ATTO ExpressSAS® SAS/SATA RAID HBAs are engineered with distinctive intelligence and core architectural features that makes them the premier choice for transferring data with greater speed and reliability. Whether you need connectivity for direct-attached disk or tape storage, you can trust ATTO's time-tested RAID stack to provide you with high-performance data integrity.
ATTO ExpressSAS® RAID HBAs featuring Adaptive Path Optimization™, have built-in intelligence to recognize that there are two paths to every drive, and will direct I/O accordingly. If a path to a controller goes down, or is taken off-line for maintenance, I/O will automatically be routed down the remaining path. If the path is restored, the adapter automatically reconfigures to send data down both paths. ATTO automatically senses the paths to the storage, configures primary and secondary access on a disk-by-disk basis and balances I/O so that all paths are running as efficiently as possible.
ATTO ExpressSAS® RAID HBAs featuring CacheAssure™ use supercap technology instead of a battery to protect your cached data. Save time and money by eliminating the need to install, monitor, maintain, dispose, and replace batteries, plus with CacheAssure™, taking down the system for battery replacement is no longer a requirement.
ATTO ExpressSAS® RAID HBAs are designed to maintain full performance in degraded mode and to minimize downtime with 50% faster builds. ExpressSAS® HBAs combine 6Gb/s SAS speeds and x8 PCI Express 2.0 with powerful hardware and software elements to manage latency in real-time environments. ATTO exclusive Advanced Data Streaming (ADS™) and DriveAssure™ technology minimizes data transfer interruptions while maximizing CPU processes to deliver smooth and reliable data transfers and the highest consistent performance.
ATTO ExpressSAS® RAID HBAs provide up to 50 percent faster read performance compared to competitive products. Additionally, ExpressSAS® RAID HBAs deliver excellent write performance, especially at larger block transfer sizes. It allows users to achieve the highest I/O and data throughput for the complete spectrum of applications, including advanced video, backup and transactional database.
Drive assessment and latency management technology is built into ATTO ExpressSAS® RAID HBAs. DriveAssure™ provides bounded latency through proprietary algorithms and user controls to prevent premature drive failures and slow downs, ensuring uninterrupted access to data. Through periodic drive scans, DriveAssure™ searches for bad sectors or slow spots in your disk drives and repairs them without failing the drive, preventing the loss of critical assets
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.
ATTO ExpressSAS® RAID HBAs 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.
ExpressSAS® RAID HBAs offer driver support for Windows®, Linux®, and Mac OS® X, providing a single connectivity solution for customers with heterogeneous operating system environments.
