+To support pod level LLC/MBA limit, we add a new annotation, the annotation key is `node.koordinator.sh/resctrl`.
+
+Below is the example value of the annotation. schemata defines all caches' configuration. schemataPerCache will define specific cache's configuration which will not use all caches' configuration. 
 ```go
-type Resctrl struct {
-    L3 map[int64]int64
-    MB map[int64]int64
+{
+  "LLC": {
+    "schemata": {
+      "range": [20,80],
+    },
+    "schemataPerCache": {
+      {
+        "cacheid" : 0,
+        "schemata": {
+          "range": [20,50],
+        }
+      },
+      {
+        "cacheid" : 1,
+        "schemata": {
+          "range": [20,60],
+        }
+      },
+    },
+  },
+  "MB": {
+    "schemata": {
+      "percent": 20,
+    },
+    "schemataPerCache": {
+      {
+        "cacheid": 0,
+        "percent": 20
+      },
+      {
+        "cacheid": 1,
+        "percent": 40
+      },
+    },
+  }
 }
 ```
 
-Below is the example of annotation. 80 means 80% of LLC. 60 means 60% of MB.
+schemata and schemataPerCache are defined as below structures:
+
+```go 
+type SchemataConfig struct {
+    Percent int `json:"percent,omitempty"`
+    Range []int `json:"percent,omitempty"`
+}
+
+type SchematePerCacheConfig struct {
+    CacheID         int "json:"cacheID,omitempty""
+    SchemataConfig  `json:",inline"`
+}
+```
 
+The annotation value finally will be parsed as below which define LLC and MB configuration:
 ```go
-{
-  "L3": "80"
-  "MB": "60"
+type Resctrl struct {
+    LLC map[int]int64
+    MB map[int]int64
 }
 ```
