    Here's one for you. Say I had a few hundred hosts, how many could I stage to at once? All in the one datacenter, not clustered, on the same vCenter and Update Manager

    what exactly are you asking mate?
    stage to? patches? vms? what are you wanting to stage to the hosts?
    this is dependent on a lot of factors

    Ah sorry mate, stage ESX patches to the Hosts ready for remediation. The patches are stored in a folder on my Update Manager server, so I'm wondering if I tell 300 hosts to stage their patches, if its all going to go pete tong.

    I've got a datacenter in vSphere with 300 stand alone hosts. No folders, just the one datacenter.

    ** Edit: Sorry I don't mean to come across as dense here. I know a lot is dependant on LAN/WAN speeds etc. But I'm wondering if vCenter will queue these up, do some clever BITS type calculations or if its just going to immediately thrash the disks on my Update Manager server making it highly likely to fall over.

    I've got the following error on a number of Hosts: TSC: 631030280 cpu0:0)NUMA:827 : Significant imbalance between NUMA nodes detected. Performance may be impacted.

    I know what it means, that the RAM in my boxes isn't evenly distributed on each memory bank per CPU. It's no big deal and means if a CPU needs to access RAM on the other bank it will be approx 1ms slower then if it was on its own bank.

    My questions are..... I iLO onto a Host. I can see the red message. I'm not concerned BUT

    1) what would happen if I get a second error that I do have to act upon? Will it put it beneath this first message? Overwrite that message? Not display the other message :S

    2) is there a way to acknowledge this error on the host? I know I can view errors here /var/log/vmkwarning log

    Cheers
