  2. Power 775 supercomputer Power 780 IBM IBM POWER Systems HPC Complete flexibility for workload deployment • Extensive range • Binary compatibility • Mainframe-inspired reliability • Hypervisor-based virtualisation • AIX, Linux and IBM i OS Enterprise Express 775 750 770/780 720/740 755 795 710/730 PS703/4 PS701/2 PS700

  3. IBM Power 795 The Benefits of Virtualisation • Shared processors • Increased server utilisation • Potential reduction in s/w costs • Shared adapters • Reduction in server costs • Reduction in infrastructure costs • Reduced environmental impact • Savings in heat, power and space • Rapid service provisioning • Reduction in time for procurement, provisioning and installation Shared Process Pool Shared Disk Adapters Shared Network Adapters Fewer switches and routers

  4. Power vs Linux and Intel • Individually, x86 systems are cheaper than POWER7 systems • But … multiplication of x86 servers inflates costs for • Software licensing • Support • Tools for systems management, security and clustering • SAN switches, Network routers • Energy and space • VMware, in practice, has limited effectiveness • Could you run your entire workload on one system if you had a sufficiently powerful server? • If not, why not? • PowerVM allows • Full virtualisation of all workloads • All workloads to coexist on a single server

  5. Linux – a matter of perception Adapted from “Does your OS Matter?” a survey of over 43,260 environments by Solitaire Interglobal Ltd. October 2011 *Calculated as the inverse of user complaints relative to the results for Windows

  6. AIX vs Linux - TCO and Business Agility • AIX users report • Lower staffing costs overall (due to tools, stability, etc.) • Lower datacentre costs (environmental, facility, etc.) • More highly-leveraged platforms • …and a definite agility advantage due to • Ability to easily shift resources to accommodate new implementations • Robust toolset for management • Speed of configuration with other system components, e.g. storage Adapted from “Does your OS Matter?” - Solitaire Interglobal Ltd. October 2011
