon its creation, the interface data structure is linked to the optimized interface. The created interface data structure is then used by the optimized interface to facilitate communications with the client for the duration of the PPP session.
