 --- | --- 
 **Target location** | Specifies the Azure VMware Solution private cloud location to which you want to migrate.
 **Storage type** | Specifies the storage engine to be used in Azure VMware Solution. vSAN is part of all AVS SKUs' storage. Azure NetApp Files (Standard, Premium, and Ultra tiers) is used by default in the assessment if external storage can optimize the number of AVS nodes required.
-**Reserved Instances (RIs)** | This property helps you specify Reserved Instances in Azure VMware Solution if purchased and the term of the Reserved Instance. Your cost estimates take the option chosen into account.[Learn more](../azure-vmware/reserved-instance.md) <br/><br/> If you select reserved instances, you can't specify "Discount (%)".
-**Node type** | Specifies the [Azure VMware Solution Node type](../azure-vmware/architecture-private-clouds.md) used to be used in Azure. The default node type is AV36. More node types might be available in future. Azure Migrate will recommend a required number of nodes for the VMs to be migrated to Azure VMware Solution.

+**Node type** | Specifies the [Azure VMware Solution Node type](../azure-vmware/architecture-private-clouds.md) used to be used in Azure. By default all node types available in the selected region are used for the assessment. Currently, AV64 node type can only be used along with AV36, AV36P, or AV52 and cannot be used as a single node type in an SDDC. The node type available for use will depend on the capacity availability of the SKU in the region.
 **FTT Setting, RAID Level** | Specifies the valid combination of Failures to Tolerate and Raid combinations. The selected FTT option combined with RAID level and the on-premises vSphere VM disk requirement will determine the total vSAN storage required in Azure VMware Solution. Total available storage after calculations also includes (a) space reserved for management objects such as vCenter Server and (b) 25% storage slack required for vSAN operations.
 **Sizing criterion** | Sets the criteria to be used to determine memory, cpu, and storage requirements for Azure VMware Solution nodes. You can opt for *performance-based* sizing or *as on-premises* without considering the performance history. To lift and shift, choose as on-premises. To obtain usage based sizing, choose performance based.
 **Performance history** | Sets the duration to consider in evaluating the performance data of servers. This property is applicable only when the sizing criteria are *performance-based*.
