Efficiently Share Memory
ATTO 12Gb ExpressSAS host bus adapter (HBA) drivers are optimized to ensure that driver resources are located close to the system I/O. In addition, they support NUMA-aware applications and operating systems. NUMA is a system design that allows multiple processors in the same server to efficiently share memory. This reduces latency and increases I/O performance - especially important for data mining, business analytics and other processor-intensive applications.
Protect data integrity
ATTO ExpressSAS HBAs feature Power Center Pro provides RAID 0, 1, 1e and 10 capabilities for internally-mounted disk drives. This feature is often required for end users often need to add a level of performance or protection to a boot drive group. With Power Center Pro RAID, you can protect a boot group against drive failure, or if you'd like to achieve faster boot times, you can bundle several drives together to improve overall performance. Additionally, Power Center Pro may be used to set up a server storage for general use. These are just a few examples of the many ways to use Power Center Pro to provide a cost-effective option that adds performance and protection to your storage architecture.
Increase your bottom line
ATTO ExpressSAS HBAs consume up to 40% less power than competitive offerings and delivers a significant reduction in data center electric and cooling costs.
