Key Features of the IBM Power System S914

Powerful 1-socket server with up to eight active cores

A 1-socket server with up to eight activated cores and I/O configuration flexibility. It features a fully activated IBM® POWER9™ processor module configuration in a 19-inch rack-mount, 4U (EIA units) form factor with 4-core, 6-core, and 8-core up to 3.8 GHz. Up to 1024 GB of DDR4 memory running at speeds of 2133, 2400 and 2666 Mbps.

Memory subsystem RAS

Memory has error detection and correction circuitry so that the failure of any one specific memory module within an ECC can be corrected absent of any other fault. A spare DRAM per rank on each memory port provides for dynamic DRAM device replacement during runtime operation. Dynamic lane sparing on the DMI link allows for repair of a faulty data lane.

Full PCIe Gen4 architecture

Provides a base 18 SFF-3 Bays/Dual IOA with Write Cache and 12 SFF-3 Bays/RDX Bays; split feature to 6+6 SFF Bays with ability to add a second SAS Controller; and 12 SFF-3 Bays/RDX Bay/2 EXT PT.

Processor availability functions

The POWER9 processor performs processor instruction retry for some transient errors and alternate processor recovery for a number of core-related faults. This significantly reduces exposure to both hard (logic) and soft (transient) errors in the processor core.

Optional and integrated features

Optional PCIe Gen4 drive with two U.2 module slots as well as expansion capabilities for the EXP24SX SFF Gen2 bay Drawer and hot-swap PCIe Gen4 slots. Integrated capabilities include: service processor; EnergyScale technology; hot-swap and redundant cooling; USB 3.0 ports; two HMC ports; and one system port with RJ45 connector.

Cache availability

The L2 and L3 caches in the POWER9 processor in the memory buffer chip are protected with double-bit detect, single-bit correct error detection code (ECC). In addition, a threshold of correctable errors detected on cache lines can result in the data in the cache lines being purged and the cache lines removed from further operation without requiring a reboot in the PowerVM environment.

PowerVM hypervisor built-in at no additional cost

PowerVM is a cloud-optimized hypervisor that comes built-in to every POWER9 server at no additional cost. PowerVM reduces overhead costs through workload consolidation and capacity planning capabilities.

Live Partition Mobility

With Live Partition Mobility, users can migrate a partition running on one POWER system to another POWER system without disrupting services. The migration transfers the entire system environment, including processor state, memory, attached virtual devices, and connected users. It provides continuous operating system and application availability during planned partition outages for repair of hardware and firmware faults.

As easy as a QR scan

Get access to important customer service functions by scanning QR labels placed on the system to provide access to key service functions through a mobile device. When the QR label is scanned, it will go to a landing page specific to that server which contains many of the service functions of interest while physically located at the server. These include things such as installation and repair instructions, service diagrams, and reference code look up.

Service processor

The service processor provides the capability to diagnose, check the status of, and sense the operational conditions of a system. It runs on its own power boundary and does not require resources from a system processor to be operational to perform its tasks.
