What you should know about storage-class memory
Storage-class memory (SCM) is accessed, in chunks called increments, through extended asynchronous data mover (EADM) subchannels.
The LPAR on which your Linux® instance runs
must be configured to provide SCM.
- At least one EADM subchannel must be available to the LPAR. Because SCM supports multiple concurrent I/O requests, it is advantageous to configure multiple EADM subchannels. A typical number of EADM subchannels is 64.
- One or more SCM increments must be added to the I/O configuration of the LPAR.
In Linux, each increment is represented as a block device. You can use the block device with standard Linux tools as you would use any other block device. Commonly used tools that work with block devices include: fdisk, mkfs, and mount.
