 ENUS101-278.PDF (28KB)


At a Glance

The IBM Integrated Facility for Linux (IFL) on Multiprise 3000:

  • Provides a S/390 platform solution for Linux
  • Provides an optional Linux workplace independent of the traditional S/390 workload
  • Enables you to purchase additional processing capacity for your Linux workload with no effect on model designation
  • Enables you to run many Linux images on the Multiprise 3000 often without affecting your existing software bill
  • Simplifies administration and reduces cost for multi-Linux server environments by sharing system resources

Overview

Linux is one of the fastest growing operating systems in the world, providing a UNIX®-like application environment with a wealth of available applications. If you want to run either a single image or multiple Linux images, you will appreciate the new IBM Integrated Facility for independent Linux workspaces available on the Multiprise® 3000 .

Previously, this optional facility was only available on the IBM e(logo)server zSeries Server and the S/390® Parallel Enterprise server G5, and G6. Now you can purchase additional processing capacity, exclusively for Linux workload, with no effect on Multiprise 3000 model designation.

You can run Linux natively as a stand-alone or as a logical partition (LPAR) on a zSeries 900 and S/390. In addition, the S/390 Virtual Image Facility™ for Linux, and z/VM™ V4 enable you to run more Linux images than can be deployed using LPARs and provide capabilities to help create and manage these images. Now you can isolate Linux applications on the Multiprise 3000 in their own workspace. Using the IBM Integrated Facility for Linux, the new hardware feature on the Multiprise 3000, you can provide capacity dedicated to Linux workload.

The standard processor configuration of the model H30 with IFL feature is:

  • A uniprocessor running at H30 performance
  • A uniprocessor configured as the IBM Integrated Facility for Linux and running at H50 performance
  • One SAP
  • 4 GB Real Memory (available for all LPARs)

Description

Linux is a genuinely open system and that's the reason why it makes application portability a reality. There already exists many applications for Linux on S/390. These are available from IBM, ISVs, or as open source products. In most cases, these applications can be brought to S/390 with a simple recompile. This rapid application portability gives you real flexibility in optimizing your development and deployment platforms.

In addition to running Linux natively as stand-alone or as a logical partition (LPAR) on a zSeries 900 and S/390, IBM provides two operating systems that provide the capability to consolidate Linux workload on a single zSeries 900 and S/390 server. The S/390 Virtual Image Facility for Linux is an entry level product that offers a complete server environment for multiple Linux systems on a single server. Refer to Software Announcement 200-261 , dated August 1, 2000, for more information on the S/390 Virtual Image Facility for Linux.

If you want to create and improve the management of Linux images, then z/VM virtualization technology may be right for you. z/VM provides the capability to create a significant number of Linux images either within a logical partition or natively on Multiprise 3000. Centralized management and operation on a single server, while running multiple Linux images, reduces complexity, eases administration, and may lower costs.

The number of Linux images is limited, based on the Multiprise 3000 system capacity and the characteristics of the Linux workloads. z/VM virtualization technology enables you to:

  • Consolidate multiple applications on one piece of hardware, though not necessarily on a single Linux instance
  • Isolate applications from each other
  • Dynamically create additional Linux images as needed
  • Manage the Linux environment
  • Automatically exploit expanded storage
  • Test new distributions or versions of Linux while running older versions in production
  • Favor certain images by giving them greater access to resources

For additional information on the capabilities of z/VM and how it may help you consolidate Linux workloads within an S/390 Multiprise 3000 environment, refer to:

  • Software Announcement 200-358 , dated October 3, 2000, z/VM V3R1.
  • Software Announcement 201-163 , dated May 29, 2001, z/VM V4R1.

The IBM Integrated Facility for Linux

This optional facility, now available on the Multiprise 3000 servers, enables you to purchase additional 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. In addition, it will have 4 GB of memory available.

Consequently, executing Linux workload on the IBM Integrated Facility for Linux often will not result in any increased IBM software charges for z/OS™, OS/390®, VM, VSE, or TPF operating systems/applications. 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 operating in conjunction with z/VM or VIF are supported by the IBM Integrated Facility for Linux. One IBM Integrated Facility for Linux can be ordered either for a Multiprise 3000 model H30 or 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 (IFL) is an optional feature available for use with PR/SM™ to run Linux workloads. The IFL may be dedicated to a single Linux-mode logical partition or it may be shared by multiple Linux-mode logical partitions. In a Multiprise 3000, the general purpose CP and the IFL are independent resources. A given logical partition can be given access to either the IFL or the general purpose CP but not both at the same time. You can share these resources independently. The installation of features is disruptive, and it will require a 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.

Benefit from IBM Integrated Facility for Linux on Multiprise 3000 and z/VM

The IBM Integrated Facility for Linux, together with z/VM Virtualization Technology, enables you to:

  • Add processing capacity dedicated to running Linux on models H30 and H50 of your Multiprise 3000 server
  • Run multiple Linux images on an IFL-configured z/VM system often without affecting the software fees of your existing S/390 environment. z/OS, Linux, OS/390, z/VM, VM/ESA®, TPF, or VSE/ESA™ customers can add z/VM V4 to their environment and only pay a z/VM price that corresponds to the number of engines
  • Define multiple virtual Linux images on fewer real Multiprise 3000 resources

Performance

System performance depends on the hardware resources allocated to the IBM S/390 Integrated Facility for Linux, on the type of work, and on the level of activity within each Linux image. The IFL processor will perform at the H50 performance level. It is recommended that when considering LAN network connectivity the number of simultaneous connections be limited to four or less. If your applications require more than the integrated I/O LAN Adapter features can deliver, one should consider using an ESCON® channel-attached controller. For assistance in understanding the performance implications for a particular environment, contact your IBM representative or your IBM Business Partner.

Limitations: The number of Linux images that one may create and implement may be limited based on:

  • The availability of disks, central storage, and expanded paging resources
  • Network capabilities
  • Hardware resources allocated to the S/390 Integrated Facility for Linux
  • The type of work and the level of activity within each Linux image.

The Linux solution on Multiprise 3000 servers are positioned as the "entry" solution for Linux on S/390 servers. It is targeted to small to medium business integration scenarios and the easy Web-enablement of existing applications together with the consolidation of a small number of discrete workload servers.

Product Positioning

The IBM Integrated Facility for Linux enables the fast implementation of Linux workload on S/390 with no impact on the model designation and often little or no impact on a customers' existing software bill. With the availability of the IBM Integrated Facility for Linux or 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.

The Multiprise 3000 solution is targeted for existing S/390 customers requesting an entry offering to run Linux on S/390. This will give the advantage of Linux applications accessing enterprise data where it's stored, improving responsiveness and reducing unnecessary duplication of data. S/390's capacity and it's qualities of service make it the perfect platform to help simplify operations and reduce costs by cutting the number of servers in a business. As result of being an open system, there are many applications written for Linux which can be brought to S/390 with a simple recompile in most cases. Just a few examples of these low cost applications include consolidation of file/print serving, Web-serving, and e-mail servers.

Together with z/VM virtualization technology, the IBM Integrated Facility for Linux enables you to run a large number of Linux server images on a Multiprise 3000 server and more images than supported by the IBM S/390 LPAR mode of operation. This technology allows you to transparently share CPU, memory and I/O subsystems so that each application developer and/or host production system can have their own Linux server environment on the same S/390.
