comment Puppet: Pass facter value to class (sensu puppet module)
Agreed, you have some strange quoting going on. Remove the single quotes around the double quotes around fqdn.

comment Practical difference between SPARC vs x86
That Sparc T5 runs 128 threads /per socket/ (where x86 would be maybe 40 if you went big), and you can get 8-way systems. That's a crazy number of simultaneous jobs [numbers courtesy en.wikipedia.org/wiki/SPARC_T5 ]. Will your software run on it? Maybe.

comment Nginx - 2 https servers on same public ip
You'll need a public IP per certificate if you need to support XP (which doesn't support SNI)

comment What would be better for fast search Lucene.Net or Redis
Why can't you just make that field unique? Adding a second system (effectively a cache) adds a ton of other problems. What don't we know about the requirements here?

comment How to backup a full Centos Server?
Dump is a literal copy of the filesystem, with everything in there. As long as you don't have more than one (check by running mount) that's all you need.

comment Resetting to factory default on a Gigamon GigaVUE-212
The support answer is that I need to provide a statement from the original owner saying they've sold it to me, along with some money for a new warranty. Geez.

comment How do storage IOPS change in response to disk capacity?
There could be some improvement due to increasing platters in a drive, or increasing platter density (less movement per byte), but I doubt it's huge.

comment Send email from main domain using exim4
Could you include your configuration? An Exim expert will likely know some things to try without it, but can say for sure if they can see your full configuration.

comment PHP-FPM user permissions after restart
Welcome to ServerFault! If you found a solution to your problem (and it looks like you did), you should post it as an answer instead of a comment. That way people finding this later will see that there's a solution.

That's a great answer! It would have done what I was looking for.

comment XenServer 6.2 changing mtu
:D Glad to help. A while ago Xen didn't support jumbo frames at all, so I actually came to tell you you were SOL, but things evidently changed.

It depends, sadly.

Maybe ask GCE support? This seems like the sort of thing they could answer quickly.

comment Is there a way to read SMART attributes for drives in a SAN?
Page 238 of the owner's manual (ftp.dell.com/Manuals/Common/…) says "The RAID controller monitors all attached drives and notifies users when a predicted failure is reported by a physical disk. "

comment Is there a way to read SMART attributes for drives in a SAN?
Your vendor, if they're doing their job, is watching for that same reason :) NetApp (for example) will ship drives to replace drives in a pre-fail state.

comment Progressive video download in a classroom environment - how to determine bandwidth needed
There's no prioritization done without your configuration, so each stream would get roughly equal slices of the bandwidth. I don't know what you would google exactly, it's a characteristic of a shared network.

comment Brocade mirror ports
I think that fibre channel switches are a bit different than ethernet. tcpdump probably won't work for FC traffic, for instance, and I don't know if it would even listen on that kind of card (since it doesn't look like a NIC).

comment how much openvz burstable memory can be used
It's super cheap. Sometimes you care about that more than performance :)
