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
ESX(i) host(s)
Shared storage resources

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

Storage resources
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
