Intel Xeon D-1500 Series Discussion

Yeah, already BIN and shipped Non-EU sellers is usally killing our deals as you'd need to add 25%+12.5% at customs (Sweden).

Ouch ! Makes the taxes we complain about seem not so bad ! 7% or 10% + shipping depending on which country I am thinking about shipping it to.

I have a Qnap TS 470 NAS was able to passthrough its onboard Sata controller to Vsphere 6 (its Intel cougar point 6 port Sata controller)... a lot of times onboard Sata did not work with pass through is becoz mobo maker share/bridge PCI address with other onboard/physical PCI slot. Sometimes its the PCI switch chip on the Raiser Card makes PCI passthrough failed. Keep in mind that raid cards and Sata controller are very picky cannot share address at all. But nic are lesser picky, and that's why sometimes we the same PCI slot passthrough nic without problem but raid card failed.

You can't pass through the SATA controller on SOC chips because they're integrated in the processor. You can, however, get an HBA and pass that through fine.

The Cougar Point is a separate controller that is integrated in C6xx chipsets to the motherboard, so it's a separate PCIe device.

Actually you can, I've done it on my Xeon D boards with the advice of another post in this thread. I'll see if I can dig it up.

EDIT: See this post.

Hello, does somebody know if there is a 19" 2U or 1U rack chassis that fit for the supermicro X10SDV-TLN4F (Xeon-D-1541, Mini-ITX) board. I read that IamSpartacus has been using the X10SDV-7TP4F (Xeon-D-1537, Flex-ITX) with the SC113MTQ-330CB chassis, but I would like a Xeon-D with min. 2Ghz base cpu frequency.

Oh, no kidding? That's good to know ...(!)

In the first link are three chassis that are optimized for that mainboard.
I think you can use all Supermicro chassis revision b or newer (eg 826Be16-R920LPB).

Yes but the two chasis listed (SC504-203B and SC505-203B) only accept max. 4x 2.5" disk or 2x 2.5" disk with PCI. The X10SDV-TLN4F MB accept 6x SATA ports... If I want to add a RAID PCI controller I could not do this with more than only 2 disk...

So for a 2U I could also use e.g. SC216BE1C-R920LPB chassis?

any chance, that the xeon d 1541 can be used with more than 128gb ram?

e.g. with
Samsung LRDIMM 64GB, DDR4-2400, CL19-17-17, reg ECC (M393A8K40B21-CTC)
Samsung LRDIMM 64GB, DDR4-2400, CL17-17-17, ECC (M386A8K40BM1-CRC)
Samsung DIMM 128GB, DDR4-2400, CL19-17-17, reg ECC (M393AAK40B41-CTC)

i know, not supported, but is there a chance?

Hard limit of the CPU not the boards, no chance I am afraid.

128gb in a single rdimm !!! Wow !
I only knew of upto 64gb in rdimm, it is 8R though so would not work in lots of systems anyway.

 

[realtomatoes]

i had to look up how much that 128gb stick costs on ebay.
confirmed, it costs an arm.

Oh yeah ! The price is reasonably linear until 32gb rdimm, 64gb rdimm onwards tends to get very expensive.
Anyway an 8 rank dimm is not always that useful, the systems may (do) have limited on number of ranks per channel that mean even if you can use it it's an edge case where your only using 1 dimm per channel.
Most of the 128gb dimm are actually load reduced or 3DS not straight rdimm, I don't know what CPU memory controller support them, E5 v4 does not...

Back to topic I have used 4 x 32gb 2Rx4 rdimm in Xeon-D and that's both the maximum and I think optimal config (unless you have more modest needs when 64gb will do in either 4 x 16gb or 2 x 32gb)

I'm pretty sure the e5 v3/v4 support this as my board specifies support for both 64gb LR and 128GB 3DS LR DIMMs. Which is pretty insane, 1TB in 8 slots is nuts.

 

[Evan]

Very big different supporting LR and regular RDIMM, the on CPU memory controller need to drive the RDIMM, the reason for less capacity is that's hard work and hence the LRDIMM existing.

I tried to look for an update from intel but I don't see any support for those 8R 128GB RDIMM but welcome to be proved wrong as it would be super useful for DIMM limited systems.

 

[Stux]

But Intel is now in the business of charging extra for an M processor if you want more memory, so good luck ever going past the stated maximums ever again on Intel.

 

[m4ntic0r]

i wrote to the supermicro support and they confirmed that this is a hard limit on the xeon d cpus. so although it is not supported, the cpu will never recognize these large dimms.

 

[m4ntic0r]

can anybody help me here?
Problem with Supermicro X10SDV-8C-TLN4F and Turbo Boost :(

 

[SGN]

Can any one share power consumption for 1537 at idle/small load? It would be best to know this value without massive number of addons like drives and gpus.

BTW: I'm going to change my compute node to sth from Xeon D 1500 lineup.
I dont know which CPU should i select. I think 1528 would be ok but i need SFP+ as i dont have 10Gb-T. So need to think more.
It would be VM host with ~10 VMs. Part of them are small and idle but some of them handle small JIRA and Confluence instances which are heavy by design (several users only). Other usecases are small db, Owncloud and Plex (1 stream).
I would like to build it as future proof as possible. For sure i dont want to regret CPU selection.
What do you propose: 1518 or 1537?
Only Supermicro
At this moment Pentium G3220 has around 50% load idle. Plex or heavy Owncloud operations are killing him. Attlasian tools make it slow responsive for longer usage with several users.

 

[hjfr]

I can tell for Xeon D 1518:
My Setup : X10SDV-4C-TLN4F (Xeon D 1518 4c/8T), 16 GB DDR4 ECC Reg RAM (2x 8 GB), one SSD for system and two Seagate IronWolf Pro 7200 rpm for datas. 3 active lan at 1 Gb.
- idle : 40W
- 7z compression on all cores : 68~70W

 

[K D]

2 16gb sticks, 32 gb sata dom, crucial mx300 m.2 ssd. Running pfsense, Idles at 23watts. No heavy load on this system so don't know what the max is.

 

[Evan]

D-1540 (original), from memory... idle was ~28 watts, 128gb ram. Can’t remember what SSD I had in there when I tested it. (Not using probably the most accurate power meter)
