Hello dand001,
Welcome to Communities.
Apologies but your query is immensely confusing - I will try to clarify what I can.
"2x2 120GIG SSD Intel 530gen"
These appear to be consumer-grade SSDs and are very unlikely to be on the vSAN HCL, thus I assume/hope this is a homelab - understand that this means YYMV and decent performance and/or stability are in no way assumed.
"The Cache Tier is on the same Controller as the default vSANDatastore."
This doesn't make much sense as vsanDatastore is not attached to a controller, here is a basic breakdown of the storage structure of vSAN and what it is composed of:
- Each node(host) contributing storage has 1 or more Disk-Groups.
- Each Disk-Group is composed of 1 Cache-tier device (SSD/NVMe) and 1-7 Capacity-tier devices (all of one type of HDD/SSD/NVMe).
- All Disk-Groups aggregate Capacity-tier storage is pooled to create the vsanDatastore which is accessible from all nodes in the cluster (e.g. 3 nodes each with 1xDG with 2x1TB HDDs as Capacity-tier = 6TB vsanDatastore).
"It seems not be possible to assign a new vSANDatastore to the same Cluster."
Each vSAN-enabled cluster can have exactly 1 vsanDatastore, please if you could attach or PM a screenshot or error message of what you are trying to do that is not working.
Bob
