A “classic” might just be the best

Today’s market ﬁnds that business

needs ar

e changing, and having a com-

petitive advantage isn’t always about

having more or being bigger, but more

about being smarter and responding

faster to change and to your clients.

Often, being reactive to change has led

to infrastructures with mixed technolo-

gies, spread across an enterprise, that

are complex and difficult to control and

costly to manage. Integration of appli-

cations and data is limited and difficult.

Using internal information to make

insightful decisions for the company

can be difficult because knowing you

are using the “best” data—that which is

most current and complete—may not

be possible.

In many situations, investments have

been made in disparate technologies

that may fall short of meeting their

goals. Merging information fr

om one

branch to another may not be possible

and so company direction is set with

only a portion of the data at hand, and

in a global economy that can really hurt.

Companies need to be able to regain

control and create a uniﬁed infrastruc-

ture. The objective is to ﬁnd a strategic

platform to standardize on, one that’s

able to integrate and support a large

and diverse set of applications, and one

that has resources that can be shared

and optimized for maximum use. And

of course the goal includes the ability to

scale as the company grows, providing

a safe and security-rich level of

resource protection.

The System z9 mainframe is perfect to

take on that role. While having classic

strengths on which its reputation was

formed, it continues to be a leader in

areas such as data management, avail-

ability, security and resiliency, virtualiza-

tion and integration. Its ability to

support many open and industry stan-

dards, with comprehensive support for

Service-Oriented Architecture, makes it

an ideal platform for deploying new

workloads or for interoperating with

new workloads on alternative

technologies.

The System z9 Enterprise Class

(z9 EC), formerly the System z9 109

(z9-109), pr

ovides tight collaboration

with IBM storage and IBM software to

help achieve advanced I/O function and

performance. And while the z9 EC can

scale to of

fer a large capacity main-

frame in a single footprint, some cus-

tomers have requested the z9 EC

innovative features with more ﬂexibility

in customizing and sizing the capacity

of the general purposes processors

(CPs) that reside in the server. These

customers want more options as they

weigh business demands and costs,

trying to achieve the right balance. The

new subcapacity models of the z9 EC

satisfy these requests. These enhanced

capabilities illustrate that the z9 EC is a

classic that doubles as an advanced

solution designed to support the IT

infrastructure needed for today’s

on demand business.

Information on demand is the core of

your business

Data is at the core of every business.

Being able to integrate and merge data

om different databases can enable

businesses to provide timely, current

and correct information to their clients.

This type of delivery allows a business

to be responsive and ﬂexible to its

clients’ requests. Taking this a step fur-

ther, a business may beneﬁt from being

able to analyze the information for

insight, research or simulations. This

can help set corporate strategy and

allow a business to have a competitive

edge.

But data management can be a big

oject. It needs to be available globally;

it must be kept up in real time and

accessible 24x7. At the same time, it

needs to be protected from unautho-

rized access and to comply with new

regulations. The IBM System z™ main-

frame family has a strong heritage in

data serving, and its architecture is

designed for massive data access,

whether across the Internet, to storage

devices, or to remote backup sites.

Scalability, availability, security—these

are all core competencies of the

mainframe.

The z9 EC, like the predecessor

IBM mainframes, includes dedicated

I/O pr

ocessors (the System Assist

Processor or SAP) to manage thou-

sands of concurrent data accesses. It

provides more available channel band-

width and FICON channels than the

IBM eServer™ zSeries® 990 (z990).

The new MIDAW Facility on the z9 EC

can help improve FICON channel effi-

ciency and throughput. The new

enhanced book availability, redundant

I/O interconnect, channel subsystem

enhancements and enhanced driver

maintenance can increase the z9 EC’s

availability, helping to protect not just

the mainframe but also its applications

from unplanned as well as planned

outages.

The new System z9 Integrated

Information Processor (IBM zIIP)

specialty engine is designed to help

improve resource optimization and

lower the cost of portions of eligible

workloads. IBM DB2® for z/OS® V8

and above will exploit the zIIP capability

for portions of eligible workloads.

The zIIP can help to strengthen the

System z9 mainframe as the data

serving hub, helping customers to

more fully leverage their valuable

assets. In addition to supporting por-

tions of DB2 workloads, IBM plans to

announce an enhancement to the z/OS

Communications Server that allows the

IPSec processing to take advantage of

zIIP specialty engines. It is anticipated

that the zIIP will help reduce the overall

cost of IPSec processing.

Versatile design for optimized sizing

Offered on our IBM S/390® and

zSeries midrange servers since 1999,

subcapacity general purpose pr

oces-

sors have allowed customers to choose

a server sized to best meet business

requirements. This granularity and ﬂexi-

bility has been dramatically extended in

the midrange mainframe line in the past

few years and is now being offered on

the z9 EC. On the z9 EC, subcapacity

processors are available on servers

conﬁgured with eight or fewer general

purpose pr

ocessors. With the z9 EC

four book design, additional available

processors within the server can be

characterized as specialty engines

(ICFs, IFLs, zAAPs or zIIPs) or for

Capacity Backup Upgrade (CBU).

Although there is no change to the total

number of available pr

ocessors on the

z9 EC, customers will be able to

choose from four different subcapacity

settings when they run with eight or

fewer general purpose processors. The

z9 EC will now have a new lower entry

that is 66% smaller than the current

z9 EC entry and will offer 24 new

capacity settings. Once the requirement

for general purpose processors

exceeds eight, all general purpose

processors will be full capacity. All

functions and features of the z9 EC

are available when running with

subcapacity processors.

All mainframe customers now have the

option of selecting a server that meets

both total capacity r

equirements as well

as being able to select the number of

general purpose processors that best

ﬁts their application and processing

requirements.

Optimizing for better resource utilization

The IBM System z9 Integrated

Information Processor (IBM zIIP) was

announced in January 2006. The zIIP’s

execution environment will accept eligi-

ble work from z/OS 1.6 and above,

which will manage and direct the work

between the general purpose processor

and the zIIP. DB2 for z/OS V8 and

above will exploit the zIIP capability for

eligible workloads.

The zIIP is designed so that a program

can work with z/OS to have all or a

portion of its Service Request Block

(SRB) dispatched work dir

ected to the

zIIP. Types of eligible work that access

DB2 and that can have portions of

their work be directed to the zIIP

include CRM (Customer Relationship

Management), ERP (Enterprise

Resource Planning), BI (Business

Intelligence) and data warehousing

applications.

In addition to supporting portions

of DB2 workloads, IBM plans to

announce an enhancement to the z/OS

Communications Server that allows the

IPSec pr

ocessing to take advantage of

zIIP specialty engines. It is anticipated

that the zIIP will help reduce the overall

cost of IPSec processing.

All statements regarding IBM’s future direction and intent are subject to change or withdrawal without notice, and represent goals and objectives only.
