when SFF 8639 aka U.2 cables will be available on Market

fbayi — Mon, 29 Jun 2015 14:48:31 GMT

Intel selling p3700/ p3600 / p3500 series 2.5" form factor SSD / NVMe drives.. but there is a problem here although intel 750 series has sff 8639 cables in their boxes , other series has no cables .. and Intel explain the situation because of Enterprise systems has no need.. but is it forbidden to use these high-end ssd 's other than enterprise systems..

first .. why these SSD's has no cable on their boxes

second.. why these U.2 / SFF 8639 cables are not available on market / online stores..

third .. when these cables will be available..

Hello eczanet,

These cables are not available separately for the time being and we do not have any information if they will be available on the market any time soon. Please bear in mind that the Intel® SSD Data Center Family such as the Intel® SSD DC P3500, Intel® SSD DC P3600, Intel® SSD DC P3700 were designed to work with HBA ( Host Bus Adapter). The cable that comes with the 750 would actually work with the SFF-8639 model of the Intel® SSD DC P3500, Intel® SSD DC P3600, Intel® SSD DC P3700.

can you give us few links to that HBA?

i also bought P3700 and was surprised that it comes w/o any cables.

i know other people are buying 750 one only to get that cable. don't you think that's insane? or that was your main marketing idea?

first one is on market

seller answer me via e-mail .. "sff-8639 cable will be available in a few weeks"

idata — Wed, 22 Jul 2015 11:55:23 GMT

great! thanks.

guess i'd give a try the first one.

the only few things i don't really like is that ssd's heatsink will get lower airflow, and i should also use a riser to make all that fit into 1U case.

idata — Wed, 22 Jul 2015 17:45:10 GMT

no, wait.

so with that adapter they used p3600 - http://ecx.images-amazon.com/images/I/610WhHOq5lL._SL1010_.jpg http://ecx.images-amazon.com/images/I/610WhHOq5lL._SL1010_.jpg

and got only ~500mb/s speed - http://ecx.images-amazon.com/images/I/711A78uw4FL._SL1001_.jpg http://ecx.images-amazon.com/images/I/711A78uw4FL._SL1001_.jpg

so that doesn't work good at all

Please keep in mind that Intel does not endorse or recommend the use of unofficial 3rd party adapters.

The Intel® DC SSD P3700/ P3600 / P3500 and Intel® SSD 750 Series are available in 2.5" and Add-in-Card HHHL form factors. The AiC version can be connected directly to a PCIe Gen3 x4 slot and does not require an adapter.

The 2.5 in DC P3xxx drives do not include the U.2 cable since they were originally intended for enterprise usage. Now that some motherboard manufacturers support the NVMe 2.5" SFF-8639 drives using a compatible adapter and cable, we are working to make the supported U.2 cable available, however, we do not have a specific date for this yet.

if this adapter use pci-e 3.0 with 4 lanes... total bandwith must be around 4GB/s ..it looks like just using sata 3.0 interface .. i think pci-e lanes doesnt work at all or passive at the moment.. but i ordered this item before these photos added..when i receive my item i ll give u my results.. i have p3700 ssd..

Hello eczanet, I would like to add some information regarding link bandwidth.

Sata 3.0 link performance is 4.8 Gb/s (Gigabits per second), and the one for PCIe 3 x4 is around 4 GB/s (Gigabytes per second). Since each Byte contains 8 bits, 1 Gigabyte is equal to 8 Gigabits. So there is a considerable difference between SATA 3.0 and PCIe 3.0 x4.

The SATA III (revision 3) interface runs at 6.0Gb/s, with a maximum uncoded transfer rate of 4.8 Gbit/s (600 MB/s). The PCIe 3.0 performance is 7.877 Gb/s (984.6 MB/s) per lane, so, the theoretical maximum for PCIe 3.0 x4 is 31.508 Gb/s (3.9384 GB/s)

You can review the following links for more information:

https://en.wikipedia.org/wiki/Serial_ATA# SATA_revision_3.0_.286_Gbit.2Fs.2C_600_MB.2Fs.29 Serial ATA - Wikipedia, the free encyclopedia

https://en.wikipedia.org/wiki/PCI_Express# PCI_Express_3.x PCI Express - Wikipedia, the free encyclopedia

As you can see in the http://ark.intel.com/# @SolidStateDrives Specifications for Intel® SSD's, PCIe NVMe drives' performance exceeds the maximum possible with SATA 3.0, and high end models like the http://www.intel.ie/content/dam/www/public/us/en/documents/product-specifications/ssd-dc-p3700-spec.pdf Intel® SSD DC P3700 Series actually use a good portion of the PCIe 3.0 x4 bandwidth.

idata — Thu, 06 Aug 2015 17:36:48 GMT

so you got such speeds using that Funtin adapter from amazon and it actually worth the money?

also, since you have the hottest 2tb version of p3700, what's with the heat?

i assume ssd heatsink is very close to the adapter and there's a problem with airflow.

this may become a problem?

Hello Jonathan, Many thanks for all your help here.

You've probably heard that a picture is worth a thousand words.

Lots of Enthusiasts are stumbling on the differences between

the 8b/10b "legacy frame" and the 128b/130b "jumbo frame"

(my choice of nomenclature / not necessarily industry standard).

It would help a lot of you could prepare a simple graphic

comparing the two frame types. We did that here

in our presentation to the Storage Developer Conference:

http://supremelaw.org/patents/BayRAMFive/SATA-IV.Presentation.pdf http://supremelaw.org/patents/BayRAMFive/SATA-IV.Presentation.pdf

(see Page 7).

I believe PC users generally understand that

a byte requires 8 bits. It's the START and STOP bits that

are confusing people. A more detailed graphic could

also illustrate the 128b/132b "jumbo frame" adopted

in the USB 3.1 specification. A good well designed graphic

will help PC users understand how PCIe 4.0 will double

raw bandwidth, using the same 128b/130b jumbo frame.

Keep up the good work!

Is the cable now available from Intel? There has been several months since the last update and all Asus and MSI boards have supported this device since that time using the M2 adapter. I would hope Intel have provided for their customers in this time.

Hello,

This request is still under consideration, however, the cable is not available separately from Intel at this time. Currently, we are not able to confirm if this will change in the future.

The U.2 interface is meant to be used with the Intel® SSD 750 Series (consumer SSD's). Even though it may be possible to find 3rd party cables on the market, these are not tested/validated as a supported configuration for Intel NVMe* Data Center SSD's.

Please check this new document that specifies what ships with the different models of Intel® PCIe NVMe drives:

Thanks Jonathan. What do you do when a customer has an Intel 750 with a broken cable? Do you automatically replace them under warranty?

Re: when SFF 8639 aka U.2 cables will be available on Market

ASouz7 — Wed, 07 Oct 2015 19:30:46 GMT

rfu3,

Unfortunately the warranty is limited to the SSD only. You will need to check with your local reseller.

Re: when SFF 8639 aka U.2 cables will be available on Market

JPitt5 — Thu, 08 Oct 2015 14:06:54 GMT

So if I was to buy an Intel 750 SSD and accidentally break the cable, since there are no retailers for this cable, including yourselves, and there is no warranty on this cable, you would expect me to buy a whole new drive? That's quite an expense for falling foul of a faulty lead. This doesn't quite meet the high level of consumer support I would expect from Intel. Are you sure this is the case?

Hi Aleki_intel, I am in the same boat. I need a replacement cable for my Intel SSD and I dont expect to have to buy a new hard drive just for the cable. Please assist! Thank You
