As you have 10bay backplane, your SAS cable connection should be as mentioned on of "Figure 4. Cabling diagram—2.5-inch (x10) hard drive systems" below link. The same connectivity is applicable regardless of whether you have H330 Mini or H730 Mini. H710 controller not supported on R630 [URL]  You need to have below SAS cable for this connection
I have 3 x R630 10-bay servers which originally came with MPT Fusion RAID cards (LSI2008 chipset) which isn't supported by VMware ESXi 7. I'd like to configure these for my homelab with vSphere 7/VSAN so looking at options to replace the MPT RAID with something else. What I can't work out is - if I buy some PERC H710 Mini controllers (which should work fine on the internal RAID slot on the R630 motherboard), what cables do I need? I'm guessing that the motherboard SFF-8643 headers (near the onboard RAID slot) are used and just need to be connected to the SFF-8643 headers on the storage backplane? It looks like if I went instead with the H330 Mini or H730 Mini these need a custom Dell PERC cable from the Mini PCB to the SFF-8643 headers on the storage backplane, but I can't see any connectors like this on pictures of the H710 Mini. Could someone confirm that R630 10-bay to H710 Mini just needs 2 x SFF-8643 to SFF-8643 cables? I'd probably rather go with a plain H330 Mini for VSAN (since I only need JBOD disks), but the cable prices online are pretty bad and it would be cheaper to go with the H710 if it doesn't need the custom PERC cables. Thanks in advance, Jon.
