comment Linux - Is there a way to prevent/protect a file from being deleted even by root?
God, Root, what is difference?

comment Is it possible to detach and reattach a ZFS disk without requiring a full resilver?
Can you operate a second server onsite (or even a 2nd ZFS array in the same server)? Put your hotswap bays in it, sync between it and the main one, and then rotate the entire backup ZFS array in/out of the server as a unit.

comment What is a reasonable maintenance schedule for Windows PCs?
25 computers with 3 OS versions suggests adhoc computer procurement. I suspect Loopo probably has a mess of different computer models and would end up having to create almost as many clean images as individual computers. Under those conditions prepping images for all the existing machines in advance seems like a lot of work that will mostly go unused. Save clean images for any new systems or old ones that need fresh installs; beyond that is probably more time than it's worth for non mission critical machines.

comment What is a T1 in modern terms?
@HopelessN00b about a dozen years ago an acquaintance of mine had a t1 for his home internet. He worked for a small ISP/Hosting company and somehow convinced his boss to let him use their spare/backup t1 as his home connection. I'm not sure, but I think the hardware was still in the office and he was using a spare point to point wireless link of some sort to get the signal to where he lived.

comment Why do we still use power supplies on datacenter servers?
Assuming we ever get an all DC solution, there's a good chance that 3.3v won't be part of it. The existence of molex-sata adapters has precluded any widespread use of 3.3v by disk drives; and the last major component on mobos that operated at 3.3v (legacy PCI) is increasingly unused on modern systems.

comment Why do we still use power supplies on datacenter servers?
Most simple (single socket, small number of disk drive, no discrete GPU - for compute) servers could be powered off a picoPSU (small board that plugs into an 24 pin ATX connector that takes 12V and produces a few amps of 3.3/5V power for misc components) like is used in a number of DIY minibox PCs. mini-box.com/DC-DC

comment How do services with large ingest rates install enough hard disks fast enough?
@mindthemonkey that's done in the same factory using the same cheap Chinese labor that ordinary rack mounted servers/blades used by the rest of us are assembled in.

comment Two NIC card with same mac address
While sending a nastygram to the vendor is certainly justified, don't most NICs allow you to change the default MAC so that if you have any configuration dependent on it when you replace a card/server you only need to make the change in one place?

comment I have a 3.46 TB Raid disk array, but when I setup windows server 2012, it only refers to it as 2TB
@mfinni the archaic definition of "inspiring fear" needs to be resurrected to the mainstream.

@voretaq7 good point about how often wifi practice falls well short of theory.

comment Our wi-fi at work is ridiculously slow, will adding more range extenders improve it?
@BlueRaja IIRC 802.11ac allows a router with multiple spacial streams to either combine them all to give a single client a faster connection (like in previous versions), or to connect each stream to a separate client allowing several to be transmitting concurrently.

@DavidSchwartz Are OpenWRT, etc. based devices really the right choice for building a medium/large size network? While they're better than basic consumer firmware if you're putting a bunch of them together in a single network wouldn't something more enterprise oriented with a central admin feature (vs having to log into each one separately to configure it) be a better choice?

comment Are SSD drives as reliable as mechanical drives (2013)?
@MisterSmith even high end desktop SSDs are cheaper per GB than ones targeted at typical data center uses. In addition to more powerful controllers in some instances (or just low volume firmware tuned for throughput instead of burst performance), they get the best flash skimmed off the top of the production run because many server workloads are orders of magnitude more IO intensive than desktop drives and would quickly kill a consumer drive.
