Make your storage work for you: VAAI and ODX offload up to 30% of disk operations to the SAN
The webinar discusses how to leverage ODX (Offloaded Data Transfer) and VAAI (VMware API for Array Integration) to improve storage operations by offloading up to 30% of disk operations to the SAN. It highlights the benefits of ODX for Hyper-V, including quicker disk operations and self-service provisioning of virtual machines. The presentation also covers hardware and software requirements for implementing ODX and the challenges with compatibility across different SANs.

- 7. 7 Offloaded Data Transfer(ODX) • A hardware offload introduced in Windows Server 2012 • Offloads slow operations and transfers from servers/hosts to the SAN • Results in much faster operations and happier customers • Hyper-V uses ODX for disk operations • ODX support added in System Center 2012 R2 PRESENTATION

- 9. 9 Benefits of ODXfor Hyper-V • Much faster disk operations, such as: • Creating fixed-size virtual hard disks • Extending fixed-size virtual hard disks • Live Storage Migration • Merging checkpoints (formerly AKA Hyper-V snapshots) • Clouds • Creating virtual machines from a library • Faster self-service provisioning of services PRESENTATION

- 12. 12 ODX Hardware Requirements •A SAN that supports ODX: • iSCSI • Fibre channel • Fibre channel over Ethernet (FCoE) • SAS • Always good practice to upgrade firmware and drivers throughout the entire storage stack • Check with SAN vendor • From HBAs to disks PRESENTATION
- 13. 13 ODX Software Requirements •Windows Server 2012, Windows 8, or later • System Center 2012 R2 (for Fast File Copy VM deployment) • Opted-in filter drivers (anti-virus, encryption, etc) • The affected volumes: • Unencrypted basic (not dynamic) partition • NTFS • Disable Data Deduplication and BitLocker on the volumes • No Storage Spaces • Files: • 256 KB or larger • Preferably not highly fragmented PRESENTATION
- 14. 14 Interesting Designs • Virtualmachine Guest OS can support ODX: • Guest OS iSCSI initiator is connected to LUN on ODX-capable SAN • Virtual machine is connected to LUN on ODX-capable SAN via virtual fibre channel • Hyper-V can use ODX over SMB 3.0 • File server or SOFS is connected to ODX capable SAN • Inter-SAN data transfers • Copy data between LUNs in different SANs using ODX • Requires storage controller support for inter-SAN ODX transfers PRESENTATION
- 15. 15 Caution! • Not allSANs offer the same level of support for ODX • ODX might be “supported” but unstable • Disable ODX: Set-ItemProperty hklm:systemcurrentcontrolsetcontrolfilesystem -Name "FilterSupportedFeaturesMode" -Value 1 • Some models of SAN offer great performance gains from ODX • Some barely show any benefit at all PRESENTATION
