Building a Budget Storage Server
An anonymous reader noted an article running over at Firingsquad talking about
building a budget storage server. Talks about cooling, power, RAID, expandability, etc. Good overview type article, with practical application.
Their definition of "budget" is $3,140? Someone give me their budget right now!
Since they couldn't afford RAID, what about software RAID? Way faster than normal IDE operations.
This is a test. This is a test of the emergency sig system. This has been only a test.
Article is lame when it comes to the important stuff. Its great he gave us the hardware to do it, but thats not the important part now is it? Software.... something that can do backup's to harddrive and then take backups and archive on tape. we went with tapeware because of price, but we cannot archive a current backup to tape, so that means we have 4 week online and no archive really (bad). Are there any open source solutions? I saw a couple but they look hard to setup and manage. Tapeware gives a powerful interface and makes it easy to backup from multiple machines... plus linux boxes don't need special server license (unless they have a tape drive) where any Windows 2000 Server box needs a server license.
No raid? Going to rely on the drive's MTBF? WTF. A raid controler is like 80$ MAX and one additional drive is like 250 or so. Spend the damn money. While you're at it. Invest in a tape drive. You're data is more valuable than the drives.
... it's possible to buy a large PC case and fill it with a large number of drives that add up to a volume of storage that was once considered to be large several years ago. What's new here?
The article could have covered a little more than just the hardware needed to run such a setup, perhaps covering some sort of remote management interface for the storage? It would also have been nice to hear if they solved the problem of backing up this data on a budget too. (Ingoring the possiblilty of burning the data to DVD).
Just yesterday I brought up a server here at work to server as a 1.0 TB-range backup server using 8x200gb WD 8mb cache drives strung off a 3ware escalade controller (raid5, two hot spares). The build process was suprisingly painless (used an athlon-based solution but that's relatively unimportant. you'll want 64bit/64mhz pci slots for things like the 3ware storage card, scsci card to drive a tape drive, etc. the cheapest board I found that could do this was ironically a dual CPU MPX chipset board from gigabyte, sub-$200), with a total cost for a total beast of a machine coming in at about 3400 USD with shipping and such. I'd recommend heartily the 3ware controller cards if you want to try something like this, they're worth every penny of their ~200-300 cost simply for the increased performance and reliability they bring to the table as well as the reduced hassle (the array just shows up as a single huuuuuge scsi drive to linux... always nice when /dev/sda is
reported to contain something like two billion 512 byte sectors ;)). I went with a black aluminum Lian-Li case because it has enough 3.5" drive bays to hold all those drives, comes with lots of fans by default (as well as cooling a bit better than your average plastic / steel case due to the thermal properties of the material), and a monster 550w "vantec stealth" powersupply for reliability and the ability to sustain all the devices in the system. Debian stable installed with zero hassle and now I'm just left with the pain of fighting with backup software. ;) True, I'd trust something from Sun or similar more than this homebrew thing, but this is also a mere fraction of the cost of something from the commercial Unix vendors, so for the same total cost I could have multiple redundant servers... or more ale-and-whores money in the departmental budget. ;)

"How to build a budget file server without knowing what we're talking about"
3 grand is on a budget? What happened to raising from the grave an old AMD K5-166, throw some big IDE drives and you really got a budge file server.
This is a test. This is a test of the emergency sig system. This has been only a test.
I agree, that seemed much more like, "Watch us build an expensive PC with a lot of hard disks" than "Watch us build something useful for reliable network storage."
I am currently trying to put together a RAID 5 file server and they do not cover any topic of use to me in that article. For example, practical backup solution? They chose a DVD burner, why that over similar tape solutions? I would guess price, but it would be nice if they at least mentioned some of their considerations. Especially since it would take 112 DVD-R's to back up a terrabyte?
Also, aside from their DVD backups, they seem to have no data recovery plan in case a hard drive fails. I guess they aren't storing anything important on these drives?
Look at the banner on the pages -- "Home of the Hardcore Gamer". It's because they're gamers and know everything about tuning a system for games, but don't know the first thing about building a server. What they've ended up with is a mish-mash that won't serve any particular purpose well, except possibly as a rather decent PC for a secretary (except no secretary would want something that big at her desk).
As one reads through the article, what leaps out is that they're most comfortable when debating relative merits of 3D video cards and building uber-fancy custom machines designed for gaming excellence. Good for them, but this is far removed from building a server.
It's got a terabyte of utterly unsafe storage. No RAID, no nothing.
It's got a video card which is overkill for a server but which they disdain as a low-end 3D graphics card.
They've got one hard drive for the system and everything else as data, so they're not building a "high performance" system or else they'd have a separate drive for paging.
They haven't discussed the types of files they'll be storing at all -- will they be tiny text files, medium sized spreadsheets and documents, or massively large presentations and CAD files? This affects how you configure your system.
Their approach to planning for hardware failure is "we bought the better quality stuff so we don't have to worry so much about MTBF". No need for RAID or redundant power supplies. (Although oddly enough they've chucked in two NICs.)
Did I mention no RAID? Yet they've bought a 3D graphics card (overkill), a nice mouse (in case they want to do graphics editing or perform fast wrist actions on their storage server), a wireless keyboard, and a fun little LED display to tell them how fast the CPU fan is spinning.
Look at how they're future-proofing the system, by the way. They anticipate going through 2 TB of data every year. So every six months they're going to pull out the existing 1 TB of storage, plop into an external array, and put in a new set of disks. I wonder how long this system is supposed to last...
All in all a very odd system indeed. In fact, a pseudo-server built by gamers with no understanding of how to build a server.
They spent $300 for a Pentium-3 and $200 for a high-end motherboard and $350 for the fastest most expensive memory they could find, when a "budget server" could do just fine with a ~$100-150 2GHz CPU+motherboard and $200 for 1GB of average-speed memory. (Their motherboard does sound good, though.) After all, the bottleneck here is the disk drives and network, not the CPU, though even on a budget server it's probably worth having the 1GB of RAM for caching and for staging CD or DVD burns.
The $190 power supply seems expensive, but that may be realistic for a system that can expand to 8 drives. If you've got a UPS, you may not need as high-end a power supply, and a "budget" system might get away without it, but since they were too cheap to buy a 5th drive for RAID they're probably much more in need of highly reliable power. And their 3GHzP4 CPU and overpowered-for-a-server video card use too much power and put out too much heat - you can easily save 50-75 watts by making better choices, and probably 100. You could save even more by using a motherboard with built-in 2D video, but most of those don't have the high-performance networking support yet.
Also, they didn't have a price for an operating system :-). That means that they're planning to use Linux, which is another reason not to waste power or cooling or money on a gamerz video card...
