  • Yeh - it’s just the Arubas are much more sensitive to slightly dodgy connections. Connections and wiring which worked with their predecessor Ciscos just fine is persona non Grata in the Aruba universe.

    With cameras they just won’t talk to them even if the port is set to 10mbps rather than Auto. Stick an unmanaged switch in the way and they work fine.

    One thing I have found is that FS.com sfp+ Aruba compatible modules work just fine which saves a packet!


  • We have an extensive Aruba estate here (managed for us by the local authority). You have to be careful about licenses for management software. The authority weren’t so there are issues… Though that may be authority incompetence rather than an Aruba issue.

    The other thing we have noticed is that they are very touchy indeed about 10mbps connections (cameras often need an intermediate unmanaged switch), and also will drop so-so 1Gbps links back to 100mbps at the drop of a hat…






  • I have a small cluster running using Starwind for my vSAN. For me it’s much cheaper than a hardware equivalent and is performant enough.

    Oh and I haven’t had a “stop work” issue with it in 8 years.

    Somewhat remarkably it was OK performance-wise when sync/iSCSI traffic were running on 1Gb copper connections to spinning rust storage… Now I have 10Gb fibre between the hosts, coupled with nvme drives, and it’s quite (comparatively) quick.

    As with all things YMMV… But vSAN is the way for my use case.








  • Temperature is not scalar

    Messers Rankine, Kelvin and even Fahrenheit would beg to differ… Temperature is scalar, however it’s effects on living things is generally not mostly owing to chemistry.

    The claim that a 40° C jump in Sub-Zero temperatures is tolerable, but wouldn’t be in the UK or whatever they’re saying in this article… That’s nonsense

    Au contraire my dear fellow. For a human, the article is entirely correct. A rise of 40° C in a particularly cold place is indeed tolerable for a human. A similar rise in, say, the UK today would put the temperature at 52° C - hotter than Death Valley on a well above average day and considerably less tolerable.

    Of course a single recorded rise in temperature isn’t a good indication of climate…
