I am not 100% sure of that but with 3 SSDs as cache (since I have some folder duplicated x3) when I write to the pool into a folder without duplication then this is always the same SSD that is used. If I am correct then it would be better if write could be randomly done on one of the 3 SSD and not always the same one.

SSD Crucial BX100 250GB : wrong reported SMART temperature
propergol replied to propergol's topic in Compatibility
Ok I did test with BX100 on M1115 and it still shows 0°C. -
Thanks. Yes, after 10 years with watercooling cases (some were dual Xeon), I am now only doing air cooled stuff and even if its more challenging regarding temperatures, its way cheaper... A good controled air flow with positive air pressure can cool a lot of setup, with near to zero maintenance. Now that I use DrivePool, I would be able to keep the same case and if I need more data room, only change 4TB drives as price drop with 8TB, one by one... 72TB in a small mid tower with all HD under 35°C

SSD Crucial BX100 250GB : wrong reported SMART temperature
propergol replied to propergol's topic in Compatibility
hmmm... I am thinking ... I could try to plug the SSD on the M1115 rather than on Intel mobo port. But since this is my system's SSD I m not sure it would boot. Will try and report. -
SSD Crucial BX100 250GB : wrong reported SMART temperature
propergol replied to propergol's topic in Compatibility
The screenshot was made with version v 2.5.2.3103 BETA under Windows Server 2012 R2. I have just dicided to simplify my setup and give a test to Windows 10 as my server machine rather than running Server R2. Under Windows 10 with the same Scanner version I face the same issue : 0°C reported -
Sorry, I have "only" 4 SSDs I was just curious if dual link would increase single SSD read/write but it doesn't.
-
Small update : I did replace the original heatsink with a bigger and 100% copper one. I did fixed it with Arctic Sylver Thermal Adhesive, so it's permanent but much more efficient than thermal paste in this case. Then I did bended the heatsink pins one by one. The result is an impressive 20°C temp drop from 45-50°C to 27-30°C. I plan to do the same for the top M1115.

I did some tests with SSD and it doesnt help with "slow" queue read/write. I did have nearly the same results with one or 2 links. SSDs plugged into Intel's SATA 3 ports always give better results than SSD plugged onto M1115 or M1015 or to the expander : SSD on expander : On Intel's motherboard port :

SSD Crucial BX100 250GB : wrong reported SMART temperature
propergol posted a topic in Compatibility
I just swapped my system SSD from a Sandisk Extreme II to a Crucial BX100 and I did noticed that temp is read correctly in Scanner's SAMRT detail window (31°C) but is wrongly displayed in Scanner's main windows (0°C). BitFlock : RQKIA4F2 -
Some picts of my quick but functional SAS expander mounting A very efficient 350W TFX PSU : SAS mount : Mounted in the case. The setup isn't complete yet (but working). When completed it would have 1x 240GB SSD + 3x240Gb caching SSDs, 6x4TB + 3x5TB HDs : virtualy 39TB with SSD write caching x3. On this picture I was testing dual link between the M1115 and Intel SAS expander : Single link : I need some more work on cable management... But cooling is now perfectly tunned with SpeedFan that controls 5 case fans. HDs are between 29°C and 34°C and both SAS card's CPU below 45°C (thanks to a case fan puching air between both SAS cards).

Some could be interested : this guy has some Intel expander @ €99, free shiping to France from Irland so I think free shipping to Europe. I guess I should have wait a litle more. http://www.ebay.fr/itm/Intel-RES2SV240-24-port-6-Gb-s-SATA-SAS-RAID-Expander-Card-/111791366958?hash=item1a0748e32e

SMART values for SSD SanDisk Extreme II and PRO 240 Gb
propergol replied to propergol's topic in Compatibility
I hope you ll managed to fix it since all my SSD cache is based on 3x Sandisk Extreme Pro (also affected) as my system SSD, a Sandisk, Extreme II... A lot of "ghost" SMART values -
just a note this is without expander, since I haven't received it yet.

While I was experimenting with Scanner Burst test, I did noticed some strange behavior with 2 SSDs pluged into M1115 : reported burst speed is no more than 305MB/s and 296MB/s So I jumped on my benchmark directory and made some RW speed test on both SSDs : Results are much higher than Scanner Burst test. Both SSDs score virtualy the same : On a third SSD, that is system SSD and plugged into Intel mobo port, the burst speed reported by Scanner is higher : 500MB/s SSDs on M1115 are reported as SATA rev 3.1, SSD on Intel is reported as SATA rev 3.0 Burst test on HD RED 4To plugged onto M1115 = 466MB/s
-
Thanks. Don't waste time checking : I will receive the expander in the next days and so I will test it. You are probably right however, cabling from the expander to HDs and SSDs could do a nicer job in my small case. I will check what is the best option after receiving the expander.

Hi, I was wondering if some of you have dual link working between M1015 and Intel expander RES2SV240? It looks like Ethernet link aggregation but for SAS. RES2SV240 supports it but I don't know for the M1015 or M1115.
-
that is the way I did the first log
-
logs uploaded but I don't know if there is any info in the logs since the event 153 is recorded at shutdown, not when booting.
-
I will check again, but from what I can remember the disk was DrivePool disk, not a physical one EDIT : checked again and yes it is DrivePool disk. The error started after I did made a lot of firmware/bios/driver change for my IBM M1115, a lot of reboot, and now the error won't go away and appear each time the server is shut down or restarted. But no other issues so far.
-
For my familly usage and my brain health I would stick with ONE box : all of my technicals problems in the very same black box Regarding the auction, after some discuss with the seller I did bought the cables and of course the expander (but not the riser card) for....more than I should have paid... : $133 shipped to France. Since I can see it on Newegg.com @ $273, Amazon.com $265 without cables, it is not a bad deal, even if for a used part I found that still expensive.
-
Nice compact build. I am also trying to keep a small box, I would post some pictures later. One question : what kind of disk events were logs? Because on my build I get 1 disk event 153 each time I reboot. I wonder if it is hardware relate or maybe Windows side or DriverPool side.
-
Yep. Sounds right. I will offer at $90. Since I have a very cramped build : 9 HDs + 4 SSDs inside a litle mid tower, the expander powered with a Molex would offer better cable management than an other M1115.
-
Thanks. I have found what is the small card : it is a "riser" card and it seems it needs to be plug onto specific server ports. Also regarding the SAS expander : yes I do know that I need a contoller that is the reason why I did wrote that I already have a m1115. I did have a closer look to the expander pictures and if you look at the Molex, it looks like the heatsink has beegining burning it ... I will wait for something less "used"...

SMART values for SSD SanDisk Extreme II and PRO 240 Gb

and mine : Both SSD (Sandisk Extreme II and Sandisk Extreme Pro) have same ID : RQKIA4F2 -
I am still wondering if I should buy an other IBM M1115 or buy an Intel SAS expander... Expanders are not very cheap ... I manage to find one, not new RES2SV240, but it comes with an additional card and I don't know what it is. Here is the auction : http://www.ebay.fr/itm/Intel-RES2SV240NC-RES2SV240-24-port-6Gbs-SATA-SAS-RAID-Expander-Card-/161823139680?hash=item25ad692760 $200 for both cards and cables, do you think it worth it? What is the second litle card exactly? Thanks EDIT : I need a new SAS card or expander because I plan to use SSD for caching, at least 3, and I miss some SATA 3 ports.
