| 发明名称 | Firmware management of storage class memory for connected or disconnected I/O adapters | ||
| 摘要 | A computer program product is provided and includes a tangible storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for detecting connections of two or more input/output (I/O) adapters, each of the two or more I/O adapters having one or more solid state devices (SSDs) connected thereto, and presenting a storage class memory address space for all of the connected SSDs that is independent of connections and disconnections between each of the one or more SSDs and each of the two or more I/O adapters and the processing unit. | ||

| 主权项 | 1. A computer program product comprising a non-transitory computer readable medium, which is readable by a processing circuit, and on which instructions are stored for execution by the processing circuit for: detecting connections of two or more input/output (I/O) adapters, each of the two or more I/O adapters having one or more solid state devices (SSDs) connected thereto; and presenting a storage class memory address space for all of the connected SSDs that is independent of connections and disconnections between each of the two or more I/O adapters by: grouping into arrays SSDs connected to a first I/O adapter and SSDs connected to a second I/O adapter, which is physically connected to the first I/O adapter, the arrays including volume sets spanning the first and second I/O adapter and being accessible via either of the first and second I/O adapter with the SSDs connected to the second I/O adapter respectively mirroring the SSDs connected to the first I/O adapter; and grouping into arrays the SSDs connected to a third I/O adapter and SSDs connected to a fourth I/O adapter, which is physically disconnected from the third I/O adapter, the arrays including volume sets spanning the third and fourth I/O adapters and being accessible via firmware with the SSDs connected to the fourth I/O adapter respectively mirroring the SSDs connected to the third I/O adapter. | ||
