Orange County Convention Center Orlando, Florida | May 15-18, 2011 why customers choose Cisco for SAP Dr. Michael Missbach Cisco SAP Competence Center About the speaker IT Superintendent Europe ALCOA Project Manager General Electric Senior Consultant HP SAP Competence Center Manager Cisco SAP Competence Center in Walldorf Real Experience. Real Advantage. State of the art multi core technology enables higher server utilization 1 PwK = n [∑- (n × R)k k=Φ k! ]/[ (n × R)n n! ] ×(1- R)+R Markov Chain Theory: likelihood that a transaction have to wait a given time in relation to the numbers of cores average load a system should not exceed in relation of the number of CPU’s for a given response time distribution: Number CPU 1 2 3 4 6 8 10 12 16 Real Experience. Real Advantage. max CPU for 2 sec 22% 46% 59% 67% 76% 81% 84% 86% 89% max CPU for 1 sec 15% 36% 48% 56% 66% 72% 76% 79% 83% But most servers run below 20% utilization because of insufficient memory Increased memory enables more guests Standard memory technology 96 GB for standard 2 CPU blades Cisco extended memory technology 1 TB on 2-way server Study demonstrates 71% scaling due to Cisco extended memory technology Compute resources fully utilized Less cores – less VMware licenses Standard technology 7 VMs for 96GB 196 GB Extended memory technology 12 VMs Benchmark environment (300 User per VM, resp time < 1 sec) Example Server config with VMs provisioned to maximize memory capacity (ie 30 VMs) Note this config is only possible in case the client subscribes to a 300 user VM but utilizes much lower than the capacity planned (Eg. 100 users) Realistic environment: 30+ VMs on a 2 way system Real Experience. Real Advantage. Cisco removing the I/O bottleneck enables virtualization of large SAP databases Software based Virtual Switching Hypervisor needs to switch LAN and storage I/O Consumes additional CPU cycles Adds significant latency to I/O Practically prohibitive for virtualization of larger databases (SAP note: if you run into perfromace trouble with virtualization: move to bare iron. If trouble disappears, this was the right solution) VM VM VM VM Hypervisor Soft Switch standard VIC Cisco solution:VM-FEX Hypervisor vSwitch removed Massive I/O throughput improvements, less latency CPU cycle relive, less interrupts VM VM VM VM VM-FEX (Hypervisor pass through mode) Each VM gets a dedicated PCI device (up to 56) Each VM gets a virtual port on physical switch 10GbE/FCoE end-to-end QoS per VM down to storage 10GbE/FCoE 0 1 2 3 ………… 56 Cisco VIC running VM-FEX mode provides ASIC based low latency VM switch Real Experience. Real Advantage. Proven by benchmark Real Experience. Real Advantage. Proven by reality POC for large automotive customer by SAP CoE Single Cisco B200 2-way blade ECC 6.0 with RedHat on VMware Customer specific SD scenario and real data Requested 1200 users with average sub-second response times easily reached Trial to find the limits of the B200 Load generator ran out of steam Parts of the load generator moved dynamically to the blade Single B200 blade was still able to support 2000+ SAPGUI users with <60% CPU load in one virtual machine together with the load generator in 2 others Result: Overall targets have been overachieved Real Experience. Real Advantage. Typical Blade architectures - plenty of components to configure, managed and can fail Mgmt Server Redundant LAN Switches per enclosure Redundant SAN Switches per enclosure Enclosure management system (typically a SPoF) Redundant top of the rack / end of the row LAN Switches Redundant top of the rack / end of the row LAN Switches Redundant System management servers Complex to configure and to extend without (changing FC Zoning …..) Complex application specific cluster solution SAP Licence keys still bound to physical hardware Real Experience. Real Advantage. Cisco UCS reduce complexity what's not there must not be managed and can’t fail Cisco UCS architecture eliminates a complete layer Integrated LAN/SAN ports extended down to the enclosure – “one hop” switching Centralized redundant Switches manage the whole row Service Profiles enables full SAP System mobility no need to generate new SAP license keys after move no need for cluster software to grant HW availability Real Experience. Real Advantage. SAP on UCS - Customer Examples SAP ESS, MSS, E-Recruiting Business Objects, Virsa, Solution Manager Challenge DC running out of power & cooling fifteen cables per server Cisco Solution 26 UCS B250 with 192GB memory (Large fraction running SAP) replace 180 Dell and other servers Ability to Vmotion SAP with 16-32 GB memoryVMs fast over 10GE enables new types of management flexibility savings in power & cooling $15K cost reduction per server by removing complex web of cables 3000 Users / ~3TB SAP ECC 6.0 Unicode, BW XI (B2B/A2A), SAP PLM/Risk/Compliance, SAP Product Enablement Challenge Reduce TCO Cisco Solution migration from HP-UX on Superdome to UCS Challenge Legacy system required fifteen cables for each new server Cut deployment time for ESX Cisco Solution UCS with Windows on VMware ESX Shifting 90% of all Windows apps onto 75 VMs VM deployment reduced from 1-2 weeks to 30 min SAP Americas chose Cisco UCS as their Server virtualization standard for their DC running internal IT including SAP ERP and CRM Real Experience. Real Advantage. Unified Fabric Dramatic reduction in network adapters, blade-server switches, and cabling by passing all network traffic to parent fabric. Embedded Multi-Role Management Embedded in the fabric interconnects, managing all aspects of system configuration and operation. Cisco Extended Memory Technology Provides more than double the amount of memory than traditional 2-socket servers, maximizing performance and capacity for demanding virtualization and large-dataset workloads. VM-FEX Virtualization Support Gives network links connected to virtual machines the same status as physical links. Now virtual links can be centrally configured and managed without the complexity of traditional systems that interpose multiple switching layers in virtualized environments Dynamic Provisioning - Service Profiles UCS Manager implements a policy-based management focused on service profiles and templates and stateless compute blades Real Experience. Real Advantage. Summary: what customer like on UCS • ASIC based low latency switch replaces Hypervisor soft switch • up to 56 virtual NICs and HBAs per blade dynamically configurable • Collapses virtual and physical switching layers • Massive I/O throughput improvements (less latency, interrupts, CPU cycles) • Enables end-to-end QoS per VM down to storage • Enables virtualization of large SAP databases • No need to change the FC Zoning anymore– just connect fabric interconnect once to the existing infrastructure and add blades as you go • 15 minutes to add Chassis or Blades (UCSM auto-discovery) • 10 minutes to configure up to 56 virtual NICs and HBAs per blade • 10 minutes to add an ESX server • 10 minutes to add an SAP App server • Application mobility through Service Profiles – no need to generate new SAP license keys after system move – no need for cluster software to grant HW availability Real Experience. Real Advantage.
