Disclosed embodiments relate to automatically providing updates to at least one vehicle. Operations may include receiving, at a server remote from the at least one vehicle, Electronic Control Unit (ECU) activity data from the at least one vehicle, the ECU activity data corresponding to actual operation of the ECU in the at least one vehicle; determining, at the server and based on the ECU activity data, a software vulnerability affecting the at least one vehicle, the software vulnerability being determined based on a deviation between the received ECU activity data and expected ECU activity data; identifying, at the server, an ECU software update based on the determined software vulnerability; and sending, from the server, a delta file configured to update software on the ECU with a software update corresponding to the identified ECU software update.

There is provided a technique of time delivery in a computing system comprising a system call interface (SCI) located in a kernel space and operatively connected to a time client located in a user space. The technique comprises: using a time agent component located in the user space to measure data indicative of delay in a system time delivery and to derive therefrom a system time delivery error TE.sub.S2C; using TE.sub.S2C to enable correction of system time; and sending by the SCI the corrected system time in response to a “Read Clock RT” (RCRT) call received from the time client. The method can further comprise: measuring data indicative of delays in the system time delivery for RCRT calls with different priorities; and in response to a system time request received from the time client, providing the time client with system time corrected per TE.sub.S2C corresponding to the recognized priority thereof.

The present embodiments provide a stacked memory apparatus and a repairing method thereof which store information about a spare resource in a pre-bond process, check a spare resource available in a post-bond process, correct an error through an error correction code, and variably use the same number of spare resources to additionally ensure a number of spare resources in the post-bond process, thereby improving a yield.

Disclosed embodiments relate to performing updates to Electronic Control Unit (ECU) software while an ECU of a vehicle is operating. Operations may include receiving, at the vehicle while the ECU of the vehicle is operating, a software update file for the ECU software; writing, while the ECU is operating, the software update file into a first memory location in a memory of the ECU while simultaneously executing a code segment of existing code in a second memory location in the memory of the ECU; and updating a plurality of memory addresses associated with the memory of the ECU based on the software update file and without interrupting the execution of the code segment currently being executed in the second memory location in the memory of the ECU.

Sync-mark (SM) detection recovery techniques for HDDs tend to be slow and cumbersome. Typical approaches often require an entire read command to be aborted and multiple subsequent read commands with significant firmware intervention. Should a data sector be unreadable, an example recovery technique for HDDs is recursive read averaging (RRA). Using RRA, samples for failed sector reads are stored in memory. When a sector is subsequently read, the samples are averaged and replace the prior sample stored in memory. The averaged samples are then used to decode the sector. Should SMs associated with data fragments making up a sector be unreadable, the data fragments are unreadable, rendering the sector unreadable. The systems and methods described herein are used to recover previously unreadable SMs. When updated data fragments are subsequently recombined, the confidence level in the overall sector is improved, which increases the likelihood of a successful decode of the sector.

Techniques are disclosed for providing backup protection. A first subnet is established for replication in a first cluster that includes a plurality of host devices. Each of the host devices includes a respective controller virtual machine, which together form a virtual local area network for replication. Each of the controller virtual machines is assigned an Ethernet interface. A replication Internet Protocol address is assigned to each of the Ethernet interfaces of the controller virtual machines. Route tables and firewall rules of the controller virtual machines are modified to allow communications between nodes of the first subnet. The first subnet is configured with information related to a second subnet for replication in a second cluster. A dedicated communication channel is generated for replication between the first cluster and the second cluster based on the configuring.

A redundant array of independent disks (RAID) management method includes, when detecting that a component in a storage medium fails, recovering, based on a RAID policy, data stored in the failed component, saving the recovered data into a pre-defined redundant space of the RAID, and mapping an address of the failed component with the address of the redundant space, converting, according to the mapping, an address of to-be-accessed data comprised in an accessing request into an address within the redundant space, and accessing the to-be-accessed data from the redundant space according to the address within the redundant space.

A safety communication scheme for a safety-critical system which includes two or more higher level units that have voting capabilities and one or two sets of lower level units that do not have voting capabilities, involves using one channel between the high and low level units for safety and two channels for redundancy.

Memory controllers, devices, modules, systems and associated methods are disclosed. In one embodiment, an integrated circuit (IC) memory component is disclosed that includes a memory core, a primary interface, and a secondary interface. The primary interface includes data input/output (I/O) circuitry and control/address (C/A) input circuitry, and accesses the memory core during a normal mode of operation. The secondary interface accesses the memory core during a fault mode of operation.

Methods and apparatus for asynchronous replication of data in a storage network. In an embodiment, a method begins by a processing module(s) of a computing device identifying at least a first storage set and a second storage set for replicated storage of data. The processing module maintains a synchronization schedule for the first storage set and the second storage set. After initiating storage of a data object in the first storage set, the processing module determines, based at least in part on the synchronization schedule, to synchronize the first storage set and the second storage set. In response to determining to synchronize the first and second storage sets, the processing module determines that the second storage set requires the data object to maintain synchronization with the first storage set, and facilitates storage of the data object in the second storage set. The processing module may further maintain a synchronization log that tracks the status of write operations to the first storage set and the second storage set.
