LSI Launches New Generation of High-Performance RAID Controller Cards Based on 6Gb/s SAS Technology
MILPITAS, Calif., July 28, 2009 – LSI Corporation (NYSE: LSI) today launched in the channel a new generation of high-performance MegaRAID® SATA+SAS RAID controller cards based on 6Gb/s SAS technology. With innovative new 6Gb/s SAS product features and support for SATA, SAS and solid-state drives (SSDs), the MegaRAID 9200 series controllers provide small- to mid-sized enterprises with superior levels of RAID performance and scalability for internal and external storage.
The MegaRAID 9200 series controllers, featuring the LSISAS2108 6Gb/s SAS RAID-on-Chip (ROC), double the data transfer rates of their 3Gb/s predecessors to deliver industry-leading performance with up to 2.88 GB/s in sequential reads and 1.87 GB/s in sequential writes. The superior read/write performance makes them ideally suited for a broad range of application workloads, from data center applications such as email and database servers to more compute-intensive applications such as streaming video, OLTP and data archival.
The 9200 series controllers provide channel customers with a low-cost upgrade that is designed to easily integrate with existing 3Gb/s SATA and SAS infrastructure to offer dramatically improved performance and scalability.
"LSI’s strong channel partnerships are a key strategic advantage in the marketplace and central to the company’s business strategy," said Phil Bullinger, executive vice president and general manager, Engenio Storage Group, LSI. "As the world’s No. 1 provider of RAID controllers in the channel, our commitment to channel partners starts at the top, reaches throughout the company and is backed by the industry’s most complete selection of SATA and SAS RAID controllers and host bus adapters. With today’s launch, we’re providing our partners with a powerful performance advantage and focused innovations that address their customers’ evolving storage requirements in an ultra-competitive industry."
New features and flexible drive support
New 6Gb/s SAS product features include support for self-discovery/self-configuring expanders and longer cables, simplifying the deployment of larger and more complex storage topologies. The new controllers also bring standardized zoning which improves storage efficiencies by allowing multiple servers to share storage devices.
The 9200 series controllers also deliver the flexibility to support both high-performance SAS hard drives and cost-effective, high-capacity SATA drives, as well as energy-efficient SSDs. Industry-first support for self-encrypting drives (SEDs) is also provided for enhanced data security utilizing LSI SafeStore(TM) Encryption Services.
LSI SafeStore Encryption Services, together with SEDs, secure a drive’s data from unauthorized access or modification resulting from theft, loss or repurposing of drives. Local key management in the controller is designed to protect data from security breaches with minimal cost and complexity.
