Upgrade Path

Any z890 and any z9 BC model can be upgraded to a z10 BC. The z10 BC can also be upgraded to the high-end z10 EC Model E12. All of these upgrades are disruptive. Provided sufficient uncharacterized PUs are available, upgrades within the z10 BC (that is, by changing the capacity setting of CPs or by adding CPs, IFLs, zAAPs, zIIPs, ICFs, or SAPs) are nondisruptive.

Flowchart of z10 BC Upgradee Path

Technical Overview

The z10 BC further extends the leadership of System z by delivering expanded granularity and optimized scalability for growth, enriched virtualization technology for consolidation of distributed workloads, improved availability and security to help increase business resiliency, and just-in-time management of resources. The z10 BC is at the core of the enhanced System z platform and is the new face of System z.

In the area of server availability, enhancements have been engineered into the z10 BC to help eliminate unwanted down time. For example, preplanning requirements are minimized by delivering a fixed, reserved Hardware System Area (HSA) that enables dynamic creation of logical partitions, including logical channel subsystems, subchannel sets, and devices, using dynamic I/O without preplanning. Additionally, new capabilities are intended to allow you to dynamically change logical processor definitions and cryptographic co-processor definitions for a logical partition without requiring the logical partition to be deactivated and re-activated.

Further improvement to availability and flexibility is achieved with just-in-time deployment of capacity resources designed to dynamically change capacity when business requirements change. You are no longer limited by one offering configuration; instead one or more flexible configurations can be defined that can be used to solve multiple temporary situations. You can choose from multiple configurations and the configurations themselves are flexible so you can activate only what is needed from your defined configuration. Another significant change is the ability to add permanent capacity to the server when you are in a temporary state. These z10 BC enhancements are designed to allow you to take advantage of the technology helping to provide on-demand capacity more effectively. There are new terms governing System z Capacity Back Up (CBU) now available which allow customers to execute production workload on a CBU Upgrade during a CBU Test.

z10 BC 4-Core Chip Details

Schematic of a BC processor for the Z10 2098

Each processing unit (PU) chip is a four-core (quad-core) chip. Each of the four PU SCMs contains one PU chip. Three of the four cores (PUs) are active, making 12 PUs available on the z10 BC. Two of the 12 PUs are designated SAPs. The remaining 10 PUs may be characterized for customer use. No designated spares are available.

The L2 cache interface (L2 Intf) is shared by all four cores. The memory controller (MC) function controls access to memory. GX indicates the I/O bus controller that controls the interface to the host channel adapters accessing the I/O. The chip controls traffic between the microprocessors (cores), memory, I/O, and the L2 cache on the SC chips.

Each core on the chip runs at a cycle time of 0.286 nanoseconds (3.5 GHz). Each quad-core PU chip measures 21.97 x 21.17 mm, contains 6 km of wire, features 1188 signal and 8765 I/O connections, and has close to one billion (994 million) transistors.

Each PU has a 192 KB on-chip Level 1 cache (L1) that is split into a 64 KB L1 cache for instructions (I-cache) and a 128 KB L1 cache for data (D-cache). A second level on chip cache, the L1.5 cache, has a size of 3 MB per PU. The two levels on chip cache structure are necessary to optimize performance so that it is tuned to the high-frequency properties of each of the microprocessors (cores).
