The information displayed here allows you to see the utilization of the shared memory pool at the indicated date and time.
The information displayed is as follows:
Pool size (GB): The shared memory pool size in gigabytes (GB).
Memory overcommitment(GB): The difference between the aggregated logical memory of all partitions in the shared memory pool and the size of the shared memory pool (in gigabytes) at the indicated date and time. This value is a measure of the benefit of Active Memory Sharing as it indicates the amount of memory which partitions can use that is not backed by physical memory. A negative value means the memory is not overcommitted.
Memory overcommitment (percent): The memory overcommitment expressed as a percentage of the shared memory pool size. If the memory overcommitment in gigabytes has a negative value, the overcommitment percent is a value of zero.
Partition logical memory (GB): The amount of logical memory (in gigabytes) assigned to all of the partitions in the shared memory pool.
Partition I/O entitled memory (GB): The amount of I/O entitled memory (in gigabytes) assigned to all of the partitions in the shared memory pool.
Partition mapped I/O entitled memory (GB): The amount of I/O entitled memory (in gigabytes) mapped by all of the partitions in the shared memory pool.
System firmware pool memory (GB): The amount of memory (in gigabytes) in the shared memory pool that is being used by system firmware to manage the shared memory pool and all of the partitions in the shared memory pool.
Page fault rate (faults/second): The number of page faults per second.
Page-in delay (microseconds): The page-in delay, in microseconds, spent waiting for page faults since the previous sample.
Page-in delay (percent): The page-in delay, expressed as a percentage of total time.
