Storage Spaces Direct - Why the tiny capacity?
I don't understand why the new 2019 Storage Spaces Direct won't even support a single 90 bay JBOD loaded with 8TB drives.
I am currently testing the addition of that unit into our infrastructure using regular storage spaces. It runs fine. Dual Parity writes of 75 MB/sec are sad, but Mirror writes at 1,600 MB/sec are really nice. Everything seems to work fine.
I've looked at the Windows 2019 limits, and the storage spaces direct raw capacity per physical server is 400 TB. What drives this? I'm trying to sell the idea of turning a customer's 1.5 PB storage space infrastructure over to a cluster of storage spaces direct. However, as currently specified, we can't do that with 4 servers and 4 90 bay JBODs.
