+Multilevel Cache System Implementation
+Tiers: In-Memory -> SSD -> HDD
+Uses LRU (Least Recently Used) eviction policy with cascading evictions.
+
+Design Patterns Used:
+- Chain of Responsibility: Each cache tier delegates to the next tier
+- Strategy Pattern: LRU eviction strategy can be swapped
+- Template Method: Common cache operations with tier-specific behavior
