- Опубликовано: 11 сен 2024
- I want to run Hardware Raid on the 70 large drives in my HP D6000 storage DAS. And I want the M5210 raid controller in the awesome Lenovo x3650 M5 to be in charge.
We do this in this video with the Lenovo 00LF095 36port 12Gbps SAS Expander SAS/SATA Card. It is really an Adaptec AEC-82885T.

For 3$ a month, you get an extra weekly "What's UP" update video. Just for my Patrons. The Support I resave on patreon is all used on stuff to make interesting videos on RUclips.
My PlayHouse is a channel where i will show, what i am working on. I have this house, it is 168 Square Meters / 1808.3ft² and it is full, of half-finished projects.
I love working with heating, insulation, Servers, computers, Datacenter, green power, alternative energy, solar, wind and more. It all costs, but I'm trying to get the most out of my money, and my time.
Great video ... not just talking but showing the entire process in a first person perspective. Thank you for the info.
Hi Panagis Voutsinas
Thank You very much! glad you liked the video :-)
Thank you for watching! :-)
13:59 I've got 82885T and actually read manuals 😉 CN8, CN0, CN4 (port G,H,I) of 82885T does not support direct attach to disk: those ports are meant to connect to raid controller or upstream/downstream SAS expander. Therefore this card has total 36 ports and can connect up to 24 drives directly, as manual says. Also there is an updated firmware there.

Hi. Just ordered this on eBay, and anxiously awaiting its arrival, so I'm here to soak in as much info as possible.
I just saw your post, and I had to check the datasheet for the ports-order, and I actually didn't read this before, but it says:
"Maximum number of disk drives | up to 20 direct-attached" from the manual on page 15 of "Adaptec SAS Expander AEC-82885T"
A bit further down it says this:
Wide-Port to Controller, Wide-Port to Expander, Direct-Attached to disk
A, Yes, Yes, Yes - SAS ports 0-3
B, Yes, Yes, Yes - SAS ports 4-7
C, Yes, Yes, Yes - SAS ports 8-11
D, Yes, Yes, Yes - SAS ports 12-15
E, Yes, Yes, Yes - SAS ports 16-19
F, Yes, Yes, No
G, Yes, Yes, No
H, Yes, Yes, No
I, Yes, Yes, No
Where A to I are the ports CN0 to CN8
So, there's 4 less drives than you claim.
@yamamoto65536 You also mentioned a firmware update, will this change the number of drives?
@@mikaeleriksson7311 I tested direct attach to port F with fanout cable and a SATA drive is recognized on "Enclosure 1, Slot 20".
82885T Installation and users guide adaptec_sas_expander_iug_6_2016.pdf (Revision 1 May 2016) page.15, it says Maximum disk drives, internal : up to 24-direct-attached. And on page 18 says Connector F is Yes - SAS ports 20-23.
It seems new firmware 10.84.00 Build 053 provides Windows Server 2016 support and removed 32-bit Windows support.
I saw your video while searching for information about the card you have installed. Thank you for sharing. (In a small system, there was a system with MS-DOS installed on a 16MB flash hdd disk. 16MB flash hdd onboard on the motherboard and it was made in 1996 or something. In order to access the system and open MS-DOS, a floppy drive and operating system had to be installed. That's why the device came to me. So from that time to today.)
Hi timecomments

Thank you, I have been considering Adaptec SmartRaid 3258p with two 82885T for a DAS, and your video helps a lot, especially the cabling part of 19:00 :)
I really lost faith in Adaptec after the 7 series... and I've been using Adaptec cards since my ISA SCSI card... moved over to LSI, lets see if they let me down
@@flecom5309 thanks for your comment, I started to use Adaptec since AHA1542 and remembered their glorious 2940 iterations :) I like their current products because it is full featured out of the box and no software key nonsense. Also liked the HDD spindown feature for power saving that existed until 7 series or 8 series, but it is not there in SmartRaid 3100.
Hi yamamoto65536
Thank You very much! glad you liked the video :-)
Thank you for watching! :-)
Well this is an LSI raid controller with a Adaptec SAS Expander :-)
@@MyPlayHouse ya I'm sure the expanders are fine
@19:53 Alternative to percussive maintenance. I like it.
Hi Warrigt
Thank You very much! glad you liked the video :-)
Thank you for watching! :-)
nice you got that SAS expander working :)
Yes,,, Got pretty far in just one video :-)
73.5" hard drives? Those are huge!
indeed,,, :-)
I was advising you that one cable was needed from the controller to the expander but I guess you didn't hear me. lol
Speak UP man :-)
You should probably copy using software like teracopy for large files, it can use multiple cores and it might be faster
I think the HDD speed is the limit..
@@MyPlayHouse Actually I was using teracopy in xp era. When it was mentioned, I tried it immediately. I immediately used Teracopy to copy 650mb files to 4gb ramdriver. Yes normal explorer single core Teracopy hangs on all cores. Teracopy's caching provides a smoother copying experience. It's definitely fast. (Xeon e5 2666 v3 48gb Ram, 500gb ssd -> 4gb Ramdriver)
Hi there, but this way you're using 1 channel of the 12 gbps controller x4, to connect a bunch of disks...😮 and also take in consideration that the expansion matrix of the x3650 m5 includes already an expander 😅
Yes,, this is not the best way to get optimal performances,, but it is not that bad,, and for HDD it is okay.
@@MyPlayHouse Yes for SATA HDD in the lab, anyway I'm not sure (need to read tech doc) if this card supports natively (without expanders) until 8 lanes, up to 12Gb, and so each of the mini SAS channels are supporting 4 x 12Gb (48 Gb) or that is not the best way to measure it :))) ..... best regards and keep making these videos !
Ok it's clear, 12 GBps = 8 lanes at 1,5 GBps, so 2 connectors handling 6 GBps e.o.
@@josem9315one port is 4x12g sas or not ? So max truhput is more like 48gbps or not ?
+1 for truenas core/scale
Hi Niklas P.
Thank You very much! glad you liked the video :-)
Thank you for watching! :-)
Could the MOLEX be there for using the card as a passthrough. If you wanted to convert a case to be a DAS/JBOD?
Yes,, from how I understand it..
Did you need 2 wired connections from the controller to the SAS expander? For redundancy or increased throughout?
I believe it works with just 1
It'll work with only one of them, but by using the two you're increasing wideband
can you tell me what the power consumption of the giant jbod is?
8-10W per drive plus a bit... I have not measured it.
Can i use More then 1 uplink ? I need to connect 20?
Like lsi 9300 i8 with 2 cables
I do believe so,, but I have not tested.
Also Morten, couldn't you span the drives in raid controller? Like put all 4 virtual drives in raid 0?
I do not believe so...
@MyPlayHouse You put the Raid5 arrays on a single virtual drive, right?
Is all this huge system for CHIA mining? How much are you making with all this? Is it profitable taken into consideration the cost of all this equipment and electricity used? This is huge!
Raid 5 only with all these disks? more than 1 drive failing and you lose everything...
I am not doing Chia,, it does not make back the power prices at the moment.
What server is that 35 drive drawer server
It’s a storage DAS D6000 from HPE.
No raid6 as disks are large or/and a lot of them ? (especially with some disks maybe reporting problems)
@@Sommyie of raid6 its not zfs, parity and pre clear is a background task when creating raid on these hardware or software controlers and allows dual dual problems or failure (usually recommended on large amou of disks or/and large disks) unless you don't mind falling back to backup and restoring all that data
Raid6 is an addon to the raid controller,, I do not have that one.
@@MyPlayHouse shame that they did that with older raid cards, having to pay to enable raid6 is silly (such large amounts of disks really needs it)
I plan to use the old molex with this card in my system but where is the card supposed to go if I do this as it can’t be plugged into the pci port , please help on this one ☝️
No you can't have it plugged in a PCI and molex at the same time,, but I am sure you can strip it to the side or something.
@@MyPlayHouse thank you very much for replying, the message helps as I knew I couldn’t use both at the same time but wasn’t sure what to do with it 👍 ty
I’m looking at this to use with a 9560-16i with my UnRaid build that is used for Gaming VM as well as Plex, and dockers and shares to be used with my HomeLab zip setup.
It is a cool card!!
Hi Where do you buy your ssd from ?
all over the places,,,
Hello, just a heads up! That coupon code is not valid anymore. :)
Thank You Very much,,, Bargain Hardware has renewed it now :-)
How would if fit with an LSI 9206-16e ??
I do not know,, I do not have one of those...
YEA IT SUCKS TO LOSE PLOTS .
