5.2 EonStor CS Storage Configuration
The followings are restrictions of storage configuration:
1.
The disk slots of EonStor CS must be fully inserted to configure, except for CS 4014U. For CS 4014U, a
minimum of 6 drives will be sufficient. Note that NVMe SSDs should be purchased together with the
storage appliance.
2.
EonStor CS cluster can scale-out up to 144 storage nodes.
3.
EonStor CS does not support the expansion enclosure configuration with hybrid form factors. Once you
select the form factor of the expansion enclosure, the system will select the expansion enclosure model
that can be used by the node. For instance, if EonStor CS HDD node connects the JB 3016 for scale-up
expansion, only the JB 3016 can be selected for the expansion enclosure in the future.
4.
If one of the storage nodes in the storage pool is connected to the expansion enclosure for scale-up
expansion, it is recommended that you balance storage capacity of all nodes in the pool to avoid
excessive I/O load on some nodes.
Scale-up Expansion Enclosures must have the same configuration with the nodes
