The following figure shows the major sizing drivers for each TrueSight Capacity Optimization component:
TrueSight Capacity Optimization sizing drivers
A major sizing driver for the TrueSight Capacity Optimization infrastructure is the required throughput for processing collected samples. One TrueSight Capacity Optimization unit refers to one million samples per day. For example, 20 million samples per day are also referred to as 20 TrueSight Capacity Optimization units.
An entity is a managed system or device whose performance data is collected, such as a physical stand-alone server, a partition on a server, a virtual server, a database instance, a storage element, or a network element.
The following table shows how to translate the number of managed entities, metrics, and time granularity of the samples into the number of samples per day.
Number of managed entities | Average number of metrics per entity | Time granularity of the samples | Samples for 24 hours |
---|---|---|---|
1,250 | 40 | 1 hour | 1.25 million |
2,500 | 40 | 1 hour | 2.5 million |
5,000 | 40 | 1 hour | 5 million |
1,250 | 40 | 15 minutes | 5 million |
2,500 | 40 | 15 minutes | 10 million |
5,000 | 40 | 15 minutes | 20 million |
Note
The preceding table does not take into account business driver metrics. Estimate the number of business driver metric samples that have to be processed on a daily basis as 10% of the overall managed entity metric samples per day.
The following topics describe guidelines and recommendations for sizing each TrueSight Capacity Optimization component, based on average utilization scenarios. All sizing values are provided as general guidance.
The following table shows TrueSight Capacity Optimization deployment sizes according to these two major sizing drivers:
| Small | Medium | Large | X-Large | XX-Large |
---|---|---|---|---|---|
| <= 20 M rows | <= 40 M rows | <= 80 M rows | <= 160 M rows | <= 600 M rows |
Oracle | 4 cores 8 GB RAM | 4 cores 16 GB RAM | 8 cores 32 GB RAM | 16 cores 64 GB RAM | 64 cores 128 RAM |
Postgres | 6 cores 12 GB RAM | 12 cores 24 GB RAM | 24 cores 48 GB RAM | N/A | N/A |
Data Hub1
| 4 cores 8 GB RAM | 4 cores 8 GB RAM | 4 cores 16 GB RAM | 8 cores 32 GB RAM | 32 cores 128 GB RAM |
1 - A deployment can have only one Data Hub.
