Leverage storage array capabilities Maximize your investment Native access to SANs from VMs No tradeoffs Help reduce the cost of storage For workloads that don’t require a SAN Highly Scalable Virtual Disks Big data is here

Physical DAS (SATA, eSATA, PATA, SAS, SCSI) SAN (Fibre Channel, FCoE, iSCSI, SAS) Required for failover clustering so all nodes can access a disk Host clustering: Fibre Channel, FCoE, Serial-Attached SCSI (SAS), iSCSI Guest clustering: iSCSI, FCoE, Fibre Channel, SMB Virtual adapters IDE, SCSI Boot – IDE only Fibre Channel VHD (VHDX) Fixed, dynamic, differencing Pass-through iSCSI direct (applicable to running iSCSI in guest OS)

Create A Temporary VM On Destination Hyper-V Server 2. Connect Temporary VM’s HBAs To FC Fabric Using WWPN B 3. Verify Temporary VM Has Connectivity To Shared Storage 4. Complete Normal VM Live Migration (copy memory etc..) Limit IO Queue Depth To 1 5. Pause Source VM 6. Change Temporary VM To Permanent VM and Start IO 7. Logout of FC Fabric and Delete Source VM
