After a routine update of a 6-node Nutanix cluster, a Nutanix Cluster Check (NCC) warning popped up indicating a problem with the SAS cabling. Running the check on the CLI offered some more details. Running : health_checks hardware_checks disk_checks hpe_hba_cabling_check [==================================================] 100% /health_checks/hardware_checks/disk_checks/hpe_hba_cabling_check [ WARN ] -----------------------------------------------------------------------------------------------------------------------------------------------------------+ Detailed information for hpe_hba_cabling_check: Node 10.99.1.205: WARN: Disk cabling for disk(s) S6GLNG0T610113 are detected at incorrect location(s) 3:251:8 respectively where each value in the location corresponds to box:bay Node 10.

There’s a world below clouds and enterprise environments with thousands of VMs and hundered or thousands of hosts. A world that consists of maximal three hosts. I’m working with quite a few customers, that are using VMware vSphere Essentials Plus. Those environments consist typically of two or three hosts and something between 10 and 100 VMs. Just to mention it: I don’t have any VMware vSphere Essentials customer. I can’t see any benefit for buying these license.

Nutanix was founded in 2009 and left the stealth mode in 2011. Their Virtual Computing Platform combines storage and computing resources in a building block scheme. Each appliance consists up to four nodes and local storage (SSD and rotating rust). At least three nodes are necessary to form a cluster. If you need more storage or compute resources, you can add more appliances, and thus nodes, to the cluster (scale out).
