CURRENTS

consolidated on a z13s system;
on-premises, x86-based
systems; and off-premises,
x86-based public cloud.
Various cost elements related
to infrastructure, middleware
and labor were included in
the overall three-year TCO (see
Table 1, page 7). The three-year
TCO for z13s deployment is
estimated to be 45 percent lower
than the compared on-premises
x86 deployment and 55 percent
lower than the off-premises
public cloud alternative (see
Figure 1, right).
This case illustrates how
lower middleware costs are a
significant advantage in the
case of the IBM z13s platform
in terms of overall TCO. With
z13s servers, the workloads can
be consolidated on a smaller
footprint, which results in more
than 4x lower middleware costs
compared with the other two
x86-based alternatives (see
Figure 2, right).
Many middleware products
are priced per core; therefore,
consolidating on a smaller
number of cores (smaller
footprint) results in lower
middleware costs in the case
of the z13s platform. Also, a
consolidated and simplified
Linux infrastructure on z13s
results in lower labor costs (in
managing the infrastructure)
compared with an on-premises,
x86-based environment where
a larger infrastructure (e.g.,
with multiple servers) needs to
be managed.

Competitive
Price Point

The IBM z13s offers a superior
enterprise-grade platform for
consolidating a variety of Linux
workloads at an economic price
point, which will be difficult to
find in competing x86-based
alternatives or public cloud
solutions.

LEGAL DISCLAIMER FOR FIGURE 1 AND FIGURE 2 (ABOVE)
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.
