Only a few months ago I was searching long and hard to find a case that had enough 5.25 bays (10+) to build a decent fileserver with ...

This tower should do the trick. You can fit 12 hot swap drives in a 2U, but if you want something quieter, less expensive, and with space for your 10 drives and have room to expand, a proper 4U chassis is what I'd think you want.

A 4U, incidentally, can be as quiet as comparable desktop. And with a custom cabinet (with or without rails), it will look a helluva lot nicer, not to mention that you'll have none of the cabling mess, etc. typically associated with tower setups.

The five-drive cases suck rocks when it comes to cooling. There isn't enough space between drives to move the air. Thermaltake's 4-drive converter actually keeps the drives cool, improving their life span.

I have 4 of these in an Antec 1200, and with the stock fans replaced with Noctua NF-B9 fans, it's not only nearly silent it keeps the drives under about 38 C (100 F). Since Google's research showed no appreciable correlation between drive temperature and failures rates until ~45+ C, that's good enough for me.

It even uses the power.

Indeed. Only a few months ago I was searching long and hard to find a case that had enough 5.25 bays (10+) to build a decent fileserver with, using these. Eventually I managed to find an Antec 1200 at about 50% off list and went with that, but damn it was difficult find _any_ cases with that many bays, that a) weren't rackmount or b) weren't stupidly expensive.

What about Supermicro's 96-core 2U box?

Backblaze uses, and specifies (it's not a kit, BTW - just a parts list) , which is among the design choices deemed 'flawed' by many.

If it suits your needs, great. Protocase and Newegg would like your business. If it doesn't make the 'quality' cut, SuperMicro sells nice stuff.

If not, a suitable JBOD solution hunt isn't exactly news.

I work for a small ISP and we encountered this recently.

We bought a few SuperMicro small form factor chassis (http://www.supermicro.com/products/chassis/1U/512/SC512-260.cfm), and found that with the drives positioned directly next to a high speed prop, the performance of the disk went from a static 125Mb/sec to as low as a few kb.

The drives we initially bought were WD 1TB Green Drives, and we thought it was initially a "Green" feature. But with thorough testing (and after replacing the drives with Barracudas which suffered, but not as badly), we concluded the fault was singularly because of the vibration.

In the end we packed the prop with foam padding -- between the drive and prop, padding the drive's power cable, and between the prop and chassis (above and below).

Problem went away. But it took us a couple of months, a LOT of back and forth between our supplier, the distributor, and SuperMicro (the latter ignored it), and cost us a bunch more money and time than we had quoted our customer for.

I assume this is in response to the $200 Intel Atom based servers out there now.

I only wish i could find a i7 MB with a Sas controller, I may have to buy a used one :(

Here.

There are server boards out there with pelnty of PCIe slots e.g. http://www.supermicro.com/products/motherboard/QPI/5500/X8DTH-i.cfm (shamelessly grabbed from a board in a picture linked from another post here)

Yes you will need a case tall enough to take cards without risers (which means 3U afaict) but I would guess getting the same IOPS any other way would take up way more than 3U of rackspace.

WOW NICE motherboard there, TWO io hubs to give seven of x8 electrical/x16 mechanical slots along with a x8 link for the onboard SAS and an x4 link for the onboard dual port gigabit.

http://www.supermicro.com/products/motherboard/QPI/5500/X8DTH-i.cfm

Oh, yeah. We a team need highly skilled specialists to assemble this stuff and configure it. Guys that know what attaches to which and what bandwidths and clock speeds and stuff are. Because that's all really complex and detailed. If we don't handle this ourselves we can shuffle along with much less competent people than can be found at the local voc tech, just by relying on the vendor to steer us right.

For folks who don't like OSS I did mention Windows Server, which has clustering and management just like all your other Windows servers. Microsoft is really underdelivering on their messaging here. Windows provides quite a competent storage solution that's very scalable and quite inexpensive for larger storage sizes.

People aren't really using the BackBlaze boxes so much as stuff like this. I just include the BackBlaze stuff because I think it's really cool.

If as a business grows it needs more and more storage in the hundreds of terabytes, don't you think that paying millions of dollars for SAN is going to rate limit growth somewhat? Most people aren't making Avatar you know.

Home PCs may typically use 5V for the primary voltage, but servers with redundant supplies frequently use 12V input.

Whoops - it's a SuperServer 5015A-H (see http://www.supermicro.com/products/system/1U/5015/SYS-5015A-H.cfm?typ=H). Stupid me didn't copy/paste.

Sure, you could do it with a cluster of workstations. You would need some insane interconnects. OR, you could just buy this pre-configured system from SuperMicro with dual quad-core Nehalems and 4 Nvidia Tesla C1060 GPU Cards. That's 960 thread processors @1.3 GHz if you don't overclock, 16GB of DDR3 @ 1.6 GHz on a 512 bit bus, 16 threads of system CPU with up to 96GB of system RAM. It pulls close to 4 TFLOPS, in a desktop machine. You probably could break into the top500 with ten of them with decent interconnects since the #500 spot is Rmax 17.09 TFLOPS and Rpeak 37.64 TFLOPS. If you prefer a top 3 OEM, you can get that in a Z800 workstation from HP.

To put that in a time scale for you, that one desktop available today by itself would have easily been one of the top 100 supercomputers in the world only five years ago and would still have been in the top500 3 and a half years ago.

A little spendy for a wordprocessing and light spreadsheets, but a sweet piece of gear nonetheless.

http://www.supermicro.com/products/accessories/addon/SIM.cfm

Some Super Micro Motherboards can have IPMI (which does all of that) added to them for a very small fee.

other brands like IBM / HP / etc also have some sort of functionality like this but will charge you licensing for the same feature set.

SGI had an Atom-based supercomputer on the drawing board: http://www.pcmag.com/article2/0,2817,2334887,00.asp

Quote:

"The key to the concept, SGI said, was its Kelvin cooling technology, which could pack 10,000 cores into a single rack. Combining the Atom processor with the Kelvin technology could generate seven times better memory performance per watt than a single-rack X86 cluster. Molecule could also process 20,000 concurrent threads, forty times more than the rack, and 15 terabytes/s of memory performance, SGI said."

Supermicro makes a nice server MB with a dual-core Atom 330 CPU:

http://www.pcmag.com/article2/0,2817,2346555,00.asp

Quote:

"The X7SLA-L platform from Supermicro is designed around the Atom 230, a single-core chip from Atom that consumes just four watts. The server itself packs four SATA ports with RAID 0, 1, 5 and 10, along with seven USB 2.0 interfaces, 2 Gbytes of DDR2 memory, Intel GMA 950 graphics and a Gigabit Ethernet port. The more robust X7SLA-H uses a dual-core Intel Atom 330 processor, and doubles the Gigagbit Ethernet ports, adding an additional USB and serial connector as well."

64GB of memory has been supported for a LONG time, especially with server class hardware. Usually requires a Xeon or Opteron processor.

From 2005: Opteron based: http://www.digitimes.com/mobos/a20050729PR208.html

Xeon based: http://usa.asus.com/products.aspx?l1=9&l2=39&l3=712&l4=0&model=2147&modelmenu=2

How about 256gb? http://www.supermicro.com/Aplus/motherboard/Opteron8000/MCP55/H8QMi-2+.cfm

From SuperMicro and price what it would be like to max it out on RAM and processors. You'd need a custom case for it to make it a workstation pc rather than a rackmount. Comes to about $20k with 96G of RAM and 4 6-core Xeons -- still less than what Dilbert spent for his dream system.

The big iron that Solaris runs on are enterprise scale database servers, which are optimized for an entirely different set of performance parameters....

which is a relatively small market that is rapidly being marginalized as commodity hardware increasingly becomes capable of matching the performance requirements of such large-scale databases.

I remember an "enterprise solution" based around a Digital Vax 11/750 that filled a good-sized room, with 3 300 MB hard drives, each the size of a large dresser drawer, linked with ungodly amounts of copper wiring. Now, the $20 2 GB USB 2.0 thumbdrive I bought at Costco provides more storage, faster, for cheaper. (See a trend, here?)

I'm not arguing that Solaris-based solutions aren't better for this task, I'm just saying that this fact becomes less and less important as cheap, commodity hardware with a free Operating System and DBMS becomes more and more "up to" the task. There is an awful lot that you can do with a few of these guys, even if they don't qualify as "big iron".

There still is a place for mainframes, there's still a place for "big iron". But both places are shrinking while the overall marketplace for data management solutions continues to grow exponentially.

Oops, getting a bit dyslexic :P
It should be the AOC-SAT2-MV8 : http://www.supermicro.com/products/accessories/addon/AOC-SAT2-MV8.cfm

the 5000x chip needs FB-DIMMS that cost more then DDR 2 ECC.

A dual cpu dual quad or dual dual-core system with 2 to 4 gb per cpu will cost less + you can get a board with the nforce pro chip set.

up to 32 GB DDR2 667/533/400 ECC ram + on board sas hardware raid also High-End PCI-e Graphics (SLI Supported)

http://tyan.com/product_board_detail.aspx?pid=541

Tyan and Supermicro, which both focus on the server/workstation market, are the only motherboard makers I've heard about releasing motherboards based on the 5100 chipset. If you trust the Intel brand for reliability, then I think this Intel chipset on a Tyan or Supermicro motherboard might be a decent compromise.

• Tyan Tempest i5100X (S5375) - Seems to be out of stock everywhere (searched Google Products), but it's being listed at about $320 to $400. It's a server board, but it looks like it would make a decent workstation (PCIe x16 slot, integrated audio, extended ATX size).
• Supermicro X7DCL-i - In the same price range as the Tyan board, but seems to be available at a few online stores (like this). Standard ATX size, but lacks PCIe x16 slot.

Supermicro just came out with some cool workstation boards that support the Seaburg chipset that's 1600Mhz. http://supermicro.com/products/launch/Intel/#MB5400

I incrementally dump(8) my important few hundred GB to a rotated pair of 500G drives. I could do with an extra hot-swap caddy and something to store a drive + caddy in when it's not online, but it seems to work pretty well.

My home server lives in one of these, but standalone and 5.25" bay hot-swap SATA racks are pretty common.

20% decrease in memory access time with DDR3 and the new Supermicro CS2BX workstation motherboard. Benchmark results coming in 1 week time on http://www.supermicro.com/

How hard was that?

Prob something like this, perfect for firewalls:

Using another semiconductor than silicon for the CPU? Or a radical change in the design of the CPU or orther components? Are there experts here who can elaborate on this?

Performance per watt is a biggie for chip manufactures. Having a less than 10 watt server chip is possible, but who wants to use a Palm Pilot for a transaction server?

Having the performance to handle a slashdotting is what is needed in many servers. Performance is first, power consumption is second. That is why the performance per watt is an important part of the chip design. Low power chips is not the main design item. High performance is the most important. Providing that performance at the lowest power possible is the sweet spot chip designers aim for.

Here is additional reading. Look at what the Core 2 Duo and quad is bringing to the server market.
Please note the Woodcrest and Operon is now obsolete. The Operon was leading, but the new multi-core chips are a new race in the performance per watt race.

The nice part, however, is that web-serving is so easily and cheaply scalable that it's almost pathetic. If your alternative is to buy an extra few megabits (at guaranteed bandwidth rates, not shared-connection rates), then for what you'd pay for bandwidth in a single month, you can throw in another Apache machine to help carry the load.

I'm pretty excited for "hardware season" this year (making purchases to accomodate growth in our peak season). These are sexy, cheap, and compact. At 14" deep, I can double them up, mounting them in both the front and back of the rack.

AMD quad-core chip will have shared L3
also lack of quality of the interconnect for intel means that you will like not see a duel cpu system with out a non intel chip set. And the nforce pro chip sets have sli with 2 full x16 slots and left over lanes for x4 slots while most intel ones don't even have 1 x16 slot at full speed.

crap... wrong link... was supposed to link the P4 cases. which are shorter (with the 1x SATA)
http://www.supermicro.com/products/system/1U/?typ= P4

shorter 1U rack cases are available, but I dont know how short is needed for the rack used by the OP.

really, you almost only need 4U of space. 1x 1U Rack display/keyboard, 1x 1U KVM, 2x 1U Server cases. Keeping the height to a minimum will possibly allow the depth of the equipment to be increased.

8x 2.5" SAS drives in 2x 5.25" bays, available now from Supermicro.

Xtore has a 2U 24x SAS JBOD here

I imagine that an array with vertical bays and a pull-out shelf type arrangement could comfortably handle about 80 2.5" SAS drives in 3U of space. Power and cooling issues abound, however.

LSI and others have 36 port expander ICs arriving in the pipe now. HP recently unveiled a few new server models that house more than a dozen drives (Proliant ML570 G4 with 18x drives.) 2.5" SAS is going to make a big impact. DBAs love spindles and 2.5" drives make lots of spindles easy.

8 drive 4U Supermicro case. And here's a 7 drive one, which I have running in a cupboard a few ft away. SCA, fixed bays and more modest variants abound.

And here is a 12 drive Lian-Li, although you need to be very careful with cable routing and PSU/fan choice to fit them all in and keep them well cooled (the 6 drive one is awful for this). They also lack a reset button for some reason.
