American Megatrends Assigned Two Patents

Boot caching for boot acceleration within storage systems

American Megatrends Inc., Norcross, GA, has been assigned a patent (8,352,716) developed by four co-inventors for a "boot caching for boot acceleration within data storage systems."

The co-inventors are Paresh Chatterjee, Srikumar Subramanian, Suresh Grandhi, and Vijayarankan Muthirisavenugopal, Fremont, CA

The abstract of the patent published by the U.S. Patent and Trademark Office states: "Technologies are described herein for boot caching to accelerate boot access in a data storage system providing boot consolidation. Boot caching may be provided to improve boot access for multiple clients concurrently booting from a common storage server. Boot statistics may be collected per user or client. The boot statistics can determine common patterns within the boot procedures of the clients and may be used to compute boot caching tables. These tables may then be used during boot caching to accelerate booting of clients. A boot caching mechanism can be implemented to support improved booting performance by caching data blocks common to multiple booting volumes. This approach can leverage the condition that much of the data loaded by clients at boot time may be substantially identical, because booting can involve loading the same operating system components into each client."

The patent application was filed on Jan. 16, 2009 (12/355,439).
 

Page object caching
for variably sized access control lists in storage systems

American Megatrends Inc., Norcross, GA, has been assigned a patent (8,352,497) developed by Paresh Chatterjee, Fremont, CA, Srikumar Somangili Subramanian, Newark, CA, and Raghavan Sowrirajan, Fremont, CA, for a "page object caching for variably sized access control lists in data storage systems."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "Technologies are described herein for caching variably sized access control lists (ACLs) in a data storage system utilizing page object caching. A request to access a file is received. An inode number of the requested file is identified. A hash key based on the inode number and a predefined hash value is determined. A determination is made as to whether the hash key is contained in a hash list. In response to determining that the hash key is contained in the hash list, access to a page object in the memory is provided. The page object contains an access control list (ACL) associated with the requested file. The ACL is retrieved from the page object."

The patent application was filed on Feb. 9, 2010 (12/702,942).
