I can comment on this. I recently switched from 1 x MV8 to 2 x M1015 First of all, HDDs can't even reach max speed of SATA II (3GB/s), so SATA III or SATA II, that doesn't affect much. and there is almost no performance gain in terms of copying stuff to or from unraid when using M1015 or MV8. HOWEVER, you see the improvement when it comes to Parity Check or Data Rebuild. M1015 uses PCIe x8, which is able to do 1.6GB/s single direction. MV8 uses x4, which is able to do only 800 MB/s so let's say you have 8 drives plugged in to one of these cards. and let's say your hdd's are able to read 110 MB/s max (this is what i saw during preclear for most drives during pre-read). If you were to use MV8, your speed will be limited to 800 MB/s or less. it can never reaches that high. that's just theoretical speed. With simple feature stats plug in, you can actually see the transfer speed of all drive during data build / parity check. I was getting about 500 MB/s. again, this is from SIMIPLEFEATURE STATS. On the index page, i was seeing about 80 MB/s for parity check. When I switched over to M1015, I was getting about 700 - 800 MB/s total. and about 100 - 120 MB/s during parity check. (i also removed green drives from my array which increased my speed as well). SO with MV8, parity check took 10 - 11 hours, with M1015, took about 7 - 8 hours or less. it is a big improvement in my opinion. So, to sum it up. In regular usage, there is no difference because you're accessing 1 or 2 drive at time, so it doesn't get limited by PCIe speed. However, when you're doing the parity check or data rebuild that uses all 8 drives at the same time, you see improvment.

Yes it's possible since your array data is actually stored in the flash drive and you use that to boot the VM. That link should be a good guide on how to do this. However, without being able to do hw passthroough, like i said before you have to do RDM for all HDD's you have, there is no way around it. I am not a big fan of RDM personally, so I wouldn't go with esxi if my hardware doesnt support hw passthrough.

You don't have to passthrough the NIC. you can just add virtual NIC that's provided by esxi. It's normal to say inactive under DirectPath I/O if you have a virtual NIC. i dont know if precision 690 supports hw passthrough. If you go to BIOS, do you have VT-d or some kind of vitualization setting? if it doesnt support, you're going to have to use RDM for all your hdd which is not too convenient.

You just add it as a usb device in your VM. Go to the setting screen on your VM, Click "Add...". Add USB Controller, then you add USB Device See this post: http://lime-technology.com/forum/index.php?topic=14695.msg138465#msg138465 Scroll down to "VM#3 unRAID VMDirectPath Hardware Passthough"

i'm pretty sure there is no multiple NIC support in unraid. so even if you have multiple NIC's plugged in, it will only see one and use that one.

I believe the reason is because M1015 is a software raid card and unraid doesn't have the correct driver for it when it's raided. and i can't find where i read it, but i read somewhere that if it's in default mode, HDD won't be detected by OS's if HDD's are not in raid. so if you dont make them in raid, hdd's wont be recognized by unraid. if you make them in raid, the raid wont be recognized by unraid. so IT firmware is necessary. but, IR in other hand may be different. in the article that you posted up about M1015, it talks about M1015 being able to be in three different mode: LSI9211-IT, LSI9211-IR, LSI9240 (Default) (http://www.servethehome.com/ibm-serveraid-m1015-part-4/) sounds like IR mode is IT mode + raid capability. but again, it comes down to unraid's raid driver. maybe someone else can answer if RAID using IR mode is supported by unraid

actually, power consumption is lower than green drives See these pdf docs for detail: http://www.wdc.com/wdproducts/library/SpecSheet/ENG/2879-771438.pdf http://www.wdc.com/wdproducts/library/SpecSheet/ENG/2879-771442.pdf but here is the power management part of it: WD30EZRX (Green 3TB) Read/Write: 6W Idle: 5.5W Standby/Sleep 0.8W WD30EFRX (Red 3TB) Read/Write: 4.4W Idle: 4.1W Standby/Sleep 0.6W I am slowly changing all my drives to Red drives..

Nope, it's actually very low http://www.tomshardware.com/reviews/red-wd20efrx-wd30efrx-nas,3248-8.html and performance per watt is one of the best. green drives are low too. could be lower than red, but the performance is not worth it. i recently moved my green drives out of the array, and my parity check and build performance went up pretty high

I never ran 4.7 before. I jumped straight to 5.0 beta.. but i had the same problem before on 5.0 where unraid would lose the connection. it kept losing connection when i try to copy >10GB files. so when it lost the connection, i went on the machine console and typed these to renew the ip address ifconfig eth0 down ifconfig eth0 up It crapped out on me and gave me some weird error i remember. it was because of RAM. for some reason, it gave me out of memory error in the syslog and it was shutting down the ethernet card. and when i try to renew the ip address, it's not able to cause it completely shut down ethernet card. so this is why we would need the syslog after losing the connection. as you expand your storage, it may require more ram. (i am not too sure on that though).. I'm guessing you still have 2GB as you mentioned earlier? anyway, i fixed my issue using this though: http://lime-technology.com/forum/index.php?topic=3999.msg36211#msg36211 I used 65536 instead of 8192 like this: echo 65536 > /proc/sys/vm/min_free_kbytes if this fixes the problem, better to put it in go file

Are you getting the syslog after you lose the connection? or are you getting the syslog in the middle of the big transfer? We would need the one after you lose the connection, not in the middle of the transfer. and i dont know if i missed it, but did you run memtest overnight to see your memory is okay?

Yea PART 4 is a good article about flashing the firmware. It has the link to the zip file that includes the latest firmware (P15 i think) and efi version of sas2flash. It doesn't mention anything about uefi shell in that specific article though, but if you can go to uefi shell, the instruction's the same.

okay. here's another info. recently i bought M1015 to replace my MV8. However, in earlier posts, people mention that they weren't able to flash it to IT firmware using 970 extreme4 Well, I was able to flash M1015 without any problem using built in EFI shell in 970 extremem4! no need to try to flash it from a different mobo this is what i did pretty much: http://lime-technology.com/forum/index.php?topic=20761.msg186485#msg186485

oh lala! this is awesome! hopefully Zeron sees this post soon.

yea, like Joe said. It is completely insecure. Never meant to be accessed directly from outside. I believe it was designed to be internal use only. I have set up a VPN server using my router, and that's the only way I connect to my unraid from outside. Even if it was 'secured' though, you should never make your file servers available directly from outside world in my opinion.

All gone now. That was fast. For those still looking for M1015, here are sellers that's selling it for about $90-$95 ish. I've been watching them over the week and they have been lowering their price slowly.. So it is possible that they may lower it more so may want to watch They don't include the full bracket though, which you have to buy separately. $85 + $5 Shipping (Could try make offer): http://www.ebay.com/itm/IBM-SASSATA-M1015-DP-PCIE-SAS92208i-46M0861-46M0831-46C8933-SHIPS-TODAY-/321093220404 $94: http://www.ebay.com/itm/IBM-SERVERAID-M1015-ADAPTER-PCIE-20-X8-SAS-SATA-CONTROLLER-46M0861LOW-P-/310640105140 $95: http://www.ebay.com/itm/IBM-ServeRAID-M1015LSI-SAS92208i-PCIE-SASSATA-46C8933-Half-Height-Low-Pro-/171015898712 These are the price for them at the time of writing this post. Good luck!

lol let's not be so greedy now. i'm just sad that I could have waited 2 days to save $25 I literally orderd it two days ago (Sunday) I thought no one would sell it under $100 anymore. bahhh was i wrong. at least i got one for $80.

I've been looking into getting this card for awhile..but it's been over $100 over at ebay without the bracket But finally, someone just posted it up for $80 with the full bracket.. I bought one last week for like $105 but i ordered another one lol http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=200912082875 At the time of writing this post, there are 3 left.

Why not G1610? http://www.newegg.com/Product/Product.aspx?Item=N82E16819116889 Same price ($49.99), better benchmark score from http://www.cpubenchmark.net/ (2366 vs 2618), ivy bridge, and lower power consumption (65W vs 55W)

A lot of unraid users use that card. They refer it as 'MV8'. I use it myself. It is also listed in the hardware compatibility list in wiki : http://lime-technology.com/wiki/index.php/Hardware_Compatibility#PCI_SATA_Controllers

I had G530 for the longest time until I got the esxi machine set up. G530 is enough for all plugin including plex Sent from my Galaxy Nexus using Tapatalk 2

Getting off the track here.. but i honestly dont think it's doing it wrong. maybe not using the main feature.. but not really doing it wrong. someone can use unRAID with 1 drive if they don't need data protection but need quick NAS solution. All they need would be unraid flash drive, and a pc. without any much setup, they've got themselves a simple NAS solution. They can expand their NAS by adding another. so unRAID with 2 drives there.. If they want to protect their data with the parity drive, then they can add the parity drive.. Not every data needs protection.

I've been looking into itx builds as well... but from my research C60M1-I is not good enough for plex and couchpotato. so it is a good thing that you didn't get C60M1-I for that purprose. As trurl pointed out, a lot of people are using i3-3220T for low power consumption (35W) and pretty powerful. However... I've been looking at G630T instead.. It is cheaper than i3-3220T.. same power consumption (35W). . If you don't care too much about the power consumption and low on budget, I'd go with Celeron G1610. It's 55W and it's about $50 over at newegg.. and it should be powerful enough for transcoding (plex) and sab + cp + sb set up.

I have AOC-SASLP-MV8.. but i heard they use same or similar chipset. Did you try the MV8 hack shown in this thread: http://lime-technology.com/forum/index.php?topic=14695.0
