  1. Another victim here... However, i feel like i've noticed it get worse over the last few months. The VM has more resources that my PC has, yet performs like my celeron dual core! I have a new server here awaiting time to upgrade, strongly considering VMware hypervisor and then virtualising unRAID so i can get some performance to this VM. My Crystals below for ref - they seem alot higher than those i've seen here, but they're stil ridiculously slow. Edit: Setup is raw passthrough of SSD via unassigned dev. and /dev/disk/by-id/
  2. Hi Raiders,, I recall passing through someones storage forum, and briefly glimpsing a comment advising purchasers away from buying the much cheaper Chinese held controller cards, HBA/Expanders. At the time it was of no significance to me, it wasn't what i was lookking for at the time so i moved on. Well i need a SAS expander - Where one can be had from HP or IBM for $20 New..... Even their Intel expander iis quite affordable. Are there known ongoing issues with these imported, assumed "cloned" cards? Or a handful of cases anda bit of Russian Roukette? Would you use one? (*Everyone screams NO IT'S YOUR DATA HERE*) Unfortunately this is an unforeseen expense, and finances are never good anyway, but i came to purrchase a new (used) IBM x3950 x5 for a vvery good price, which means those big old disks have got to go somewhere! Enter External SAS enclosure; -Gen8 Microserver gutted of majority of internals (everything but the wall) -Replaced drive bays with a 5 in 3 cage -Had some SSD mounts 3D printed She;s coming together beautifully, but build is earner completion, and i need to get that SAS card in there so i can enjoy my Penta-CPU 80 core beast in action! Insert other media Ni suggestions ignored! Thanks, Nash
  3. Might be a stupid question.... But can i use a GPU mining PCIe riser board to power the SAS Expander? I don't see any reason why not....
  4. Seems pricey compared to everything else, however it's also the only one i've seen with an independant power input which is a BIIG plus. Thanks, assumed as much, but wanted to ask whilst i had the chance! 8088-8088 cables, already sitting in my cart Well there you go, most interesting piece of information i've learnt so far! That's nifty. Ah ok - I might go without, no need to turn it off regularly enough to need a power button, and that way it's hidden from prying fingers. If i do find the need, i'll whip up a board of my own. So i know exactly what i'm doing now, i just have the issue of sourcing a local SAS expander, and also the price of the Intel SAS (considering this was not budgeted for), i certainly want to avoid requiring a motherboard etc... So i need to prey i can find one 2nd hand in the forums, a bit cheaper, and local! Thanks again for your time and expertise johnnie, greatly appreciated! I've wandered these forums long enough to know that you're one man who knows his sh*t, so i know i've got trusted information and probably the best available!
  5. Firstly johnnie, thankyou very much for your assistance and your patience. This concept was foreign to me, and i've learnt alot, but you put up with my misunderstanding, and nudged me in the right direction. Just a few questions to finish off, and i should be out of your hair. I know the solution design now, i just have questions about parts Made some notes on the img to ensure i understood what was going on. Ok, so i wont be going the HP route. Upgrading my hardware, i don't want to go backwards with the expander. So what affordable SAS expanders should i look at, that wont have an issue with unRAID? Just had aquick look on eBay, looks like the only expanders in Aus are HP's! Is the IBM 46M0997 ServeRAID Expansion Adapter 16-Port SAS Expander sufficient? IBM will ensure compatibility with my server... From image: What expander is in use in the photo? Is that molex power an addon or part of design? Those PCI boards, what exactly are they called? The SAS Expander is taking input from the HDD's, and also outputting - Are there designated ports on the card for input/output? Or is it a feature of an expander that it can detect inputs/outputs? What's the role of the SuperMicro board, and can they be purchased individually? Name/model? It necessitates the need for a motherboard correct?
  6. So option 2 i wouldn't consider - As you said, vulnerable, and 1m limit will make things difficult or impossible. I have an HBA in the server, with external ports, so i assume you are saying i need a SAS Expander in place of my M1115? Can you give some examples of a SAS Expander that has both internal and external ports? I was unable to find anything on eBay with the exception of a SuperMicro UIO card.
  7. This is why i am here - I had assumed that they could communicate across the PCIe BUS. Ok, so that setup does not work. So i need an HBA with internal & external ports in the enclosure (Examples of such?, i couldn't find anything i'd trust to work on eBay)?
  8. In future, if expansion beyond 8 disks, i would replace the M1115 with a SAS expander and some more breakout cables right? As in this scenario, the M1115 is playing the role of the "SAS Expander", if i understand correctly....
  9. H200E External on the server.... And i am connecting from the HBA (M1115) directly to the disks with breakout cables, inside the enclosure. Do i need an expander if im using an HBA with breakout cables to direct connect? My understanding, an expander would allow me to run 16/24 disks without altering the hardware?
  10. Hi all, External storage is a bit new to me, but i've been absorbing as much as i can, as i need to implement a solution (as cheap as possible, because this cost was not planned for) next week at the earliest. I'd like to confirm my understanding and if i've understood right, awesome! If i've got it wrong, i look forward to having a config specific to me, critiqued. So, inside the enclosure we have 8 3.5" HDD's. Would i place an IBM M1115 (i already have this, so more cost effective to reuse than but an 8i8e card) with 8087-Sata breakout cables connect the HDD's to it. Would i then also add a Dell H200E 2x External SAS inside the enclosure, to allow me to connect the enclosure to the server. (using 8088-8088 cables?) Inside the server i add another H200E External SAS to accept the connection from the enclosure, and that is all that is required in this scenario? Rudimentary ASCII Diagram of proposed configuration.... __________________________________________________________________________________________________ / unRAID Server(H200E)-----------(8088 Cables)----------| (H200E) | |---Enclosure (mATX MB, Celeron, 4GB, USB Boot Linux OS) | | (IBM M1115)---------(Breakout Cables)-----------(4x 3.5" HDD's (x2)) \ __________________________________________________________________________________________________ If the above is all correct, what are the computing requirements of the enclosure? Obviously i need a MB with 2 x8 PCIe lanes, but is there anything else i need to consider? At present, to keep costs down i'll be reusing a mATX motherboard w/ Celeron processor & 4GB RAM for the Enclosure 'brains'. Is there some sort of affordable Single Board Computer that is commonly used for this task that requires no OS? Appreciate any and all feedback given Thanks in advance!

  11. Thanks for letting me know - I came to much the same conclusion myself, i was unable to see anything so thats when i call in the cavalry! PSU is brand new (installation preceeded the VM creation by weeks) - Doesn't mean it doesn't have a fault of course. I am powering a number of devices off only 2 SATA rails, but certainly nothing that would overload any aspects of the PSU. All said and done, absolutely everything else works fine with the exception of this quasi-VM. I suspect that between the block level SSD passthrough, GPU passthrough, and the fact i plucked an SSD from a PC and booted it into a KVM environment - one of them is throwing a fit, but nothing indicates an error. It just occurred to me that i can remove the GPU passthrough as a test measure before resorting to a reinstall - That will at least rule that out any GPU quirks, as it's still not a perfect science (unsafe interrupts needed enabling, i'll remove this with the GPU). I'll report back if for nothing more than trying to see this through to resolution. From there if issues continue, a fresh installation onto block level storage and work my way back up from there. Process of elimination sucks!
  12. So, it wasn't the USB controller - had 2 lockups since removing it Seeing as no help is available, i guess i'll have to attempt partitioning the SSD and installing a fresh copy and trying my luck
  13. Did it leave any footprints, or you traced it to USB via trial and error? It seems to becoming clockwork like, so i'll know pretty quickly whether it's the USB card or not so i'll give it a shot. Cheers, Nash
  14. Bump - Anyone willing and able to assist please?
  15. Ok, my original theory is debunked... Parity check is still running and the VM locked up. Latest diagnostics file attached. yoda-diagnostics-20180916-0725.zip
