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,
