Hi Bineesh,   Thank you for posting your question in EMC community. Please find below answers:   1. Are LUNs and Datastore same. If we create two Datastore in VNXE3150, can we say that two LUNs are created.   Datastore is nomenclature when it comes to Unisphere web interface. LUN is nomenclature when it comes to backend configuration. So datastore and LUN is same but just calls differently when it comes to web interface and command line configuration.   2. When creating Datastore(VMware) using Unisphere, is there any option to select RAID level.   When we talk about RAID level, you need to configure storage pool on VNXe. Storage pool can be configured on VNXe which is underneath a RAID group.   Navigate to system-->storage pools will show you storage pool configuration.   3. What is the difference between WMware Datastore and Generic iSCSI Datastore. I want to create Datastore for VMware VMs but i am using iSCSI for I/O.   The only difference between VMWare datastore and Generic iSCSI datastore is automatic API call. When you create datastore with VMWare option, VNXe triggers automatic API call which will format the datastore on ESX and present it has VMFS-3 with same name.     With Generic iSCSI storage, you need to manually discover iSCSI server IP (target IP) on ESX and format the datastore.   If you have VMWare environment in place, we always recommend to use VMWare storage option so that you can utilize virtualization features of VNXe   Regards, Swapnil
Hi All,  I have couple of queries related to DataStore. Kindly have a look at it and let me know your thoughts.  1. Are LUNs and Datastore same. If we create two Datastore in VNXE3150, can we say that two LUNs are created. 2. When creating Datastore(VMware) using Unisphere, is there any option to select RAID level. 3. What is the difference between WMware Datastore and Generic iSCSI Datastore. I want to create Datastore for VMware VMs but i am using iSCSI for I/O.    Here which Datastore is needed. VMware Datastore or Generic iSCSI Datastore.  Thanks in advance.  Regards, Bineesh
