Slashdot Mirror
Among Servers, Apple's Mac Mini Quietly Gains Ground
Nerval's Lobster writes "In 2005, the first business to offer colocated Mac Minis inside a data center made its debut, provoking criticism on Slashdot of everything from how the Mini was cooled to the underlying business model. But nowadays, more than half a dozen facilities are either hosting their own Mac Minis for rent, or offering colocation services for individual consumers and businesses. While some vendors declined to give out reliability information, those who did claimed a surprisingly small number of failures. 'If Dell makes a small little machine, you don't know that they'll be making that, in that form factor, six months down the road, or what they're going to do, or how they're going to refresh it,' Jon Schwenn, a network engineer for CyberLynk Networks (which owns Macminivault) said in an interview. 'We've had three model years of Minis that have stayed externally, physically identical.' Customers are using Minis for all sorts of things: providing Mail, iCal, and the Websites for small businesses; databases, like Filemaker or Daylite; as a VPN server for those who want an IP address in the United States; build servers for Xcode; and general personal servers for Plex media streaming and other fun projects. Some are even using it for Windows."

I guess the moral of the story is "beauty is only skin deep".

just changs things.
HAHAHA. NO I kid. Apple changes thing without notice all the time.
The Kruger Dunning explains most post on
Is this a new fad or something? Some tweaker rolled into my office wanting to know if we did consulting for setting up a webserver on an apple platform. We only did windows/linux. I questioned him on why he wouldnt just use a linux box for webhosting? He didnt have an answer.
Is this just some hipster fad? Finding a use for old Apple boxes? Or do they offer something that linux/windows hosting doesn't?
These are great little machines. I have had two and want another. Oh, and I am agnostic when it comes to these things, but I do give credit where credit is due.
Even the "server" version of the Mac Mini does not support ECC RAM. Many other important server-grade features, such as IPMI, are also missing. Why would anyone choose this over cheaper, more robust commodity PC server hardware? You can't even plead cosmetics, because it's a freaking server; it goes in a rack somewhere and only a handful of IT staff ever need to see it. The only possible reason I can think of why someone would want to run an OSX server is if they were going to be remote-accessing it to run Xcode for iOS development. What else can you do on OSX that you can't do on Windows or Linux?
"more than half a dozen facilities" -> More than 6? Wow!
"have stayed externally, physically identical" -> Amazing! I wish there was a standard for servers, so that I wouldn't have to keep reconfiguring my data center layout.

"If Dell makes a small little machine, you don't know that they'll be making that, in that form factor, six months down the road, or what they're going to do, or how they're going to refresh it,"
Actually, with Dell you have a pretty good idea. They have defined life cycles for their servers, and they are pretty good about maintaining a general class of equipment. This is not the case for their low end consumer stuff necessarily, but the stuff you'd put in a datacenter.
Apple? Shit son, they'll change tack and tell nobody before hand. The Xserve is the best example. Their 1U server, a thing they sold for use in everything including super-computer like clusters. Then, suddenly it is gone. Just can't buy it anymore, no replacement. You need 1U equipment? Fuck you.
Or the Mac Pro, which is on sale, but they let get woefully out of date before updating.
Apple is the ultimate at doing whatever they want new whenever they want it. They are not at all interested in backward compatibility or consistency. They'll stick with a form as long as it suits them and then change.
Now that's fine, I'm not saying it isn't valid, however to act like they are good at stability for datacenters is silly. They are not at all. The next Mac mini could be a totally different form factor, or there could be NO next Mac mini. You don't know and Apple won't release any roadmap.
Heck a funny mini related incident is one of our professors does research with rovers he builds. They use Mac minis as their core controller because he's a Mac guy. They worked fine since they were small, and powered by DC they could hook up to the power supply for everything else. What's that you say? They aren't DC powered? Ahh yes, well a couple generations ago Apple changed it, stuck the PSU inside the unit. Great for consumers, bad for him. He's now stockpiled some older ones to use when they break and is trying to come up with a long term plan.
To me this reads like a Mac zealot trying to justify their use of them as a good thing rather than a well thought out argument for why they are good in the datacenter.
I see. You object to people using the tool that they know how to use, and insist they use your preferred tool instead. That's pretty typical of IT Admin types.
It also explains one of the reasons for the success of the Mac Mini Colo companies. People who can set Macs up don't need you anymore. They've developed a solution for a small project on their Mac. Then when they need the bandwidth, get a Colo service to host a Mac Mini for them. They get complete control, using a system they understand well, and have no need for assholes that like to say no. For a very moderate cost.
It's not something for big corporate solutions. But for small companies and individuals it can be exactly what they need.

No, I don't think you really do see. He told a story about some people at a university who wanted the IT department to support a unique one-off system, the IT department said no. I guess they could have said yes and handed them a bill for all of the extra overhead involved, but the result would probably have been the same.
When information is power, privacy is freedom.
News? This is a slashvertisement.
They specifically allow OS X Server to be virtualized.
... on Mac hardware only. Which brings us back to the matter at hand, needing Mac hardware in order to run Mac software.
I don't care if it's 90,000 hectares. That lake was not my doing.
What most of you fail to understand is the TCO. The hardware costs nothing in comparison to how little time they need for setup and maintenance. If one fails, big deal; get a new one and restore it from the backup and it's running with a few minutes of work. Need more capacity or redundancy? Just get another and it's running within minutes. Need more demanding mass storage and/or networking? Plug that into the convenient external PCIe bus (Thunderbolt). Basically lim(0) setup time there too.
I still run my own servers as dedicated co-located generic Linux boxes, but the setup still takes roughly a day; not hours or minutes. That time isn't billable and I schedule it to days I can't do anything productive. If something fails without warning and requires immediate action, it's a day subtracted from writing billable hours of code, which per se costs about the same as a Mac Mini Server. For the customers of mine who need dedicated units for one reason or another, the Mac Minis pay for themselves just in the initial setup work alone, and they can manage them by themselves, just like my mom is able to manage her MacBook with maybe a support call every few years, when she wants an opinion on a hardware upgrade or such.
After the Mac Mini servers got the i7 CPU's, none of my customers chose a Linux option when presented with the cost breakdown. From the software perspective, my code isn't picky about which Unix or unix-like it's running on. Almost anything goes, as long as the system dependencies are installed. OS X Server just happens to have all the system dependencies preinstalled in the shipping configuration as well as everything else they typically might need.
In a small or medium scale setup or a large scale setup of heterogenous systems, Linux is cheap only if time doesn't cost anything, or the comparison baseline is something even worse; Microsoft Windows or such. Linux-based setups may also be feasible for certain large scale installations of homogenous nodes.
I have an original 1.42 Ghz mini sitting on my desk running nightly reports. It was a CFO's desktop for a year, (for a tiny company), and it's been running reports since then.
iCal repeating events tell Filemaker to query MSSQL databases, which outputs Excel files, which are manipulated using Applescript. Mail emails the finished and highly formatted reports to various people in the company. Pretty damned easy to work with, given the magic "Record" button. I used to have it print overnight, but that became too old school.
It still has the Apple serial number in the disk info box - never even been formatted. Still has 512K Ram. Never misses a beat. I guess for 8 years now. Put that ROI in your pipe and smoke it.
I should still probably get around to backing it up someday..
Dell will sell you a 2U (R820) system that can have 4 processors in it up to 2.7GHz and 8 cores each. It can then take 1.5TB of RAM, 16 2.5" drives (magnetic or SSD) 7 PCIe cards and so on. You'd better believe you can stick more than 40 VMs on that sucker, and you can get another one in 5U with 1U to spare.
Or you can go blade server, Dell has options here though IBM has higher density solutions available, if what you want are a lot of systems in a small amount of space.
All of this supports real enterprise stuff like redundant power, ECC RAM, RAID-6 hot-swap drives, central monitoring, failed component isolation, and so on.
Piling a bunch of consumer computers in a rack doesn't really make a lot of sense, particularly ones not designed with good cooling solutions. When you start doing real high density on computers, cooling is a real issue. Servers are made to deal with it, the vent in the front, out the rear so you have have hot/cool zones and they have high speed fans if they need to spin up due to ambient increases. Mac Minis rely by and large on diffusing heat through their cases and a tiny vent at the back, which is not a winning scenario in a dense situation.
You are going to get better power usage in any large scale by bigger systems with virtualization and having them stand up and down as needed. You can do that with real servers that have full lights out management (Dell calls it iDRAC). As load on the servers rise, new servers can be powered on and made read to the cluster as needed. Also all that high end stuff can buy you realtime failover and migration so things can be shifted around as needed.
All this gets rather feasible with the costs you are talking. 8 Mac Mini servers is, minimum, $8000. That gets you 4GB per system, a 2.3 GHz quad per system, and 2 1TB drives. Because I bought one recently I can tell you that you can get a Dell R720xd will run you about $9000ish for 2x 2.6GHz 8 core CPUs, 128GB of RAM (aftermarket) and 6 1TB HDs (which will let you do RAID-6 with a hot spare and have 3TB of space). I'm not seeing what the minis gain you, and I can give you a list of things they don't have.
For all that, it is a similar power profile. The Macs spec in at about 680 watts total, the Dell has redundant 750 watt PSUs though in my testing only pulled about 600 at max load.
All that in less than half the rack space.
So other than "It can run OS-X" what are you getting with a ton o' minis?
It is $1000. That's the thing here. They aren't all that powerful and they cost a grand. So you can pack 8 of them in to a 5RU shelf, apparently. Ok, that's $8k, presuming no upgrades... Well go have a look at what you get from Dell for $8k. You can get quite a bit of server, including things like ECC RAM and hot swap disks and all that.
I can understand getting a single cheap computer as a server if your needs are low, and thus you aren't going to spend a ton. But when you are talking about tossing a ton of them in a rack, well you have to evaluate what they'd be competing against.
For data centers, it is still all about VGA. The reason is KVM systems use it. Even the big network KVMs are generally VGA at heart. The standard in servers is VGA, with one on the back, and one on the front. The back one for wiring to a KVM, the front on for hooking up to a crash cart.
Now this may not sound like a big deal but when you've managed a number of servers it quickly becomes apparent why such a thing can matter. Can Minis do VGA? Well of course, but as you noted you'll need a host of adapters. Then, of course, if there's an issue you get to wonder if it is the system or the adapter, and so on.
There's a lot done in the server world with regards to standards that is the though for not when things go right but when they go wrong. If you've never experienced the problems then you might not appreciate why but if you have, it becomes rather clear.
