Integrated Facility For Linux (IFL) on
Multiprise 3000
The IBM Integrated Facility for Linux (IFL) on Multiprise
3000 is designed to enable the fast implementation of
Linux workload on S/390 with no impact on the model
designation, and sometimes with little or no impact on a
customer’s existing software bill. With the availability of
the IBM Integrated Facility for Linux on Multiprise 3000
servers, all S/390 customers can use the advantages of
Linux for S/390 solutions integrated with the existing
business applications on S/390.
This optional facility enables you to purchase addi-
tional processing capacity exclusively for Linux
workload, with no effect on the Multiprise 3000 model
designation. For example, a Multiprise 3000 model
H30, with additional workspace added by the IBM
Integrated Facility for Linux, will still report its S/390
capacity as a model H30.
Consequently, executing Linux workload on the IBM
Integrated Facility for Linux on Multiprise 3000 will not
result in any increased IBM software charges for z/OS,
OS/390, VM, VSE, or TPF operating systems / applica-
tions. Moreover, your independent software vendor
(ISV) who provides S/390 applications to you, may be
among those ISVs who have adopted this policy for
the hardware workspace dedicated to Linux.
Installations should note that the Linux workspace
enabled by this facility will not support any of the S/
390 traditional operating systems (z/OS, OS/390, TPF,
VSE, or VM). Only Linux applications or Linux operat-
ing in conjunction with z/VM™ are supported by the
IBM Integrated Facility for Linux. One IBM Integrated
Facility for Linux can be ordered for Multiprise 3000
model H30 and H50. On the model H70, the second
processor is already in use, and therefore cannot
have the hardware feature for Linux installed.
The IBM Integrated Facility for Linux on Multiprise
3000 is managed by PR/SM as a logical partition with
dedicated CPs. This configuration is allowed pro-
vided that both the CP and the IFL are defined as
"shared". The installation of features is disruptive, and
it will require an LPAR definition, following normal
LPAR activation procedure. As with any change in the
LPAR configuration of a processor, the introduction of
additional resources to manage may have an impact
on the capacity of the existing partitions and
workloads running on the server.
