TRENDS

delivering consistent subsecond
end-user response times.
Further, with superior workload
management capabilities,
IBM LinuxONE and Linux on
Z environments can enable
resources to be effectively
used by tens of thousands of
microservices, thereby achieving
the highest possible utilization of
the platform.
Recent studies at IBM have
shown that the LinuxONE
and Linux on Z environments
can deliver up to 2.4x more
throughput per core for
cloud-native applications
compared to running them on x86
1
commodity infrastructure .
Both systems are built to
operate with the highest levels of
reliability and availability. At the
hardware level, they ship with
redundant cores, which guarantee
continuous availability in the
event of hardware failure.
Further, redundancy in the
memory subsystem is built-in
using the highly robust redundant
array of independent memory
technology that can provide
protection from failures at
dynamic RAM, dual inline
memory module and memory
channel level. IBM LinuxONE
and Z memory subsystem sets the
gold standard for being among
the most resilient solutions in the
industry.
Like the previous generations,
the latest IBM LinuxONE and
Z mainframes can be split into
multiple LPARs. Within these

system can have
up to

170
cores housed in
industry-leading,
fast 5.2 GHz
10-core
processor chips

partitions, microservices/
containers can both be deployed
directly on them or they can
run inside a VM under z/VM or
Kernal-based VM hypervisors.
Resources can be either shared
or dedicated to individual LPARs,
with the flexibility to dynamically
scale up by adding resources
to partitions or scale out by
adding more partitions on the
system. Further, with the capacity
on-demand feature, resources
can be temporarily activated or
deactivated for short periods
of time to handle seasonal or
periodic fluctuations in workloads
in a very cost-effective fashion.
LPARs on IBM LinuxONE and Z
are EAL 5+ certified and can allow
for services to be run in highly
secure isolation on a single box.
For instance, as depicted in Figure
1, microservices environments

can be hosted for multiple tenants
on separate logical partitions on
the same system without risks,
thereby obviating the need for
having separate physical systems
as would be the case on other
commodity infrastructure.
And for ultimate protection of
data, high-performance encryption
capability for data, both at rest
and in flight, with integrated
cryptographic capabilities is built
in the hardware. Each processor
on IBM LinuxONE and Z has the
coprocessor Central Processor
Assist for Cryptographic Functions
(CPACF) that can perform
symmetric cryptographic and
hashing functions at more than
2x better throughput compared to
2
commodity platforms . Also, a FIPS
140-2 level 4 certified hardware
security module is on board for key
management and for providing
