Abstract:
1. A method, comprising: 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, wherein the presenting of the storage class memory comprises: 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.
