You must have the NCM or SCM plugin installed on your ESXi hosts to be able to use IP Address Zones, and use the HPE Nimble Storage path selection policy (NIMBLE_PSP_DIRECTED). Using NCM (Nimble Connection Manager) and SCM (Storage Connection Manager) on your VMware ESXi hosts, the HPE Nimble and HPE Alletra storage solution can intelligently choose when to use the interlink depending on paths available, and the current health of SAN connectivity. However, in the event of a switch, NIC, and/or path failure, we do want to have the interlink available to facilitate data access and be available when required. When you have SAN switches that include an ISL (inter-switch link) that are connected to an HPE Nimble or HPE Alletra SAN, it’s preferred not to have traffic go across that interlink, as it creates additional hops for packets, as well as increases latency. He then researched it, and confirmed we should have it enabled and configured. I actually had to advise the technician that numerous HPE technical documents recommended to enable and configure it when you have an ISL. Even though the customer purchased HPE Technical Installation and Startup Services, the HPE installer was not aware of IP Address Zoning and it’s purpose, advising us to disable it. I recently had a customer that purchased and deployed two HPE Alletra 6010 SANs for their VMware environment, where I was contracted to implement these SANs.
