We're in the process of an Oracle bare metal (ODA) to VMWare/Netapp migration project.   The netapp is an all NVME SSD SAN array.   ESX servers are dell R750s with 2 HBAs each.  We have carved up 32 "disks" (1TB each) on the netapp to present to the ESX host which are served to the linux guest via VMDK (not using RDM).   When we are running the SLOB benchmark tool, we can see the linux host making use of all 32 ASM disks (as it sees them):   But when the ESX admin looks at the disks at the ESX layer, he is only seeing 2 busy disks:   Is this normal?   Do we have some bottleneck due to how we have the disks presented to ESX?    Not sure how disks/luns from the netapp should appear on the ESX host?   Thanks   Wayne    

I'm using the free version of vSphere 6.0 (no vCenter, just vSphere Client) at home and am having some problems with usb device that is attached to the server and passed into a VM.  In the VM, the usb device periodically stops working and I have to disconnect and re-connect the device using vSphere Client.  I can do this without shutting down the VM, which is nice, but it is still somewhat of a pain through the gui interface.  Is there a way to do this via the command line rather than using the vSphere Client "Edit Settings" interface?  I installed the vSphere CLI on a windows server, but I only see references in the docs to changing the network interfaces/cdroms/floppy drives.  Not other kinds of devices. When I look at the .vmx file, the change it appears to be making when I disconnect/reconnect is: connected: usb_xhci.autoConnect.device1 = "path:2/0/3 autoclean:1" disconnected: usb_xhci.autoConnect.device1 = "" Any thoughts? thanks Wayne
