Fusion-IO Assigned Two Patents

1/ Increasing data integrity in redundant storage system, 2/ Power reduction management in storage device

Increase data integrity in a redundant storage system

Fusion-IO, Inc., Salt Lake City, UT, has been assigned a patent (8,281,227) developed by seven co-inventors for an "apparatus, system, and method to increase data integrity in a redundant storage system."

The co-inventors are Jonathan Thatcher, Lehi, UT, David Flynn, Sandy,
UT, Joshua Aune, South Jordan, UT, Jeremy Fillingim, Salt Lake City, UT,
Bill Inskeep, West Valley City, UT, John Strasser, Syracuse, UT, and
Kevin Vigor, Salt Lake City, UT.

The abstract of the patent published by the U.S. Patent and Trademark Office states: "An
apparatus, system, and method are disclosed to increase data integrity
in a redundant storage system. The receive module receives a read
request to read data from a logical page spanning an array of N+P number
of storage elements. The array of storage elements includes N number of
the storage elements each storing a portion of an ECC chunk and P
number of the storage elements storing parity data. The data read module
reads data from at least a portion of a physical page on each of X
number of storage elements of the N+P number of storage elements where X
equals N. The regeneration module regenerates missing data. The ECC
module determines if the read data and any regenerated missing data
includes an error. The read data combined with any regenerated missing
data includes the ECC chunk
."

The patent application was filed on May 18, 2009 (12/468,041).

Power reduction management in a storage device

Fusion-IO, Inc., Salt Lake City, UT, has been assigned a patent (8,289,801) developed by six co-inventors for an "apparatus, system, and method for power reduction management in a storage device."

The co-inventors are Lance L. Smith, San Jose, CA, Jeremy Fillingim,
Salt Lake City, UT, David Flynn, Sandy, UT, Bill Inskeep, West Valley
City, UT, John Strasser, Syracuse, UT, and Jonathan Thatcher, Liberty
Lake, UT.

The abstract of the patent published by the U.S. Patent and Trademark Office states: "An
apparatus, system, and method are disclosed for power loss management
in a nonvolatile data storage device. A monitor module initiates a power
loss mode in the nonvolatile data storage device in response to a
primary power source failing to supply electric power above a predefined
threshold to the nonvolatile data storage device. A secondary power
source supplies electric power to the nonvolatile data storage device
for at least a power hold-up time during the power loss mode. A power
loss module adjusts execution of in-process operations on the
nonvolatile data storage device during the power loss mode so that
essential in-process operations execute within the power hold-up time
."

The patent application was filed on Sept. 9, 2010 (12/878,981).
