  1. If you need anything from me - eg measurements etc just let me know and I'll provide.
  2. Gaz, that's funny 'AS' - 15 mins ago I just ordered 3 of them!!! I felt, as you mention, that the exisiting holes in the cage are adequate enough with my custom skirt. http://cplonline.com.au/index.php/noctua-nf-f12-pwm-120mm-1500rpm-pwm-fan.html
  3. Can I ask what the driver is for this preference?
  4. UPDATE!: As some of you may know following my other thread about the Seagate 8TB HDD's I have recently purchased (and as I mention in this thread earlier) I have been pre clearing like a maniac for the last 5 days with three disks in in the DS380 and as such testing the cooling capabilities of the case. I reported above that I was experiencing temps for disk1, disk2, disk3 of: 37C, 40C, 35C. After about 50 Hours of continued use in a pre clear those temperatures rose by a degree or s (worst case) and were sustained. While I agree with Garaycase that if I can sustain those temperatures I am well within Manufacturers Operating Temperature Spec's I thought - can I improve them - at very least give me headroom for increased temperatures due to additional disks in the future. For the purpose of this thread (ONLY) I was fortunate enough to have a Power Cut mid pre clear cycle 2 so I had to restart. So for redoing cycle 2 I only run 1 cycle so I could have a look at the reports and not wait for 3 cycles to finish. Anyway .... last night when cycle 2 finished I decided to explore a mod to the case (sort of) that came to me. I was thinking at work - how do I ensure the air from those fans goes over the drives??? STEP 1: I am looking at putting an aluminium plate between the fans and the motherboard and STEP 2: drilling holes in the drive cage on either side. The idea is to restrict air going into the main part of the case and just being evacuated and "forcing" it over the drives as well as increasing the exposure of the drive to the air by creating a little compartment of sorts where the fans are installed so the air can ONLY go over the drives. I completed a prototype of STEP 1 last night using cardboard from the side flap of the cases' box cut exactly the size of the gap between the cage and the edge of the fans sitting just on top of the small gap between the motherboard and the drive cage. If you can picture it the drive cage itself sits on the cut out thus applying a bit of pressure between the cage and the side of the case and thus keeping it in place (for now as its just a prototype). Tools for this little Prototype: From the Top of the fans: From the Middle of the fans From the bottom of the fans: *Sorry the pictures are so poor - due to case design this is the best I could get from in or out - but as you can see the cut out goes from the top to the bottom of the case creating a sealed compartment where the fans are from the rest of the case pushing air over the drives and then over the board and CPU and then out the back* The ambient temperature with all disks spinning after half an hour was 27C which I am happy with. To give me a real world example I cranked the heating in the house to 27C to make it as warm outside as inside the case and I started a third pre clear. I checked for 10 mins that things weren't going to increase to an ridiculous temperature and when satisfied that my concept was at least not going to do a destructive job on the drives, I went to bed. This morning, I am pleasantly surprised: Preclear is reporting (after 7 hours of continuous use) disk1, disk2, disk3 of 37C, 36C, 34C (Also noteworthy IPMI reports that the Motherboard and CPU temperatures are 39C, 38C). At very least I seem to have been able to "improve" the airflow and not make it worse. In addition keeping the temperatures under 40 is nice! :-). I don't know if things will improve if I switch from cardboard to Aluminium? I am also wondering if I need to bother with drilling the holes. Anyway, lets see how they stand after the full 50 hour cycle 3 pre clear is done. Will update.
  5. Cycle 2 has just finished (glad I executed it separately so I can interpret the reports before starting Cycle 3 - given I don't have reports for Cycle 1 due to the Power cut :-() and I have some data. No power cut this time!!! S.M.A.R.T reports at the beginning of cycle 2 are clean. No logged S.M.A.R.T errors and no Current Pending Sectors or Reallocated Sectors. Seems disk 1 is doing ok - but I have S.M.A.R.T errors and sectors were pending re-allocation after pre-read on disks 2 and 3. The Question I am asking myself is - are these errors and pending sectors due to the power cut and the disks are ok (I note that there are no reallocated sectors), OR are they showing signs of a DOA drive? I have started another cycle (cycle 3) on them anyway as a matter of course but can someone help me interpret these cycle 2 reports please? FULL S.M.A.R.T reports attached.

  6. My understanding is that this is correct. No reports, the preclear hasn't finished.
  7. Im assuming you can VPN into your local network as I can't imagine anyone exposes telnet sessions to the Internet these days. If so - if your box has the X10SLM-F board in it as per your sig why don't you vpn into your network and then (either via rdp to local machine or ssh tunnel perhaps) use the IPMI web interface and attach yourself remotely to the console session and change to the relevant tty to have a look!?
  8. Unless there is something wrong with preclear, there should be no pending sectors. Preclear writes zero to all locations. That write would remove any pending sectors. A write to a pending sector is reallocated. Any pending after that write would be a red flag. The potential for data loss exists with power cuts on any drives with write cache enabled. The contents of the cache could be lost prior to the write to media. This is true for both PMR and SMR drives. As WeeboTech mentions, the data during preclear is zero, thus not a concern. Even with the power cut, normal rules for returning the drive should apply. If there are pending or reallocates during a preclear, best to deal with RMA now. Thank you for your explanation of the explanation!! I needed it! LOL!
  9. It could leave sectors in a poor state, thus leading to pending sectors. Also if it was in a band write, who knows what was lost. For a preclear it may not matter as you are always writing zeros. For real data, this could cause quite an issue. It was just going through cycle 2 of a pre clear. I am sorry I need to dig further into your response as I don't understand. Normally after a pre clear if I got ANY pending sectors i'd return the drive DOA. Are you saying that now there was a power cut mid preclear that I could reasonably expect them?
  10. I CANT believe it! Going through cycle 2 and I have a Power Cut!!!!!!!! I don't even know what to do now! Start all over again with 3 cycles. Just do 2. Jeez. First of all - walk away from computer before I throw it though the window of the 10th floor! EDIT: Nothing for it. Started again. This time only 1 cycle. For kicks I did a S.M.A.R.T report of the three drives after 1.5 preclears. Sigh. 20150405_SG8TB_ERR_Disk1.txt 20150405_SG8TB_ERR_Disk2.txt 20150405_SG8TB_ERR_Disk3.txt
  11. Which version of the pre clear script did you use? I updated my post with figures for Bjp's script.
  12. Hi All, Well I guess the topic says it all. As I look into Virtualisation on v6 I realised there are two ways to go. KVM or Xen?? I have to wonder why LT implemented two methods of virtualising on v6. I mean why not go with one and then at least everyone is heading in the same direction too! Obviously LT is pushing the use of Dockers - but of course thats only for Linux based applications. It "appears" (to me at least) what Xen seems to be "favoured" but I still don't know. Do we now have an idea if one is going to be phased out in favour of the other? I'd be interested in any opinion! Daniel
  13. The WDIDLE3 utility will only work in a DOS environment. You need to create a bootable USB stick, and stick a copy of WDIDLE3 on it. The following link has a method for creating a bootable USB stick you can follow. http://www.bay-wolf.com/usbmemstick.htm
  14. I just glanced at a past post to get an indication of your build. If you're reffering to the setup you have with the Supermicro X9SCM-IIF-O board you have IPMI. Why don't you use that method to run preclear rather than telent/ssh/screen. It's essentially like you're at the console itself - your browser uses Java (or similar) to attach itself to it and display it like you were sat in front of it. If it disconnects you just log back into IPMI interface and attach yourself back to it. Easy peasy.
  15. Perhaps. Remember to post your mods when you are done. Just in Case! Anything's possible, but I really doubt that you'll have any significant problem with temps. The Lian-Li PC-Q25B has similar airflow, and the temps with 3 drives vs. the temps with 7 drives when I fully populated the case were not appreciably different (perhaps 1 degree higher on the upper drives). I think you are right. As I noted in the other thread about the Seagates - I am also thinking that the high temp experienced on the 2nd drive is due to it being a bad drive. It is now running at 42C and the others 39 and under after a whole day of operation - BUT what makes me think it is bad is that it has dropped behind disk 3 in the % complete even though it was started a few mins earlier. I don't think it should have. Time will tell.
  16. No worries. Think I have a bad drive in there though. Disk 2 (which incidentally is the one running hotter than the others @ 42 C over disk 1 39C and disk 3 36C) has dropped behind Disk 3 in % complete as reported above. :-( Lets see anyway.
  17. Perhaps. Remember to post your mods when you are done. Just in Case!
  18. I think you are right. They are all sat at 99% now for Cycle 1 of 3 pre read and they are at: Disk 1 (Top Bay) is reporting - 38 C - Preclear Running Time: 19hrs 41 mins Disk 2 (Second Bay) is reporting - 40 C - Preclear Running Time: 18 hrs 32 mins Disk 3 (Third Bay) is reporting 35 C - Preclear Running Time: 18 hrs 27 mins I think they are working out MAX now and I doubt the rest of the preclear script is going to increase the workload considerably. Time will tell over the next 3 days and I will post updates BUT I think the fan config is more than fine and I don't intend to tweak. Interesting that the middle bay of the top 3 bays has a higher temp than the others. I don't know what is causing that - maybe the drive itself - maybe the case design - maybe combination of all that plus components - who knows. As you mentioned in your earlier post I half expected the top one to be the hottest. Whatever way I think I am happy. This is a great case. P.S. I feel I am going to have to just keep an eye on things as I add more drives though - but thats nothing new.
  19. As you can see as the months have gone on and more discussions have been had I have changed my mind on the Backup Server MB and CPU options. As I note above I have gone with the ASRock C2550D4I Mini ITX Motherboard with the integrated Intel® Atom™ Processor C2550 in it. It was actually another post by you which got me looking into this board and CPU and I liked that it was passively cooled. Once I was sure that the issues with it were over (which I am) I decided. I have also thrown 4GB (1x4GB), PC-12800 (1600MHz) ECC Unbuffered DDR3Lin there. You were also VERY right about the PSU for the Backup Server. Thank god for that bit of advice. I went with the 450 (Gold version for Modular too) and am very happy! Thanks for the EXCELLENT guidance!
  20. Your point is well taken. I have updated the thread considerably and updated the Status.
  21. This is consistent with that I am seeing. All 3 of mine which are running through their pre read of cycle 1 of 3 at the moment (about 78%) are running at about ~121MB/s. Pre read figures: UPDATE 1: All three at about 91% of the preclear pre read of cycle 1 of 3 and are running at about ~100MB/s. UPDATE 2: All three at about 99% of the preclear pre read of cycle 1 of 3 and are running at about ~85MB/s. UPDATE 3: All three at about 100% of the preclear pre read of cycle 1 of 3 and were running at about ~80MB/s. All three completed their pre read with a FINAL speed at 100% of ~80MB/s taking 19 Hours 57 Minutes. All 3 of have started running through their zeroing of cycle 1 of 3 at the moment (1%) and are running at about ~200MB/s. Copying Zeros figures: UPDATE 1: Drive 1 & 3 at EXACTLY 40% and 30% respectively done of the preclear zeroing of cycle 1 of 3 and running at about ~ 185 MB/s. Drive 2 has called behind and at about 28% but still reporting 185 MB/s. ** UPDATE 2:Drive 1 & 3 at EXACTLY 59% and 50% respectively done of the preclear zeroing of cycle 1 of 3 and running at about ~ 175 MB/s. Drive 2 has continued and not fallen further behind at 49% and reporting 175 MB/s. ** UPDATE 3:Managed to catch all drives at 100% done of the preclear zeroing of cycle 1 of 3 and running at about ~ 138 MB/s. Drive 2 had continued and not fallen further behind (as above) and was reporting 138 MB/s too. ** All three completed their zeroing with a FINAL speed at 100% of ~138 MB/s taking ~16 Hours. Total Time for cycle 1 so far is ~36 Hours. **I suspect - given that Drive 2 has fallen behind (as it should be second) and Drive 3 has taken over - A bad drive :-( ** All 3 of have started running through their post read of cycle 1 of 3 at the moment (1%) and started running at about ~200MB/s. Post read figures: UPDATE 1: All 3 chugging along. Drive 1 at 50% and the other 2 not far behind on the post read of cycle 1 of 3 (Haven't experienced any more lag on disk2) and all running still at ~200MB/s (~44 Hours so far - LOL!) UPDATE 2: All 3 still chugging along. Drive 1 at 67% and the other 2 not far behind (10% or so) on the post read of cycle 1 of 3 and all running still at ~200MB/s UPDATE 3: All 3 finished at 100%. All were running at the end still at ~200MB/s. All three completed their post read with a FINAL speed at 100% of ~200 MB/s taking ~16 Hours. Total Time for cycle 1 was is ~52 Hours. Clearly whatever Brians version of the pre clear script does it makes the post read just as fast as the writes. Still ~52 hours for a pre clear though. Doing 3 cycles is painful - another 2 to go! LOL! Note: Cycle 2 has started. Ill only post anything if the figures look like they are going to differ significantly.
  22. UPDATE: Currently ALL disks are in cycle 1 of 3 preclear cycles (Currently in Pre Read). Disk 1 (Top Bay) is reporting - 37 C - Preclear Running Time: 14hrs 21 mins Disk 2 (Second Bay) is reporting - 40 C - Preclear Running Time: 13 hrs 12 mins Disk 3 (Third Bay) is reporting 34 C - Preclear Running Time: 13 hrs 7 mins It was a relativley cool night. In fact I went to bed a bit cold. When I went to bed Disk 1 was at 39 C, Disk 2 was at 41 C and Disk 3 was at 36 C I am quite surprised to see the temps are lower this morning. Given it is warmer and the sun is on the box too this morning - it was dark last night. A little concerned about drive 2 given what I saw before bed. I don't like to see my drives go over 40 C. Even on a preclear. But seems ok now.
  23. Having my first test of the airflow in this case. Running in the config as per my little diagram in previous post 2 side fans intake and rear one extracting! Fan speeds are stock based on default config - IPMI reports 1000 RPM. Whats in the box: ASRock C2550D4I Mini ITX Motherboard Kingston 4GB (1x4GB), PC-12800 (1600MHz) ECC Unbuffered DDR3L, ValueRAM, CL11, 1.35V, Single Stick Silverstone ST45SF-G 450W SFX Form Factor Power Supply - ST45SF-G 3 x Seagate 8TB Archive HDD, SATA III, 5900RPM, 128MB (in top 3 bays). There is nothing but trays in the remaining bays. Currently ALL disks are in cycle 1 of 3 preclear cycles (Currently in Pre Read). Disk 1 (Top Bay) is reporting - 37 C - Preclear Running Time: 1hr 40 Disk 2 (Second Bay) is reporting - 37 C - Preclear Running Time: 28 mins Disk 3 (Third Bay) is reporting 32 C - Preclear Running Time: 23 mins Currently the case has all vents and filters on and as the manufacturer intended. Lets see what happens!
