Table 1 shows the supported configuration for an SSD cluster.
Supported options | |
Cluster size | 4 to 6 nodes |
EC2 instance type | All nodes in a cluster must have the same instance size. The supported instance sizes are:
Note: You must run a Proof of Concept (PoC) if you intend to use m5d.24xlarge or i3en.12xlarge EC2 instance types. For details, contact your Dell account team. |
EBS volume (disk) type | gp3 |
EBS volume (disk) counts per node | 5, 6, 10, 12, 15, 18, or 20 |
Single EBS volume sizes | 1 TiB–16 TiB |
Cluster raw capacity | 24 TiB–1.6 PiB |
Cluster protection level | +2n |
Note: all criteria in this table must be met. Therefore, not all combinations of cluster size, volume count, and single volume size are supported. For some combinations of cluster size, volume account, and single volume size, the total cluster raw capacity may fall outside the maximum supported cluster raw capacity. For example, for a 6-node cluster, if each node contains 20 volumes, and each volume size is 16 TiB, the final total cluster raw capacity is 1,920 TiB, which exceeds the maximum supported raw capacity. Therefore, this combination is not supported.
See Appendix A: supported cluster configuration details for all supported combinations.
