LSI Assigned Three Patents

Startup reconstruction of logical-to-physical address
translation data for solid state disks

LSI Corp., Milpitas, CA, has been assigned a patent (8,301,861) developed by four co-inventors
for a "startup reconstruction of logical-to-physical address translation data
for solid state disks."

The co-inventors are Randy Reiter, Rochester, MN, Timothy
Swatosh, Rochester, MN, Pamela Hempstead, Oronoco, MN, and Michael Hicken, Rochester,
MN.

The abstract of the patent published by the U.S. Patent
and Trademark Office states: "Described embodiments provide reconstruction
of logical-to-physical address mapping data for one or more sectors of a storage
device at startup of a media controller. The sectors of the storage device are organized
into blocks and superblocks and the address mapping data is stored in a volatile
memory. At a startup condition of the media controller, a buffer layer module of
the media controller allocates space in the volatile memory for one or more logical-to-physical
address mapping data structures. A media layer module of the media controller determines
a block type of each block of the storage device and places each block of the storage
device into corresponding groups based on the determined block type of each block.
The one or more blocks of each group are processed, and one or more address mapping
data structures for the storage device are constructed in the allocated space in
the volatile memory."

The patent application was filed on April 29, 2010 (12/769,910).

System eliminating hardware duplication during application testing of
an internal storage array across different OSs

LSI Corp., Milpitas, CA, has been assigned a patent (8,296,782) developed by four co-inventors
for a "system eliminating hardware duplication during application testing of
an internal storage array across different OSs."

The co-inventors are Mahmoud
K. Jibbe, Wichita, KS, Preeti Badampudi, Soham Kar, and Shivprasad Prajapati, Bangalore,
India.

The abstract of the patent published by the U.S. Patent
and Trademark Office states: "A method for capturing data comprising the steps
of (A) handling a call for a first OS at a storage library, (B) routing the call
from the storage library to a controller firmware, (C) sending a response to the
call from the controller firmware to the storage library, and (D) storing the response
in a data store box for later use by the storage library."

The patent application was filed on Sept. 26, 2008 (12/238,858).

Storage system management tool including simulation
mode to support pre-configuration of storage systems

LSI Corp., Milpitas, CA, has been assigned a patent (8,280,715)
developed by Martin Jess, Erie, CO, for "storage system management tool including
simulation mode to support pre-configuration of storage systems."

The abstract of the patent published by the U.S. Patent
and Trademark Office states: "A method may include receiving a first selection
via a user interface comprising a hardware configuration for a simulated computer
storage system, the hardware configuration including a plurality of hardware components.
The method may also include receiving a second selection via the user interface
comprising a storage configuration for the plurality of hardware components of the
simulated computer storage system. Further, the method may include creating a storage
configuration template utilizing the storage configuration. Additionally, the method
may include associating the plurality of hardware components of the simulated computer
storage system with the storage configuration template. Further, the method may
include storing the plurality of hardware components of the simulated computer storage
system and the associated storage configuration template."

The patent application was filed
on June 5, 2009 (12/455,747).
