Applications

ExpressSAS RAID adapters add high-performance RAID data protection to direct-attached SAS and SATA JBOD storage. They are an ideal connectivity solution for high-performance

media and entertainment and general IT environments. ExpressSAS 6Gb/s SAS/SATA RAID adapters deliver affordable host-level RAID for high-bandwidth workflows such as digital

content creation, streaming video, transactional databases, and email and Web servers.

Advanced Data Streaming (ADS

™)

Latency-management technology that controls the

acceleration of data transfers to move large amounts of

data faster and more efficiently.

DriveAssure

™ Technology

Drive assessment and latency management technology

that minimizes the likelihood of RAID groups becoming

degraded or taken offline due to slow drives, ensuring

uninterrupted access to data.

CacheAssure™ Technology

Flash-based protection module providing a

maintenance-free solution that safeguards against the

loss of cached data during a power or system failure.
