As enterprises demand more speed and agility from their infrastructures, the performance advantages of flash are critical for addressing the requirements of next-generation businesses. In building an enterprise-ready all-flash solution, we knew our architecture had to solve some of the technical challenges that hadn’t been successfully addressed in the past. This included resiliency, data protection, and scalability.
One of the critical areas we’ve been able to address with a breakthrough solution has been in extending the endurance of flash technology. Endurance is a critical factor in making flash enterprise ready. In fact, one vendor recently released a study in which 77% of respondents said that they believed that the endurance of flash memory is the key to the widespread adoption of SSDs in the enterprise.
How have we been able to achieve new levels of endurance? It all starts, of course, with SPEAR (Scale-Out Performance and Resilience Architecture), which is the foundation for our recently introduced fourth-generation K2 all-flash storage array. As a true scale-out architecture, SPEAR enables us to spread the load very intelligently to maximize flash endurance. Here are some of the keys:
SPEAR utilizes a system-wide write cache that eliminates hot spots.
By using cache for writes, SPEAR is able to minimize the number of writes and distribute writes across all flash media in the system. The system never writes to the same place twice.
SPEAR’s efficient management of metadata eliminates writes to the flash during updates and facilitates space-efficient snapshots that do not incur additional writes.
K2 deploys the highest enterprise-grade SSDs with advanced flash management capabilities that optimize the endurance of the flash.
Writes in K2 are always sequential to the flash media.
SPEAR uses advanced error correction
By building all of these features and functions into SPEAR, Kaminario has been able to prolong the endurance of flash far beyond the spec limits of flash manufacturers, and beyond the limits of almost every competitor building all-flash arrays. When it comes to endurance for enterprise-ready flash arrays, we continue to lead the industry.
