there is a animated picture on this page that gives me an idea: http://finalcutprox.net/how-to-add-24tb-of-storage-to-a-mac-pro 2 5,25 bays with a x-swing with 2 normal height hdd's in there. In the top bay there will not fit another one with 2 drives

I can get them for 6 euro, so it is not a big investment. I now use 5 in 3 units from norco (attach sliders to hdd, slide in) like 12 Euro each, but they are not really locked in well. Cooling i would fix with 120 mm fans in front of it from top to bottum.

I was thinking of using on top of each other. 12 bay case, but if i can only place1 hdd per 5,25 bay, it is not of much use. If i could place 4 discs in 3 positions, i can hold 16' which is almost enough. Might order 2 sets to try out

Question on that double twin mounting. I assume it take more room than 1 5,25 bay height when 2 hdd are fitted. Can someone tell me how high this is (in mm preferably) Thansk..

Want to bring this question up. If i do a ps, i see no mover process that i can kill. My system decided today to do moving at 500 KByte/sec, so this takes days. I had issues enough with the discs it moves to, to reboot the server. Pressing the stop array did not work. Any oppinions ? edit: returning after dinner and no webgui, no telnet, but console still works samba was stopped finally no more mounted discs. did umount for every disk, (umount /dev/md1 .. were not mounted anymore) did /root/mdcmd stop shutdown -h now does not get the server dwon: stopping system message bus unmounting remote filesystems /etc/rc.d/rc.apid: line 15: kill: (1385) INIT: no more processes left in this runlevel and than a flashing cursor, and no more action.

The sound level the Seasonics produce is very low indeed. Have them in 2 PC's (14 and 17 hdd's)

Yes, i have precleared a Toshiba 3T with the standaard preclear command. This was done in 25 hours (i3-2100t processor and 16 GB RAM on a sata-600 interface )

Other sata data cable, other power cable, same drive, same errors at 65% Other drive of same type continues with pre-clear. So drive issue i assum, will put it aside

Thx, i will do that once i get back home today after work. The SDI drive was continuing just fine it seems, so i guess i will have the 3 preclear files of that one. The drives are on one power cable with 4 sata connectors (2 used) - original cable that came with the Power supply (monster realpower M1000) No splitters there. The Sata cable is a SFf-8087 splitted to 4 sata data connectors. The 2nd preclair on this SDH drive i did on a other sata data connector on which i pre-cleared a disk fine. Is there a reason to suspect the quality of these SFF-8087 breakout cables ? http://cybershop.ri-vier.nl/discrete-sff8087-to-4x-sata-mini-sas-forward-brkout-cable-l50-p-103.html edit: they look a lot like these: mono price for $9.63 (payed like 20 euro) I had massive issues on my Areca also, if these things could be caused by the cables i would be wise to buy other ones to test perhaps. edit: (8-8-2012) the 3rd go failed as well. According to seagate i still have warrantee on this disk, so i will go for a swap of the hdd. Will get a seagate back it seems, do not know if i am very happy with that..

I can imagine if this takes to long unraid times out.

I pulled the card from the system. I had several crashes/hanging system and always a drive on this card had the mvsas issues. Perhaps the combination of the marvel chip with the lsi sas expander chip behind is critical with timings or such. I do not care to find out, i will buy a 8 port card which has better reputation. If i need more drives than 6 + 8 i might look for another mainbord with more pci-e slots. This card is not advised for unraid as far as my experience till now. Hopefully people will stay away form this product.

Jowi, yes i thought of you. Well, 4 out of 6 drives were working. I think 4 on one split out cable was too much. Anyway, i will re run the 2 failed disks.

Johnm, I run with 4 MB of Ram on a ATOM based mainbord: Supermicro X7SPA-HF I posted the errors i received here: http://lime-technology.com/forum/index.php?topic=4068.msg191817#msg191817 I though of a issue with pre-clear, but there i think my memory was indeed the issue seen in the error in the above mentioned thread. So it was not wise to start with 6 discs i guess. On the bandwidth. It is a 16 port SAS non raid controller with PCI-E 4x From the Marvel Site: The first product in Marvell’s SAS controller portfolio is the Marvell 88SE6440 host controller, supporting four SAS/SATA ports. The 88SE6440 offers 4-lane PCI-Express connectivity to the host system for high throughput in bandwidth-hungry applications From their PDF: 88SE6440 PCIe x4 to 4 SAS/SATA 3Gb/s Ports RAID Controller From the sata wiki SATA revision 2.0 (SATA 3 Gbit/s)Second generation SATA interfaces running at 3.0 Gbit/s shipped in high volume by 2010, and were prevalent in all[citation needed] SATA disk drives and most PC and server chipsets. With a native transfer rate of 3.0 Gbit/s, and taking 8b/10b encoding into account, the maximum uncoded transfer rate is 2.4 Gbit/s (300 MB/s). So with this LSI SAS expander behind the Marvel chip there is never more than 4 times 300 Mbyte/sec This must be somehow shared between the 16 ports, i assume every 4 usable sata interfaces share one Marvel Sata interface as 4 x 4 = 16. Than each physical interface can use maximal 300/4 = 75 Mbyte/sec I saw 2 discs doing around 150 Mbyte/sec in the pre-clear, and 2 rather slow ones at the start which failed after like 1 hour and some minutes.

After some more checking on the web i think that it has a Marvell 88se6440 for the connection to the PCI-E 4x slot. It than outputs 4 SAS/SATA channels of 300 (?) Mbyte/sec into a LSI SASX28 which seems to be a port muliplier. http://www.marvell.com/products/storage/Serial_Attached_SCSI_SAS_Storage_Controller/release/742/ So i fear every SFF-8087 connector (behind the SASX28) which fans out into 4 SATA cables is in fact sharing 300 (?) Mbyte/sec from one of the Marvel 'channels' If this info is correct, i am not surprised it stopped working for half the discs as i had 4 times a hdd connected that does >150 MB/sec on the outer sectors. 2 were working, 2 not... (or better said: slow at start, stopped after 1 hour 40 minutes) Have to try out this: Not do connect 4 drives on one fan-out cable, but distribute across the 4 fan-out cables to utilise all the 4 channels. One question left: Will this work with parity calculation where every disk is read (i assume starting at the lowest sector for all disks at once and than work its way up)

The 2. 14% ones seem stuck, their run time counter does not increase anymore.

Was i simply out of memorey there ? I did run a pre-clear on 6 drives at once. An 320 GB succeeded, 3 x a 4 TB disk is still running, and 2 are stuck. After this error the syslog is filled with these: Jul 22 01:49:40 Tower kernel: sas: command 0xc0f20f00, task 0xd3496640, not at initiator: BLK_EH_RESET_TIMER Jul 22 01:49:40 Tower kernel: sas: command 0xdd93bc00, task 0xc75472c0, not at initiator: BLK_EH_RESET_TIMER Jul 22 01:50:11 Tower kernel: sas: command 0xc0f20f00, task 0xd3496640, not at initiator: BLK_EH_RESET_TIMER Jul 22 01:50:11 Tower kernel: sas: command 0xdd93bc00, task 0xc75472c0, not at initiator: BLK_EH_RESET_TIMER This last error is reported on this site with issues with 3 TB drives also: http://lime-technology.com/forum/index.php?topic=15810.0 This specific error perhaps comes up in google search frequently like this one: http://www.spinics.net/lists/linux-ide/msg42602.html Perhaps me starting 4 times a 4 TB hitachi 7K4000 was too much data for the Areca, or simply too much for the system, as on the mainboard an hitachi 320 Gb and a 4TB were also preclearing. I will wait for the 3 curently running ones (1 on mainboard and 2 on the areca) and reboot and retry the failed 2. (one on the areca and one on the mainbord than to compare)

In the meanwhile i received my components, and now all seems to work. I have precleared 1 TB via the mainbord, and now running 5 drive pre-clear (1 via mainbord, 2- 4 via the ARC-1300) Strange effect though: 1) 76% - 36 degrees 2) 14% - 40 degrees 3) 66% - 41 degrees 4) 65% - 40 degrees 5) 14% - 37 degrees So i seem to have 2 slow ones, and 2 faster ones. These drives are all connecte via an sff8087 to 4 sata cabel. Perhaps config issueon the areca ?

i looked up all the manufacturers specs for my hdd's: Hitachi 7K4000 2,0 Hitachi HDT721010SLA360 1,87 Samsung HD103UJ 2,4 Samsung HD145UI 2,0 seagate ST2000DL003 2,1 All values for Amperage at 12 volts during startup This would be around 47 amps at startup for the 12 Volt.

Is a seasonic Platinum powersupply advised nowdays ? http://www.seasonicusa.com/Platinum_Series.htm I will have 22 hdd's i think, most of them 7200 RPM. Is the 860 enough (71 AMP) or better the 1000 (83 AMP) The drives: 7200 RPM Hitachi 7K4000 (4TB) (5) Hitachi HDT721010SLA360 (1TB) (5) Samsung HD103UJ (2) green: Seagate ST2000DL003 (2TB) (3) Samsung HD145UI (1.5 TB) (5) Growth/replacement most likely hitachi 5K3000 / 7K4000 edit: only 22, no more sata ports edit 2: 'only' 11 Sata and 8 molex connectors.

Dhcp did not work, so i did put in a ip address manually. Is there a text based gui ? I should read more info first i guess. The description of the http based gui seemed clear, so i hoped to use that

I could not do much during my tests unfortunately. I have issues getting the LAN to work. I configured the eth0 with fixed ip, but it comes up in 10 mbps half duplex. I cannot ping the default gateway (i am sure on the ip adressing) How do i set the ethernet config to 1000 full fixed ? I assume if i get the ip connection working i can use a other device to browse to the web interface of it and have a more manageble interface (for me as a non linux user at least)

Hello all, i am new to this forum. I am thinking of setting up a unraid server. For sata ports i have a Areca ARC-1300ix-16 available. http://www.areca.com.tw/products/sasnoneraid3g.htm I did download a free version of unraid (unRAID Server 5.0-rc5 AiO) and created abootable usb flash disk (sandisk 8 GB) For test purpose i used my main PC which is a Asus P6T WS pro mainbord with i7 and 12 GB ram. X58 / ICH10R - 2 x Realtek® 8111C PCIe Dual Gigabit LAN controllers and only that areca controller with one 320 GB hitachi disk attached. It seems to start ok, end i end up on the linux command prompt. If i browse through the syslog i see the following entrys: Jul 6 18:37:24 Tower kernel: sas: Enter sas_scsi_recover_host Jul 6 18:37:24 Tower kernel: ata7: sas eh calling libata port error handler Jul 6 18:37:24 Tower kernel: sas: sas_ata_hard_reset: Found ATA device.

If this controller really works i intend to buy a supermicro ATOM mainbord http://www.supermicro.com/products/motherboard/ATOM/ICH9/X7SPA-HF-D525.cfm I have also orginal Cooler Master CM Stacker case, and a coolermaster 1000 watt power supply spare for this. I can than go for 3 times a 5in3 module and so go to 15 drives without to much cost in the hardware outside the new 3 TB Hdd´s Thanks for any help. syslog.txt
