I'm at work now so I'm not 100% sure on vt-d. I know it's enabled on my mb and I swear I saw it somewhere. I will double check later. Also I have read that it is/can be enabled depending on the Es revision. For each Es chip their are several revisions that go out. So it may be some are and some are not enabled.

FYI from the link you posted I thought you could like to know that you can't run dual 1660's. That chip only works in single cpu configurations. I also wanted to run that same setup. Op, I have a recently purchased E5-2670v3 es that has a stock speed of 2.2ghz. I have just been running stock win10 on it. I have steam on it but I have only streamed games from one of my other computers. I'll load up some crysis 3 tomorrow after work and let you know how the performance compares to my 5960x computer and my 8350 computer. If it runs on my 2.2 chip, yours should be fine.

What exactly is a parent / child share, and what is your goal in creating one? (I ask because there might be another approach that does work) Having one share that I can mount on 4 computers, which is read only for everyone. So the parent share can be documents (read only), then under the documents share, I can have different shares for different users. One for me, one for my brother, one for my mother etc, which is read/write for the correct user and nobody else have access to that folder. Then I would not get so many network mappings, and it would look a loot cleaner. I'm struggling to understand your description of what you want to achieve. When you say "I can have different shares for different users" do you mean "I can have different folders for different users"? In which case everyone mounts a single share called "documents", which contains three sub-folders "me", "brother" and "mother", to which only the relevant user has read/write access and everyone else has no access? That can be done but not via the GUI. But it doesn't use child shares so maybe it isn't what you want. You'd need to add the three users and their passwords via the GUI and create the documents share (making it private and allocating your required permissions to it) then switch to the command line and use chown and chmod to achieve something like this: root@tower:~# ls -l /mnt/user/documents total 1234 drwx------ 1 brother users 32 Apr 25 23:50 brother/ drwx------ 1 mother users 32 Apr 25 23:51 mother/ drwx------ 1 me users 32 Apr 25 23:52 me/ root@tower:~# EDIT: Having said that, I can't work out the advantage of this approach over one with three private shares called "my documents", "brother's documents" and "mother's documents". I think the benefit of his idea is that when you look at the root Unraid share you can see a documents share vs individual user shares or hidden shares. That way it is easier for novices to find their docs and keep the structure clean. I have also wanted to do this for this exact reason, I didn't know you could do it within the cli. Although I have it configured through AD so it's now moot for me, but I'm definitely saving this for future reference.

If you still don't have the mb, cpu, ram sold I'll buy it all.

Does/would this proposed notification show up for beta versions? I just worry that having the word recommended in there may steer people to installing an update without reading the release notes which warn them about potential bugs or data integrity issues. If I was a fairly new user, or someone who didn't frequent the boards very often I might read that update notification as a recommendation from LT to upgrade, possible from a rock solid stable version for me, to a beta version. Just a thought I had.

A note about just pulling the plug out of the wall. I think I remember something saying it can cause some ups systems to shut off if they don't detect a ground state. So that may or may not work. I would try it first with nothing plugged in so you know it won't just shut off if you pull the main plug.

I have a domain set up in my network and have folder redirection configured this is basically the same thing I think your trying to accomplish. I know there are some difficulties when the folder your moving a is a part of a "libraries" collection. As you said, index also presents issues. Also I don't know if you use Steam but I do and I have had issues with several games that done support unc file paths. This cause games and potentially programs from not being able to save information correctly to places like the documents folder. I think your better off not redirecting them to shares. Just my 2 cents.

I can't really speak to a direct clone. I know that some users use cron to do scheduled backups of the array data to a second unraid box. I don't know about dockers or vm's.

Too true. I would totally agree. Which is why two weeks ago when I was the best man at his wedding my toast was scathing. J/k

I hope you pushed him down some stairs... I'm only half joking. I would have loved to, but he didn't really think it would be a problem. He was sick and trying to sleep on the couch and the server was in the living room temporarily. So in his NyQuil addled state he just unplugged it. Ouch

I also discovered this, after I purchased the drive. Oh well. I have about 30TB of media and the rest is computer backups, programs and documents. So even if the media isn't compressible I can back up the other stuff hopefully with compression. If I lose the media that's ok. I can just re-rip most of it, as time consuming as that would be. I would be happy to just have a backup of my other non media stuff. Even without compression I can back up the whole thing for about $544 in on 17 tapes.

Speaking of tftp and pxe I bought serva64 to pxe boot my computers and I love it. Installing my OS's over the network is amazingly fast. I keep it running all the time on my server just incase I want to reinstall any machine. If it could run in a docker that would be sweet. I have seen the fog project around for a couple of years. I even built a fog server once but I didn't spend a lot of time using it. Form what I saw though it was an excellent piece of software. Though it really shines when your doing a multicast rollout to many computers at once.

So I have been on the fence for a few weeks over whether or not to buy a tape back up solution for my unraid. I have 11 4TB drives with mostly media and computer backups. I also use it as a backup of my works SCADA system and our sql database(I'm a Water Treatment Plant Operator). Currently I have no protection at all. I'm running these drives on a Server 2012 computer using StableBits DrivePool software. I migrated to this from UnRaid as a temporary measure after my roommate unplugged my older 15 2TB Unraid server during a parity rebuild (because it was making too much noise). After coming back online with many problems and needing to replace over half of the drives I decided to build a new sever with 4TB drives. Well this temporary server has now been running for almost 18 months with no protection. I know I know, bad idea. So know I'm ready to begin the process of migrating back to unRaid. UnRaid is not a backup solution, and I made a choice when looking for other options as far as backing up my entire array. Most of my files are media, and follow the basics of WORM. write once and read many. So I was trying to decide if I wanted to build an entirely separate Unraid setup. It seemed to me having two complete copies of all of my data and parities was redundant. At least as far as two computers, Two sets of all my hdds. Not to mention that when my array grew I would also have to expand my backup. Another issue I foresaw was having both servers in the same house. While we don't have any real chance of flooding (I Live on a small island) we could have fires (been through that once already, lost everything) thefts, earthquakes and other natural disasters. So having the backup server in a separate geographical location would have been ideal. Yet my internet is aDSL and my upload is around 50kbps. So that's out. So I had to come up with another solution. After weighing the pros and cons I finally settled on a tape backup system. A quantum LTO-6 tape drive. http://www.backupworks.com/quantum-LTO-6-Drive-internal-bundle-TC-L62AN-EZ-C.aspx THE PROS:: Massive storage size per tape. Up to 6.25TB. Reasonable speed writing from my consumer grade HDD over my gigabit nic. Cheap media ~$34-45 per cassette. Tape medias long storage lifespan. THE CONS: Incredibly expensive initial cost. (At least for me) $2000 bucks. I could buy 14 4TB drives for that. File management and de-duplication. PITA to do incremental backups (I have no real experience with tape backups so I could be wrong on this. My first and last tape backup drive was 15 years ago when I was in high school). So, I have decided that when I migrate my data to the new UnRaid server I will fill each drive as much as possible (leaving some headroom because I remember from somewhere that UnRaid likes about 10% free space on all drives or performance suffers). With most of the data being static WORM I can then make a backup of it to tape (hopefully encrypted though again no experience). Then I can send the tapes to a budy of mine who lives a few miles away on another island. With the tapes being small and relatively cheap it should be a problem to make a complete backup and store it. My largest gripe is with the cost. I was on the fence for a while. But yesterday I made the purchase and now I can't wait for it to get here. I'm worried that now I have a viable backup strategy my disks are going to fail before I can copy them. Ha. As far as the cost goes, I'm hoping my work will help cover the cost as I'm thinking that once I'm done with my initial backup, it may take up a more permanent residence there to backup our mission critical stuff. Our IT infrastructure at work is abysmal. My home network is larger faster and better protected from disaster then my work is. This maybe a great solution to my storage needs and I just thought I would share my experience so far. I don't know of too many people using something like this along side UnRaid so I am hoping there is some interest. I'm curious if anyone has thoughts on this. Have I made a huge mistake or was this a good choice? -Alex

I also like the idea of dual parity vs multiple smaller arrays. Hard drives are only getting bigger, so even if we break down the array in to multiple smaller ones the mtbf rate becomes more and more prevalent. You could argue bigger drives and less of them, but with today's multimedia edging into 4K my 11 4tb disks would be filling up fast even if they were 8tb disks. If I have the space I'm filling it I have an unused pro license and I would still be willing to pay an additional license fee for dual parity. I can certainly understand the hesitancy of needing royalties and lawyers and the big mess that entails, but I think it would be worth it. Just my 2 cents.

568A or 568B shouldn't matter as long as all devices are wired the same. Most installers that I know including myself use the B method. But it shouldn't make a difference really. A is more common in residential and B is more prevalent in commercial applications. The modems line to the patch panel should be electrically similar to the other lines. So in your case 568A. Make sure that both ends of the cable are wired the same. That should do it. Does your modem have dhcp/ switching functions? Some modems will only output one ip to one device.

Ok I'll start the return process. That is very disappointing. I bought these drives to start moving over my current 40TB windows 2012 drive pool. I was really excited to start work on it as the preclear a took about 100hrs. Oh well. Better to find out their bad now then when they have data on them. Thanks Archedraft for the help.

So I just put two new WD-4TB drives in my HP N40L to prelcear. I ran both drives through 3 cycles of the preclear script. One drive had no issuse, yet the other one had a few. I'm posting the Smart report for the drive in question. ================================================================== 1.15 = unRAID server Pre-Clear disk /dev/sdc = cycle 3 of 3, partition start on sector 1 = = Step 1 of 10 - Copying zeros to first 2048k bytes DONE = Step 2 of 10 - Copying zeros to remainder of disk to clear it DONE = Step 3 of 10 - Disk is now cleared from MBR onward.

Assumption correct I was speaking of the pro license. Ah the release notes, I have yet to pull down UnRaid 6 so I missed that one. Ah 25 is the array limit. Could not remeber if it was 25 + parity or 26 or Cache as well or some combination. Thanks

Hello people, I'm starting my new build and I had a quick question. Is the 26 drive limit still related to UnRaid having /sda -/sdz id's or is the limit only imposed upon the array itself? I ask because I watched jonp's video on cat5.tv last night (nice job BTW) and I really want to get back into UnRaid. I currently have a Norco 4220 and 2x 16 bay DAS enclosures running on my current Server 2012 storage box. I would be happy with 26 storage drives in my array (which I'm not close to reaching yet) but I would like to use my DAS boxes for docker and VM drives. So I could easily go over 26 drives when I start adding my VM drives. Thoughts?

I think I've seen this before. If I remember correctly, one is reported you instantaneous speed and one is the average so far.

mIRC. I'm brand new to IRC though.

Good point about the cpu. I like the extra head room with the extra cores. I don't run crossfire or SLI so I'm good with just two graphics cards for the gaming VMs. One small card for the media center. One external hba for my das case and maybe if I can fit it a pcie sound card.

I'm seriously considering using this board with the new 18 core e5 and replacing my 2 gaming machines, my xbmc computer and both of my UnRaid boxes. Unfortunately I don't know jack about VMs but having it would give me plenty of incentive to learn.

Ok. If that's the case you should just be able to search google for a SFF 8484 reverse breakout cable. Hope it helps.

Are you sure it's a SFF 8484? It's probably a SFF 8470. In which case you would need a reverse breakout cable. See http://lime-technology.com/forum/index.php?PHPSESSID=708aee56dfa77a71c223ae5f4878a917&topic=7003.0 for more details.
