IBM Power9 DDR4 Memory

IBM POWER9 Memory

IBM POWER9 servers have five high performance Mbps DDR4 ECC memory size options to choose from that can significantly affect system performance, especially logical partitions that uses shared memory resources. Planning for future IBM POWER9 memory upgrades should be taken into account when deciding which memory feature size and quantity to purchase. IBM POWER9 systems with two processor sockets have 32 DDR4 memory DIMM slots, providing a maximum of 4TB of Power9 memory, and single processor socket systems can have a maximum of 2TB of IBM POWER 9 memory using 16 DDR4 memory slots. The IBM S914 9009-41A and IBM S914 9009-41G system models have a maximum of 1TB of main storage.
