This model helps reset the economics of IT and can dr[...]

Just-in-time deployment of IT resources Infrastructures must be mor e fl exible to changing capacity requir ements and provide users with just-in-time deploy- ment of resour ces. Having the 16 GB dedicated HSA on the z10 EC means that some preplanning confi guration changes and associated outages may be avoided. IBM Capacity Upgrade on Demand (CU[...]

In order of intr oduction: The Internal Coupling Facility (ICF) processor was intro- duced to help cut the cost of Coupling Facility functions by reducing the need for an external Coupling Facility . IBM System z Parallel Sysplex ® technology allows for greater scalability and availability by coupling mainframes together . Using Parallel Sysplex c[...]

point operations. This is expected to be particularly useful for the calculations involved in many fi nancial transactions. Decimal calculations are often used in fi nancial applica- tions and those done using other fl oating point facilities have typically been perfor med by software thr ough the use of libraries. With a hardwar e decimal fl o[...]

The z10 EC is also able to exploit numerous operating sys- tems concurrently on a single server , these include z/OS, z/VM, z/VSE, z/TPF , TPF and Linux for System z. These operating systems are designed to support existing appli- cation investments without anticipated change and help you realize the benefi ts of the z10 EC. System z10 – the new[...]

The System z10 EC is designed to provide balanced system perfor mance. From pr ocessor storage to the system’ s I/O and network channels, end-to-end bandwidth is provided and designed to deliver data wher e and when it is needed. The processor subsystem is comprised of one to four books connected via a point-to-point SMP network. The change to a [...]

The z10 EC has been designed to offer high performance and effi cient I/O structure. All z10 EC models ship with two frames: an A-Frame and a Z-Frame, which together sup- port the installation of up to three I/O cages. The z10 EC will continue to use the Cargo cage for its I/O, supporting up to 960 ESCON ® and 256 FICON channels on the Model E12 [...]

number will be reported by the Store System Information (STSI) instruction for software billing purposes only . There is no affi nity between the hardware model and the number of CPs. For example, it is possible to have a Model E26 which has 13 PUs characterized as CPs, so for software billing purposes, the STSI instruction would report 713. z10 E[...]

z10 EC P erf ormance The perfor mance design of the z/Architectur e can enable the server to support a new standard of perfor mance for applications through expanding upon a balanced system approach. As CMOS technology has been enhanced to support not only additional processing power , but also more PUs, the entir e server is modifi ed to support [...]

The z10 EC contains an I/O subsystem infrastructure which uses an I/O cage that provides 28 I/O slots and the ability to have one to three I/O cages delivering a total of 84 I/O slots.

FICON Support for Cascaded Directors Native FICON (FC) channels support cascaded directors. This support is for a single hop confi guration only . T wo- director cascading r equires a single vendor high integrity fabric. Directors must be fr om the same vendor since cas- caded architectur e implementations can be unique. This type of cascaded supp[...]

SCSI IPL now a base function The SCSI Initial Program Load (IPL) enablement featur e, fi rst introduced on z990 in October of 2003, is no longer requir ed. The function is now delivered as a part of the server Licensed Internal Code. SCSI IPL allows an IPL of an operating system from an FCP-attached SCSI disk. FCP Full fabric connectivity FCP full[...]
