I had to add a bunch of new OS and Drive types.  I also am sure I missed at least one system of note that didn't have five drives.  I'll go back and find that to add next time.  I was able to get colonel_mortis, one of the mods, to put in the html for me into the front page.  Big thanks for the help on that.  I'm going to update the github repository with the updates I've made to the configuration pages.  I'll keep an eye out for some updates and maybe try making another update then.  Or maybe just when I add some drives to try to get a better rank myself

Update #1 
 
Long time since I've posted here and the storage situation has changed quite a lot. Gotten an interest in rack servers and I now have had a Dell PowerEdge R515 as my dedicated storage server for almost a year.

Software and Configuration:
 
The server is running FreeNAS 11.1 and I chose FreeNAS as I wanted ZFS for the additional data security and just to try something else than Windows.
 
The SSD is just sitting there unused as I would have to move the ESXi server that is on top away to take it out.

HDDs are set up in 3x ZPools:
4x3 TB drives RAIDz1 (RAID5) for 9 TB formatted. 4x4 TB drives RAIDz1 (RAID5) for 12 TB formatted. 4x8 TB drives RAIDz2 (RAID6) for 16 TB formatted. In total I end up with 60 TB raw or 37 TB formatted (bit less due to using ZFS). 
 
Usage:
Storing personal files, backups for family, media and Veeam backups (VMs) .
 
Backup:
The most important files are backed up to Google Drive.

To be honest it most likely will. A speed of only 1Mbps is most likely causing you a slight excess of ping due to queing as the ISP limits your link. Speeding up the connection will remove some of that queuing and and you may see reduced ping. However the most important thing is where the services you are trying to connect to are located.

I'm new in this thread, and fairly new to the forum in general, so i thought i would "pop my cherry" so to speak by showing off my little baby

The server is running Microsofts StorageSpaces on Windows Server 2012. It fits my drive config, and the speed is perfectly fine for gigabit connectivity. 
 
I'm only using this as a file / Plex server at the moment, but it probably will be used for some Hyper-V stuff later on.
 
The storage is configured as one drive-pool with two virtual disks. One big disk for media configured as parity, and one smaller disk for documents and more important stuff which is configured as a mirror over three drives, and is backed up using Jottacloud aswell.

Hey everyone,
 
I'm just posting this and marking it as best answer temporarily so that everybody can easily see it.
I'm currently only very rarely online due to bad health and it will be a while until I'm really back.
However, once I am, I will go through all new and updated entries and update the rankings accordingly.
 
So just keep posting your systems!

UPDATE #2:
 
If you don't care to read my horror story skip down to the second bolded sentence.
 
Things weren't looking good for me. I nearly lost ALL my data, and the root cause of it all was my decision to use cheap consumer drives in an always on RAID environment. Heed my warning, STAY AWAY FROM SEAGATE ST3000DM001
 
A little background story. I originally bought 8 - 3TB ST3000DM0001 and was running them in RAID 6. Late november early december I ran into a massive string of failures. I lost 3 drives in 3 weeks. I had a spare availiable, and thankfully all of them were covered under warranty, so I got them replaced for free.
 
2 weeks ago I started to run out of space on my array. I had 1TB left out of the 16.3TB. So I got rid of my dedicated hot-spare and added it to the array. This is where shit hit the fan. The expansion should have only taken 3 days as it has done so in the past, but the expansion took a grand total of 9 days. Which definitely had me worried. But I wasn't going to disturb anything. According to the logs, 10 minutes before the expansion finished, another drive died on me. (that makes 4 of the original 8 within 2 years) I didn't really think much of it at the time. The expansion finished and megaraid reported the new size at 19TB, it was just degraded.  So this time I bought a nice HGST 3TB NAS drive, and put that in to replace the failed drive. But when the rebuild finished....things took a turn for the worse. The OS was only able to see the array as 16.3TB, it was as if the expansion hadn't actually worked. I know when you expand you also have to move the GPT data to the end of the disk and then expand the partition. However the OS reported the drive was only 16.3TB.
 
On top of this, the alarm on the card would not go off. I scoured the logs and saw no problems that had not been taken care of. Yet something was clearly wrong. The alarm would not turn off, unless I did so manually, and the OS could not see the expansion.
 
At this point, I had no effing idea what was going on with my array. But the OS could still run, and I could still access my data. So I left the server alone for a couple days while I did some research. Unfortunately at this point though, I was now getting non-stop kernel panics. The OS was reporting that the device had taken longer than 120s to respond, and so the kernel halted waiting for the array to respond back. The entire OS locked up and I was forced to hard reboot. 
 
This kept up for the next 2 days and the random kernel panics and hard resetting corrupted my filesystem...then the panic set in.
 
I was able to repair the damage done, and verify that my data was in tact. But I just couldn't take this any longer. My stomach was in knots from nearly loosing all of my data from the past 8 years.
 
I snapped and bought new drives. I don't like to do this, but I had to throw in the towel. The system had beaten me and I could not stand to lose my data.
 
SOOOOO on to the juicy stuff.
 
I bought 8 - Hitachi HGST 4TB NAS drives. I picked these over the WD RED for a number of reasons. These drives are comparable to the WD RED PRO line, but they do not have the price tag to match. The drives are 7200rpm, and come with a rotational vibration sensor. Something the WD RED's don't. On top of this the drive supports TLER, is rated for 1million power on hours, and comes with a 3 year warranty. All identical to the WD RED. All this doesn't even come at a much larger price premium. On newegg, the WD RED 4TB drive costs $166, where these drives are around $175. I managed to get 5 of my 4TB drives on sale for $160, and then I had to pay $175 for the last 3 since the coupon had a limit of 5 drives.
 
Since I was buying new drives, I decided to buy another SSD so that I could run my SSD Cache in RAID 1 and safely enable write caching. I just got a crucial MX100. My other SSD is an OCZ Vertex 4. So I wasn't too worried about matching performance. Basically, the cache drives are used to speed up read/write speeds from my array. Data read from the array once is moved onto the SSD cache for faster access times. When I am writing data, the controller will write the data to the SSD and report back to the OS the transfer is done, and then it will move the data from the SSD to the disks at a more convenient time. This feature REALLY speeds things up. I did some rough testing, and I was getting around 1.2GB/s write speed, and 1.7GB/s read speed. I didn't do much to validate the results, but the numbers were enough to convince me it was working. Previously, I was getting around 600MB/s write speed, and 800MB/s read speed. Fun fact, according to the manual my raid card tops out at 1.8GB/s
 
I put the new drives in my system and set them up in RAID 6 and used rsync to transfer the content from the bad array, to the new one. rsync is nice in that it will hash check the new file against the original to make sure there was no issue with the transfer.
 
Once I had migrated my data off of the bad array, I booted back into the cards bios and deleted the array. Soon as I did that the alarm finally stopped going off. Whatever it was that had went wrong, had now been fixed...with money lol
 
My OS drive got corrupted with all the kernel panics as well, and i didn't care to go rescue my data from it. I had an image from mid january 2015 that I just copied back onto the system.
 
I plan on taking the crappy 3TB drives and individually filling them up with my data; and then I'm going to put them back in the box my new hard drives came in, and store them in my basement. This will give me a dated offline backup incase of any future catastrophe.
 
I also took the 3TB HGST NAS drive, and I replaced the previous 2TB drive I was using for downloads.
 
To help make things easier, for those that haven't been keeping up with everything. Here is my current configuration.
 
Hardware:
SSD 1: 2 x 120GB SAMSUNG 840 EVO (RAID 1 for the OS)
SSD 2: 1 x 128GB OCZ Vertex 4
SSD 3: 1 x 128GB Crucial MX100 (RAID 1 w/ SSD 2 for SSD cache)
HDD 1: 1 x 320GB WD Black 2.5" (for storing VM disks)
HDD 2: 1 x 250GB Hitachi Travelstar 5k500 2.5" (for backing up my /home/ folder and some application config files)
HDD 3: 1 x 3TB HGST Deskstar NAS
HDD 4: 8 x 4TB HGST Deskstar NAS (RAID 6)
 
(36.066TB ~36TB )
 
And now for the pr0n!!!

Update No.13
My lucky number, and final update!

 
 
 
Hello my friends!
 
In this update, I am proud to present to you the posting of the Redefine project, and the final photoshoot of this beastly machine. I am very happy and sad to see this project complete as I have had a blast working with this chassis, all the products and various materials. I cannot say that everything went problem free though as I had some driver issues and software problems to deal with which took 3 days of my life, wasted on trying to get this system up and running. 
 
I am happy to report that everything is now working perfectly, and I have installed Windows 10 Preview and played a few rounds of Battlefield Hardline.! BTW if anyone wants to have a match on BF4 or BFH please add me at metallicacid_01
 
But before I get on with the image onslaught, I would like to take this moment to thank my sponsors who have giving their time and products to make this project come to life. Without your support, I would not be able to create these projects that I love to create! Thank you to:
 
Inet
Corsair
ASUS
Ultimate Personal Computer
Dremel
 
 
 
So firstly I want to show you some awesome custom engraving made by the owner of this project, Jens. He is magical

I really hope that you all have enjoyed this projects' build log, and the finished resulting PC. It has been a pleasure working on the chassis, and having all of you joining me once again in creating another custom project!
 
For those of you wanting to know what is next, I have a few projects in the works, and hope to start with a personal HTPC project right away. Once I have some more confirmed information, I will set up a build log and inform you all where you can find me
 
That is it for now, and thank you for following. I hope to see you again in the next project!!
 
Kind regards,
Justin "MetallicAcid" Ohlsen
 
 

Not to make @looney feel inadequate, but I'm about to upgrade my server from 2TB usable storage to 7TB usable storage, so you have some stiff competition! 
 
*Weeps in corner*

I used to always buy used servers.
For example my old ESX server was a DL160G6.
 
However before building this server I ran into some money and I always wanted to build a massive array with nice Supermicro gear hence the expensive new stuff. 

Great harware! Can't wait for more updates. Did you ever consider buying used servers (except for the harddrives) to save money?

More to come tomorrow, pics of the building process of the JBOD will have to wait till mid February as I kinda forgot to take pics and I will have to open the server up again to take the pics which I will do when I take the server to a LAN in min Feb.

Unboxing the small box with parts.
 
The first thing I did when I received the package was open the box on top that holds the HDD's CPU's SSD's and BBU.
 

 

 

 
 
When I was done with opening this box the doorbell rang and I received this:

Currently at idle its using about 5-6 Amps at 1300W - 1400W
 
Cost on idle I think is arround £180 a month. Ex VAT
 
With regards to on full load.  This I havent tested yet,  But will probably turn out to be just under double the numbers above.  When I do ill reply back to this

Maybe, maybe not, impossible to tell. See Emerald's response.
 

Anything that is stored anywhere can be affected by bit rot. Though bit rot is by far not the only thing which can corrupt data.
 

I'm not up to date on Windows, so can't answer that. I've never read anything about Windows having protection mechanisms against data corruption in place though, at least not on NTFS, but just because I haven't heard of it doesn't mean it doesn't exist.
 

Just refreshing the data on the disks is not much good in and of itself though, you'd need to have a mechanism in place to ensure that the data hasn't been corrupted (checksums), and to make sure the source data hasn't been corrupted (it's no good if the data on the backup drives is still good but the data on the source drives has been corrupted and you copy the corrupted data onto the backup drives).
Personally, for any external drive I use for backups, this is what I do:
1. Create checksums for the files from the original data source (HDD); the kind of hash algorithm you use isn't that important, I usually use SHA1 (like git), but you can use MD5 or another SHA variant, w/e.
2. Store those checksums. I store them on the original HDD, the backup HDD and I print them out on paper (only the ones of really important files though, because printing out hundreds of pages of checksums for several million files is a bit expensive and time-consuming). The reason for printing them out is that the checksum files themselves can of course also become corrupted.
3. Copy files to backup drive, verify the copies against the checksum files.
4. The important files I verify against the checksums every month, the not-so-important files every six months or so.
For protecting the original data, I use ZFS on my server, and do about one scrub per month (and yes, it has ECC memory and all that).
 

Yes, this is a thing, it's just not a thing regular users normally are informed about or care about because it's not frequent enough, and even when it does happen, it's practially impossible to tell whether the data was corrupted by bit rot or by some other mechanism most of the time.
One of the main reason for developing ZFS is actually to counteract the effects of bit rot (if you set it up correctly). Mind you, it's not just about that, as there are mechanisms in place in ZFS which are intended to prevent and repair all kinds of corruption, but bit rot is among them.
Now, whether or not this is something you actually need to worry about is another question. For example, if you have lots of compressed data on your drive:

source
 
This actually happened to this guy (he also describes some countermeasures in that post).
 

I have not been able to find any solid empirical data on this, but I have never come across any credible information indicating that HDDs are not affected by this issue and many (enterprise) storage people saying it is, especially when doing research on ZFS. How probable it is (especially compared with other storage media such as flash, tapes, optical disks etc.) is another question though.  

Depends on how probable it is and how probable something needs to be for you to start being worried. I have so far in 18 months of using ZFS not once had any sort of corruption (of course ZFS can't tell if the corruption was due to bit rot or something else, but still).  

It's what ZFS was made for (among other things). Not that ZFS makes you immune to data corruption, but this is actually one of the express purposes for which it was designed.

You can get some LSI RAID controllers pretty cheap from Ebay. Here is an example, the performance wont be the best you can get but probably more than good enough and it supports RAID 5 and 6. You also need a SFF-8087 to SATA cable. I'm not sure if it is safe to go with cheap cables or not...

http://www.ebay.com/itm/New-Sealed-LSI-9211-8i-SAS-SATA-8-port-PCI-E-6Gb-RAID-Controller-Card-/291219099498?pt=US_Computer_Disk_Controllers_RAID_Cards&hash=item43ce02cf6a

Hey there, @PoLoMoTo!
 
It really depends on what kind of RAID you have set up. 
If you have a software-based RAID, then I think it's possible to transport between the arrays. For example, Windows will ask you to import them and they should be able to rebuild themselves. 
However, if you are using a motherboard RAID controller, the new controller won't be able to see the RAID created by your old one. You might have a chance since both motherboards are the same brand, but you have to check if they have the same controller as well. If yes, you might be able to re-create the array and read the meta-data. 
Another very brave thing to do is set up the new motherboard and controller with the same settings you used in your old array and hope that it will pick up your configuration.
But before attempting anything whatsoever, I'd advice you to backup your array somewhere else. 
Whenever you are migrating, cloning or whatever kind of transporting data you should always do a back up, because the procedures are very delicate. 
 
Good luck! Hope I helped!

Hey Hemanse,
 
just to clear things up, by wireless NAS, do you mean a NAS with no cable at all or a NAS that is not connected to the computer, but just to the router?
NAS generally stands for Network-Attached Storage and are attached to the router via LAN cable and that's it. They are accessed over the network (home or internet) and do not require any direct physical connection to your computer, tablet or any other device. 
The speed basically depends on how you access your NAS. If you try to access it over the internet, your speed would depend both on your home upload speed (since the NAS will be uploading data to you) and your device download speed (since you will be downloading data from the NAS). If you access the NAS in your home network, the speed would depend only on your router's speed capabilities (which are far better than internet's capabilities). Also depends on what you are doing (streaming, file transferring, multiple access devices, etc.) and how powerful the NAS itself is (CPU, RAM, types of drives inside, etc.).
 
If you are looking for something that is not attached anywhere, I could suggest checking out WD My Passport Wireless whick is a portable drive with up to 2TB of storage and can be accessed wirelessly from multiple devices, has a SD card reader and other useful features.

Hope this helps! Feel free to ask if you have any questions

How its a all in one router and firewall package if you have something better why not suggest it as a alternative.

First off HDD's are in the platter sense RAID 0, that's how they get the speed. The spindle spins or spindles, and you have at least two heads per platter, one on the top and one on the bottom. Every write, writes to both heads at the same time much like RAID 0, now with multiple platters it writes across all platters in the same way. This is where the internal RAID ends. Doing a RAID 1 might work but so far to date I have not heard of any company doing this or wanting to.
