ESXi / vSAN Command to show either disk speed such as 12gbps or the disk type such as SATA

MJMSRI — Wed, 21 Sep 2022 16:00:39 GMT

Hello, we have a 19-Node vSAN Cluster with 433 Disks.

I want to ensure that all disks are SSD SAS Disks running at 12 Gbps and that there are not any SATA disks running at 6 Gbps.

is there a command to show the disk speed for all of these 433 disks?

Thanks

@MJMSRI, As far as I am aware, ESXi can only report this for devices attached to that node only but you could of course just use the same esxcli command via PowerCLI to all nodes - if you run 'esxcli storage core device list' it lists the devices attached and lists the 'Device Max Queue Depth' - this will be 32 for SATA devices and higher for SAS (whether this will be 64, 128 or 256 depends on the device firmware and optimisations made by vendor):
