Interesting project. You need to nail down your requirements and your budget, and that will help you nail down what hardware you need for your design. Step back from the "1TB drive" decision for the moment; a year or two from now that will seem rather limited. Also consider how badly you want the ability to use 20 drives in this system -- that's a lot of ...

Well this is a LITTLE bigger than what you want, but the design/architecture, on the hardware side would be close to what you need. Finding a 20 drive, or even a 15 drive case is gonna be tricky though

There are several Adaptec, 3Ware and Areca RAID controllers with 24 SATA ports available. Keep in mind that agreggating 20 drives mean you're having 20 times more chance of a catastrophic failure, so RAID-5 or RAID-6 really is mandatory. You can also add drives to a RAID array with those professional RAID controllers. So my advice is to start with one of ...

You are probably getting freezes because you are exporting NFS shares with the "hard" option (which is the default). You can change that by using explicitly the "soft" option. The NFS man page has more. mount -o soft <nfs server ip>:/mountpoint /local_mountpoint Then in the clients you should no longer have a problem with freezes. As for a ...

Before you get to converting sync writes to async writes, you have a lot more problems to overcome: If this is a gaming system, how are you going to make sure that your VM doesn't crash in your intense gaming session? How are you going to make this VM visible on the network? Will your drive be able to take the abuse of a mongo 4TB virtual hard disk? (ZFS ...

ECC seems to correct only single bits errors. Correct. To correct more errors would require more bits. As it is, you already use 10 bits to store 8 bits of information, 'wasting' 20% of the memory chips to allow to a single bit correction and up to two bits of error detection. It works as follows. Imagine a 0 or an 1. If I read either then I just have ...

Like Antoine said: An Atom CPU and SW RAID is a bad idea. To measure the troughput of your disks you can use hdparm. Have a look at this: http://www.cyberciti.biz/tips/how-fast-is-linux-sata-hard-disk.html You should measure your disk devices and your raid devices seperately. That way you can see if the disks are slow (broken?) or the RAID is slow. Also ...

yeah, there are many routers nowadays with usb ports that you can plug in an external drive to act as a file server as well, such as Linksys E2000. you can just search for routers with usb port and find many more.

Sounds like you're looking for a NAS (Network Attached Storage) You can buy pre-built ones from companies such as Netgear (Ready NAS) but this road is generally expensive. You can also build one yourself using old parts- NASs don't require the latest and greatest parts, I have mine running on an old 1996 Compaq box with 512MB of RAM- I only had to buy a ...

On the Mac, you can use Connect to Server... under the Go menu to mount the network volume, and opt to store credentials in your keychain. Then once the drive is mounted, you can create an alias to it (Make Alias under File menu, or command-L). That will allow you to double-click the alias and have the drive mount when you need it. You can also set up the ...

Apache is a HTTP server. It means it's for websites, not file streaming. It just won't work. The easiest solution for your problem is probably Dropbox. Just create an account and send your friend a referrer link, after he registers using that link you'll both get 500 MB extra space (that's 2,5 GB for free). Then you both install the Dropbox app. One of you ...

I agree with the comment from Frank Thomas, using Linux does not preclude you from using Samba. I would prefer NFS shares in an all Linux environment as do a lot of other people but Samba is perfectly fine as well. It is not the only solution to your problem though. Try looking at your NFS mount options. Specifically, look into the intr, soft, tcp, timeo= ...

One way to tackle this is a scheduled task running daily at 12AM using robocopy on ServerA. The command line for the scheduled task would be robocopy drive:\path\to\share \\ServerB\share /mir. Robocopy has MANY more options that you may want to explore but this simple syntax will mirror a directory structure from the first path to the second.

This won't apply to Linux, but we use Microsoft's App-V. The virtual apps can see mapped drives, printers, etc. just like installed apps can. Also, we served thousands of clients from one 2.8 GHz server when we first started in 2007. Your mileage may vary depending on the virtualization software chosen, but I hope this helps in a general app virtualization ...

Try using Windows Home Server. It does everything you want, with minimal configuration, including backups, versioning and directory shares. It also has some media sharing features. Alternatively, you can convert your PC to a NAS. There are many solutions and distros that will allow you to do that.

A couple of things to check: make sure the NIC is actually in Gbit more, not 10Mbit with ethtool eth0 (replace eth0 with the relevant NIC's device ID if different), look for the "speed" reading for the current mode verify that Windows is currently using its card in Gbit mode too check to see what CPU and I/O load is imposed on the server during the ...

From Tom's Hardware : 2.5 TB HDD Expected in 2010 (August 7, 2009) A recent roadmap presented by TDK Corporation--a manufacturer of read/write heads for many hard disk drive (HDD) suppliers--revealed that 640 GB 2.5-inch and 2.5 TB 3.5-inch HDDs should become available around January 2010. For now, Seagate and WD provide HDDs with the ...

Set up Samba. Then you can either have her manually drag and drop stuff she wants backed up over to there or you can set up some automatic process on her machine to do so every so often.

This is my setup and works great. Headless Ubuntu server hosted on this: http://www.newegg.com/Product/Product.aspx?Item=N82E16859321014&Tpk=acer%20easystore you have 4 hotswappable bays

Something like a Synology DS410 might work or the higher end DS1010+. It doesn't support Squeezbox but does have a streaming service (among many many other features). ~Edit, it actually does support Squeezbox One of the Synology devices seems to be the most efficient solutions offering quite a few features for a decent price, and I believe it meets most of ...

I think you have two options: Buy a Home NAS like this, with low consumption. Use a standard PC (after testing ambient and hardware temperatures)

You can try FreeNAS. FreeNAS is a free and open-source software network-attached storage (NAS) system based on FreeBSD and the ZFS file system. It is licensed under the terms of the BSD License and runs on commodity 32 and 64-bit x86 hardware. FreeNAS supports Windows, OS X and Unix clients and various virtualization hosts such as XenServer and ...

Like Alex pointed, there are dedicated distros for building NAS. check this site for a quick compare for the various distros. Now you have to think if the energy wasted by one old PC is not too high. Older PC were made to be "fast" and power consumption were not a priority. Newer PCs are usually more green and you may even save money by buying a new "light" ...

This is a very situation based question. If you are a large to medium sized company then you should already have a file-server. If your a small company however then it also depends on what you do. Sensitive information (Social security, Medical, important records, ect.) should never be stored in the cloud. That information should be stored on a local file ...

You can use Btsync to sync files between folders on different devices. It works really simple. After installing, you create a share by selecting a folder and creating a code. It's easiest to start on the laptop. Create a new folder for the syncing, and copy files to this folder. If another device deletes files here, they might be lost on all devices so you ...

Let's look at how your suggestions might fail to provide the goal of usable backups of data, shall we? 1) To buy a SATA RAID controller card (HP or Adaptec) with battery, place it into the Hyper-V server together with some bunch of disks, create a RAID 6 volume on it and make it a storage for the fileserver (possibly also for the other servers) using ...

To break the net connection, just schedule a similar .bat file every few minutes : @echo off tasklist | find /i ".scr" && net use x: /delete If necessary, you can hide the .bat file by using this answer. But just to remark that I take no responsibility for what happens when the other users of this computer lose their work because of this ...

People typically define a file server as a machine that is designed purely for sharing files. Such a machine could be anything, but generally a good file server should aspire to have the following features: Minimalist OS Minimal overhead software (i.e. little or no virus scan, etc.) Automated update / self cleaning / self management features where possible ...

If you're just worried about problems from wearing out your disk again, you can get a plain old external disk enclosure for around $50 that supports 2 mirrored disks (disks not included). This protects you against a single disk failure. Update to answer the comment: NewEgg Tiger-Direct Amazon CDW The key thing you're looking for here is support for ...
