Key features of the IBM Power System S922

Powerful 1- or 2-socket server with up to 22 active cores

A 1- or 2-socket server with up to 22 activated cores and I/O configuration flexibility. It features a fully activated IBM® POWER9™ processor module configuration in a 19-inch rack-mount, 2U (EIA units) drawer configuration with 1-core or 11-core 3.8 GHz, 10-core or 20-core 2.5 GHz, or 8-core or 16-core 3.0 GHz, or 4-core 2.3 GHz. Up to 4096 GB of DDR4 memory running at different speeds of 2133, 2400 and 2666 Mbps.

Optional and integrated features

Optional PCIe Gen4 drive with two U.2 module slots are available with S922 as well as expansion capabilities for the EXP12SX/EXP24SX SFF Gen2 bay Drawer and Hot-plug PCIe Gen4 slots. Integrated capabilities include: Service processor; EnergyScale technology; Hot-plug and redundant cooling; USB 3.0 ports; Two HMC ports; One system port with RJ45 connector and two hot-plug, redundant power supplies.

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.

As easy as a QR scan

Speeds development and management of mobile applications. It includes a development environment, runtime middleware, a private enterprise application store and a management and analytics console to: Co-locate applications on a scalable server; streamline access to data and applications with virtual networking; accelerate deployment; and reduce overhead by using existing production and disaster recovery infrastructure.

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. Supports up to 4 TB of memory.

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.

Cache availability

The L2 and L3 caches in the POWER9 processor and L4 cache 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.

Live Partition Mobility

With Live Partition Mobility, users can migrate an AIX, Linux, or IBM i 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.

Service processor

The service processor provides the capability to diagnose, check the status 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.
