Licensing
" Free upgrade to v5.1 with valid support contract.
" No more vRAM entitlement licensing! " Licensed by physical CPU (as in the past).
" No price increases. (Some prices went down.)
" vSphere Standard Edition now includes: " Storage vMotion & Enhanced vMotion
" Fault Tolerance
" Hot Add
" vSphere Replication
p …existing Standard customers will receive these entitlements automatically!
" Acceleration Kit bundles are 6 CPU and come with vCenter Standard. " Essentials Plus Kit and all Acceleration Kits now
include Virtual Storage Appliance (VSA).

“Gotchas”
![Page 6: VMware vSphere 5.1 - Upgrade Tips & Top New Features](https://reader034.fdocuments.net/reader034/viewer/2022042607/55524edab4c905954f8b4f94/html5/thumbnails/6.jpg)
“Gotchas”
" VMware View 5.1.x is not currently supported with vSphere 5.1. " A vSphere 5.1 patch will be released this
month to fix this issue!
" SQL 2012 is not yet supported with any VMware products. " EMC PowerPath/VE requires a vSphere 5.1 hot-patch plus
PowerPath/VE patch to prevent Purple Screen of Death (KB #2034796). " Cisco Nexus 1000V requires new version. " Custom drivers (Ethernet, iSCSI, FC, FCoE) will need to be re-
installed. " Some server models are no longer supported by VMware. " Some storage array models are no longer supported by VMware. " Some databases are no longer supported by VMware. " Many third-party backup solutions do not support vSphere 5.1 yet.
![Page 7: VMware vSphere 5.1 - Upgrade Tips & Top New Features](https://reader034.fdocuments.net/reader034/viewer/2022042607/55524edab4c905954f8b4f94/html5/thumbnails/7.jpg)
“Gotchas”
" vCenter 5.1 is the first version of vCenter that cannot manage ESX(i) 3.x hosts. " OK to mix ESXi 4.x and ESXi 5.x hosts in the same cluster.
p Be careful with virtual hardware versions!
p VM Version 4 = ESXi 3.5+
p VM Version 7 = ESXi 4.x+
p VM Version 8 = ESXi 5.0+
p VM Version 9 = ESXi 5.1+
" VMware Tools 4.x and 5.x are fully compatible with 5.1. " VMware Tools 3.x and earlier are not supported with 5.1.
" VMFS-3 and VMFS-5 are both supported with 5.1. " VMFS-5 upgrades are non-disruptive.

“Gotchas”
" VMware Best Practice: If you have the luxury of doing so, create a brand new VMFS-5 datastore, use Storage vMotion to move VMs to it, then re-format old VMFS-3 datastore using VMFS-5.

Upgrade Tips
![Page 11: VMware vSphere 5.1 - Upgrade Tips & Top New Features](https://reader034.fdocuments.net/reader034/viewer/2022042607/55524edab4c905954f8b4f94/html5/thumbnails/11.jpg)
Upgrade Tips
" VMware Single Sign-On (SSO) is a brand new component that is required.
![Page 12: VMware vSphere 5.1 - Upgrade Tips & Top New Features](https://reader034.fdocuments.net/reader034/viewer/2022042607/55524edab4c905954f8b4f94/html5/thumbnails/12.jpg)
Upgrade Tips
" vCenter components require much more RAM than in the past. " vCenter + Single Sign On + Inventory Service installed together = 10 GB RAM minimum
p …plus SQL database = Add 2+ GB RAM p …plus Update Manager = Add 2+ GB RAM
" VMware Single Sign-On (SSO) is non-trivial* to set up. " vCenter database upgrade can cause database destruction*. " SRM upgrade can lead to services that won’t start*. " Some DBA/SQL experience required*, especially for SSO.
" Installing trusted certificates for VMware products is non-trivial*. " There are a few bugs* to be aware of.
" WWN display issues in Web Client (KB #2035448).
" Standalone vSphere Replication failover issue (KB #2035929).
* St. Croix Professional Services is highly recommended!!

Upgrade Tips
" High-level vSphere 5.1 upgrade strategy: 1. Verify compatibility of all components (software/hardware).
p Upgrade third-party software/hardware/firmware as required.
2. Upgrade VMware View to v5.1.1.
3. Upgrade vCloud Director to v5.1.
4. Upgrade vShield Manager to v5.1.
5. Upgrade vCenter to v5.1.
6. Upgrade SRM & vSphere Replication to v5.1.
7. Upgrade ESXi hosts to v5.1 (plus patch for VMware View compatibility).
8. Upgrade/rebuild datastores from VMFS-3 to VMFS-5.
9. Upgrade Virtual Distributed Switches to v5.1.
10. Upgrade VMware Tools to most current version.
11. Upgrade VM Hardware to v9.

New Web Interface
![Page 15: VMware vSphere 5.1 - Upgrade Tips & Top New Features](https://reader034.fdocuments.net/reader034/viewer/2022042607/55524edab4c905954f8b4f94/html5/thumbnails/15.jpg)
New Web Interface
" 5.1 marks the final release of the vSphere Client for Windows!
" New vSphere Web Client is only supported on specific browsers. " Internet Explorer 7, 8, 9
p Disable this: " Firefox 3.6 and later
p VERY SLOW " Google Chrome 14 and later
p VERY FAST!
" All browsers require Adobe Flash Player 11.1 or later.
![Page 16: VMware vSphere 5.1 - Upgrade Tips & Top New Features](https://reader034.fdocuments.net/reader034/viewer/2022042607/55524edab4c905954f8b4f94/html5/thumbnails/16.jpg)
New Web Interface
" Windows and Linux are supported today. " Client Integration Plug-In is required for:
p VM Remote Console (but you should use RDP instead!) p Datastore File Upload/Download
" Mac OS X will be supported in the future p Works great today on Google Chrome for Mac
p …but there is no Client Integration Plug-In
" Many vCenter plug-ins do not work in the Web Client (today): " VMware Update Manager " VMware Site Recovery Manager " Many third-party plug-ins

Enhanced vMotion*
* Also commonly referred to as: • Unified vMotion • X-vMotion • vSphere 5.1 vMotion • Shared Nothing vMotion • vMotion + Storage vMotion
![Page 19: VMware vSphere 5.1 - Upgrade Tips & Top New Features](https://reader034.fdocuments.net/reader034/viewer/2022042607/55524edab4c905954f8b4f94/html5/thumbnails/19.jpg)
Enhanced vMotion
" Combination of vMotion and Storage vMotion.
" Migrate VMs live between hosts/clusters without shared storage.
" Supported on vSphere Standard* and above.
* Frank Denneman’s blog indicates support for Essentials Plus customers, but current GUI blocks Enhanced vMotion in Essentials Plus.
![Page 20: VMware vSphere 5.1 - Upgrade Tips & Top New Features](https://reader034.fdocuments.net/reader034/viewer/2022042607/55524edab4c905954f8b4f94/html5/thumbnails/20.jpg)
Enhanced vMotion
" Can only be performed in the new Web Client.
" Hosts must be managed by same vCenter.
" Hosts must be part of same Datacenter.
" Hosts must be on the same Layer 2 network (and same vSwitch if using Virtual Distributed Switch).
" Uses vMotion (LAN) interface for “shared nothing” data transfer; uses storage fabric for data transfer if destination is on shared storage.
" Maximum of 2 concurrent Storage vMotions (including Enhanced vMotions) per host.
" DRS and SDRS do not use Enhanced vMotion technology at all, and will not make any recommendations for Enhanced vMotion migrations.
" Remember that HA still requires shared storage!
" For a true HA/DRS-enabled cluster, you still need shared storage.
![Page 21: VMware vSphere 5.1 - Upgrade Tips & Top New Features](https://reader034.fdocuments.net/reader034/viewer/2022042607/55524edab4c905954f8b4f94/html5/thumbnails/21.jpg)
Enhanced vMotion
" Storage vMotion and Enhanced vMotion support parallel disk copies (up to 4 VMDK’s simultaneously).
" Only applies to disk copies between distinct datastores.
![Page 22: VMware vSphere 5.1 - Upgrade Tips & Top New Features](https://reader034.fdocuments.net/reader034/viewer/2022042607/55524edab4c905954f8b4f94/html5/thumbnails/22.jpg)

vSphere Replication 5.1
" Now included in all editions of vSphere 5.1 from Essentials Plus and above at no additional cost.
" Baseline replicas can be “seeded” at remote site easily.
" Up to 500 VMs can be replicated.
" RPO can be between 15 minutes and 24 hours.
" Can be used for local replication within the same vCenter.
" Leverages Microsoft VSS to quiesce the file system as well as VSS-aware applications, such as SQL and Exchange.
" Only block-level changes are transferred across the network.

Site Recovery Manager 5.1
" SRM now supports vSphere Essentials Plus.
" SRM now supports “Reprotect” with vSphere Replication.
" Storage DRS and Storage vMotion are now supported with SRM.
" SRM client is currently only available from the “legacy” Windows vCenter Client. " …except for vSphere Replication, which is managed from
the Web Client. " …but VMware promises to release a complete SRM Web Client
within 90 days of GA.
p i.e. December 2012?

![Page 29: VMware vSphere 5.1 - Upgrade Tips & Top New Features](https://reader034.fdocuments.net/reader034/viewer/2022042607/55524edab4c905954f8b4f94/html5/thumbnails/29.jpg)
Networking
" Virtual Distributed Switch Health Check detects common problems:
" VLAN assignment (requires 2+ pNICs)
" MTU mis-match (requires 2+ pNICs)
" NIC teaming/load balancing mis-match (requires 2+ pNICs & 2 hosts)
![Page 30: VMware vSphere 5.1 - Upgrade Tips & Top New Features](https://reader034.fdocuments.net/reader034/viewer/2022042607/55524edab4c905954f8b4f94/html5/thumbnails/30.jpg)
Networking
" Automatic Network Rollback helps recover from typical configuration mistakes on management interfaces (i.e. “user error”): " VLAN mismatches
" IP address conflicts
" MTU size conflicts
" NIC teaming/load balancing conflicts
" NIC speed/duplex mismatches
" DNS and routing mismatches
" Available on Virtual Distributed Switch (VDS) as well as Virtual Standard Switch (VSS)
" Now you can “safely” run management traffic through your VDS!
" Enabled by default in v5.1.
![Page 31: VMware vSphere 5.1 - Upgrade Tips & Top New Features](https://reader034.fdocuments.net/reader034/viewer/2022042607/55524edab4c905954f8b4f94/html5/thumbnails/31.jpg)

Networking
" BPDU Filter for Standard and Distributed vSwitch:
" Not the same as BPDU Guard.
p Can still allow Layer 2 loops.
" Will prevent entire ESXi host from having ports blocked by upstream switch’s BPDU Guard feature.
" Not enabled by default; you must enable it manually:
