Why Upgrading to POWER9
Makes Technical Sense

*

The feeds, speeds and other specs of the E950 and E980 servers
By Sol Lederman

W

*

ith the recent launch of the
high-end Power Systems*
E950 and E980 servers,
IBM has completed its rollout of the
POWER9* processor-based servers.
Clients running older generations
of Power Systems servers may be
contemplating upgrading their IT
infrastructures by introducing new
generation servers into the mix.
The first factor many organizations consider when they're
thinking about upgrading are
server specs. How fast are the new
processors? How many processor sockets are there? How much
memory can I pack into a server?
How fast is the I/O?
For some clients, improvements
in capacity and performance aren't
compelling drivers to upgrade. For
these clients, reasons to upgrade
might include ease of creating
private clouds, the ability to perform
more granular and more scalable
virtualization, having an upgrade
path that includes a 10-year roadmap, improvements in reliability,
availability and serviceability (RAS),
and better security. Financial incentives, including pay-as-you-go
capacity on demand and the IBM
Power to Cloud Rewards Program,
may also be considerations.

the bandwidth of PCI Gen3 introduced in POWER8), and high-bandwidth (25 Gbps) links for improved
SMP throughput between nodes.
The POWER9 processor is a 14nn
Silicon-on-Insulator single-chip
module with 8, 10, 11 or 12 cores
per socket, dynamic frequency of
up to 4 GHz to speed up processing, up to 8 threads per core, dual
memory controllers and 230 Gbps
memory bandwidth.
The most powerful of the new line,
the Power Systems E980, offers up to
192 cores, up to 128 DDR4 CDIMMs,
up to 64 TB memory, up to 32 PCIe
Gen4 slots and the choice of running
IBM i, AIX* or Linux*. Compared to
the Power Systems E870C/E880C,
the E980 delivers faster processor
response time, a flatter system SMP
topology to increase system throughput, twice the memory capacity, I/O
infrastructure designed for PCIe
Gen4 that potentially doubles I/O
bandwidth with concurrent maintenance to improve throughput
and help maintain service levels,
improvements in system RAS, and
a new distributed clock design that
eliminates discrete clock cabling
from each system drawer to the System Control Unit.

Feeds and Speeds

The scale-up E950 and E980 servers
deliver a cloud-everywhere solution
optimized for private, public, hybrid
and multiclouds. The solution includes several key features:
* Built-in PowerVM*, so every E950/
E980 workload is virtualized with
accelerated secure Live Partition
Mobility (LPM), which compresses

The enterprise-class POWER9 processor boasts large-scale multisocket SMP, buffered memory attach,
2x to 4x the memory capacity of
POWER8*, reduced latency and improved throughput with enhanced
I/O support via on-chip PCIe Gen4
and integrated NVMe Flash (twice

Simplified Enterprise Cloud

then encrypts a workload image to
protect data in motion while quickly moving it to another system
Integrated PowerVC, IBM's
OpenStack-based cloud manager, for resource optimization and
private cloud management
Cloud Management Console entitlement for consolidated monitoring over multiple locations
Consistent enterprisewide multicloud management with VMware
vRealize Suite integration
IBM Cloud* Private suite of DevOps
tools and app store to create new
Power* cloud-native solutions

POWER9 clouds provide many benefits, including:
* Simplified transfer of VMs between
private and public clouds, which
enables hybrid use cases
* Cloud-ready Power software images to facilitate rapid workload
provisioning
* Broader availability of term licenses and Software as a Service pricing for Power software and tools
* Dynamic resource management,
within a system via Capacity on
Demand, and across multiple Power cloud servers via Power Enterprise Pools. Pools capabilities even
allow for seamless integration of
servers from different generations
of POWER within a cloud.

Enhancements to
Virtualization
George Gaylord, IBM offering manager for high-end Power Servers,
explains the granularity of virtualization on IBM Power Systems. "You
can create a VM that is as small as a
tenth of a core, and move resources between VMs as granularly as a
hundredth of a core and a megabyte
of memory," he says.
On larger, enterprise-class systems, flexibility increases even more.
"Not only can clients share more resources across more VMs and larger
VMs to support workload balancing
