Agenda/Myths
1) vMotion is only possible with shared storage.
2) You have to run Windows to manage vSphere.
3) You need Site Recovery Manager to protect your virtual machines from a complete site loss.
4) Due to VMFS, the maximum number of host in a cluster with linked clones is 8.
5) It’s not possible to backup or restore a Distributed vSwitch configuration.
vMotion is only possible with shared storage
Myth 1
New Enhanced vMotion
• Combine vMotion and Storage vMotion.
• Migrate between hosts/clusters without shared storage.
New Enhanced vMotion
• Enhanced vMotion allows you to combine a vMotion and Storage vMotion into a single operation.
• Effectively enabling a “shared nothing” vMotion.
New Enhanced vMotion
• Use cases can be found in large datacenters and SMB markets; Cross host and datastore vMotion allows VM migration between clusters in a large datacenters, which may not have a common set of datastores between them.
Myth Busted
• Two Enhanced vMotion + 6 vMotions at the same time or two Enhanced vMotions + Zero svMotions at the same time.
• DRS or sDRS don’t use Enhanced vMotion technology.
• Leverage the advantages of vMotion (zero-downtime migration) without the need for shared storage configurations.
You need Windows to manage vSphere
Myth 2
The VMware vSphere Web Client
• In vSphere 5.1, the VMware vSphere Web Client is the new primary point for vSphere management.
• It has several advantages over the previous Microsoft Windows–based VMware vSphere Client.
The VMware vSphere Web Client Object Navigator
Sidebar Extension
Create custom actions Inventory Objects Tabs
Add right-click extensions
Portlets
The VMware vSphere Web Client
• In the Web Client, vSphere introduces a new feature called “Work in Progress,” with which the user can pause a current task to work on another task in the UI and then later resume the original task at the point it was interrupted.
Myth Busted
• All new vSphere 5.1 features are only available from the Web Client.
• With the improvements added to VMware vSphere 5.1, the VMware vCenter Server architecture, VMware vCenter Single Sign-On, VMware vCenter Inventory Service and the VMware vSphere Web Client, VMware has released a formidable collection of tools for the administrator of a virtualized environment.
You need SRM to protect your virtual machines from a complete site loss
MYTH 3
vSphere Replication
• vSphere Replication is now a feature of the vSphere platform.
• It copies a virtual machine to another location, within or between clusters, and makes that copy available for restoration through the VMware vCenter Server Web Client.
vSphere Replication
• vSphere Replication is inherently a lightweight replication protocol.
• By replicating only changed blocks on an on-going basis network bandwidth can be saved and commit times for data are minimized.
How to configure vSphere Replication?
• vSphere Replication is a feature of the vSphere platform.
• It copies a virtual machine to another location, within or between clusters, and makes that copy available for restoration through the VMware vCenter Server Web Client.
Configure the recovery point objective
• Part of this process is to select a recovery point objective (RPO), which provides information to vSphere Replication regarding an age limit for the copy of the virtual machine.
• It then attempts to replicate data to meet the RPO at all times.
• Ensuring that the virtual machine data is never older than the defined policy for each virtual machine configured for replication.
Recovering a Virtual Machine • Recovery of a virtual machine
might be necessary for a number of reasons, ranging from testing, impending outages or even recovery from a disaster.
• vSphere Replication is designed to give administrators the ability to manually recover an individual machine with a small number of clicks in the vSphere Web Client.
Myth Busted
• vSphere Replication enables efficient array-agnostic replication of virtual machine data over the LAN or WAN.
• vSphere Replication simplifies management enabling replication at the virtual machine level and enables RPOs as low as 15 minutes.
• Make vSphere Replication a part of your vSphere 5.1 deployment and improve your virtual machine availability without introducing risk.
Due to VMFS the maximum number of host in a cluster is 8
Myth 4
VMware vSphere VMFS-5 file-sharing enhancements
• Prior to vSphere 5.1, the maximum number of hosts that could share a read-only file on a Virtual Machine File System (VMFS) was 8.
• This is a limiting factor for virtual desktop infrastructure (VDI) deployments using View.
• Because the maximum number of hosts in a cluster that could share the same desktop base disk image file was also 8.
• It is also a limiting factor for deployments of vCloud Director, which uses linked clones for the fast provisioning of VMware vCloud Director vApps.
VMware vSphere VMFS-5 file-sharing enhancements
• In vSphere 5.1, the maximum number of hosts that can share a read-only file on a VMFS is increased to 32.
• This means that linked clones deployed from a base image now can be hosted on any one of the 32 hosts sharing the datastore.
• This provides significant scalability for both View and vCloud Director. This feature applies only to hosts running vSphere 5.1 and higher on VMFS-5.
Myth Busted
• With vSphere 5.1 you’re able to Increase the file share limit on VMFS-5 from 8 to 32, making VMFS as scalable a storage solution as NFS.
It’s not possible to backup or restore a distributed vSwitch configuration.
Myth 5
• Helps take snapshots of working VDS configuration for deployments, rollback, and sharing purpose.
• Take snapshot of VDS and dvPortgroups configuration
DvSwitch Configuration Backup and Restore
DvSwitch Configuration Backup and Restore
The Following operations are supported:
• Backup VDS/dvPortgroup configuration on disk (Export).
• Restore VDS/dvPortgroup from a backup (Restore).
• Create new entity from backup (Import).
• Revert to the previous dvPortgroup configuration after changes are made.
Backup a VDS configuration
Restore a Port group Configuration
Restore a Port group Configuration
vSphere Distributed Switch
• Administrators can now save the VDS configurations and use it to restore the exact same VDS setup after any vCenter Server DB failure Scenario
• Network admins can also build a revision control system over VDS configuration by saving configurations after each change and use this to restore to any older configuration
• Saved VDS configuration can be used as template to create similar other VDS in any other deployment.
Myth Busted
• vSphere Distributed Switch – Enhancements such as Network Health Check, Configuration Backup and Restore, Roll Back and Recovery, and Link Aggregation Control Protocol support and deliver more enterprise-class networking functionality and a more robust foundation for cloud computing.
