Expand System Memory Capacity
Overview
This function expands the upper limit of the system memory capacity used in the storage system.
This function is supported in the ETERNUS DX8100 S4/DX8900 S4.
Use this function to register a license (*1) when adding system memory. The added system memory cannot be used until a license is registered.
If multiple "memory expansion licenses" are required to expand to the intended capacity, all the licenses must be registered.
To expand the cache capacity, register "memory expansion license" and then specify "Case of cache memory capacity expansion without memory expansion." to expand the memory in hot mode. Refer to the [Add Memory] function for details.
*1 : In this manual, "memory expansion license" represents a license for expanding the upper limit of the system memory. A "memory expansion license" is issued for each storage system.
Multiple "memory expansion licenses" can be registered in a single operation.
