MaxNL Posted April 23, 2012 Author Share Posted April 23, 2012 Attached to this post there is the syslog of my server. I would really appreciate if someone can have a look at it and tell me if there is something I should take care of. Thank you in advance. syslog-20120423-233555.zip Link to comment
MaxNL Posted April 25, 2012 Author Share Posted April 25, 2012 A quick question: what SATA 2 SSD should I use just for cache in unRaid? Link to comment
BetaQuasi Posted April 26, 2012 Share Posted April 26, 2012 Anything you like - there are no Marvell-based SATA 3 drives, so no advantages around advanced garbage collection. However since the nature of the cache drive is that it would never be filled anyway (constantly emptied) any drive will do the trick. Just pick a size that will cover the most you'd possibly transfer in a 24 hour period if you want all your transfers to be done at maximum speed. Link to comment
Johnm Posted April 26, 2012 Share Posted April 26, 2012 Actually.... If you are getting a SATAII SSD for unraid.. see if you can find a Kingston SSDNow+ (it has to be a plus version)... they have an auto advanced garbage collection for systems that dont support trim.. We use these in our Macbooks at work just for this reason. I kept telling myself I wanted one for my cache drive, but they sort of vanished overnight at the same time as the flooding in Thailand. see here for some details http://www.scribd.com/doc/58523351/Kingston-SSD-Garbage-Collection Keep in mind, this is all from the SATA2 (SATAII) generation of SSD's. I do not believe the SATAIII (Sandforce chipset) Versions have this feature (I could be wrong). For newer SATAIII SSD's, I would get the Corsair Performance Pro SSD'd Link to comment
MaxNL Posted April 26, 2012 Author Share Posted April 26, 2012 Thanks. Sorry to bother but I have another question. I installed unmenu and for all drives (5 Hitachi 4TB) it does show the HPA? message. I did some check: 1) before I assigned the drives to unRAID all of them reported in syslog to be 3.907.018.584 2) After I assigned them to unRaid (formatted and parity done) from the syslog I can see in the same size (3.907.018.584) in the drive inventory section and the size 3.907.018.532 in the mdcmd/md section 3) In the standard web interface I can see all the driver reported as 3.907.018.532 4) in the unmenu web interface the size reported is also 3.907.018.532 5) if I run hdparm -N i get "HPA setting seems invalid (buggy kernel device driver?)" message 6) in the syslog I also get another message by unmenu "WARNING: GPT (GUID Partition Table) detected on '/dev/sdb'! The util fdisk doesn't support GPT. Use GNU Parted. (Minor Issues)" Do I have to worry about that, could it be a false warning by unmenu? Thanks in advance for the help.

Both the following SSD drive have the "garbage collection" function SATA2 - Drive SSDNow V+100 - 64 GB – 96 GB – 128 GB – 256 GB – 512 GB (Looks like isn't available anymore) SATA2 - Drive SSDNow V+180 - 64 GB – 96 GB – 128 GB – 256 GB Link to comment
Johnm Posted April 26, 2012 Share Posted April 26, 2012 Sorry, yes the SSDNow V+ They sort of just vanished overnight. Link to comment
MaxNL Posted May 2, 2012 Author Share Posted May 2, 2012 Here are some statistics of my server during preclear (2 x 300GB) and parity check (5 x 4TB). So... it seems I solved the temperature problem (changed the three 120mm fans). Now I'm working on few details inside the case before starting to really use the server... Link to comment
graywolf Posted May 2, 2012 Share Posted May 2, 2012 Nice graphs. What did you use to produce them? Link to comment
MaxNL Posted May 2, 2012 Author Share Posted May 2, 2012 Excel.... Just made few vba procedures that use the unraid web interface (unmenu) to gather some data every minutes... after that is just excel standard Link to comment
graywolf Posted May 2, 2012 Share Posted May 2, 2012 would you mind sharing/posting your vba procedures? Link to comment
MaxNL Posted May 3, 2012 Author Share Posted May 3, 2012 I decided to go to the Virtualization path... I shall start probably tonight, for sure I will follow the Jonhm post... Any advice is welcome... I plan to run just UnRaid, Windows7 (at least at the beginning). I will use only one drive (300GB) for datastore and a flash drive for Esxi installation. I think the small HD shouldn't be a problem as far as my configuration stay so simple. Link to comment
MaxNL Posted May 3, 2012 Author Share Posted May 3, 2012 would you mind sharing/posting your vba procedures? Not at all... but consider it is quite a mess (I'm not a programmer). I will post it as soon as I made a small guide (you need to create an adhoc view in unmenu with a specific list of column in a specific order) Link to comment
Talsit Posted May 3, 2012 Share Posted May 3, 2012 Max, I did virtualization too with ESXi 5.0. I installed it directly to a 320GB 2.5" drive attached to the motherboard. This drive is also my datastor, I'm running: 1. Windows 7 (because I had a spare copy) 2. Windows Server 2008 (something I'm studying) 3. Windows XP (originally using this to do remote management) 4. Ubuntu 5. LAMP 6. unRaid 7. VMware management VM I don't have any issues, but beyond antivirus and OpenOffice I don't have much installed on any of these VMs. 1, 2 and 6 have thin provisioned 80GB virtual drives. 3 and 4 have 40GB thin provisioned drives 5 and 7 have 10GB thin provisioned drives 6 has 2GB thick provisioned The only time I have a slow down is when I start all 7 at the same time. Once they are all running and their services are started I don't have any issues. There might be a way to attach a datastor to unRaid (NFS or something along those lines) but I haven't investigated that line of thought to a solution yet. If I did that I would just have unRaid start on the attached drive and move the rest off to unRaid. Link to comment
BetaQuasi Posted May 3, 2012 Share Posted May 3, 2012 You can define a NFS-based datastore, but I wouldn't recommend it. If you *did* do that, I'd specifically do it to a disk share and NOT a user share. I wouldn't recommend it because the parity calculations of a constantly changing vmdk file would likely cause performance to be rubbish. Also there's the fact that there appears to be issues with NFS at the moment. Just use a dedicated datastore drive Link to comment

Just use a dedicated datastore drive Just to clarify, NFS for datastore is excellent, but unRAID is not a top performing NFS platform with full random read/write IO. Link to comment
BetaQuasi Posted May 4, 2012 Share Posted May 4, 2012 Well of course NFS generally works, but he was asking in the context of unRAID Link to comment

HiSoC8Y Posted May 18, 2012 Share Posted May 18, 2012 So at the end I decided to build my new server. (I should blame this forum the most for make me do it ) I decided to go for a "beast" kind of server (inspired by Raj's Prototype Designs). The building and the setting has been fun and rewarding, but let's start with the lists: Components - List: Item - DescriptionLink#Note Case - Norco RPC-4224>>124 HDD in the frontal bays. The plan is to add the cache drive not using them Motherboard - ASUS P6T7 WS Supercomputer>> 17 PCIe 2.0 at 8X, plenty of room for expansion CPU - Intel Xeon DP E5620 >> 1Should be more than enough to cover all the possible Add-On and media decoding RAM - Kingstone ValueRAM - KVR1333D3N9K3/12G >> 2I grew up in the '80 were we used to say: there is no such thing as too much RAM - 24GB Total PSU - Enermax Platimax 1500 >> 1Plenty of power, no redundancy, soon I will have a UPS SATA Controller - Supermicro AOC-SAS2LP-MV8 >> 3I won't need anything more for long time, 24 HDD ready Fanplate - Norco 120mm fan wall bracket>>1Keeping the noise down Fans - CPU Cooler - Noctua NH-C12P SE14>>1Keeping the noise down Fans - Fanplate - Noctua NF-S12B ULN>>3Keeping the noise down Fans - Case - Noctua NF-R8>>2Keeping the noise down Video Card - ASUS EN210 >>1No Video on the motherboard just a cheap card without cooling fan Hard Disks - Data - Hitachi Deskstar 7k4000 4TB>>522x4=88TB, and 2 parity disk, waiting for that upgrade to UnRaid Hard Disks - Cache - Western Digital Velociraptor 2,5" SATA2>>2For cache, plugged in raid0 on motherboard SAS connector Case Accessories - Air Slot RZ065>>7Just nicer than the standard one Case Accessories - Scythe Bay Rafter 2,5 to 3,5 HDD Mounting>>1To mount the 2 WD Cache HDD without using the front bays Case Accessories - NZXT Premium Cable 3pin fan Y cable>>14 fan plug on the motherboard vs 5 needed, the splitter solve that Case Accessories - Lian Li Power Supply Rubber PT-PP03B>>1noise control Case Accessories - Inline SATA To 2xMolex splitter>>1Keep everything properly connected reducing the cable cluttering OS - unRAID Server Release 5.0-beta14>>1PRO Licence Components - Pictures: The Norco Case ASUS Motherboard Kingston RAM http://www.norcotek.com/product_images/rpc-4224b.jpg[/img] http://www.forumpcs.com.br/galeria/albums/userpics/20281/000000088286.jpg[/img] http://www.nix.ru/autocatalog/memory_modules_kingston/113461_3159_draft.jpg[/img] Enermax PSU SATA Controller Fanplate http://www.enermax.com/files/ProductPicture_eng/PP_Pic/1285.jpg[/img] http://www.supermicro.com/a_images/products/Accessories/AOC-SASLP-MV8.gif[/img] http://cybershop.ri-vier.nl/images/Accessoires/120mm-fwp.jpg[/img] Noctua CPU Cooler Noctua 120mm Fan Noctua 80mm Fan http://www.noctua.at/images/products/fullsize/noctua_nh_c12p_se14_2.jpg[/img] http://www.noctua.at/images/products/fullsize/nf-s12b_1.jpg[/img] http://www.noctua.at/images/products/fullsize/noctua_nf_r8_1.jpg[/img] ASUS Video Card Hard Disks - Data Hard Disks - Cache http://www.mobilx.hu/images/detailed/en210_silent_di_512md3_v2(lp)_00.jpg[/img] http://www.hitachigst.com/components/com_virtuemart/shop_image/product/Deskstar_7K4000_4f036682bcca3.jpg[/img] http://www.boendiy.com/image/pro_img/Western-Digital-WD3000BLFS.jpg[/img] Slot Covers 2,5" HDD Mounting Fan Cable Splitter http://www.revoltec.net/revoltec.net/data/media/_pms/rz065/scaled/rz065_m.jpg[/img] http://www.scythe-usa.com/product/acc/058/images/bayrafter2.5-main2_400.jpg[/img] http://a248.e.akamai.net/origin-cdn.volusion.com/2thoc.9vr6n/v/vspfiles/photos/PC-CB%203P%20Y-2.jpg[/img] Power Supply Rubber SATA To Molex Adapter unRAID http://lian-li.com/v2/tw/product/upload/image/pt-pp03b/pt-pp03b-01.jpg[/img] http://www.overclockers-store.com/images/large/INLINEsataTO2molex_6fRnFA6x071x_large.jpg[/img] Hello Max, I was wondering, isn't this a overkill? Got couple of questions: - Why using a xeon, why not i5 or i7? i noticed that the motherboard's SATA support only 3 Gbps. Why did you go with this one, while you spend sooo much on this build? Why didn't you pick a board that supports 6 Gbps? i'm a newbie with unRAID. Link to comment
S80_UK Posted May 18, 2012 Share Posted May 18, 2012 I would go with more powerful fans for the drives. The Noctua NF-S12B ULN is very low power and will not move much air. You need to think about the static pressure that the fan can deliver as well as volume. The NF-S12B FLX or NF-P12 are both still very quiet but will be much more effective at moving air past the drives due to their blade design. You can still slow them down if needed (like other Noctua fans they come with speed reducers) and they will still be better than the fan you have chosen. ( Refer to the Noctua website for the technical details if needed - www.noctua.at ) Link to comment
