Scalable in All Key Aspects

XIV technology scales in all key aspects, including capacity, cache size, switching, and processing power:

• Linear cache growth - The system's cache size increases linearly with disk capacity, as every data module contains its own cache. The system's cache bandwidth toward disks and hosts increases linearly with cache size.
• Proportional interface growth - The number of host interfaces, as well as the bandwidth between them and the data modules, can grow in proportion to the system's capacity. This provides a proportional increase in the number of supported applications and total throughput.
• Constant switching capacity - Internal switching capacity is maintained at 4 Gbps for each module and, therefore, never creates a bottleneck regardless of the number of modules. This ensures that throughput grows proportionally to capacity.
• Embedded processing power - Processing power is embedded in each module; as a result, system size has no adverse effect on snapshot management, caching, or rebuild performance.
