High-availability systems are essential to nearly all businesses regardless of size or industry. When systems running business-critical applications such as transaction processing, Web serving or electronic commerce are not accessible, the results can be lost revenue, lost productivity and reduced customer satisfaction.
“A critical goal of Windows Server 2012 is delivering high availability to a volume market, and LSI has been key in this effort,” said Thomas Pfenning, general manager, File Server Foundation, Microsoft. “The combination of LSI® HA-DAS with Windows Server can provide SMBs and cloud datacenter providers with a low-cost and easy-to-manage option for meeting their high-availability requirements.”
Traditional HA solutions ensure continuous application availability through server clustering and shared-node storage area network (SAN) connections that build redundancy into a cluster and eliminate single points of failure. LSI is pioneering HA-DAS solutions that lower the cost and complexity of HA solutions by providing fully redundant, shared-node storage and application failover without requiring storage networking hardware. LSI’s HA-DAS solutions also reduce latency compared to SAN-based solutions, helping to accelerate storage I/O performance and speed applications.
“LSI HA-DAS solutions are designed to bring SAN-like shared storage and application failover capabilities to DAS environments to provide customers with a low-cost and easy-to-manage and -deploy solution for ensuring business-critical applications remain up and running during server failures,” said Bill Wuertz, senior vice president and general manager, RAID Storage Division, LSI. “We’re excited to be collaborating closely with Microsoft to bring HA-DAS solutions to the marketplace.”
LSI is demonstrating its HA-DAS solutions based on leading MegaRAID® controller and intelligent HA-DAS technology. The demo utilizes two servers with two internal LSI MegaRAID controllers running HA-DAS firmware connected to twenty-four 2.5-inch SAS drives through an LSI SAS expander. The demo showcases how LSI HA-DAS solutions can bring simpler, lower-cost shared storage and failover capabilities to DAS environments.
