comment FBWC and Zero Memory (ZM) RAID Controller on HP DL360p
The only reason I can see to use the zero-mem-option would be for booting very static OS's such as ESXi. Otherwise spot-on.

Plus they'd have to buy HP disk caddies too of course.

comment hp proliant not recognizing emc sas drives
@sivann I don't care whether this server is for testing (which you didn't mention anyway) - this site is for people looking to build supportable systems, not hacks

comment SCSI queue depth / command queue settings
You don't mention an operating system for these servers - if you're using ESXi I think you may have exceeded the max-paths (depending on version) which could cause exactly that kind of issue. Come back to us with more details please.

comment VMware Guest machine NIC errors
Everything's all so old - essentially it's unsupported and this site is for supported/supportable solutions.

Firstly you should be using vmxnet not pcnet32, secondly it's 2015 what are you doing with 5.11-32bit!!!?! you also don't mention which version of ESXi you're running either but I'm pretty sure your issues are these, the drive one in particular, you should be running the latest vmtools.

comment Mixing HBAs in a failover cluster?
Either/both - I'm old enough to remember several situations where a driver has caused some form of outage, splitting this risk is usually a good idea.

comment Missing memory on ESXI 6.0
That's just not right though, I looked at one of my hosts and I was losing hundreds of MB not GBs and this is on a host with 768GB of RAM, it's definitely not right.

comment Missing memory on ESXI 6.0
One word of gentle warning luri - serverfault is a site for professional sysadmins who like to build and run supportable systems in a pro-environment. I'm thinking this looks like a laptop you're running on right? in which case perhaps in the future you could consider asking questions about dev/test setups like this on our sister site superuser.com as they cater better for this kind of system ok.

comment Missing memory on ESXI 6.0
I ****ing HATE resource pools, for 99% of users there's little benefit of using them and they can create a few pitfalls. Get rid of them and see how you get on.

comment Missing memory on ESXI 6.0
No not at all, that's still very odd, I wouldn't expect anything like that much memory to be used by the kernel. It looks like your server's very far from the HCL specs (I think) - I'm hoping that's got nothing to do with it.

comment NVMe speed degradation after kernel upgrade
Is Centos 7.1 with a 4.2.5/4.3 kernel supported by Centos? Serverfault is for professional sysadmins keen to run supportable platforms, perhaps superuser.com might be more appropriate for more 'experimental' scenarios
