Answer: The new product name is IBM z13s™ (z13s). The ‗s‘ stands for single frame. In comparison, the IBM z13™ (z13) is a dual frame system. Question: What is the name of the server and the family name announced in 2015? Answer: The high end server that was introduced January 14, 2015 is IBM z13 (z13). The ‗13‘ signifies that this is the thirteenth generation of CMOS technology that started with the 9672 processor line we introduced in 1994. In addition, the IBM System z® family name has been replaced by IBM z Systems™ and encompasses every IBM Mainframe from S/360® through the new IBM z13s and any future systems. IBM z Systems is also the name of the new Product Line. The previous product line name was IBM zEnterprise®. Question: Why did IBM change the name? Answer: As the IBM z Systems for digital business matures and evolves, the family naming will continue to evolve along with it. We used the name change to signal evolution of the product line. In addition, we had found the previous names to be overly complicated and frequently there was inconsistent usage of IBM System z vs. IBM zEnterprise. This change modernizes our brand and product naming while maintaining brand equity in z and celebrating it. 3 z13s Hardware Question: What is the machine type of the IBM z13s? Answer: The z13s machine type is 2965. Question: What z13 models were announced? Answer: 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. Question: How much capacity will the z13s deliver? Answer: 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. Question: Where can I find the MIPS ratings for z13s? Answer: 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. 4 Question: Did IBM increase the number of logical partitions (LPARs) available on the z13s? Answer: 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. Question: How many HiperSockets™ will be available on the z13s? Answer: 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. Question: I hear there are door locks on the new z13s? Why are there door locks? Answer: Yes. The front and rear doors will arrive with the door lock installed. There have been client requests for security rules
