IBM z13s

On-premises
x86-based systems

Off-premises
public cloud

One IBM z13s system:
s 8 IFLs
s 384 GB memory
s KVM hypervisor running in 1 LPAR
s Suse Linux Enterprise Server (SLES)
as OS for workloads running in
1 LPAR
s IBM Storwize V7000
s 1.6 TB SSDs

Two x86 systems:
s 48 cores (24 cores per system)
s 384 GB memory (192 GB per system)
s KVM hypervisor running on
each system
s SLES as OS for workloads running
on 2 systems
s 1.6 TB internal SSDs (800 GB
per system)

24 virtual instances (in U.S. east):
s 48 virtural CPUs (2 virtural CPU
per instance)
s 192 GB memory (8 GB per instance)
s SLES as OS for instances
s 960 GB of persistent storage
(20 GB per instance)
s Total data transfer out of 2154 GB/day
s Enterprise support

24 VMs (2 VMs per workload):

24 virtual instances (2 virtual
instances per workload):

Cost Elements

Infrastructure

24 VMs (2 VMs per workload):
Middleware

s 12 VMs running WebSphere
Application Server Network
Deployment (ND)
s 12 VMs running DB2 Enterprise
Server Edition

Labor

Includes costs to manage
infrastructure and VMs

which guarantees continuous
availability, even in the rare
event of hardware failure.
Further, redundancy in the
memory subsystem is built-in
using the highly available
z Systems redundant array of
independent memory technology.
At the hypervisor level, there's
support for live guest migration
to help automate and speed
recovery from planned and
unplanned outages.

Figure 1: Cost-Effective

Middleware Efficiency
With the z13s, Linux workloads
can be consolidated on a
smaller footprint at a lower cost
compared with other x86-based
options. The latest IBM total cost
of ownership (TCO) study looks
at the cost to consolidate Linux
workloads on the z13s compared
with deploying them on-premises
on the leading x86 alternative or
using off-premises, x86-based
public cloud resources.
For this study, it's assumed
there are 12 Linux Web
workloads running 24-7. Each
workload is a two-tier Web
application consisting of two
VMs, where one VM is running

LEGAL DISCLAIMER FOR FIGURE 1 (ABOVE) AND FIGURE 2 (PAGE 14)
Performance comparison based on IBM internal tests comparing IBM z13s with one comparably
configured x86 environment and one comparably configured public cloud running general
purpose virtual machines designed to replicate typical IBM customer workload usage in the
marketplace. System configurations are based on equivalence ratios derived from IBM internal
studies and are as follows: Public Cloud configuration: total of 24 general purpose instances;
x86 configuration: total of two x86 systems each with 24 Intel E5-2690 v3 cores, 192 GB memory,
and 2x400 GB SSDs; z13s configuration: total of 8 cores, 384 GB memory, and Storwize v7000
with 4x400 GB SSDs. Price comparison estimates based on a 3YR Total Cost of Ownership
(TCO) using publicly available U.S. prices (current as of Jan. 1, 2016). Public Cloud TCO estimate
includes costs (U.S. East Region) of infrastructure (instances, data out, storage, support, free
tier/reserved tier discounts), middleware and labor. z13s and x86 TCO estimates include costs of
infrastructure (system, memory, storage, virtualization, OS), middleware and labor. Results may
vary based on actual workloads, system configurations, customer applications, queries and other
variables in a production environment and may produce different results. Users of this document
should verify the applicable data for their specific environment.
