  1. Thanks for links, that's very helpful. In summary it sounds like SSDs will work, however TRIM is not currently supported. So I can either wait until trim is supported, or rely on the SSD inbuilt garbage collection. The data wont change much and there will be alot of idle time, so will consider giving this a try. To help mitigate risk, I assume there is no harm in running more frequent parity checks (say weekly), to check there are no parity corruption issues (as well as updating my offsite backup).
  2. Hi all Is it possible or sensible to use an SSD as a data disk? Since SSDs are getting pretty cheap, i think it would be nice to have some storage on faster SSDs which would be useful in many scenarios where access time lag is noticible, things like reading metadata and loading thumbnails of images etc, plus I'm sure there are many other scenarios which would benefit. Also I assume that "spinup" is almost immediate on an SSD? I know SSDs can be used as the cache drive, but I would like the data to be protected as part of the array. So questions: Will it work? Are SSDs reliable enough yet or am I asking for trouble adding it to the array? Will the risk of multiple drive failure effectively be significantly higher? Is there issue with trim not being supported in reiserfs? would moving to another supported filesystem resolve this for data drives? I have a Crucial BX100 250GB spare I am tempted to use for this purpose. Another option i have considered is having the data on normal hdds in the array, but add the SSD (either as a cache or seperately mounted), and rsync the data to the SSD to keep in sync, then add an additional samba config for the SSD. Any thoughts? Thanks, Jake
  3. I'm pretty happy with the board so far. I still have a monitor plugged into it so not tested the ipmi that much and have never used supermicro ipmi so can't compare. It works, though once I did have an issue where the keyboard input wouldn't work through the java viewer.. I've managed to get pci passthrough working with a couple of vm's in xen after upgrading the bios (the bios update didn't mention anything regarding vt-d but graphics passthrough would crash within a minute or so before I did the upgrade). Biggest issue I have with the board which i didn't realise before buying is that the sata ports are at right angles on the edge of the board which gave me some issues with the case I have (x-case rm 424s). Finally, I have an issue where the bios for my two aoc-saslp-mv8 cards when both plugged in with drives attached hangs on booting, after a couple of minutes it times out and will continue booting into unraid, and drives work fine so just a bit of an annoyance. I have followed the post on the controller card forum board to disable RAID functionality in firmware .21 but this hasn't made a difference. Hope this helps.
  4. Ordered the following: Asrock E3C224-4L - thought I might as well have the extra LAN ports and IPMI was a must have, ruling out the C226 WS Intel Xeon E3-1245 v3 - I know the graphics will be redundant on the system, ordered this over the 1230 mainly because it was in stock now (UK) 2* Kingston KVR16E11/8 8GB DDR3 1600Mhz ECC Corsair RM650 Gold Xcase RM 424s Jake
  5. Ah you're right, E3C224-V+ does not have IPMI, thanks for pointing that out! So I just need to decide between E3C224 and E3C224-4L. Not sure I can think of a good use for 4 lan ports, even with virtualisation with xen. Jake
  6. Does anyone have any experience with this motherboard with unraid? Also, does anyone know if it is compatible with VT-d? (I plan to use a xeon e3 1230 v3) http://www.asrock.com/server/overview.asp?Model=E3C224-V%2B for a little more there is also a version with 4 LAN ports (http://www.asrock.com/server/overview.asp?Model=E3C224-4L). I am considering it over the Supermicro X10SLM since it has an extra PCI 1x plus two extra sata ports. I am also considering the Asrock C226 WS, but sadly this lovely board doesn't have IPMI otherwise would be perfect (http://www.asrock.com/server/overview.asp?Model=C226%20WS) Any thoughts? Thanks, Jake
  7. Thanks, I'll keep looking for 1600, but everything I have found so far in UK is quite a bit more expensive.
  8. Good point about hyper threading, if I can find somewhere that stocks it in UK, will go for that. How picky are supermicro boards with memory, will the kingston 1333 ECC value ram work?
  9. It's time for an upgrade, I have been running my current setup for about 5 years and I would like to upgrade my Motherboard,Processor and RAM. Requirements are: IPMI - This is a must VMs - I want to be able to run virtual machines in Xen, Passthrough for graphics cards would be a bonus. I'm in the UK and my budget is ~£500 I am currently looking at the following: - CPU : Intel Xeon E3-1220 v3 ~£155 (http://www.scan.co.uk/products/intel-xeon-e3-1220-v3-s-1150-haswell-quad-core-31ghz-base-35ghz-turbo-8mb-cache-80w-retail) - Motherboard: Supermicro MBD-X10SLM-F-B ~£140 (http://www.xcase.co.uk/component-parts/supermicro-motherboards/supermicro-mbd-x10slm-f-b-socket-1150-e3-xeon-v3-i3-micro-atx.html) - RAM: Kingston KVR1333D3E9SK2/16G 16GB 1333MHz CL9 DDR3 ValueRAM ECC Memory Kit ~£120 (http://www.amazon.co.uk/Kingston-KVR1333D3E9SK2-16G-1333MHz-ValueRAM/dp/B0064R7LH8/) I am hoping I don't need to upgrade my psu (Corsair VX-450W) Questions: - Will the Kingston Value Ram work with the Supermicro motherboard? - Does the CPU/Motherboard support passthrough with Xen (ie if I want to create an xbmc VM)? - Will my existing PSU (corsair VX-450W) work with the Motherboard/CPU? My existing setup: - Case: CoolerMaster Centurion 590 - PSU: 450W Corsair VX450W Power Supply - MB: Biostar TA690G AM2 - RAM: 4GB - CPU: AMD Athlon 64 LE-1620 CPU - Controller: AOC-SASLP-MV8 - Drives: 12 assorted drives, mostly low power (20TB usable space) Any thoughts, comments or recommendations? Thanks, Jake
  10. Update on the xbmc front, looking good: http://www.raspberrypi.org/archives/571
  11. From what I understand it can do 1080P hardware decode at 30fps, so I think that puts 3d out of the question. I also was under the impression it wont be able to 5.1 (or 7.1), but I'm sure all will become clear in time. I was thinking these would be perfect for secondary media players for bedrooms, kitchens etc.
  12. I think I read somewhere that power usage on one of the alpha boards (under load with graphics) was arround 300ma with a 9v supply so I make that at under 3w. Definately an exciting project, I really hope xbmc is successfully ported and optimised for the board.
  13. I now have the card, and can confirm it works with the BioStar TA690g.
  14. Motherboards and Unraid aside, will controllers need to be compatible with these? (specifically AOC-SASLP-MV8)? I ask as I am looking to upgrade to one of these controllers soon, but just wondering if they will be useless with 3TB drives, meaning later on I would possibly need to upgrade Motherboard and controller?
  15. At the moment it is not too bad, I have 4 drives on the motheboard (1.5tb Parity, 750gb, 750gb, 1tb), 4 drives on the first PCI card (500gb,1tb,1tb,1.5tb), and 2 drives on the second PCI card (1.5tb, 300gb (not part of the array)). It takes about 20 hours to run a full sync, though I do realise I could probably reduce this by rearranging the drives such that the larger drives are on the MB ports. I don't remember how long the last pre-clear I did took, I get the feeling it was arround 24 hours for 1.5tb, but really can't be sure. The issue I have noticed, is that if I want to transfer from one of the PCI HD's over the network I only get 30MB/s, where as the MB drives are faster. I imagine by the time I have filled the second PCI card performance will really suffer, especially on a parity sync.
