The new Power System E950 server is ideal for cloud deployments with built-in virtualization, flexible capacity, and utilization. Due to the new POWER9 architecture, the E950 provides improvements in application delivery and IT services through increased throughput, reduced response times, and increased memory and I/O bandwidth.
The new Power System E980 (image) server delivers scalability, performance, and availability for data centers with the most demanding UNIX, IBM i, and Linux applications. It gives you high throughput, performance, and scalability in a new modular high-end system with up to 192 POWER9 cores, up to 64 TB memory, and the fastest POWER9 processors in the Power Systems portfolio. .
Start a conversation with your clients or IT decision makers with one of the following 5 things to know:
1. Massive throughput, performance, and scalability
A component that is crucial to system operations is the system reference clock source which is responsible for providing a synchronized clock signal to all functional units. Each system node of a Power E980 server utilizes its own private set of two redundant system clock/control cards. If there is a failure in any of the clock/control cards, the second card ensures continued operation of the system until a replacement is scheduled. Unlike the POWER8 processor-based enterprise class servers Power E870, Power E870C, Power E880, and Power E880C the Power E980 system no longer requires a global reference clock source in the system control. Cable for clocking between SCU and CEC no longer required. This frees the architects to unlock even more performance.
POWER9 processor-based scale-up systems will have the maximum performance mode (MPM) enabled by default. In response to varying workload characteristics. This mode dynamically adjusts processor frequency to maximize performance and enable a much higher processor frequency range in comparison to POWER8 servers
2. NVMe local boot support
The servers support under-the-covers NVMe devices which can be individually assigned to independent partitions. To use storage that is locally attached (DASD devices or SSDs) through SAS adapters offers an other option to provide boot devices to critical operating systems such as VIOS partitions.
3. Significant RAS enhancements for the E950
The following highlights the most important RAS improvements for the Power E950 system in relation to the Power E850 and Power E850C predecessor systems:
The developers are speaking freely about what is just around the corner. For those with existing EXP24S I/O drawers it is expected that after the initial GA this drawer will be supported. You won't be able to order it with the system, but if you have them, the plan is to support them. The initial E980 offering will be a two-node system supporting two I/O drawers per node. After the initial availability four system nodes and four I/O drawers per node are coming. Talk to your IBM representative for more information about support (which may change at any time!).
5. The only native PCIe Gen4 on-chip controllers on the market
Future proofing the I/O subsystem by being the first-to-market to include PCIe Gen4 controllers for true adap
