[Wolves] Storage advice.

[John Alexander]

 Hi Simon, reading this and looking at several of the replies it seems that everyone takes something different from the discription. Are these VMDKs on SANs nor not ..not said  but important as soft raiding on the VM storage what is RAID'd on the SAN is redundant and still gives you the same filure domain as Chris says.Can you say more about the application?Personally I think a better solution would be based on some knowledge of what they are trying to solve.
If you dont know,it may be good to get back to the customer.

 Hi,
Odd position I'm in at day job. 
I have a VM (VMWare) running Oracle Linux 9, with two 50tb VMDKs attached. 
The issue is that I need to span them, and it'll store a lot of tiny files (circa 80Tb in 2-3mb files), with a high daily rate of change. 
Choosing the right method to achieve this is proving a challenge, when I've got to get this going this week. So testing is limited. 
I can't have a single large VMDK due to a 62Tb limit in VMWare. 
I can just use ext4 and LVM, or Oracle Linux likes Btrfs. ZFS is provisionally out unless I get a third 50Tb disk, for ZRAID+1.
Opinions? 

Or I can do some basic tests and report results if anyone is interested?
ThanksSimon--
