Lightweight host multihoming
Described herein are systems and methods for host multihoming with no state synchronization between top-of-rack (ToR) switches coupled to multiple hosts. ToR switches of a multi-homing system share a virtual MAC address and respond to Address Resolution Protocol (ARP) requests and/or Neighbor Discovery (ND) solicitations for a default gateway IP address from the host with the virtual MAC address. Ports on a ToR switch may be configured either with a static ARP and/or ND entry, or be configured to learn via a discovery protocol. The lightweight host multihoming system may have modified flooding behavior, ARP/ND handling, and data path forwarding. ARP/ND traffic from a host is processed by a ToR switch, while other multicast traffic may be discarded. Embodiments of the host multihoming system provide a lightweight solution for software implementation with minimal changes imposed on the host or network design. |

Custom color unique identifier override workflow
A system and method are provided which enable overriding a custom color callout in a print job. Provision is made for a user to associate a unique ID with a custom color callout in a print job, e.g., during generation of the print job or at the printer. The custom color callout provides for a part of the print job to be rendered with a specific custom colorant, e.g., by identifying the name of the custom colorant. The unique ID is associated, in memory, with a custom colorant station of a print engine, independent of any custom colorant that may be housed in the custom colorant station. The method further includes identifying the custom colorant station of the print engine associated with the unique ID and sending the print job in a format for printing to the print engine for printing the part of the print job with a first custom colorant housed in the identified custom colorant station. |

Solid-state drive with initiator mode
A solid-state drive configured to store persistent digitally encoded data may operate in an initiator mode. When operating in the initiator mode, the solid-state drive may initiate the generation and issuance of a command or a request for another solid-state drive to carry out a data storage related procedure. The command or request generated by the solid-state drive may be communicated directly to another solid-state drive without the communications passing through an intermediate device, such as a host processor. |

Apparatus for processing received data
To speed up decoding of a range code. A decompression circuit calculates a plurality of candidate bit values for each bit of the N-bit string based on a plurality of possible bit histories of a bit before a K-th bit in parallel for a plurality of bits, and repeatedly selects a correct bit value of the K-th bit from the plurality of candidate bit values based on a correct bit history of the bit before the K-th bit to decode the N-bit string. |

Memory system and operating method thereof
Embodiments of the present disclosure relate to a memory system and an operating method thereof. According to the embodiments of the present disclosure, the memory system may include a plurality of cores, a control core, and a shared memory. When processing the event, the control core may select a first core executing a target job requiring distributed execution among the plurality of cores, and the first core may run a first firmware among the plurality of firmwares to execute the target job. The control core may select a second core to execute the target job together with the first core, and may control the second core to run the first firmware. The control core may control the first core and the second core to perform distributed execution of the target job. |

Implementing variable number of bits per cell on storage devices
Systems and methods are disclosed including a memory component and a processing device, coupled to the memory component. The processing device can program a block of the memory component using a first type of memory cells storing a first number of bits per memory cell. The processing device can then determine that an amount of memory used of the memory component is greater than a capacity threshold. Responsive to determining that a frequency of access to the block meets a criterion, the processing device can then program the block using a second type memory cells storing a second number of bits per memory cell, wherein the second number of bits exceeds the first number of bits. |

VM protection with true zero RTO
One example method includes powering off a replica VM, taking a snapshot of an OS disk of a source VM associated with the replica VM, taking a snapshot of an OS disk of the replica VM, generating a list of blocks that includes all blocks of the source VM OS disk that have changed since a preceding cloning or snapshot process and further includes all blocks of the replica VM OS disk that have changed since the preceding cloning or snapshot process, and performing an override of the replica VM disk by writing, to the replica VM OS disk, the respective source VM OS disk values for each block in the list of blocks. |
