vSAN and RAID pass-through

I'm configuring a VMware vSAN  on a few Dell PowerEdge R720s with a PERC H710 Mini RAID Controller (embedded) running vSphere 6.5.  I'm trying to surface the drives (2 SSD and 6 HD) but there are restrictions on the H710 not allowing me to convert to non-RAID.  VMware documentation indicates that drives must be set up in a "pass through RAID" configuration.  So, do I get another RAID controller that allows for no-RAID drives or is there a way of creating Raid 0 drives or can I mirror the 2 SSDs (RAID 1) and RAID the other 6 HDs.  Maybe I'm old school but I tend to trust controller RAID more than software raid, but it's required so not sure I can get around it.

H710 does not support JBOD mode, you will have to create each individual disk as RAUD0 instead.

I hear that the H330 is great for this use case.

„H330 is great for this use case” -> there are two different controllers, the H330 and the HBA330. The HBA330 is a good SAS Controller often used in current vSAN ready configs. The H330 is still a simple RAID Controller. So if a new Controller is an option, I would go for the HBA330.

But you can also set the disks as individual RAID0 in your current controller (andyalder already provided that solution)

if you need a supported solution, please verify all components on the HCL

Is this for experimentation (e.g. Lab) or Production ?

If for serious production, you will want to ensure that all your components are on the HCL for vSAN.

A non-HCL component which was recently sent from a vendor by Support (because it failed) and it took down a vSAN implementation, and later it was found the component, which was a SSD was not on the HCL.

Vendor had not noticed this was a vSAN implementation!

(yes VMware vSphere vSAN is troublesome!)
