Software aids SAS adapter SSD management, data protection.March 25, 2009 -
MegaRAIDŽ v3.6 endows 3 Gbps MegaRAID SAS 87XX and 88XX series adapters with features such as management and data protection capabilities for solid state drives (SSD), hard drive spin-down for reduced power consumption, and VMwareŽ virtualization support. By leveraging revertible hot spare and predictive failure event notifications to automatically initiate rebuild to spare, data is preserved on SSD whose health or performance falls below par.

LSI MegaRAID Release 3.6 Advances Solid State Drive Management and Data Protection for SAS/SATA Adapters
New features also enable hard drive spin-down for reduced power consumption and energy costs; extend VMware virtualization support
MILPITAS, Calif., March 10 -- LSI Corporation (NYSE:LSI) today announced MegaRAID(R) Release 3.6, which provides new features and advanced functionality for 3Gb/s MegaRAID SAS 87XX and 88XX series adapters. New features include enhanced management and data protection capabilities for solid state drives (SSD), hard drive spin-down for reduced power consumption and expanded VMware(R) virtualization support.
"Because of their speed, reliability and decreasing cost, solid state drives are beginning to be deployed for mainstream applications," said Roger Cox, Research Vice President, Gartner. "As SSD adoption expands, leading-edge storage management devices will allow users to realize the benefits of SSD without compromising storage configurability, manageability or availability."
SSDs can read randomly stored data up to 100 times faster than rotating media, thus are ideally suited for OLTP, database queries, high-bandwidth networks and operating environments requiring frequent page swaps. MegaRAID Release 3.6 offers full support for SSD technology by providing a comprehensive set of management tools within the MegaRAID Storage Manager (MSM). Users now have the ability to control and manage solid state drives just as is possible with hard disk drives (HDDs) and prevent improper utilization such as mixing SSDs and rotating HDDs. MSM limits maintenance I/Os to the SSD which can improve performance and extend useable life.
MegaRAID Release 3.6 also offers a new feature called SSD Guard(TM), which increases the reliability of system configurations using SSDs and provides added data protection for users employing RAID 0 configurations. By leveraging revertible hot spare and predictive failure event notifications to automatically initiate a rebuild to a spare, data is preserved on an SSD whose health or performance falls below par.
Lower power, extended virtualization support and Tylersburg ready
The new MegaRAID Dimmer Switch(TM) feature provides green benefits to data centers by reducing the power consumption of devices attached to MegaRAID adapters. With MegaRAID Release 3.6, any unconfigured drive connected to a MegaRAID adapter will be spun down after thirty minutes of inactivity. This eliminates inefficiencies created by the continuous supply of power to every drive regardless of usage.
"As SAS continues to drive the resurgence of the direct-attached storage market, customers expect host-based RAID solutions to support advanced technologies such as SSD, hard drive spin-down and virtualization," said Kelly Bryant, DAS RAID business line director, Engenio(R) Storage Group, LSI. "These advanced, cost-saving features are available to customers today on our 3Gb/s SAS MegaRAID adapters, and will be available later this year on our 6Gb/s SAS offerings."
MegaRAID Release 3.6 also extends virtualization support for VMware hypervisor technology to include the recently announced ESXi version. With full validation and support for ESX and ESXi, OEMs and system builders can now use MegaRAID Storelib-based management tools without the need to rewrite applications to run in the small footprint ESXi environment. Additionally, Release 3.6 adds Unified Extensible Firmware Interface (UEFI) 2.0 support for the new Intel Tylersburg chipset. The MegaRAID UEFI driver enables system builders to define a clean interface between operating systems and the platform at boot time, and supports an architecture-independent mechanism for initializing add-in cards.
More information on these and other new MegaRAID Release 3.6 features, such as additional operating system and SAS tape drive support, is available at the LSI Channel Gateway (lsichannelgateway.com) or lsi.com/megaraid.
