Server-to-Server high Speed Communications using RoCE Remote Direct Memory Access (RDMA) over CEE (RoCE) • To improve transaction rates we provide an I/O card to reduce latency and improve throughput by eliminating most of the TCP/IP software stack overhead for: – DB2, IMS, CICS, WAS – TCP applications sensitive to network latency, affecting response time – Emerging workloads such as business analytics – Oracle RAC (using RDS) – DB2 PureScale® clustering (using RAPL) • Built on Shared Memory Communication-Remote (SMC-R) architecture for low latency and high speed communication between servers running TCP sockets – Read/write to peer memory buffers using RDMA operations without application changes • Utilizes native PCIe and RDMA interfaces in hardware and Linux operating system – Supports applications/middleware written to exploit interfaces • Interactive workload performance potential: 50% latency reduction, 15-20% CPU savings • Streaming (bulk data) workload performance potential: 100% throughput improvement, 50% CPU savings • Initial support with z/OS V2.1; IBM intends to extend to other platforms over time

SMC-R RDMA Update

RDMA over Converged Ethernet RoCE Support for SMC-R • Requires z/OS V2.1 running on zEC12, zBC12 servers with the RoCE Express feature • Shares memory between peer z/OS images • Read/write access to the same memory buffers without application changes • Designed to help increase transaction rates with low latency and reduced CPU cost • RMF support with new SMF74-9 records and PCIE Activity Report • Java support planned – For future updates of IBM 31-bit and 64-bit SDK for z/OS Java Technology Edition, Version 7 (5655-W43 and 5655-W44)

Silvio Sasso's Corner, GSE z/OS Expertforum CH #81, 21.-22.10.2014, Bad Ragaz 23 SMC-R RDMA Update

RDMA (Remote Direct Memory Access) Technology Overview • Key attributes of RDMA – Enables a host to read or write directly from/to a remote host’s memory without involving the remote host’s CPU • By registering specific memory for RDMA partner use • Interrupts still required for notification (i.e. CPU cycles are not completely eliminated) – Reduced networking stack overhead by using streamlined, low level, RMDA interfaces – Key requirements: • A reliable “lossless” network fabric (LAN for layer 2 data center network distance) • An RDMA capable NIC (RNIC) and RDMA capable switched fabric (switches)

Host A Host B

MemoryA CPU MemoryB CPU

RNIC RNIC Rkey A RDMA enabled network Rkey B fabric

SMC-R RDMA Update

RoCE - RDMA over Converged (Enhanced) Ethernet • RDMA based technology has been available in the industry for many years – primarily based on Infiniband (IB) – IB requires a completely unique network eco system (unique hardware such as host adapters, switches, host application software, system management software/firmware, security controls, etc.) – IB is popular in the HPC (High Performance Computing) space • RDMA technology is now available on Ethernet – RDMA over Converged Ethernet (RoCE) – RoCE uses existing Ethernet fabric but requires advanced Ethernet hardware (RDMA capable NICs and RoCE capable Ethernet switches) – RoCE is a game changer! • RDMA technology becomes more affordable and prevalent in data center networks • Host software exploitation options fall into two general categories: – Native / direct application exploitation • Several variations, all involve deep level of expertise in RDMA and a new programming model – Transparent application exploitation (e.g. sockets based) • Improve Time To Value by automatically exploiting RDMA/RoCE for sockets based TCP applications

zEC12 I/O Interrrupt Delay Time

zEC12 I/O Interrrupt Delay Time • Response Time Components

• The response time that is reported for a device is the sum of IOS QUEUE time, PENDING time, CONNECT time and DISCONNECT time

• However, there is another response time component that was not measured and reported but impacts the overall I/O response time as seen by the application:

• The I/O Interrupt Delay time

• Interrupt Delay time is the time between when the I/O completes and z/OS issues the TSCH instruction to retrieve the results, in other words: • How long does it take for z/OS to see and process the interrupt after I/O completes?

Silvio Sasso's Corner, GSE z/OS Expertforum CH #81, 21.-22.10.2014, Bad Ragaz 34 zEC12 I/O Interrrupt Delay Time

zEC12 I/O Interrrupt Delay Time… • There are two possible reasons for an I/O interrupt delay:

• An LPAR is not dispatched • There are not enough CPs that are enabled to handle interrupts • I/O interrupt delay time is NOT included in the total I/O response time as reported by RMF • In the past I/O interrupt delay time could not even been measured • When data transfer is complete on an I/O device, the channel subsystem will attempt to find a CP (idle or busy) that is enabled for interrupts

• After the CP completes processing for an I/O interrupt, it issues a Test Pending Interrupt (TPI) instruction to determine whether there are any further I/O interrupts pending

• If yes, the processor proceeds to service that interrupt • Hence, an interrupt handled via TPI is a queued interrupt , that could not be handled instantly by an alternate I/O enabled processor

• High ratios of interrupts handled via TPI (Test Pending Interrupt) are an indicator for significant I/O elongation • Not more than 20-30% should be handled via TPI, otherwise it is time to examine the I/O interrupt delay time

zEC12 I/O Interrrupt Delay Time

zEC12 I/O Interrrupt Delay Time… • RMF CPU Activity Report Sample:

zEC12 I/O Interrrupt Delay Time… • z/OS V1.12 and V1.13 RMF is extended to report the interrupt delay time measurement for devices attached to the IBM zEnterprise EC12 server • Support available with new function APAR OA39993 • New field AVG INT DLY in RMF Postprocessor Device Activity report

• Caution: Interrupt Delay Time is not included in AVG RESP Time

AVG INT DLY: The average interrupt delay time in units of milliseconds encountered for I/O requests to this device. For each I/O request, the time is measured from when the I/O operation is complete to when the operating system begins to process the status.

zEC12 GA2 LPAR Group Capping

Change of LPAR Group Capping with zEC12 GA2 • It is possible to combine IRD weight management with capacity groups

• IRD changes the current weight in order to shift capacity within an LPAR cluster • However, IRD weight management gets suspended when capping is in effect • Because entitlement of an LPAR within a capacity group is currently derived from the current weight the LPAR might get stuck at a low weight

– Consequently, a low group capacity entitlement can result • On a zEC12 GA2, the initial LPAR weight will be used for group capacity • Only if all systems in a capacity group are – z/OS V2.1, or – z/OS V1.12, V1.13 with OA41125 applied

• Results in more predictive and better controllable group capacity entitlement

IBM System z Update on zIIP and zAAP Specialty Engines

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” (“AUT”) provided at www.ibm.com/systems/support/machine_warranties/machine_code/aut.html

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.

zAAPs and zIIPs

System z Integrated Information Processor (zIIP ) zIIP is a special purpose processor introduced to relieve central processors of running specific DB2 ® processing loads, but is now set to offload processing of many other z/OS ® workloads, as well. As more work runs on zIIPs, fewer processing units are consumed on CPs, resulting in lower software bills for clients.

IBM System z Application Assist Processor (zAAP) Engines are designed to run specific Java ™ and XML workloads under z/OS. Customers do not incur software license charges for their zAAPs, reducing their costs of running Java and XML applications.

Note: zAAP/zIIP engines contain the same underlying hardware as any other mainframe engine. They also always run at 100% full capacity of the processor even on sub-capacity server models.

z/OS V2.1 Migration Book Refresh drives a Workflow Update Introducing another Advancement in z/OS Migration Assistance!

• We have moved the z/OS V2.1 Migration book into a z/OS Management Facility (z/OSMF) z/OS 2.1 Migration Workflowl • Using the z/OSMF workflow, you can go through a z/OS V2.1 migration as an interactive, step-by-step process • There are two Workflow XML documents provided: one for a migration from z/OS V1.13 to V2.1, and one for a migration from z/OS V1.12 to V2.1 • Select the Workflow XML document you need • The Workflow XML documents are identical to the z/OS V2.1 Migration Book (GA32-0889-02), meaning the book contains identical information to the Workflow XML documents and the Workflow XML documents contain identical information to the book http://publibz.boulder.ibm.com/epubs/pdf/e0z3m102.pdf • You could, if you wish, completely replace the book with the z/OSMF Workflow! • As the z/OS V2.1 Migration book is updated, the corresponding z/OSMF Workflow documents are also updated • Check the level of the Workflow document to see what the corresponding level of the book is

z/OSMF z/OS 2.1 Migration Workflow

z/OS V2.1 Migration Book Refresh drives a Workflow Update… • Even though z/OSMF V2.1 is a prerequisite for using this z/OS V2.1 migration information, and there is a “chicken and egg” problem, there are still some benefits to using the z/OS V2.1 migration workflow files now: • The z/OS V2.1 post-installation migration actions can be assigned and tracked, once you have z/OSMF V2.1 up and running • You can determine if you have missed any z/OS V2.1 migration actions, by using the workflow to ensure that you didn't overlook any applicable actions • You can learn how to maneuver in the z/OSMF Workflow early, so that subsequent migration use of Workflow is familiar to you • You can provide early feedback on exploiting z/OS V2.1 migration with z/OSMF Workflow – This can help improve any follow-on deliverables for z/OS migration that may come • You can identify any wish list items that would be helpful for z/OS migration within the z/OSMF Workflow itself • This tool is not supported by the IBM Service organization but rather by the tool owner on a best-can-do basis • Please report any problems, suggestions, or comments to: [email protected] • For more information on the z/OSMF z/OS 2.1 migration workflow: http://www-03.ibm.com/systems/z/os/zos/tools/downloads/zosmf-zos-v2r1-migration-workflow.html

IBM WebSphere Liberty z/OS Connect Secure and consistent Enterprise Connectivity for Mobile Ships with WAS, CICS, and IMS • Designed for z/OS – builds on z/OS qualities of service, Auditing, chargeback • Unifies Connectors – a common solution for mobile, cloud, and web • Simplified Integration – Hide complexity of connecting to z/OS using REST • Discover z/OS Assets – Enhance user experience by exposing z/OS data

System z in a Mobile World

IBM WAS Liberty z/OS Connect – Setting Context • This is about getting REST and JSON into your mainframe environment in a way that enables you to best take advantage of the assets that exist there:

•Liberty Profile Server •Function IBM wrote to run in Liberty Profile REST – Representational State Transfer … •No charge function provided with license Other the use of HTTP URLs that map to a entitlement to WAS z/OS, CICS or IMS ‘service’, such as ‘query account’ or ‘update data’

JSON – JavaScript Object Notation … a standard of representing data as a set of name/value pairs. This is passed back and forth along with REST request/responses

Silvio Sasso's Corner, GSE z/OS Expertforum CH #81, 21.-22.10.2014, Bad Ragaz 56 System z in a Mobile World

There are Already Ways of Handling REST/JSON • There are already ave ways of exposing z/OS resources through REST APIs and using JSON … most notably:

Roll your own REST is essentially HTTP, and JSON can be handled by WebSphere Application Server or Liberty … so you could write your own handler to take in REST/JSON and connect to backend resources

CICS CICS and the Mobile Feature Pack provides a mechanism for a CICS region to consume REST/JSON and provide access to CICS programs

IBM Worklight A comprehensive Mobile Enterprise Application Platform (MEAP) … but Worklight is not supported on z/OS (is supported on Linux for System z)

What z/OS Connect provides is a common and consistent REST/JSON interface to the mainframe

System z in a Mobile World

Why z/OS Connect? • This represents another component to configure and maintain in your environment So what value does it bring?

• Provides a common and consistent entry point for mobile access to one or many backend systems • Java, so runs on specialty engines • Shields backend systems from requiring awareness of RESTful URIs and JSON data formatting • Provides point for authorization of user to invoke backend service • Provides point for capturing usage information using SMF • Simplifies front-end functions by allowing them to pass RESTful and JSON rather than be aware of or involved in data transformation You could enable Mobile access without z/OS Connect

z/OS Connect simplifies and makes the environment more consistent and manageable

Silvio Sasso's Corner, GSE z/OS Expertforum CH #81, 21.-22.10.2014, Bad Ragaz 57 System z in a Mobile World

Different Delivery Approaches • This is planned to be delivered with WAS z/OS, CICS and IMS … objective is to provide different approach paths depending on what you have:

WAS z/OS Delivered as function that runs inside Liberty Profile z/OS - Initially will use WOLA (WebSphere Optimized Local Adapters) to access backend

CICS To be delivered as part of Liberty Profile that runs inside of CICS region - Will use JCICS interface to access CICS functions

IMS Initially this ends up looking just like the WAS z/OS approach: that is, Liberty Profile z/OS with z/OS Connect inside. Difference is this: IMS z/OS Connect uses JCA* to talk to IMS Connect to get access into IMS.

These different delivery mechanisms tend to obscure the main story of what it is and how it works, so for now let’s stipulate IBM offers several ways to get this and now focus on some details

* A supplied IMS JCA resource adapter, as opposed to the local adapter support

System z in a Mobile World

Context within overall Mobile Architecture The message here is that z/OS Connect is a piece of the Mobile architecture, but in most cases will not be the only component:

Users of z/OS Connect would z/OS Connect would be access through normal corporate behind the secure firewall infrastructure IBM Worklight to provide firewall, and on LPARs application management, security along with backend and operational governance for systems mobile applications

System z addresses Enterprise Mobile Development and Delivery Challenges

Fragmentation and developing for multiple IBM Worklight Studio and RDz mobile platforms • Seamless integration with z data and transactions • Highly fragmented set of devices, platforms, languages, and tools complicates • Device runtime provides mobile development, test, and operations device independence

Accelerated time to market requirements System z Scalability • Accelerated development demands instant • System z Linux cloud enables rapid provisioning of development servers provisioning of Worklight servers • Spikey mobile traffic demands highly • z/OS is the leader in transaction scalable cloud-based infrastructures, for processing and easily scalable to both SoE and SoR handle workload increases

Connecting apps with existing z/OS is mobile enabled enterprise systems • z/OS subsystems are mobile-ready, • Apps typically need to leverage existing with consumability enhancements enterprise services, which must be made planned. Eg: MongoDB API for DB2 mobile-consumable, and remain secure • End to end mobile security • Enterprise systems must be able to instantly • High-performance access from z/Linux provision new services and environments

System z in a Mobile World

System z Unique Characteristics to support Mobile Applications ° Easy-to-consume APIs from CICS, DB2, IMS allow you to leverage your investment in z/OS transactions to quickly add a mobile channel ° z/OS enables massive and simple scalability in a single footprint, to handle the workload of millions of devices and sensors ° Worklight security integrates with z/OS security providing end-to-end security and data privacy for mobile apps ° z/OS Workload Management ensures your crucial applications remain responsive during sharp spikes in demand

° Low-latency access to critical enterprise data. Mobile usage patterns favor short, read-only data requests (Users check account balances) So fast access to operational data, with low latency, is key. The mainframe offers exceptional I/O with dedicated hardware I/O processors. This reduces latency, which increases mobile app response times. ° Business Resiliency for critical mobile apps

“70% of mobile applications touch a mainframe system” Infrastructure matters for mobile applications. The System z platform’s scalability, security, and resilience can enhance critical mobile applications.

Silvio Sasso's Corner, GSE z/OS Expertforum CH #81, 21.-22.10.2014, Bad Ragaz 59 System z in a Mobile World

Why run Worklight Server on System z Linux? For the same reasons you run web apps there for over a decade: ° Co-location of the Worklight server application with data and transactions on z/OS reduces the latency of access to z/OS data . Hipersockets provides the lowest latency communication between Worklight apps and z/OS SOR. Hipersockets eliminates the need to encrypt traffic between Worklight and z/OS. ° Availability and scalability of z/Linux as an environment for both Worklight dev/test and production ° Hardware encryption speeds SSL applications ° All the traditional advantages of consolidating multiple distributed servers onto z/Linux -- Reduce data center footprint, WAS software license savings, simpler management, energy savings

We recommend running Worklight Server in System z Linux for data-rich applications that will heavily leverage data and transactions from z/OS. See this wiki for more rationale for WL on z.

Silvio Sasso's Corner, GSE z/OS Expertforum CH #81, 21.-22.10.2014, Bad Ragaz 92 ESAIO: A new Testing Tool for FICON Channel Cabling

New I/O Tooling for Testing a FICON I/O Configuration FICON is getting faster and faster

We can probably expect even faster FICON in the future, right? Of course

The faster fiber channel link speeds are more and more sensitive to the quality of the optical cabling infrastructure. As clients have transitioned from the initial one gigabit per second fiber channel link speeds to two, four and eight gigabit per second link speeds IBM product engineering (the field service team) has observed more frequent client complaints about the increase of I/O errors (interface control checks, IFCC) and the difficulty in detecting the problems before production work is up and running

The quality of the links can degrade due to bending or twisting of the fiber cables, or possibly if the dust covers are left off the optics while upgrading equipment

In many cases clients have been careful managing the cables and connections, but the faster links are more sensitive and errors occur where they do not happen at lower speeds

IBM System z is bringing a new Enterprise Class of quality to FICON channel in order to help a smooth transition to the faster link speeds

ESAIO: A new Testing Tool for FICON Channel Cabling

New I/O Tooling for Testing a FICON I/O Configuration… System z has provided new tooling, the IBM System z I/O Exerciser (ESAIO), to simplify the chore of exercising the I/O connections in the I/O configuration before running production work

This tool is intended to help identify possible cabling or definition errors by validating that all the paths defined to each device actually connect to the same physical device

Additionally, a data transfer stress test is performed to help verify the quality of the cabling infrastructure

These tests are especially useful after major infrastructure upgrades (e.g., push/pull of a new processor, data center move, replacing storage devices)

By running ESAIO before IPLing an operating system and starting a production workload, clients can avoid disruptions to production and insure that the correct set of devices is put in use

ESAIO can be installed to run in either a native System LPAR or in a z/VM environment

The tooling is available at no additional charge from IBM: https://www.ibm.com/services/forms/preLogin.do?source=swg-beta-ibmioexzos

P.S. Get the most out of FICON by implementing System z High Performance FICON - zHPF!
