Application nodes & cluster size


A ZebClient cluster

Example of a Medium sized ZebClient cluster.

ZebClient cluster

Number of application nodes

ZebClient has been designed to support scale-out application use cases. Once a cluster size has been decided on and deployed, application nodes can be dynamically provisioned or decommissioned to meet the needs of the use case. For a High Performance scale-out case, a large number of Application nodes can be deployed to serve data access from multiple nodes, for parallel workloads. All ZebClient cluster data will then be accessible from each Application node, with the first read operation having Warm tier performance and consecutive read operations supporting Hot tier performance.

Selection of cluster size

The number of cluster nodes and the number of disks/memory modules is set by selecting Cluster Size of ZebClient cluster for deployment in Table Cluster below. Performance is best scaled for large clusters from 6 up to 10 Application nodes using the Large cluster deployment. For a ZebClient cluster having more than 10 Application nodes deployment, contact Zebware for a custom configuration.

Both node, disk redundancy and performance needs to be considered for the deployment. All default Cluster Size deployments of ZebClient in Table Cluster have both node and disk redundancy if deployed on separate nodes without a single point of failure.

Table Single

Cluster Size Nodes No Warm Disks Hot Disks Node redundancy Disk redundancy
Single 1 1 2 0 0

Cluster: Small, Medium, or Large ZebClient cluster. Single is on one node deployment.

Nodes: Number of nodes for the deployment of ZebClient cluster Warm tier

Warm: Total number of Warm disks

Hot: Possible number of Hot disks/memories for acceleration on each Application node. The total number of Hot disk/memories in the cluster is Hot x number of Application Nodes

Disks and memories to be used

  • Warm tier disk size is default 1 TB, larger disks are better.
  • Hot tier memory/disk size is default 1/10 of Warm tier disks. Choose high-performance disks/memories for the Hot tier. The total number of Hot disk/memories in the ZebClient cluster is Hot x number of Application nodes.
