Ibm ZVSE V4.2 User Manual

z/VSE Version 4 Release 2 brings the value
of innovative IBM System z technology to
VSE clients

z/VSE™ V4.2 is designed to deliver highest qualities of service for transactions and data.

z/VSE V4 is designed to address the needs of VSE clients with growing core VSE workloads and/or those
who wish to exploit Linux® on IBM System z® for new, Web-based business solutions and infrastructure
consolidation.

z/VSE is an important part of IBM’s mainframe portfolio for

smaller IBM mainframe clients with somewhat less demanding

requirements. At the risk of oversimplification, z/VSE is similar

to z/OS® but smaller and less complex.

z/VSE V4.2 supports the new IBM System z10 Business

Class™ (z10™ BC) and IBM System z10™ Enterprise

Class (z10 EC™), the IBM System z9® Enterprise Class

(z9® EC) and System z9 Business Class (z9 BC) servers, as

well as IBM eServer™ zSeries® 990, 890, 900 and 800.

z/VSE V4.2 operates in z/Architecture® mode only and sup-

ports 64-bit real addressing. It is designed to exploit up to

32 GB of processor storage.

z/VSE 4.2 doubles the number of VSE tasks to 512 and adds

an LDAP client. It supports Parallel Access Volumes (PAV) fea-

ture of the IBM System Storage™ series DS8000® and

DS6000™.

z/VSE 4.2 supports advanced functions of IBM System

Storage, including IBM System Storage DS8000 Full Disk

Encryption, DS8000 FlashCopy® SE (space efficient),

IBM System Storage SAN Volume Controller, as well as the

IBM System Storage TS4300 Tape Library and TS7700

Virtualization Engine—just to name a few.

z/VSE V4 offers Midrange Workload License Charge (MWLC)

pricing, including sub-capacity pricing for clients running on

IBM System z10 BC™, z10 EC, z9 EC and z9 BC servers.

IBM is delivering a new world class enterprise server designed

to address the broadest range of business needs.

System z10 servers provide new, innovative technologies that

deliver dramatic improvements in price/performance for new

workloads. On the z10 BC, the combined effect of up to

40% more capacity in IFL and a 50% lower price is up to a

65% price performance improvement versus its predecessor,

the z9 BC. The z10 servers extend System z leadership in key

capabilities with the delivery of expanded scalability for growth

and consolidation, improved security and availability to reduce

risk and improved flexibility to respond to changing business

requirements. System z10 servers are at the core of the

enhanced System z platform that delivers technologies that

businesses need today along with a foundation to drive future

business growth.

Easy as PIE—the z/VSE strategy

It is essential that z/VSE clients have the option of continuing

to use their core VSE solutions while at the same time they’re

adding new solutions, regardless to which platform. New solu-

tions should be able to leverage and exploit existing core

z/VSE applications and data.

The z/VSE strategy addresses these client expectations with—

PIE—the acronym represents:

●

Protect

●

Integrate

●

Extend

Protect focuses on investment protection. z/VSE clients

should be able to exploit the latest IBM System z and

IBM System Storage technology to enhance and grow core

z/VSE environments.

Integrate enables seamless integration. z/VSE clients should

be able to extend their core z/VSE information assets into their

overall IT networks.

Extend refers to adding new IT solutions. z/VSE clients should

be able to extend their core z/VSE solutions with solutions that

exploit the advanced, standards-based capabilities of any plat-

form, especially Linux on System z.

The “PIE strategy” is fundamentally based on an open, hybrid

model. This hybrid model can give clients the best of both

worlds: it helps them protect their z/VSE investments as they

exploit the capabilities of complementary platforms. Indeed,

z/VSE plus Linux on the System z platform is a compelling

combination.
