Storage Patterns

Local Storage Optimization

Rook Configuration

apiVersion: ceph.rook.io/v1
kind: CephCluster
metadata:
  name: edge-storage
  namespace: rook-ceph
spec:
  dataDirHostPath: /var/lib/rook
  mon:
    count: 3
    allowMultiplePerNode: false
  mgr:
    count: 1
  storage:
    useAllNodes: true
    useAllDevices: false
    config:
      storeType: bluestore
      databaseSizeMB: "1024"
      journalSizeMB: "1024"

Data Locality

StorageClass Configuration

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: edge-local-storage
provisioner: kubernetes.io/no-provisioner
volumeBindingMode: WaitForFirstConsumer
reclaimPolicy: Retain

Cache Management

Redis Edge Cache

apiVersion: redis.redis.opstreelabs.in/v1beta1
kind: RedisCluster
metadata:
  name: edge-cache
spec:
  kubernetesConfig:
    image: redis:7.2
    resources:
      requests:
        cpu: 100m
        memory: 128Mi
      limits:
        cpu: 500m
        memory: 512Mi
  storage:
    volumeClaimTemplate:
      spec:
        accessModes: ["ReadWriteOnce"]
        storageClassName: edge-local-storage
        resources:
          requests:
            storage: 5Gi
  redisConfig:
    maxmemory: "400mb"
    maxmemory-policy: "allkeys-lru"
    activedefrag: "yes"

Best Practices

1. Storage Architecture

   • Data tiering

   • Cache hierarchies

   • Replication strategies

   • Backup policies

2. Performance Optimization

   • I/O scheduling

   • Buffer management

   • Cache warming

   • Write coalescing

3. Data Management

   • Lifecycle policies

   • Retention rules

   • Sync strategies

   • Cleanup procedures

4. Reliability

   • Error handling

   • Data recovery

   • Consistency checks

   • Health monitoring
