Reducing power usage part 2

Since posting part 1 of reducing power, I received the order of my ASRock and have re-used the hard drives from the previous Shuttle I had. The Shuttle wasn’t loud by any stretch, but the ASRock is incredibly quiet. To the point where I have to check it’s still running!

After previously being impressed with how long my hard drives have lasted, one went pop during a power failure. That’s a bit disappointing, but the drives are only Western Digital Blue’s which are just generic consumer desktop disks.

Reducing power usage part 1

A good 7 years ago, I bought a Shuttle SX38P2 Pro which has been running pretty much 24/7 ever since. Recently the PSU fan has been struggling, but I can’t complain for the time it’s been in use. Over those 7ish years I’ve suffered a single drive failure.

# smartctl -a /dev/ada0 | grep Power_On_Hours
9 Power_On_Hours 0x0032 081 081 000 Old_age Always - 13972
# smartctl -a /dev/ada1 | grep Power_On_Hours
9 Power_On_Hours 0x0032 015 015 000 Old_age Always - 62738

As the fan was struggling, I contacted Shuttle to ask about replacements but received no reply. That was disappointing, but I guess understandable as the model has been discontinued (I didn’t think the cooling was model-specific though).

vSphere 6.7 Upgrade – PSC’s

I’ve recently upgraded our environment from vSphere 6.0 (shush, it’s still in support until March 2020). Fairly standard setup really, a couple of vCenter’s, a couple of PSC’s (to allow ELM), and several hosts. We also ran the HTML 5 Fling as nobody wants to use that god-awful web client which was forced on us for some reason. Yes, it’s been years. No, I’m not over it.

I won’t go in to how to perform the upgrade, that’s well documented and often repeated already, I’ll just point out a couple of things I noticed.
