An eFuse circuit may include a wordline, a first eFuse, a first logic gate, a first blowFET, and a first bitline discharge device. The first eFuse may have a first end coupled to the wordline and a second end. The first eFuse may have a first resistance when unblown and a second resistance when blown. The first logic gate may be coupled to the first end of the first eFuse. The first logic gate may be capable of driving enough current to blow the first eFuse. The first blowFET may have a source coupled to a first supply voltage, a gate coupled to a program signal, and a drain coupled to the second end of the first eFuse. The first bitline discharge device may have a gate coupled to the second end of the first eFuse, a source coupled to the first supply voltage, and a drain coupled to a first bitline.

State sensing system for eFuse memory

A method, apparatus, and computer program product for handling a failure condition in a storage controller is disclosed. In certain embodiments, a method may include initially detecting a failure condition in a storage controller. The failure condition may be associated with a specific host and a specific storage device connected to the storage controller. The method may further include determining a failure ID associated with the failure condition. Using the failure ID, en entry may be located in a data collection and recovery table. This entry may indicate one or more data collection and/or recovery processes to execute in response to the failure condition. The method may then execute the data collection and/or recovery processes indicated in the entry. While executing the data collection and/or recovery processes, connectivity may be maintained between hosts and storage devices not associated with the failure condition.

Failure-specific data collection and recovery for enterprise storage controllers

A method of automatic recovery from a boot device failure and an initial program load (IPL) failure of an operating system (OS) comprises: receiving and complying with a user selected option of an action upon an event of a boot device failure and an IPL failure. The user selected option may consist of taking the action of attempting an auto reboot of the server with the selected boot device and continuing the reboot attempts using the reduced priority boot devices from the bootlist until detection of a boot success, or taking no action allowing for manual user intervention.
