In addition to single-node cliques, on AWS the primary cluster supports multi-node cliques.
You can deploy multi-node cliques on AWS by selecting Provisioned IOPS SSD (io2 Block Express) from the Advanced options > Storage type while creating the environment, see Getting Started: First Sign On by Organization Admin .
Other limitations and considerations for VantageCloud Lake primary cluster deployment:
- Both Standard and High IO instance family support both GP3 and IO2 block storage.
- Gp3 is only supported for Node Count < 10 for all instance types and sizes.
- io2 is supported for Node Count 2-128 for all instance types and sizes.
- io2 IOPS is required only when Storage Type = io2; however, the io2 IOPS provisioned with io2 varies based on instance size of VantageCloud Lake primary cluster.
- io2 storage has additional cost of io2 IOPS on AWS.
When configuring your environment using the VantageCloud Lake Console, these are the defaults:
- Deployments with 10 or more instances default with provisioned IOPS SSD (io2 Block Express) on the primary cluster.
- Deployments with fewer than 10 instances default to general purpose SSD (gp3) on the primary cluster.
Block storage expansion, scaling up and down on the primary cluster is supported.
- To add block storage expansion to the primary cluster, you must submit a request. See Block Storage.
- To scale your primary cluster up or down, you must submit a request. See Scaling Primary Cluster Up and Down.
Benefits:
- System availability regardless of infrastructure failure.
- Faster recovery. From 15-20 minutes to equal or fewer than 3 minutes approximately.
- Mitigate impact to system level availability due to storage volume failure by offering higher durable storage to the customer.
