Type of optical breakout cable for front-end networking of Isilon H500 nodes

I have 4 x Isilon H500 Gen 6 nodes incoming.  According to the BOM, the Front End networking optics are listed as "Transceivers/Optic/SFP+/SR/10GbE/2 GEN6" (part number: 851-0296).

Looking to connect the Front End to existing Cisco Nexus 2348TQ switches.  These are 48 port 10GB Base-T switches (I know the Base-T ports can not be used) with 6 x 40GB QSFP ports. I'm looking to use a breakout cable (40GB QSFP to 4 x 10GB SFP+) to connect the Isilon nodes to the QSFP ports on these Cisco switches.

Need to know:

1). Does it matter if I use a DellEMC or Cisco Cable?
2). Type/Model of cable is needed?  From a DellEMC perspective, it looks like i would need something like an AOC-QSFP-4SFP-10G-xM (10M or 30M).  From a Cisco perspective, it looks like I would need something like a QSFP-4X10G-AOC (1M, 2M, 3M, 5M, 7M or 10M).

Any help here is much appreciated as apparently I can not open an SR with DellEMC with out calling and speaking to Support (can't create SR online, or through live chat).  Which I supposed I will do if it comes to it.

Thanks!
