Try ‘prefixing’ the virtual I/O server command you’d like to run with /usr/ios/cli/ioscli Ex: # /usr/ios/cli/ioscli lsmap –vadapter vhost0 --OR-- # /usr/ios/cli/ioscli lsdev -virtual POWERVM Virtualization Capabilities Virtualization is the Fastest Growing Server Software Component in the Industry. PowerVM is the hardware and software that delivers industry-leading virtualization on IBM POWER processor-based servers for UNIX, i and Linux clients. Features of PowerVM virtualization software for Power™ Systems are  POWER Hypervisor: Support for virtualization and multiple operating environments.  Logical Partitioning: Flexibility to create either dedicated LPARs and/or Micro-partitions.  Shared Dedicated Capacity: Unused dedicated processor resource in a LPAR can be shared with other LPARs.  Dynamic Logical Partitioning (DLPAR): Dynamic resource movement between LPARs.  Multiple Shared Processor Pools: Cap processor resources for a group of partitions and share processing units between the LPARs in a group. Shared Processor Pools provide additional processing units on demand to micro-partitions dynamically.  PowerVM Active Memory™ Sharing (SOD – Statement of Direction): IBM intends to enhance PowerVM with Active Memory Sharing (ASM), an advanced memory virtualization technology. Active Memory Sharing will intelligently flow memory from one partition to another for increased utilization and flexibility of memory usage. This is planned to be available with PowerVM Enterprise Edition for AIX 6.1, Linux and i 6.1 partitions that use VIOS and shared processors on POWER6 processor-based systems.  Virtual I/O Server (VIOS): Virtualizes physical resources such as SCSI, Ethernet and SAN devices to share with multiple client LPARs running either AIX, Linux or IBM i OS.  Integrated Virtualization Manager (IVM): Simplifies partition management for entry systems. It is a browser based tool and provides the HMC functionality in a VIOS partition.  Lx86: Enables to run most x86 32 bit Linux binaries on Power Systems without recompilation. This is installed in a Linux partition on a Power Systems server.  Live Partition Mobility: Feature to move a AIX or Linux LPAR live from one POWER6 processor based server to another.  System Planning Tool: Simplifies the planning, ordering and deployment of Power servers with PowerVM. iSeries Redbooks Website PowerVM optimizes the computing resources by sharing them on Power Systems servers (Blades, Entry, Midrange and Enterprise http://www.redbooks.ibm.com/ class) and thus reduces TCO and improves ROI. Computing resources such as processors, memory (SOD), boot disks, network and SAN adapters can be shared by multiple LPARs in a consolidated environment.

  • 4. Power Architecture So how does IBM design those world- class leading Power Microprocessors? This is probably, the single most asked question I get on a day to day basis. IBM has enjoyed a large lead in microprocessor technology for many years thanks to our design teams. Let’s explore, briefly, how a Power processor is designed. Power design is a combined effort from design teams located in: Austin (TX), Burlington (VT), Raleigh (NC), Rochester (MN) and Böblingen (Germany). Our lead design team is located in Austin along with our main Power Systems Briefing Center. As a side, if you’ve never had a chance to visit an IBM Briefing Center, ask your IBM representative today; it’s an eye opening and very worthwhile experience. The first step in any design is to set the direction of the overall architecture of the specific chip being designed (i.e. Power5, Power6, etc). This is done as a collaboration between the various architects between sites. Microprocessor architects are the most experienced engineers within a design group. When setting the direction for a design, performance goals, reliability considerations and other factors are all considered. This design stage is called high level design (HLD). Before a processor design exits HLD, a performance model is made and the proposed design is “test driven” for performance. If the simulated performance is lacking then changes must be made in the design. When the proposed design meets all design criteria the real work begins. IBM usually splits its design teams into several smaller teams working on various projects. Some teams design game chips (Nintendo, Sony, Microsoft), others design high end chips (Power6, Power7) and still others design embedded processors (PowerPC 750, embedded processors used in NASA Mars mission, etc). There is some overlap between teams as some engineers may participate on more than one team. In addition to architects, within each team there are several roles, Logic Designers, Verification Engineers, Circuit Designers and Layout Technicians. Again, some designs may have multiple roles, but as a whole everyone on the team is very specialized. Let’s explore these roles: Logic designers develop the gate level logic of the processor. Before other engineers have any work to do, the logic design teams have to create a “first draft” of the processor. At this point, the verification team will compile the logic into a model of the processor which is used to run virtual compute test cycles. These test cycles run on the model are comprised of test programs and logic checkers that look for bugs in the compiled logic. When bugs are found the logic designer will investigate and fix the problem in an iterative fashion with the verification engineer. IBM runs several billion/trillion virtual clock cycles before any chip ever leaves our design labs. This gives IBM the utmost confidence that each chip is free of bugs. Once the logic design has begun, the circuit designers start their task. Their job is to translate the gate level logic into circuits used to do the work of the processor. As the logic designers change their logic the circuit designers must change their circuits in like fashion. Layout Technicians work with circuit designers. These skilled individuals carefully render each circuit into a manufacturable form. The layout of a modern VLSI CMOS chip is very much like a ridiculously large jigsaw puzzle. Each area of the silicon die (a die is a term referencing each processor on a wafer) must be carefully laid out in such a fashion as not to be too large or oddly shaped, adversely squeezing adjacent areas for space. In addition to all this design criteria, the design must be fast. Slow circuits are constantly analyzed and massaged for speed. After all, the chip is only as fast as its slowest circuit. This discussion only centers on the immediate design team of each microprocessor. It is important not to forget the teams of engineers outside of the immediate processor design that make each chip successful. Without these folks, even the best design will fall flat on its face. A design cycle for a high end processor usually lasts on average four years. During this time, the logic designers, verification engineers, circuits designers and layout techs go back and fourth with each other solving problems, working through bugs, and speeding up circuits. Once this process completes and the design is considered complete it is time for the RIT. RIT is an IBM term for “Release Interface Tape”, and antiquated term first used in the early days of semiconductor design. It specifically refers to writing the design to tape and shipping (carrying) it over to the manufacturing facility to start the fabrication process. RIT day in IBM is a big day. It’s the first time the design teams can take a break. After RIT, the teams will review their work for any patentable ideas. All ideas are submitted to IBM’s IP law department for patent consideration. Any unique and novel ideas are sent to the patent office in Washington DC. IBM engineers are famous for producing more patents each year than any other company in the world; many of these patents arise from IBM’s design activities. This is simply a brief overview of the IBM microprocessor design process. I could talk all day on this specific topic and often do if given the chance. If you’d like a more in depth view into this world I’d be happy to expand on any given topic. The next several articles will explore design elements in modern Power microprocessors.

  • 5. Power5/Power6 Firmware Updates Firmware Updates There are two reasons why you might want to update microcode: 1. IBM periodically updates microcode to add new function for your systems and adapters. For example, you might want to install new system flash microcode to add boot support for a boot device that was not available when your system was shipped; or you might want to update the microcode on a graphics adapter so you can attach a new display that was not previously supported. 2. You may want to update your microcode to fix a problem. Even IBM's rigorous test process does not always catch every problem. Whenever possible, we update the microcode to fix a problem. Using “Fix Central” to obtain the updates If you use IBM’s Fix Central website, you can not only obtain system microcode, but are given the following options: 1- All firmware components. Obtain system firmware, device firmware, and HMC updates. The power subsystem firmware will be included if applicable 2- System firmware. Obtain system firmware only. The power subsystem firmware will be included if applicable. 3- Device firmware. Obtain device firmware only. Available for adapters hard disks and media devices. 4- HMC Firmware. Obtain HMC Recovery images, service packs, and specific fixes. Fix Central also can help answer your questions – these links are available to help you decide what levels you should be running: • Frequently Asked Questions • Best practices • Subscription services • Quick link to description files • Quick link to latest fixes on CD-ROM • Fix Level Recommendation Tool • Supplemental Firmware • Firmware survey tools • Diagnostic CD-ROMs • Tape drive information • ISO / IEC compliant firmware • Power 5 HPSNM/IBMNM fixes and links • P5 and P6 HMC Network Install files Selected System Microcode Levels (as of March 24 th , 2009) 9119-FHA (595): EH340_039 9117-MMA(570): EM340_041 8203-E4A (520): EL340_039 Next Issue – Deciphering code levels, concurrent updates and deferred fixes.
