2 Notice Regarding Specialty Engines (e.g., ziips, zaaps and IFLs): Any information contained in this document regarding Specialty Engines ("SEs") and SE eligible workloads provides only general descriptions of the types and portions of workloads that are eligible for execution on Specialty Engines (e.g., ziips, zaaps, and IFLs). IBM authorizes customers to use IBM SE only to execute the processing of Eligible Workloads of specific Programs expressly authorized by IBM as specified in the Authorized Use Table for IBM Machines provided at ( AUT ). No other workload processing is authorized for execution on an SE. IBM offers SEs at a lower price than General Processors/Central Processors because customers are authorized to use SEs only to process certain types and/or amounts of workloads as specified by IBM in the AUT. 2

Notes: Performance is in Internal Throughput Rate (ITR) ratio based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput that any user will experience will vary depending upon considerations such as the amount of multiprogramming in the user's job stream, the I/O configuration, the storage configuration, and the workload processed. Therefore, no assurance can be given that an individual user will achieve throughput improvements equivalent to the performance ratios stated here. IBM hardware products are manufactured from new parts, or new and serviceable used parts. Regardless, our warranty terms apply. All customer examples cited or described in this presentation are presented as illustrations of the manner in which some customers have used IBM products and the results they may have achieved. Actual environmental costs and performance characteristics will vary depending on individual customer configurations and conditions. This publication was produced in the United States.

7 z/vm Version 6 Release 3 Making Room to Grow Your Business Major enhancements for scalability and performance Support for larger amounts of real memory Increased processor efficiency z/vm z/vm z/vm z/vm z/vm z/vm z/vm z/vm z/vm z/vm 6.1 z/vm 6.2 z/vm 6.3 7

8 z/vm Version 6 Release 3 Large Memory Support Real memory limit raised from 256 GB to 1 TB Proportionately increases total virtual memory based on tolerable overcommitment levels and workload dependencies Removes reorder completely Virtual machine memory limit remains unchanged at 1 TB Paging DASD utilization and requirements change Improves ability to reserve storage for users and segments Expanded storage continues to be supported with a limit of 128 GB But our runs show it is better to spend that storage on central 8

9 z/vm Version 6 Release 3 HiperDispatch Improved processor efficiency Better n-way curves Supported processor limit of 32 remains unchanged Better use of processor cache to take advantage of cache-rich system design of more recent machines Two components: Dispatching affinity Vertical CPU management 9

10 z/vm Version 6 Release 3 xcat to be shipped and installed with z/vm xcat Extreme Cloud Administration Toolkit Allows for Provisioning Function added to xcat that will be ready for z/vm 6.3 Capture ability to capture a virtual machine into an image that can be deployed at a later time. Deploy ability to deploy an image from previously captured image data. Export ability to export an image from a local repository for retention or transmission elsewhere. Import ability to import an image (possibly created elsewhere) into the local image repository. Delete Image ability to remove an image from a local image repository. List ability to discover images in a local image repository and information about the images. This is of primary use to xcat. SMAPI xcat Open Stack IBM Tivoli Products 10

11 z/vm Version 6 Release 3 Other Items Enhanced dump speed is improved for both ECKD and SCSI FCP data router lets guest exploit DMA capability in FCP card Improvements in exploiting DS 8000, especially in PPRC unit checks LGR can move a guest that uses a port-based VSWITCH Support for OSA-Express5S devices Improvements in VSWITCH recovery and stall prevention Guest exploitation of Crypto Express4S SSL server upgrade to z/os 1.13 equivalency Linux dump can now include the NSS z/vm 6.3 cannot be managed by Unified Resource Manager (see SOD) We intend to have z/vm 6.3 evaluated wrt EAL 4+ and FIPS CMVP (see SOD) z/vm 6.3 is the last XSTORE release (see SOD) z/vm 5.4 customers: zec12 and zbc12 are your last processors (see SOD) 11

12 With z/vm 6.3 we want our customers to know that they are the focus of the release Key Takeaways z/vm 6.3 continues the investment into virtualization on System z such that it allows customers to easily deploy additional virtual server workload on System z. Efficiency is a key attribute of the release. Memory scalability to 1 TB and HiperDispatch to use our CPUs more effectively Consumability or ease of system use continues to be a very important aspect as we look to an open standards interface and to an enhanced GUI for system management 12 12
