6. Storage Management

7. The new VHDX virtual disk format
• New VHDX format for Hyper-V & Win8 Storage
• Large virtual disk size (~ 16TB per VHDX)
• Large default block sizes (1MB  32MB  256MB)
• Large 4KB sector size (logical + physical same size)
• Performant
• Mountable
• Resilient
• Convertible
• Scriptable

8. File Services with Pools & Spaces
• Windows 8 Role and Role Services

9. File Services with Pools & Spaces
• Pool is an aggregation of disks
• Create virtual disks
• Virtual disks = Spaces
• Virtual disk behaves like a physical disk
– Supports Thin provisioning
– Resiliency to failures of physical disks

10. Integrated iSCSI Target Server
• ISCSI Target Server
• Optional component of Windows 8 File Server Role
• Easy serving of iSCSI disks
• Hardware independent
• Cluster Support
• CSV Support
• PowerShell Support

11. Deployment Options for Hyper-V

12. Deployment Options for Hyper-V
1. External Storage Array
– New functionality: ODX & Trim
2. File Servers - Pools & Spaces
3. Clustered PCI RAID

13. Offload Data Transfer (ODX)

14. Deployment Options for Hyper-V
• Two separate clusters • Single cluster for VM’s
– Cluster to host VMs and storage
– Cluster to host storage – VMs can run anywhere
– Single CSV namespace

15. Cluster Shared Volumes 2
• Appears as CSVFS
• For Hyper-V + other roles
• Easy to add a disk to CSV
• Higher scalability and reliability
• Better interoperability with FS mini-filter drivers
• Deep integration with Win8 storage & network technologies
• No external authentication
• Direct I/O for more scenarios
• Multi-subnet Support

16. Cluster Shared Volumes 2
• High Speed CSV I/O Redirection
• CSV is integrated with SMB multi-channel
– CSV traffic across multiple networks
– Improved I/O performance when in redirected mode
• CSV takes advantage of SMB2 Direct (SMB2 over RDMA)

20. Big thanks for attending!!
You can build great
continuously available
platforms that shine with
Hyper-V across a wide range of
storage deployment options
