............................................................................................................................................................................................. 107 z13s Hardware What is the machine type of the IBM z13s? The z13s machine type is 2965. What z13 models were announced? The z13s is available in two models – the N10 and N20, the model naming indicating how many total processor units are available for client purchase and characterization. The N10 can be configured with up to 10 configurable cores and up to 1 TB of memory. The N20 can be configured with up to 20 configurable cores and up to 4 TB of memory. The cores for characterization can be configured as general purpose processors (CPs), Integrated Facilities for Linux (IFLs), z System Integrated Information Processors (zIIPs), Internal Coupling Facilities (ICFs), additional System Assist Processors (SAPs), or used as additional spares. With up to 6 CPs and 156 available capacity settings offered across either model, you have the freedom to choose the right capacity setting for your needs with the flexibility to scale on demand as workload requirements increase. We also offer both IFL only and ICF only configurations where you can have up to ten or twenty IFLs or ICFs in a standalone environment. How much capacity will the z13s deliver? The z13s offers a maximum of 6 CPs with the range up to 7123 millions of instructions per second (MIPS)1 in a single footprint or 1.4x the capacity of the zBC12. For Linux® the z13s contains up to 20 IFLs for Linux specialty engines – 2.1x that of the zBC12. Where can I find the MIPS ratings for z13s? IBM z Systems provides capacity comparisons among processors based on a variety of measured workloads which are published in the Large System Performance Reference (LSPR). We don’t provide MIPS but we do provide Processor Capacity Index (PCI) values. They can be found at: https://www.ibm.com/servers/resourcelink/lib03060.nsf/pages/lsprindex 1 Based on preliminary internal measurements and projections. Official performance data will be available upon announce and can be obtained online at LSPR (Large Systems Performance Reference) website at: https://www-304.ibm.com/servers/resourcelink/lib03060.nsf/pages/lsprindex?OpenDocument . Actual performance results may vary by customer based on individual workload, configuration and software levels. Did IBM increase the number of logical partitions (LPARs) available on the z13s? Yes. There are now up to 40 logical partitions (LPARs) available for use versus 30 on the IBM zEnterprise® BC12 (zBC12). This will allow clients to support more ‘isolated/separate’ workloads on a single footprint. How many HiperSockets™ will be available on the z13s? There will still be 30 HiperSockets available. Please review the new Shared Memory Communications – Direct Memory Access (SMC-D) in the I/O section of the FAQs for information about a new inter-system communications protocol and their relationship to HiperSockets. Why are there are door locks on the new z13s? Yes. The front and rear doors will arrive with the door lock installed. There have been client requests for security rules for servers, for cryptographic features and for external auditors. The decision was made to have them on all servers. The use of the door locks is up to the client choice. Each door will come with two keys. If the doors are locked, then the client is responsible for unlocking the doors for IBM to perform service. IBM support personnel will not have ‘master’ keys. How many spare processing cores are on the z13s? There are two ‘dedicated’ IBM provided spares on the model N20 only. Unused or unassigned engines on either the N10 or N20 can be used as spares. Can any of the spare processing cores on the z13s be used for other purposes? No, the minimum allotment of spare cores is exclusively reserved to provide automatic failover in the extremely unlikely event of a processor failure. The spare cores protect all processor types (CPs, SAPs,

  • Introducing Linux on IBM Z Systems IT Simplicity with an Enterprise Grade Linux Platform
    Introducing Linux on IBM z Systems IT simplicity with an enterprise grade Linux platform Wilhelm Mild IBM Executive IT Architect for Mobile, z Systems and Linux © 2016 IBM Corporation IBM Germany What is Linux? . Linux is an operating system – Operating systems are tools which enable computers to function as multi-user, multitasking, and multiprocessing servers. – Linux is typically delivered in a Distribution with many useful tools and Open Source components. Linux is hardware agnostic by design – Linux runs on multiple hardware architectures which means Linux skills are platform independent. Linux is modular and built to coexist with other operating systems – Businesses are using Linux today. More and more businesses proceed with an evolutionary solution strategy based on Linux. 2 © 2016 IBM Corporation What is IBM z Systems ? . IBM z Systems is the family name used by IBM for its mainframe computers – The z Systems families were named for their availability – z stands for zero downtime. The systems are built with spare components capable of hot failovers to ensure continuous operations. IBM z Systems paradigm – The IBM z Systems family maintains full backward compatibility. In effect, current systems are the direct, lineal descendants of System/360, built in 1964, and the System/370 from the 1970s. Many applications written for these systems can still run unmodified on the newest z Systems over five decades later. IBM z Systems variety of Operating Systems – There are different traditional Operating Systems that run on z Systems like z/OS, z/VSE or TPF. With z/VM IBM delivers a mature Hypervisor to virtualize the operating systems.

What are the benefits of virtualization? ▪ Simplification – use of standardized images, virtualized hardware, and automated configuration of virtual infrastructure ▪ Migration – one of the first uses of virtualization, enable coexistence, phased upgrades and migrations. It can also simplify hardware upgrades by make changes transparent. ▪ Efficiency – reduced hardware footprints, better utilization of available hardware resources, and reduced time to delivery. Reuse of deprovisioned or relinquished resources. ▪ Resilience – run new versions and old versions in parallel, avoiding service downtime ▪ Cost savings – having fewer machines translates to lower costs in server hardware, networking, floor space, electricity, administration (perceived) ▪ To accommodate growth – virtualization allows the IT department to be more responsive to business growth, hopefully avoiding interruption 3 © Copyright IBM Corporation 2018 Agenda • Benefits of
