  1. I'll be getting my first real server which I want to do multiple things on. I use Windows on all my pc's, but I was thinking of using a hypervisor so i could take advantage of containers/docker etc. Is there any advantage of running a type 1 hypervisor (like Proxmox or Hyper-V core) and then WSE 2012 R2 as a guest OS. DrivePool will run under WSE 2012 and manage all storage. I read a number of other threads on this and it seems drives can be passed thru with no performance hit and even Scanner can work, correct? I was thinking of running the various services I'd need (like media server, download, web server) as Docker containers under Linux. They'd be stored on separate disk of course, and then access the media via \\shares from DrivePool. Is there any advantage to doing this vs - installing WSE 3012 as main OS then using its Hyper-V to host Linux VMs - is the performance same in both cases?
  2. For #2 what I meant is some way to access the file listings using a 2 step mechanism which would maintain a permanent cache, not the in memory caching done by the file system. AFAIK NTFS MFT does exactly this. So e.g. each time the CoveFS driver writes to disk it'd also update this cache, and then listing disk contents could be done anytime without accessing any disk, even from a cold boot. Again it'd be similar to maintaining an index of folder contents.
  3. Sorry for the generic topic and some of these probably are answered in other topics here or the wiki. Does DrivePool have any policies for spin-down or is it controlled by Windows sleep settings for hdd's Is there a way to get file listings without accessing the drive? e.g. in unRaid I read there's a cache_dirs plugin. Would be very useful e.g. when you are searching for files on the pool. I'm guessing something like this could be done very efficiently on Windows by hooking into MFT, the way tools like Everything (from voildtools) seem to do In WHS v1 there used to be a plugin to map drive locations in your pc/drive cages in a graphical way so that when disks fail it would be easy to find them. Does such a feature exist now (this may be a unrelated to DP though) If we reduce the Scanner scanning interval then can we keep the disks spun down for longer periods? And I'm sure this has been asked before - are there any plans to officially integrate snapraid ? It would be a great addition and I'd be willing to pay double the cost for a premium version.
  4. I called SuperMicro, they said the SAT2-MV8 is old and most likely will not support drives >2TB. Since the backplane is also old I am not sure it will actually work. 2 options you listed are - 1. buy 3 HBA's to replace it, like a Dell H200 and then use breakout cables to each drive. 2. buy new backplane which is SAS then buy a SAS HBA with 8087. 2nd one seems cleaner with less cables, and the newer SAS HBA would have better support for things like SMART? e.g. I saw your server has a IBM M1015 which I assume works with no limitations and supports the 8/10TB drives too.
  5. Thanks for the quick reply ! This all came bundled with the server so I'm not sure what to upgrade the controllers to or if its needed. The IBM M1015 (flashed to IT mode) seems popular. If I change the controller I'd need to change the backplane too right - since it has 24 SATA connectors and not SAS. That will get expensive. I got this whole thing for ~300 on ebay and only upgraded the cpu (choices were limited).
  6. Hardware list - chassis: http://www.supermicro.com/products/chassis/4U/846/SC846TQ-R900.cfm mobo: http://www.supermicro.com/aplus/motherboard/opteron2000/mcp55/h8dme-2.cfm cpu: AMD Opteron 2425 HE controller: 3x https://www.supermicro.com/products/accessories/addon/AOC-SAT2-MV8.cfm memory: 8GB DDR2 This is an old server purchased from ebay so the controller is only SATA2. But its pretty popular I think. I will buy DrivePool + Scanner and maybe also use Snapraid. Will there be any issues with this build? I read that some controllers have limited SMART info and may not work with Scanner, is this one of them? Also does this support modern disks of 4-10TB or not?
  7. Just so I understand, DrivePool first matches the folder structure, and then computes hashes of each file to identify duplicated data, correct? So I can have multiple drives with the same folder, e.g. \pics, and when they are added to the pool, DP will then ensure there are 2 copies of the data on different physical disks, and it doesn't matter how many disks the original files were on. e..g. disk 1 - \pics\file1 - 1000 disk2 - \pics\file1-500 disk3 - \pics\file501-1000 When I add all 3 disks, then after hash is calculated, no files will need to be moved, since 2 copies exist on 2 disks.
  8. Well, that makes things simple, thanks!
  9. I'm a new user here, planning my server build and will be purchasing DrivePool + Scanner combo when my NAS is built. Most of my data is already duplicated which I manage manually using external hard disks. e.g. disk1 - \data \docs \movies_backup disk2 - \data_backup \pics_backup \movies disk3 - \pics \docs_backup I'd like to add these disks to DrivePool so that it already knows where the duplicated copy of the data is kept, and so doesn't have to duplicate it initially (since that'll be am expensive step). After that of course I'll let it manage the duplication part. I'm ok with changing the folder names if needed. Is this possible? Also is it possible to keep some of the duplicated data on external drives, and have the duplication run once the drive is connected?
