SnapDrive supports the use of ESX iSCSI initiators, but there are some limitations you must keep in mind.
- SnapDrive does not support iSCSI session management using ESX iSCSI initiators.
You can add targets from the initiator list during LUN creation and connection.
- Multipathing using both FC HBA and ESX iSCSI initiators is not supported.
- Multipathing using both Microsoft iSCSI Software initiators and ESX iSCSI initiators is not supported.
ESX iSCSI initiators require RDM files to provision a LUN, but Microsoft iSCSI Software initiators do not have this requirement.
VMware limitations
- RDMs are not supported on an NFS datastore; however, you can store RDMs in any connected VMFS datastore if the virtual machine is stored on NFS.
- MPIO is not supported in a guest OS.
- Windows Server 2008 failover clustering is not supported using ESX iSCSI RDM LUNs.
- RDM LUNs larger than 2 TB are not supported.
- IA64-bit operating system is not supported as a guest OS.
