Chapter 1.
The innovative IBM Power 570 mid-range server with POWER6 and available POWER6+ f
processor cards delivers outstanding price/performance, mainframe-inspired reliability and
availability features, flexible capacity upgrades, and innovative virtualization technologies to
enable management of growth, complexity, and risk.
The Power 570 leverages your exisiting investments by supporting AIX, IBM i, and Linux for
Power, and x86 Linux applications on a single server. It is available in 2-, 4-, 8-, 12-, and
16-core and 32-core configurations. As with the p5 570, the POWER6-based 570s modular
symmetric multiprocessor (SMP) architecture is constructed using 4U (EIA units), 4-core or
8-core building block modules (also referred to as nodes, or CECs). Each of these nodes
supports four POWER6 3.5, 4.2 or 4.7 GHz dual-core processors, and new POWER6 4.2
GHz dual-core processors, or POWER6+ 4.4, and 5.0 GHz four-core processors along with
cache, memory, media, disks, I/O adapters, and power and cooling to create a balanced,
extremely high-performance rack-mount system.
This design allows up to four modules to be configured in a 19-inch rack as a single SMP
server, allowing clients to start with what they need and grow by adding additional building
blocks. A fully configured 570 server may consist of 32 processor cores, 768 GB of DDR2
memory, four media bays, integrated ports for attaching communications devices, 24 mixed
PCI-X and PCI Express adapter slots, and 24 internal SAS (Serial Attached SCSI) drives
accommodating up to 7.2 TB of internal disk storage.
The 64-bit POWER6 processors in this server are integrated into a dual-core single chip
module and a dual-core dual chip module, with 32 MB of L3 cache, 8 MB of L2 cache, and 12
DDR2 memory DIMM slots. The unique DDR2 memory uses a new memory architecture to
provide greater bandwidth and capacity. This enables operating at a higher data rate for large
memory configurations. Each new processor card can support up to 12 DDR2 DIMMs
running at speeds of up to 667 MHz.
As with the POWER5™ processor, simultaneous miltithreading enabling two threads to be
executed at the same time on a single processor core is a standard feature of POWER6
technology. Introduced with the POWER6 processor design is hardware decimal
floating-point support improving the performance of the basic mathematical calculations of
financial transactions that occur regularly on today's business computers. The POWER6
