Deploy Aruba CX 6300 switches as data center spine switches is not a best practice when positioning ArubaOS-CX switches in data center networks. The Aruba CX 6300 switches are designed for data center leaf roles, and they provide high density, low latency, and advanced features such as VSX and EVPN. The Aruba CX 83xx switches are more suitable for data center spine roles, and they provide high performance, scalability, and resiliency1.

The keepalive goes down, ISL link remains up. Switch-1 and Switch-2 remains up. The Split-recovery mode is disabled. In this case the secondary switch shutdowns SVIs is not a correct description of how the Virtual Switching Extension (VSX) fabric reacts to various component failure scenarios. VSX is a feature that provides active-active forwarding and redundancy for ArubaOS-CX switches. The ISL is the inter-switch link that connects two VSX nodes and carries data traffic. The keepalive link is a separate link that carries control traffic between two VSX nodes. The split-recovery mode is a feature that prevents split-brain scenarios when both VSX nodes lose connectivity with each other but remain up. When the keepalive goes down, but the ISL link remains up, both VSX nodes continue to forward traffic normally and do not shut down their SVIs because they can still exchange synchronization messages over the ISL link1.

Create a separate OSPF process for each VRF on Switch-1. Then redistribute each process into the other VRFs' processes is not a valid strategy for meeting this goal of enabling devices in VRF B and VRF C to reach shared resources in VRF A. This strategy would create unnecessary complexity and overhead on Switch-1, and it would not guarantee optimal routing between the VRFs. A better strategy would be to use inter-VRF routing or route leaking on Switch-1, which allows direct communication between different VRFs without requiring redistribution1.

Place all three VRFs in the same OSPF process on Switch-1 is not a valid strategy for meeting this goal of enabling devices in VRF B and VRF C to reach shared resources in VRF A. This strategy would not work because OSPF does not support multiple VRFs in the same process on ArubaOS-CX switches. Each VRF must have its own OSPF process with a unique process ID1.

Aruba Fabric Composer (AFC) with HPE StoreServ Management Console (SSMC) integration is possible. AFC is a software-defined networking solution that simplifies the management and orchestration of data center networks1. It can integrate with various data center software, such as VMware, Ansible, and Kubernetes1. SSMC is a web-based management tool that provides a unified interface for managing HPE 3PAR StoreServ storage systems2. AFC can integrate with SSMC to discover and visualize the storage network infrastructure and provide end-to-end visibility and troubleshooting1.
