VMware ESX: Even More Reliable than a Mainframe! eternal validation of VMware product reliability

Customers Count on VMware ESX Reliability VMware ESX: #1 in Reliability Large pharmaceutical customer: Over four years of VMware ESX uptime! Companies Trust Their Production Servers to Run on VMware

Hypervisor Architectures Do Matter VMware Architecture True thin hypervisor No general-purpose OS Direct driver model = I/O scaling Drivers optimized for VMs Page Sharing = Greater Density Hypervisor owns the resources MSFT / Xen Architecture Large general purpose OS in management partition Indirect driver model Generic drivers in mgmt partition I/O bottlenecks under load Mgmt OS & drivers are single point of failure

Driver Model Impact on Scalability Heterogeneous Workload: VMmark Comparison Hyper-V out-of-bo Benchmark Score (bigger is better) 7 6 5 4 3 2 Hyper-V with tuned storage ESX 3.5 VMware ESX Near linear scaling MS Hyper-V Clear drop-off as load increases 1 0 1 2 3 4 Number of Tiles ESX outperforms Hyper-V on VMmark (heterogeneous workloads) by up to 93% Demonstrates more efficient ESX scheduler and direct driver model

Size Does Matter Windows Server 2008 R2 RC Server 70 MB Citri Core XenServer with Hyper-V v4 VMware ESXi 4.0 1.8 3.6 GB Hyper-V Server 2008 R2 RC is even bigger at 4.4 GB

Downside: Windows Updates Affect Hyper-V Datacenter downtime due to Microsoft Patch Tuesdays In most Patch Tuesdays since MS Hyper-V was released, patches consisted of Important updates to Server Core that were: 1. UNRELATED to a Hyper-V install, 2. Required a REBOOT of the host, 3. Caused VM DOWNTIME since Hyper-V doesn t support live migration. 7/8/08 8/12/08 9/10/08 10/21/08 11/18/08 12/9/08 1/13/09 Misc Number of Patches for Server Core 2 3 4 5 2 1 1 5 % Patches Related to Hyper-V 0% 0% 25% 40% 0% 0% 0% 20% Reboot Required YES YES YES YES YES YES YES YES Clear eample of the negative impact of virtualization as part of a general purpose operating system

Summary: Built on a Reliable Foundation Comparing ESXi with Microsoft Hyper-V Small Disk Footprint OS Independence Hardened Drivers ESX/ESXi 3.5 Hyper-V 1.0 32MB disk footprint (VMware ESXi) No console OS (VMware ESXi) Optimized with hardware vendors 2.6GB with mandatory Server Core installation Relies on Windows 2008 Generic Windows drivers Advanced Memory Management Ability to reclaim unused memory, de-duplicate memory pages No ability to reclaim unused physical memory Advanced Storage Management VMware vstorage VMFS Lacks an integrated clustered file system High I/O Scalability Direct driver model I/O bottlenecks in parent OS Host Resource Management Network traffic shaping, Storage I/O priorities, per-vm resource shares Lacks similar capabilities Performance Enhancements AMD RVI, large memory pages, universal 4-way vsmp, VMI paravirtualization No AMD-RVI, no large memory pages, 4-ways vsmp on Windows 2008 VMs only Virtual Security Technology VMware VMsafe Security API Nothing comparable

Limitations of Managing ESX with Microsoft SCVMM Microsoft hopes that its customers, already implementing the competing hypervisor [ESX], stop using VirtualCenter and turn to SCVMM 2008 for any task. Unfortunately this goal seems hard to achieve considering some limitations that plague this first attempt. Virtualization.info, 2008 No VirtualCenter (VC) Network Labels seen No VM CPU reservations or limits can be set No VM memory resource allocations No disk resource allocations No processor affinity settings Can t install or upgrade VMware tools No VMware tools power control settings No where to see the location of a VM s.vm file No host maintenance mode Can t configure HA, DRS, DPM, Update Manager Can t set swapfile locations No visibility into Guided Consolidation No performance monitoring\reporting for ESX hosts & VMs No VC tasks, events, and alarms seen No configuration settings for VC permissions\roles Can t clone to template Can t create resource pools.

VMware: Proven Solution, Unrivaled Customer Success 130,000+ VMware customers 100% of Fortune 100 98% of Fortune 1000 94% use VMware in production 70% use VMotion in production 65% VMware as the default/ most new production servers The World s Most Successful Companies Run VMware (hundreds of customer stories on www.vmware.com)

But what about cost? VMware solutions are a lower cost per application than other so-called free virtualization offerings.

What is Cost per Application VM density is critical in a virtual environment Physical World Virtual World 1:1 relationship between applications and hardware Relevant cost metric = upfront licensing Many:1 relationship between applications and hardware Relevant cost metric = cost/application

VMware Density Advantage Why VMware s superior technology makes it a less epensive solution Memory Oversubscription More efficient use of physical RAM by reclaiming unused physical memory and consolidating identical memory pages among VMs on a host. Direct Driver Model VMware ESX can achieve very high I/O throughput and can handle the I/O requirements for more VMs simultaneously requesting hardware resources. Support for Large Memory Pages and Nested Page Tables Optimize memory access and can provide substantial performance benefits for mission critical, memory-intensive applications, can reduce CPU resource consumption by up to 15%. DRS with Resource Pools Dynamically load balance VMs across a cluster so applications get required resources when they need them -a safety net that lets administrators run individual servers at higher utilization levels while meeting service level agreements. High Performance Gang Scheduler Can account for CPU and I/O needs of virtual machines by dynamically allocating more resources and larger processor timeslices to VMs.
