Abstract
A NVM switch has been designed that allows multiple hosts to simultaneously and independently access a single port NVM device. While this active-active multi-host usage configuration allows for a variety of uses of lower cost single port NVM device, an issue with one of the hosts can delay or block transactions between the other host and the NVM device. The NVM switch includes logic that isolates activity of the multiple hosts despite logic of the switch being shared across the hosts. When the switch detects an issue with one host ('error host'), the switch clears the in-flight commands of the error host and flushes data of the error host. Likewise, the NVM switch ensure proper communication of error reporting from attached NVM devices to the multiple hosts.
