LSI Corp. has announced that LSI SandForce SF-2200 controllers for solid-state drives now enable SSD manufacturers to build drives compliant with the Trusted Computing Group (TCG) Opal specification. In addition to advanced self-encryption technology, LSI also reduced power consumption of its SF-2200 controllers with DevSleep technology.


“Businesses around the world have strong incentives to protect sensitive data by converting notebook PCs to encrypted drives. Meanwhile a growing number of IT managers are adopting SSDs either to raise employee productivity or to extend the life of corporate laptops. By introducing Opal compliant SandForce SSD controllers, LSI is addressing both of these needs at once," said Jim Handy, SSD analyst for Objective Analysis.

Many companies are moving to SSDs in laptops to launch applications faster, reduce boot times and extend battery life. However, concerns over cost-effective data security and the complexity of deploying and managing self-encrypting drives (SEDs) are slowing even wider adoption.

LSI SandForce SSD controllers automatically encrypt data-at-rest on SSDs used in laptops and other corporate mobile computing platforms with the 256-bit advanced encryption standard (AES-256). Together with TCG Opal compliance, LSI SandForce FSPs simplify the deployment and management of hardware-based, self-encrypting SSDs in corporate environments while helping to make government-grade data security accessible to businesses of all sizes. The hardware-based encryption reduces costs and improves performance of storage sub-system.

LSI will demonstrate Opal compliant SandForce Driven member SSDs at Computex 2013. Product demonstrations will also showcase DevSleep technology, a new power-savings feature for SF-2200 client SSD controllers that enables up to a 400x reduction in SSD power consumption at idle, helping to extend battery life in ultrabook systems using the new Intel Core i-series 4000-family “Haswell” platform.

DevSleep technology is critical to meeting the standby battery life duration requirement of the Microsoft Windows 8 Connected Standby feature. Systems that support Connected Standby must drain less than 5 percent of system battery capacity over a 16-hour idle period. The feature helps to achieve the lower power targets of mobile computing devices by allowing background tasks like content updates to be performed while in standby, similar to a smartphone.

TCG Opal compliance for LSI SandForce controllers is available to SSD manufacturers via a free firmware update. DevSleep low-power state technology is currently in production and is available on volume SandForce SF-2200 controllers.
