Scalability
XIV technology is designed to be scalable in all key aspects, including capacity, interfaces, cache, CPU power, and internal bandwidth. The architecture supports each aspect to grow independently, yielding a truly scalable system in both capacity and performance.
The result is a dynamic, future-proof system that is capable of growing to meet changing needs.
Scales in all key aspects - The system is fully scalable with regard to all key aspects of the system, including disk capacity, interfaces, cache, CPU power, and internal bandwidth.
- Embedded in every data module, processing power, cache, host interfaces and their bandwidth grow proportionally to system capacity, increasing linearly the number of applications supported and total throughput, and ensuring no impact of system size on performance during snapshots, caching, or self-healing
- Internal switching capacity stays unchanged regardless of system size, avoiding bottlenecks and ensuring that throughput grows proportionally to capacity. Internal switching capacity is always 4 Gbps per module, ensuring that throughput grows proportional to capacity growth. Avoids bottlenecks regardless of the number of modules
- The system scales incrementally from partial to full rack configurations (6 to 15 modules; 27-79 usable terabytes)
Easy migration and smooth upgradability - The architecture's use of standard components ensures smooth scaling to a maximal configuration, and integration of up-to-date
technologies at any time. The XIV system offers seamless, effortless, and non-disruptive hardware upgrades, with automatic load balancing between new and old hardware.
- Scales to any configuration with no need to reconfigure
- Automates the transfer of data to new hardware, automatically load-balancing all the data across new and existing hardware
- With its grid architecture and use of standard components, can capitalize on the latest advances in storage component technologies and supports a mix of hardware technologies
- Supports non-disruptive inter-family hardware and firmware upgrades (code load)
- Mirrors all volumes in the system
