Reddit mentions of CableCreation Internal Mini SAS SFF-8087 to Right Angle SFF-8087 Cord, Internal Mini SAS to Mini SAS Cable, Compatible with RAID or PCI Express Controller, 2.5FT /0.75M

Just buy any generic 8087 to 8087 right angle cable, https://www.amazon.com/CableCreation-Internal-SFF-8087-36Pin-Right/dp/B01KFEVQ4E/ref=sr_1_2?s=electronics&ie=UTF8&qid=1502054140&sr=1-2&keywords=8087+to+8087+right

You're correct. 6/i is slow, limited to drives 2TB or smaller, and doesn't have true IT mode. Its a good card to keep if (1) you don't care about software RAID, and (2) have spinners 2TB or less.

The H200 is a great card. You can leave it in IR mode if you want hardware RAID or flash IT mode if you want software RAID. Will work with any drive.

You'll need new cables. These are the right ones for an LFF model.

On my R710, I bought and flashed an H200 using:

I have flashed a few, and had to flash them in another box. I never could get my r710 to cooperate with that part. In the other machine, it took 20 minutes and went without a hitch.

As others mentioned, with a non standard bios you are looking at putting it in another slot. Here are the cables I'm using and they fit well: https://www.amazon.com/gp/product/B01KFEVQ4E/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1

Using proxmox, if you want to pass the card through to a VM, here is what you are looking at:

If memory serves, I did have to take the step to allow unsafe interupts from the "IOMMU interrupt remapping" section.

I have this cable from Amazon in my R710

I have a similar build for freenas. I got a m1015 and needed a cable like this: CableCreation Internal Mini SAS(SFF-8087) 36Pin Right Angle Male to Internal Mini SAS (SFF-8087) 36Pin Male Cable, 0.75 Meter https://www.amazon.com/dp/B01KFEVQ4E/ref=cm_sw_r_cp_apa_eHCDAb964EF7P

Something like this?

I saw some people had issues with their Norco backplanes, but mine has been good. For DAS setup, you'll need a powerboard (or some cheap motherboard should work?) to turn on the power supply?

The mid fan wall is a little tight to the backplane connectors so I went with the right angled ones.

I originally bought a Y splitter for the fans, but it was loose fitting, so I swapped it out for one of these.

If you want a semi "Professional" look then you'll need a bracket coming out of each case plus cables to connect them externally, plus more internal cables $$$... This is where a DIY DAS starts nickel and diming you. The other option is just running the SFF-8087 cable coming off of the expander thru the cases and snake it into your Proliant+9211 card. With that scenario the expander would have to be secured near the back of the case so a connecting cable would be long enough.

Another thing is that expander card has dual aggregation, so you can double its speed if you have 2x 8087 coming out of one expander, but then you can only have 16 drive input. I did the math in the past (not sure if it was correct tho), but I think a single link expander will be the limiting factor if you try to run all +16 drives at once. While not an issue for regular access, it would slow down a parity/backup type process that accesses multiple drives at once (Snapraid comes to mind). Of course I guess not an issue if you run this while your sleeping or whatever, but overall 20-24 HDD on one expander should be fine'ish...

These are the exact cables I bought (buy 2) for my R710 II LFF to connect my H200 and it works perfectly.

I ordered two of these - CableCreation Internal Mini... https://www.amazon.com/dp/B01KFEVQ4E?ref=ppx_pop_mob_ap_share

They're a bit long but they work. Make sure you order the correct angle. Mine were right angle. The card can be updated with the latest Dell firmware and it can be placed in the storage slot. This allows drives of higher capacity. Currently have two 3tb drives running and will be adding a couple few 8s in a few days.

I'm assuming your 710 is the LFF with 3.5in drives?

WD Reds, currently 1 4TB and 2 3TB installed, 3 more 4TB I haven't moved over yet until I can get it working.

​

Yes they worked previously on this card when the card was installed in an old 2500K desktop. Prior to this switch they were in a Rackable 24 bay chasis connected with external SAS cable to a SAS9200-8e H3-2560-02G.

Had to purchase new mini SAS cables for this as I didnt have any https://www.amazon.com/gp/product/B01KFEVQ4E/ref=ppx_yo_dt_b_asin_title_o01_s01?ie=UTF8&psc=1

​

TLDR only new components to this setup are the R720 and the mini SAS cables, everything else was previously working on another build.

These will work.

I went with right angle cables as well. These are the ones I used.

You can pick up sas cables that work with the h700 from Amazon, you don't necessarily need the dell ones.

I got two of these ( linky ) and they work just fine, and fit the LFF backplane.

These are what I ordered a few weeks ago, they work great in my R710+M1015. They are out of stock now but you might be able to lookup the cable on ebay by the same mfg.

https://www.amazon.com/gp/product/B01KFEVQ4E/

These cables work as well if anyone is looking for some on amazon.

I have one in my R720XD with flexbay, you only need one card

as for cable length i tried finding my purchase and i am fairly sure i went with 2 of these right angle ones:

https://www.amazon.com/gp/product/B01KFEVQ4E/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&th=1

I don't think that's the right cable (though it might work). For my H700->R710 backplane, I needed right-angle cables that looked like this (these are way too short though):

https://www.amazon.com/CableCreation-Internal-SFF-8087-36Pin-Right/dp/B01KFEVQ4E

H310 and H700 should use the same cables

Dell PN: P110M is what I ordered, which you need two. And they worked perfectly in my R710 to go from an H700 to the 3.5" backplane. I mentioned this before, and someone said those might be too short, but it's what I ordered and they worked.

Edit: oops, that one is from China too. But that's at least the right Dell Part Number to search for.

I tried the amazon ones then a left and right set from eBay. They were all wrong. I just got straight ones in the end.

It’s amazon.ca I hope that’s ok.

I was just recently/currently in the same boat. I purchased a used r710 to make into a plex server. I bought a H310 on ebay (paid a premium and bought a preflashed IT version so I wouldn't have to mess around doing it myself). I guess I don't have any real reason I bought the H310 over the H200, from what I read they both will work as long as they are flashed into IT mode. I just had to buy new cables and install them. I have only tried it with a 1 TB hard drive in unraid and it seemed to work great. Ultimately I went with unraid simply because I wanted to be able to add drives easily as my library grew and have a parity drive- both of which unraid does.

These are the cables you need. They were $12/pair a couple days ago, but $16 still isn't bad.
