-#### Calculating EC Pipeline Limits
-
-The target number of open EC pipelines SCM aims to maintain is calculated dynamically for each EC replication configuration (e.g., RS-6-3, RS-3-2). The calculation is based on the following two properties, with the final target being the greater of the two resulting values.
-
-*   `ozone.scm.ec.pipeline.minimum`
-    *   **Description**: The guaranteed minimum number of open pipelines to maintain for each EC configuration, regardless of other factors.
-    *   **Default Value**: `5`
-
-*   `ozone.scm.ec.pipeline.per.volume.factor`
-    *   **Description**: A factor used to calculate a target number of pipelines based on the total number of healthy volumes across all datanodes in the cluster.
-    *   **Default Value**: `1.0`
-
-**Calculation Logic:**
-
-SCM first calculates a volume-based target using the formula:
-`(<pipeline.per.volume.factor> * <total healthy volumes>) / <required nodes for EC config>`
-
-The final target number of pipelines is then determined by:
-`max(<volume-based target>, <pipeline.minimum>)`
-
-**Example:**
-
-Consider a cluster with **200 total healthy volumes** across all datanodes and an EC policy of **RS-6-3** (which requires 9 nodes).
-*   `ozone.scm.ec.pipeline.minimum` = **5** (default)
-*   `ozone.scm.ec.pipeline.per.volume.factor` = **1.0** (default)
-
-1.  The volume-based target is: `(1.0 * 200) / 9 = 22`
-2.  The final target is: `max(22, 5) = 22`
-
-SCM will attempt to create and maintain approximately **22** open, RS-6-3 EC pipelines.
-
-**Production Recommendation:**
-
-The default values are a good starting point for most clusters. If you have a very high number of volumes and a write-heavy EC workload, you might consider slightly increasing the `pipeline.per.volume.factor`. Conversely, for read-heavy workloads, the default minimum of 5 pipelines is often sufficient.
