VMware vSphere Nth Generation Computing
VMware vSphere architecture VMware vSphere
VMware VMotion • What is it? • Live migration of virtual machines from one host to another with no service interruption • Impact • Zero downtime • Continuous service availability • 8 – 5 maintenance • Complete transaction integrity • Supported on Fibre Channel, iSCSI SAN and NAS
Distributed Resource Scheduler Creating a Unified Compute Resource • Automates initial virtual machine placement • Uses VMotion to continuously optimize based on current workload • Reacts to adding or removing hosts from the cluster
Distributed Power Management • Dynamically reduce your power footprint • During non-peak hours, consolidate VMs onto fewer hosts • Place unnecessary hosts in standby mode • When load increases, bring additional hosts out of standby • vSphere supports WOL and new wake technologies (iLO, IPMI)
VMware High Availability VMware vSphere VMware vSphere VMware vSphere VMware HA enables cost-effective high availability for all applications • What is it? • Automatic restart of virtual machines in case of server failure • HA Impact • Cost effective high availability for all applications • No need for dedicated stand-by hardware • None of the cost and complexity of clustering
VMware ESXi Next generation, thin hypervisor integrated in server systems • Thin architecture • Unparalleled security and reliability • Fits on a 1GB USB Flash Drive • Only OS-independent design focused on virtualization • Integrated in server systems • Easiest way to deploy and manage virtualization • Hardware is certified and ready-to-run • Intuitive start up experience that dramatically reduces deployment time • Optimized for central management
Why you should be using ESXi • Higher Density • Lower Cost • Less Complexity • Future of development • “In the future, ESXi’s superior architecture will be the exclusive focus of VMware’s development efforts.” • ESXi Team Blog “ESXi Chronicles”, June 1st 2009 • “Due to the superior nature of ESXi, VMware will discontinue the classic Service Console-based ESX in the near future” • Session abstract for VMworld 2009 TA4060, “The Path to COS-less ESX: Migrating Server Operations from ESX to ESXi” • So don’t bet on there being a version 5 of ESX “Classic”
VMware Update Manager • Automates patch management for ESX Server hosts and select Microsoft and RHEL virtual machines • Scans and remedies online as well as offline virtual machines and online ESX Server hosts • Snapshots virtual machines prior to patching and allows rollback to snapshot • Eliminates manual tracking of patch levels of ESX Server hosts and virtual machines • Automates enforcement of patch standards • Reduces risk through snapshots and offline virtual machine patching
Zero-Downtime Host Patching • Update Manager patches entire DRS clusters • Each host in the cluster enters DRS maintenance mode, one at a time • VMs are migrated off, host is patched & rebooted if required • VMs are migrated back on • Next host is selected Update Manager server VMotion VMotion • Automates patching of large number of hosts with zero downtime to virtual machines
Update Manager Improvements • Upgrades as well as Patching • Update Manager is preferred upgrade tool for VI35->VS40 • VM Upgrades (VMware Tools, VM Hardware Version) • Staging Patches • Now you can pre-load patches onto your hosts before your maintenance window to reduce patch time. • Shared Repositories • Multiple Update Manager servers can share a single patch repository.
Storage VMotion • Storage independent migration of virtual machine disks • Zero downtime to virtual machines • LUN independent • Supported for Fibre Channel & iSCSI SANs • Minimizes planned downtime due to storage • Complete planned downtime management solution across servers and storage with VMotion and Storage VMotion
Storage VMotion Improvements • Much faster thanks to block-change tracking • Virtual Hardware version 7 VMs track changed blocks, making SVMotion deltas quicker • Doesn’t require double resources • No longer requires a “self-vMotion” meaning your VM takes up double the CPU and RAM during SVMotion • As a result, doesn’t need VMotion to be enabled on host • Can move between all supported storage types • FC, iSCSI, NFS • Switch from Full- to Thin-Provisioned during SVMotion • GUI SUPPORT!
VMware Fault Tolerance App App App App App App App OS OS OS OS OS OS OS • Single identical VMs running in lockstep on separate hosts • Zero downtime, zero data loss failover for all virtual machines in case of hardware failures • Integrated with VMware HA/DRS X X HA HA FT VMware ESX VMware ESX • Zero downtime, zero data loss • No complex clustering or specialized hardware required • Single common mechanism for all applications and OS-es
Distributed vSwitches • New Distributed Virtual Switch technology allows one vitual switch to manage your entire virtual datacenter. • Use the built-in VMware Distributed vSwitch or replace it with a Nexus 1000V virtual switch.
Host Profiles • Configure your ESX server once, then replicate its configuration to other servers. • Automatically configure new cluster members with a base config. • Use for compliance – easily identify misconfigurations
Thin Provisioning • Provision your VMs with disks that grow as needed. • Doesn’t require array support. • New alarming and reporting capabilities keep you out of trouble. • If you run out of space, VMFS now supports volume grow.
vShield Zones • Create VM-aware firewalls and trust zones, all within your Virtual Infrastructure • Base your trust zones on existing containers like hosts, vSwitches, or folders. • Runs as a virtual appliance.
vSphere Data Recovery • vSphere Data Recovery integrates disk-to-disk backup into the vSphere Client. Includes Deduplication!
vSphere Data Recovery • Full VM restore is as easy as rolling back to a snapshot. • File level restore is as easy as copying files from a mounted drive letter.
Bigger VMs, Bigger Hosts • New Host Maximums: • 64 logical CPUs, 1TB Memory, 320 VMs, 350K IOPS • “Logical CPU” is Sockets x Cores x Threads • New Virtual Machine Maximums: • 8 vCPUs, 255GB Memory, Faster SCSI and NIC adapters • Paravirtualized SCSI adapter provides better storage I/O rates • VMXNET3 NIC supports all kinds of offload, including Receive Side Scaling in Windows 2008
Performance is Key • In an 8vCPU VM, OLTP throughput is 86% of native • VMware whitepaper “Performance and Scalability of Microsoft SQL Server on VMware vSphere 4” • World-record 50,166 score on SPECweb2005 • 14% improvement over previous record on VI3 • SAP workloads handle 95% users of native • VMware whitepaper “Virtualized SAP Performance with VMware vSphere 4” • SPECjvm2008 ops/m is 94% of native • Accommodate 8000 Heavy Users in Exchange 2007 on an 8 core server (2x of native!) • VMware whitepaper “Microsoft Exchange Server 2007 Performance on VMware vSphere 4”

But what about support? • Microsoft has developed the Server Virtualization Validation Program (SVVP) • These Hypervisors receive support equal to that of physical hardware • VMware ESX 3.5 was the first hypervisor on this list! • Windows 2003, 2008, and 41 Microsoft applications are supported. • vSphere already supported!
