DESCRIPTION
I'm going to start off talking a little bit about VMware vSphere 5. From there, we're going to go into some of the specific topics of how it's different for both virutalization administration and backup. Specifically, we're going to talk about the scale has changed. VMware vSphere 5 has really done a good job of scaling upward for virtual infrastructures. We're going to talk about what is virtual machine hardware version 8. Then we're going to talk about storage. vSphere 5 is often referred to as the storage release. We're going to go through a number of features, such as storage DRS, VDDK5, VMFS5, as well as the new version of HA. Then we're going to wrap up talking about how backups are impacted with vSphere 5.

How backups are impacted with vSphere 5
Why vSphere 5 Changes are Important
Over time our vSphere administration practice needs to change as the technology changes
● ESX 2 / GSX -> VMware Infrastructure 3● VMware Infrastructure 3 -> vSphere 4● vSphere 4 -> vSphere 5
The technology changes impact everything
● Virtual machine characteristics● Storage● Networking● Supported configuration
Impacts backup configuration, performance and design
Leading virtualization platform
About VMware vSphere 5
Robust features: DRS, HA, VMFS, Advanced storage

About VMware vSphere 5
First major series to be ESXi only● Important for anything where host-based agents are required
ESXi – vmkernel
Hardware monitoring agents System management agents
Host processes and 3rd party agents
Major Changes in Scale
Incredible limits for the virtual machine● 32 vCPUs, 1 TB RAM among others
Scaled up hosts● 2 TB RAM, more network interfaces
vSphere 5 Configuration Maximums
● http://vee.am/vSphere5Max ● Authoritative resource
for vSphere configuration parameters
Virtual Machine Hardware Version 8
Updated with vSphere Client or Update Manager New configuration maximums permitted
with new virtual machine hardware Up-to-date configuration is important
for feature-rich backups
New virtual machine format for vSphere 5● Version 4: VMware Infrastructure 3● Version 7: vSphere 4● Version 8: vSphere 5
Major Changes in Storage
Most vSphere 5 major new features are for storage Advancing features for additional performance
ESX(i) host(s)
Storage resources
iSCSI NFS DASFibre
Channel
Not just limited to VMFS
● Storage I/O control for NFS● VAAI offloads for NFS storage
Storage DRS
Technique to pool VMFS volumes logically
Logicaldatastore
VMFS Cluster at 6 TB
6 individual VMFS-5 datastores (6x1 TB, example)
Storage DRS
Core metrics: free space and latency Allows administrator to customize priority for response
VDDK 5 Virtual disk development kit 5 was released with vSphere 5,
updating the previous release from vSphere 4
Use for hot-addof virtual disks
Code-level changes
Many backup products may use hot-add for improved backup performance
● Reads● Writes

Traditional explicit VMDK assignment to this VM
During a snapshot,temporary co-mappingof VMDK
VMFS-5
For fibre channel and iSCSI storage protocols VMFS is a clustered file system
● Purpose built for virtual machines● No coordinator node or software mechanism
VMFS-3 is both backward and forward compatible● vSphere 5 can downward format at VMFS-3 (3.54)
Easy to upgrade from VMFS-3 to VMFS-5● Consider new format
Numerous enhancements● 1 MB block size● Sub-block algorithm● Atomic Test and Set (ATS) primitive command
Block size now supports all support file sizes● Important for snapshots
VMware HA Rewritten for vSphere 5
Protects against host failures
New HA architecture: Fault Domain Manager (FDM)
No dependency on DNS
● Still provision DNS in a correct, robust manner
New master / slave node concept
vSphere 5 Clustering technical deepdiveBest book to learn this and other vSphere features
How Backups are Impacted with vSphere 5
Changes in core features, such as VDDK underscorethe importance of full support of vSphere features
Clean configuration is critical to successful backups:
● Storage● Networking● Virtual machine up to date● Supporting infrastructure
