Storage is Easy for Hyper-V • Hyper-V hosts support a wealth of storage options • Root Partition for Hyper-V • Fixed Disk VHDs • Dynamic Disk VHDs • Cluster Storage Volume (CSV) [Multi-VHDs] • Pass-through Disk (Raw Disk)
Storage Options in Hyper-V • Support for VHDs up to 2TB* • Server8 support 2TB to 16TB • Multiple disk types supported per guest • Pass-through and iSCSI disks for guests
Your Hyper-V host is the sum total of your guests so plan accordingly
Storage Considerations • Lay out storage for your application(s) • Not all disk types are created equal • Design for your I/O Profile not capacity • Snapshots will cause extra I/O • Diff disks will be in use until VM shutdown • Pass-through disks do not support snaps
Backups are not easy • Hyper-V Host requires a backup • Virtual Machines require backup • Applications in VMs require backup • Files inside of VMs require backup • SYSTEM State Requires backup
Where do I backup from? • Backup virtual machines like traditional servers • Backup the virtual host configuration itself • Backup the virtual machines from the host • Backup the virtual machines from the storage • Backup the files in spite of the virtual machines Please sir, can I have some more options?
Backup Options • Pick a backup solution which meets your needs • Image backup • File backup • One-off Hyper-V only backup • Enterprise Solution (Networker, NBU, TSM)
How do I restore? • Restore VHD and recover files • Restore files direct • *Other Complex Recovery Options* • End-User Recovery • Backup Admin Recovery
Data Mitigation • Live Migration helps in planned disasters • Snaps can support quicker restores LM/Snaps are not backups*
Data Backup Concerns • LM/Snaps do not protect corrupt VHDs • Pass-through disks cannot be snapped • iSCSI Direct LUNs cannot be snapped • VSS Diff for snaps up to 15% of total VHD
General Best Practices Design for Applications Less disks less complex More data more backup Live Migration & Snaps are NOT Backups Understand Granularity Avoid point solutions*
