IBM announces new Power9 processor based E950 E980 server systems
As a single server or node, the Power9 E950 supports up to four (4) CPU processor sockets each with multiple cores. An E980 system comprises up to four E950 based systems as a solution. The new E950 succeeds Power E850 and E850C, its machine type model number is 9040-MR9 that is a 4U single enclosure with two or four processor modules.
IBM Power9 E950 and E980
As a refresher, leveraging IBMs proprietary processor chip technology called Power, which are used in their various mid-range and higher end server solutions.
The Power9 E950 and E980 systems support PowerVM virtualization, along with virtual machine (VM) mobility as well as optimization for OpenStack among other workloads.
IBM touts Power9 E950 (AIX and Linux) and E980 (AIX, Linux, I systems) optimized for:
- Analytics, AI (ML/DL) and Cognitive computing
- Faster cores and threads, more performance per socket
- More bandwidth and lower latency
- Super Compute (SC), Technical, High Performance Compute (HPC)
- High bandwidth graphical processing unit (GPU) attachment
- Optimized CPU GPU memory sharing and interaction
- Bandwidth optimized main memory
- Virtual addressing optimization
- Cloud and Hyper Scale Data Infrastructures and Data Centers
- Dense performance and energy consumption
- Virtualization assist, QoS, power management and security
- Fast I/O subsystem for server I/O to storage and networks
- Enterprise data infrastructures and data centers
- Scale-up and scale-out
- Server and workload consolidation
- Up to 4TB of buffered memory per socket (16TB per E950 node)

E950 is a 4U server (or E980 node) with compute and memory features including:
- Power9 8,10,11 or 12 cores per socket, up to 48 cores (4 x 12 cores)
- Four times memory compared to E850 systems (up to 16TB or 4TB per socket)
- Eight (8) memory riser cards with 16 DDR4 DIMM each (8,16,32,64 or 128GB DIMM)
- Memory bandwidth of up to 920 GB/sec (note that is big B not Gb or little b)
- Refresh your server, CPU, compute, socket, core and threads knowledge here.
E950 also features faster I/O subsystem for server I/O to storage and networks:
- 630GB/sec (e.g. 5Tbpsec) I/O bandwidth
- NVIDIA NVLink GPU attachment, PCIe Gen4 and OpenCAPI I/O
- Up to eight (8) (4 socket systems) PCIe Gen4 x16 (16 lanes each) card slots
- Up to two (2) PCIe Gen4 x8 (8 lanes each) card slots
- Up to 144 PCIe lanes (4 socket systems), full height, half length
- USB 3 (2 front, 2 rear)
- 12 internal 2.5” form factor storage bays for HDD and SSDs including up to eight (8) SAS SAS, and four NVMe U.2 (8639). Note that NVMe devices attach via PCIe ports and lanes.
- Hot plug components and optional I/O expansion as well as storage drawers
- Here is a refresher (or primer) on PCIe, as well as NVMe, SAS, and SSD technologies.

What this all means
These new systems provide increase in not only compute, also memory as well as server I/O for storage and networking. With the addition of multiple PCIe Gen4 x16 card slots, more GPUs such as those from NVIDIA as well as fast Fibre Channel, SAS and NVMe based storage can be attached to these systems.
With a good number of x16 PCIe Gen4 slots, the E950 and E980 systems are capable of supporting more GPU offload cards such as those from NVIDIA, along with other ASIC or FPGA accelerator devices. In addition to compute offload, the x16 PCIe Gen4 slots enable server I/O cards to more storage devices including faster Fibre Channel, Ethernet, SAS as well as NVMe attachment.
Overall, IBM announces new Power9 processor based E950 E980 server systems is a good move for existing customers of AIX, Linux as well as with the E980 for i systems.
Ok, nuff said, for now.
