Patent number: 8819335Abstract: A system and method of providing enhanced data processing and analysis in an infrastructure for distributed computing and large-scale data processing. This infrastructure uses the Hadoop™ framework to divide an application into a large number of small fragments of work, each of which may be performed on one of a large number of compute nodes. The work may involve map tasks and reduce tasks which may be used to categorize and analyze large amounts of data in distributed systems. This infrastructure includes a cluster with a master node and a plurality of slave nodes. The slave nodes may include, or may be, intelligent solid-state drives capable of executing Map-Reduce functions. The use of intelligent solid-state drives reduces the need to exchange data with a CPU in a server.Type: GrantFiled: August 30, 2013Date of Patent: August 26, 2014Assignee: NXGN Data, Inc.Inventors: Nader Salessi, Joao Alcantara

Patent number: 8464073Abstract: A secure storage device includes a storage medium configured to securely store data received from a host. The storage device further includes a host interface configured to transfer data between the host and the storage device and an encryption engine. The encryption engine is configured to encrypt data received from a host using a key and provide the encrypted data to the storage medium for storage. The encryption engine is further configured to decrypt encrypted data received from the storage medium and provide the data to the host via the host interface. In response to a predetermined condition, the storage device is configured to disable the encryption engine thereby preventing the encrypted data stored thereon from being decrypted.Type: GrantFiled: September 13, 2006Date of Patent: June 11, 2013Assignee: Stec, Inc.Inventor: Nader Salessi

Patent number: 8230690Abstract: A modular solid-state lamp has a plurality of replaceable and rearrangeable modules. The modular lamp uses active cooling and passive cooling for thermal management. One cooling system for the modular lamp includes at least one active cooling device and a graphite heat sink in thermal contact with the at least one active cooling device to further enhance the efficiency of the cooling system. The modular solid-state lamp includes at least two modules, a power supply module and a light source module. The power supply module includes a power supply and LED driver that are able to power one or more light source modules. The power supply module further includes sensors that further improve the energy-efficiency of the lamp.Type: GrantFiled: November 27, 2009Date of Patent: July 31, 2012Inventor: Nader Salessi

Patent number: 8159152Abstract: A high-power light-emitting diode (LED) lamp has a plurality of units. Each unit includes an LED die and a thermo-electric cooling device coupled to the LED die. A power source supplies a fixed current to the thermo-electric cooling device wherein the fixed current is based on heat generated by the LED die in normal operation. Accordingly, the unit operates without a controller.Type: GrantFiled: May 19, 2009Date of Patent: April 17, 2012Inventor: Nader Salessi

Patent number: 8000153Abstract: A flash storage device includes flash storage units that are erased in response to a condition or command while allowing the flash storage device to be used subsequent to the erase. A flash controller interface receives a command for erasing the flash storage device and provides an erase command to flash controllers in the flash storage device. Alternatively, the flash storage device detects a condition in response to which the flash controller interface provides an erase command to the flash controllers. Each flash controller independently erases a flash storage unit in response to receiving the purge command such that the flash storage units are erased substantially in parallel with each other and the erase operations overlap. Subsequent to the erase, certain control data is reconstructed to allow subsequent use of the flash storage device.Type: GrantFiled: October 1, 2008Date of Patent: August 16, 2011Assignee: STEC, Inc.Inventors: Nader Salessi, Hooshmand Torabi, Chak-Fai Cheng, Hosein Gazeri, Richard Mataya

Patent number: 7958280Abstract: A process of data storage utilizing a data management system that transfers data between a host system and multiple storage devices through multiple channels. The data management system receives data from the host system and writes the data as data segments to the multiple storage devices. Each data segment may comprise one sector, more than one sector, or a portion of a sector, depending on the embodiment. The data segments are transferred to and from the multiple storage devices in parallel fashion while the data in each data segment is transferred to its corresponding data storage device sequentially. The data management system reassembles data segments received from the data storage devices and sends the data to the host system.Type: GrantFiled: October 26, 2007Date of Patent: June 7, 2011Assignee: STEC, Inc.Inventors: Nader Salessi, Hooshmand Torabi

Patent number: 7929354Abstract: A flash storage device includes flash storage units that are purged in response to a condition or command wherein, during or subsequent to the purge, the purge is verified. A flash controller interface receives a command for purging the flash storage device and provides a purge command to flash controllers in the flash storage device. Alternatively, the flash storage device detects a condition in response to which the flash controller interface provides a purge command to the flash controllers. Each flash controller independently erases a flash storage unit in response to receiving the purge command such that the flash storage units are erased substantially in parallel with each other. The purge of the flash storage device is subsequently verified.Type: GrantFiled: April 11, 2009Date of Patent: April 19, 2011Assignee: STEC, Inc.Inventors: Nader Salessi, Hooshmand Torabi, Chak-Fai Cheng, Hosein Gazeri, Richard Mataya

A flash controller interface receives a command for purging the flash storage device and provides a purge command to flash controllers in the flash storage device. Alternatively, the flash storage device detects a condition in response to which the flash controller interface provides a purge command to the flash controllers. Each flash controller independently erases a flash storage unit in response to receiving the purge command, by writing a pattern of data to the flash storage unit, such that the flash storage units are purged substantially in parallel with each other.Type: GrantFiled: April 11, 2009Date of Patent: March 8, 2011Assignee: STEC, Inc.Inventors: Nader Salessi, Hooshmand Torabi, Chak-Fai Cheng, Hosein Gazeri, Richard Mataya

Patent number: 7894288Abstract: A parallel data storage system for storing data received from, or retrieving data to, a host system using multiple data storage devices. The system includes an interface for communicating with the host system and a buffer configured to store data sectors received from the host system via the interface. A switch is used to selectively connect the interface and the data storage devices to the buffer to facilitate the transfer of data into and out of the buffer. The data sectors are transferred by segmenting each sector into multiple smaller data cells and distributing these data cells among the data storage devices using an arbitrated distribution method.Type: GrantFiled: October 6, 2009Date of Patent: February 22, 2011Assignee: STEC, Inc.Inventors: Hooshmand Torabi, Chak-Fai Cheng, Nader Salessi, Hosein Gazeri
