3 Storage is Easy

4 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)

5 Storage Types in Hyper-V

6 Storage in Hyper-V Clusters

7 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

8 Your Hyper-V host is the sum total of your guests so plan accordingly

9 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

10 Backups are not easy

11 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

12 Choose your granularity

13 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?

14 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)

15 Recovery is ever harder

16 How do I restore? Restore VHD and recover files Restore files direct *Other Complex Recovery Options* End-User Recovery Backup Admin Recovery

17 New Hyper-V Support Full virtual server protection Guest level backup and recovery – Application-aware protection for Exchange, SQL, SharePoint, etc. – Fine-grained recoveries Hyper-V Image backup and restore – Disaster recovery – Complete protection of virtual hard disk (VHD) files – Recover guests to alternate Hyper-V servers – Granular Level Recoveries (GLR) from image backups in minutes IN-GUEST

18 Federated Hyper-V CSV Backup Federated Hyper-V CSV Backup Support – Scheduled VM backups from the CSV Cluster – Supports live migration of VMs to different Hyper-V CSV node Flexible CSV Backup Scheduling – Backup all VMs in the CSV cluster – Backup Individual VMs

19 Data Mitigation Live Migration helps in planned disasters Snaps can support quicker restores LM/Snaps are not backups*

20 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

21 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*
