IBM Competitive Project Office IT Optimizations with Linux on System z - Best Fit Workloads Emily Farmer, IBM System z CPO Thursday, 15th May 2014 © 2013 IBM Corporation IBM Competitive Project Office What’s the right solution to address today’s IT challenges? Is this what your data center looks like?  Currently running lots of x86 or UNIX servers  Serious concerns about – High software licensing costs – Growth and scalability – High availability and security  Strategically committed to Linux and open source 2 © 2014 IBM Corporation IBM Competitive Project Office Is virtualization the answer? Today: WW server installed base (M) 90 42% 61% Growth in virtual servers per year Of all workloads are virtualized 70 2.5x More virtual servers than physical servers installed today 50 30 Data shows virtualized x86 platforms do not exhibit economies of scale 10 ’96 – – ’98 ’00 ’02 Physical Server Installed Base Virtual Server Installed Base ’04 ’06 ’08 ’10 ’12 2.4x Increase in cost per VM when going from a medium size deployment to a very large deployment 10x Increase in management costs for virtual servers from 2006 to 2013 Source: IDC; Solitaire Interglobal Ltd. 3 © 2014 IBM Corporation IBM Competitive Project Office The right solution: Linux on System z!  An excellent platform for large scale consolidation – Highly virtualized, and designed to run at very high CPU utilization rates  Fast, very high-capacity processors; extreme scalability and elasticity; ultimate levels of reliability, availability and security  Simplified administration, efficient IT operations  Low comparable total cost of ownership (TCO) 4 © 2014 IBM Corporation IBM Competitive Project Office Examples of workloads best suited to consolidate on Linux on System z 5 Mixed priority Consolidate large numbers of low utilization servers Transaction processing High I/O demand Applications critical to business revenue High availability and qualities of service Systems of engagement Co-location requirements © 2014 IBM Corporation IBM Competitive Project Office Statistical multiplexing models show how consolidating on a highly virtualized platform drives up CPU utilization Server utilization = 17% 6x Peak To Average  Consolidating variable workloads on a virtualized server reduces the overall variance  Consequently, larger servers with capacity to run more workloads can be driven to higher average utilization levels without violating service level agreements Server utilization = 70% A single variable workload requires a machine capacity of 6x average demand, yielding only 17% utilization For 97.7% SLA: 1.42x Peak To Average 144 workloads require a machine capacity only 1.42x average demand, driving utilization up to 70% 6 © 2014 IBM Corporation IBM Competitive Project Office System z virtualization is built-in to give the best workload isolation Work load … Work load Linux Linux Work load … Work load Linux Linux Work load Work load Work load Work load Linux Linux Linux Linux Virtual Linux CPUs z/VM CP1 z/VM CP2 CP3 CP4 … Physical Linux CPUs z/VM CP5 Virtualization hypervisor layer; up to 32 physical CPUs per VM; highly granular resource sharing (<1%) z/VM CP6 CP7 I/O and Network VM-to-VM communication via fast in-memory TCP/IP CP8 Shared-everything architecture Memory Hardware-enforced isolation: 10% of circuits support virtualization 7 © 2014 IBM Corporation IBM Competitive Project Office Virtualization: z/VM versus VMware System z and z/VM VMware vSphere Scalability 1,000‘s of virtual servers supported Practical use limits (vs. stated limits) Utilization Stable up to 100% utilization >80% not recommended Run multiple hypervisors Up to 60 copies of z/VM on system Only one hypervisor copy per server Memory over-commitment Yes Limited (memory ballooning) Hypervisor stack z/VM on z/VM supported No Physical upgrades Uninterrupted addition of processors and/or memory including capacity on demand No real (physical) capacity on demand (only virtual) HW sharing Run test and production on same HW Not recommended Security certification EAL5+ for LPAR, EAL4+ for z/VM EAL4+ Multi-level virtualization LPAR and z/VM Single level Live guest relocation z/VM V6.2 SSI/LGR vMotion GUI-based administration IBM Wave VMware VirtualCenter Operating system support Linux on System z (and z/OS, z/VSE, zTPF) Windows and Linux Oracle support Linux on System z (native and with z/VM virtualization) Not certified by Oracle (client must recreate problem w/o virtualization) 8 © 2014 IBM Corporation IBM Competitive Project Office System z demonstrates perfect workload management and very high utilization – x86 hypervisor does neither z/VM 10VM 32 Core CPU Usage With Physic zVM 10VM 32 Core % CPU Usage 100 90 % CPU Usage 70 60 50 40 30 20 10 0 5 1 hour 9 13 17 21 25 29 % 33CPU 37 41Usage 45 49 53FB 57 ESX ESX CPU 1 hourUsage Shared 1 5 9 13 17 21 25 29 33 37 41 45 49 53 57 Time (mins) 50 High priority workloads90.00 (blue) run at less high 80.00 utilization and degrade when low priority 70.00 workloads (maroon) 60.00 Us age - added FB Standalone50.00 40 x86 hypervisor 40.00 (gray) remains unused (22%) 10.00 90 % CPU Usage 70 60 P Time (mins) 0.00 55 50 45 40 35 1 hour 20 51 46 40 34 1 hour 29 23 17 12 6 0 15 10 5 10 20 0 D 30.00 Too much resource 20.00 30 0 % CPU Usage % CPU Usage 80 9 Time (mins) 100.00 100 30 1 25 % CPU Usage Usage % CPU 80 100.00 High priority workloads 90.00 (blue) run at very high utilization and do not 80.00 70.00 degrade 60.00 System z Usage - FB Standalone 50.00 Low priority 40.00 workloads (maroon) 30.00 consume all but 2% 20.00 of remaining 10.00 resources (gray) 0.00 © 2014 IBM Corporation IBM Competitive Project Office Result: System z easily manages mixed priority workloads at lower cost VMs Which platform provides the lowest TCA over 3 years?
