  1. 1. What’s new in vSphere 5? Dan Brinkmann Solutions Architect at Lewan & Associates / Twitter: @dbrinkmann
  2. 2. ABOUT LEWAN• Customer-focused• Superb engineering talent• Cross technology offerings and options• Local talent and solutions, global strength• Process driven• Satisfaction guaranteed
  3. 3. 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
  4. 4. •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
  5. 5. • Convergence of the platform on ESXi• No more service console• Thin architecture• Smaller security footprint• Streamlined deployment and configuration• Simplified patching and updating model
  6. 6. • 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
  7. 7. 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
  8. 8. • 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
  9. 9. • 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
  10. 10. • 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
  11. 11. 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
  12. 12. • 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
  13. 13. • 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
  14. 14. • 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
  15. 15. • 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

  17. 17. • 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/
  18. 18. • 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
  19. 19. • 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
  20. 20. • 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
  21. 21. The vSphere WebClient runs within abrowserApplication Serverthat provides a Flex Clientscalable back end Back End The Query ServicevCenter in either Query obtains live data fromsingle or Service the core vCenterLinked mode Server processoperation vCenter
  22. 22. • Pre-packaged 64 bit app running on SLES 11• Optional support for remote Oracle DB• Embedded DB – 5 hosts/50VMs• External DC - <300 hosts/<3000VMs• No support for: Linked mode (requires ADAM), IPv6, vCenter Heartbeat, View Composer
  23. 23. • Dump Collector• Syslog server
  24. 24. • ESXi 3.5-4.1 T_KB_1_1&externalId=1021801• ESXi 5.0 T_KB_1_1&externalId=2004201• Syslog is what ―I‖ would use• Enabling syslog on ESXi 3.5 and 4.x d=1016621• Enabling syslog on ESXi 5.0 d=2003322
