  • esxcli is part of the ESXi Shell and part of the vCLI (vMA). That means that if you know esxcli on the ESXi Shell you will know it on the vMA or vCLI as well. PowerCLI on the other hand is something different and has a different purpose. Where esxcli is focused on configuration, troubleshooting etcPowerCLI is more focused on reporting and automation of configuration.
  • Storage DRS provides initial placement recommendations to datastores in a Storage DRS-enabled datastore cluster based on I/O and space capacity. During the provisioning of a virtual machine, a datastore cluster can be selected as the target destination for this virtual machine or virtual machine disk after which a recommendation for initial placement is done based on I/O and space capacity. As just mentioned Initial placement in a manual provisioning process has proven to be very complex in most environments and as such important provisioning factors like current I/O load or space utilization are often ignored. Storage DRS ensures initial placement recommendations are made in accordance with space constraints and with respect to the goals of space and I/O load balancing. Although people are really excited about automated load balancing… It is Initial Placement where most people will start off with and where most people will benefit from the most as it will reduce operational overhead associated with the provisioning of virtual machines.Can also schedule windows of high activity that it shouldn’t consider
  • VMFS-5 uses GPT instead of MBRVMFS-5 supports volumes up to 64TBThis includes Pass-through RDMs!VMFS-5 uses a Unified Blocksize –> 1MBVMFS-5 uses smaller Sub-Blocks~30.000 8KB blocks versus ~3000 64KB blocks with VMFS-3VMFS-5 has support for very small files (1KB)Non-disruptive upgrade from VMFS-3 to VMFS-5ATS locking enhancements (as part of VAAI)
  • Maintenance Mode / Standby Mode SupportvShield Agent VMs do not have to be evacuated for host to enter maintenance or standby modeWhen host enters maintenance/standby mode Agent VMs are powered off (after client VMs are evacuated)When host exits maintenance/standby mode Agent VMs are powered on (before client VMs are placed) Accounts for vShield Agent VM reservations (even when powered off)Waits for vShield Agent VMs to be powered on and ready before placing client VMsWill not try to migrate a vShield Agent VM (Agent VMs pinned to their host)

  • What’s new in vSphere 5? Dan Brinkmann Solutions Architect at Lewan & Associates / Twitter: @dbrinkmann
  • ABOUT LEWAN• Customer-focused• Superb engineering talent• Cross technology offerings and options• Local talent and solutions, global strength• Process driven• Satisfaction guaranteed
  • TECHNOLOGY SOLUTIONS Innovative and reliable IT solutions are in our DNA.Data Centerblade systems, stand-alone servers, server virtualization,range of operating systems, information lifecyclemanagement, SAN/NAS, storage management, data de-duplication, backup/recovery, archival, tape librariesNetworkvoice over IP, call center, routing/switching,telepresence/collaboration, wan acceleration, circuits,wireless, firewalls, VPN, access control, IDS/IPSApplication Delivery & Applicationsbusiness productivity applications, email, directory services,file/print, desktops, laptops, desktop virtualization, thinclients, mobility, anti-virus, anti-spam
  • •ESXi only • New VAAI primitives•ESXi CLI • vDS (span, LLDP, netflow)•New virtual machine format • NIOC enhancements•Auto deploy • Rewrite of HA•Storage DRS • vMotion / DRS enhancements•Profile-driven storage • ESXi firewall•VMFS 5 • vSphere web client•SIOC for NFS • vCenter linux appliance
  • • Convergence of the platform on ESXi• No more service console• Thin architecture• Smaller security footprint• Streamlined deployment and configuration• Simplified patching and updating model
  • • ESXi Shell • vMA • vCLI Appliance • Rebranded Tech Support Mode • PowerCLI • Local and remote (SSH) • Windows CLI Tool• vCLI • ‗esxcli‘ Command Set • Local and remote CLI • New and improved in 5.0 • ‗vicfg‘ Command Set • Remote CLI Only • Other Commands: • vmware-cmd, vmkfstools, etc. • vCLI available for Linux and Windows
  • Commands Run Local Run Remote ESX/ESXi 4.x ESXi 5.xesxcfg1 Yes No Yes Noesxcli2 Yes Yes No Yesvicfg3 No Yes Yes Yesvmware-cmd Yes Yes Yes Yesvmkfstools Yes Yes Yes YesPowerCLI No Yes Yes Yes1. ‗esxcfg‘ commands deprecated in 5.0 (replaced with esxcli)2. ‗esxcli‘ in 4.x is *not* backward compatible with 5.03. ‗vicfg‘ used for remote CLI only
  • • 3-D graphics for Windows Aero• USB 3.0 devices• Support for 32 vCPU and 1TB RAM• Multi-core vCPU support (licensing)• If using vCD check this link: d=displayKC&externalId=2005932• Upgrade VM tools then upgrade virtual hardware
  • • Works with Image Builder, vCenter Server, and Host Profiles• How it works: • PXE boot the server • ESXi image profile loaded into host memory via Auto Deploy Server • Configuration applied using Answer File / Host Profile • Host placed/connected in vCenter• Benefits • No boot disk • Quickly and easily deploy large numbers of ESXi hosts • Share a standard ESXi image across many hosts • Host image decoupled from the physical server• Recover host w/out recovering hardware or having to restore from backup
  • • Storage DRS provides the following: • Initial Placement of VMs and VMDKS based on available space and I/O capacity. • Load balancing between datastores in a datastore cluster via Storage vMotion based on storage space utilization. • Load balancing via Storage vMotion based on I/O metrics, i.e. latency.• Storage DRS also includes Affinity/Anti-Affinity Rules for VMs & VMDKs
  • Feature VMFS-3 VMFS-52TB+ VMFS Volumes Yes Yes (using extents)Support for 2TB+ Physical RDMs No YesUnified Block size (1MB) No YesAtomic Test & Set Enhancements No Yes(part of VAAI, locking mechanism)Sub-blocks for space efficiency 64KB (max ~3k) 8KB (max ~30k)Small file support No 1KB
  • • Adds support for NFS when using Storage I/O Control• Delivers same benefits now for NFS as existed in 4.1 for iSCISI and FC
  • • New primitives for VAAI NAS (Full File Clone and Reserve Space/thick VMDK) – note not shipped with ESXi 5.0• Write Same, ATS, and Full Copy now fully T10 compliant in ESXi 5.0• New VAAI UnMap – dead space reclamation, monitoring of space – Currently recommended to disable d=2007427
  • • LLDP – standard based vendor neutral discovery protocol• Netflow – collects IP traffic information, inter & intra VM• Port Mirror – (SPAN) overcomes limitation of promiscuous mode• NOIC at VM level – create VM resource groups
  • • Network I/O control is a traffic management feature of vSphere Distributed Switch (vDS)• In a consolidated IO (10 gig) deployments this feature allows customer to • Allocate Shares and Limits to different traffic types. • Provide Isolation • One traffic type should not dominate others • Guarantee Service Levels when different traffic types compete• Enhanced Network I/O Control — vSphere 5.0 builds on previous versions of Network I/O Control feature by providing • User-defined network resource pools • New Host Based Replication Traffic Type • QoS tagging

  • • Complete re-write of vSphere HA• Provides a foundation for increased scale and functionality• Eliminates common issues (DNS resolution)• Multiple Communication Paths• Can leverage storage as well as the mgmt network for communications A fun read availability-deepdiv/
  • • Every host runs a agent • Referred to as ‗FDM‘ or Fault Domain Manger • One of the agents within the cluster is chosen to assume the role of the Master • There is only one Master per cluster during normal operations • All other agents assume the role of Slaves• There is no more Primary/Secondary concept with vSphere HA
  • • Multi-NIC support – up to four 10Gbps or sixteen 1Gbps• Support for higher latency networks – up to ~10ms• DRS support Agent VMs and special handling of them
  • • Service oriented stateless firewall, restrict access to services based on IP/subnet• GUI for configuring firewall on ESXi 5.0 similar to classic ESX firewall• Host profile support for the ESXi 5.0 firewall• Upgrades from Classic ESX to ESXi 5.0 will have firewall settings preserved
