Host sizing recommendations
The NetBackup Snapshot Manager for Data Center host configuration depends primarily on the number of workloads and also the type of workloads that you want to protect. It is also dependent on the maximum number of simultaneous operations running on the NetBackup Snapshot Manager for Data Center at its peak performance capacity.
Veritas recommends the following configurations for the NetBackup Snapshot Manager for Data Center host:
Table: Typical NetBackup Snapshot Manager for Data Center host configuration based on the number of concurrent tasks
Workload metric | NetBackup Snapshot Manager for Data Center host configuration |
|---|---|
Up to 16 concurrent operational tasks | CPU: 2 CPUs Memory: 16 GB |
Up to 32 concurrent operational tasks | CPU: 4 - 8 CPUs Memory: 32 GB or more |
General considerations and guidelines:
Consider the following points while choosing a configuration for the NetBackup Snapshot Manager for Data Center host:
To achieve better performance in a high workload environment, Veritas recommends that you deploy the NetBackup Snapshot Manager for Data Center host in the same location as that of the application hosts.
Depending on the number of workloads, the amount of plug-in data that is transmitted from the NetBackup Snapshot Manager for Data Center host can get really large in size. The network latency also plays a key role in such a case. You might see a difference in the overall performance depending on these factors.
In cases where the number of concurrent operations is higher than what the NetBackup Snapshot Manager for Data Center host configuration capacity can handle, NetBackup Snapshot Manager for Data Center automatically puts the operations in a job queue. The jobs in the queue are picked up only after the running operations are completed.
