Not supported: at least minimum number of drives
If two media types exist:
Node 1 Node 2 Node 3
2 × SSD for cache 2 × SSD for cache 2 × SSD for cache
3 × HDD for capacity 3 × HDD for capacity 3 × HDD for capacity
This is not supported. Nodes with two media types drives should have 2 SSD drives for cache and 4 HDD drives for capacity.
Supported: at least minimum number of drives
If two media types exist, supported configurations are:
Node 1 Node 2 Node 3
2 × SSD for cache 2 × SSD for cache 2 × SSD for cache
4 × HDD for capacity 4 × HDD for capacity 4 × HDD for capacity
This is supported. Nodes with two media types drives should have 2 cache drives (SSD/NVMe/AEP) and 4 capacity drives
(HDD/SSD/NVMe).
Not supported: drives with different bus protocol
The first two nodes use SSD drive with SAS bus protocol but the third node uses SSD drive with SATA bus protocol.
Node 1
Node 2 Node 3
SSD with SAS protocol SSD with SAS protocol SSD with SATA protocol
The first two nodes use SSD and HDD drives with SAS bus protocol but the third node uses HDD drive with SATA bus protocol.
Node 1
Node 2 Node 3
SSD with SAS protocol HDD with SAS protocol HDD with SATA protocol
These are not supported. Drives across nodes should have the same bus protocol for symmetrical configuration.
Not supported: drives with same capacity and different count
The first two nodes use 2TB SSD and the last node uses 3TB SSD. Every node has total 4 SSD.
Node 1
Node 2 Node 3
4 × 2 TB SSD 4 × 2 TB SSD 4 × 3 TB SSD
This is not supported. All drives of each media type (SSD/NVMe/HDD) should be of the same count and capacity.
Not supported: at least one same RDMA network adapter present in all nodes
The first two nodes use Qlogic network adapter and the last node uses Mellanox network adapter.
Node 1
Node 2 Node 3
