In the scenario where a consultant is viewing an ESXi host via console without external network connectivity and needs to connect to the Controller Virtual Machine (CVM), the typical IP addresses used for such connections in a Nutanix environment are in the 192.168.5.x range. Specifically, the IP addresses for CVMs often set by default or during initial configuration, such as 192.168.5.253 and 192.168.5.254 (Options A and C), can be used. These addresses are generally reserved for internal CVM communications and can be accessed through the host's internal network configurations.References: Nutanix Cluster Installation Guide, Default Nutanix Network Configurations.

To meet the requirements of maximizing storage space savings while optimizing I/O performance for business-critical applications and general server workloads, enabling both compression and erasure coding on the storage containers is recommended. Compression reduces the data footprint on storage disks, while erasure coding provides data redundancy in an efficient manner, which not only saves space but also enhances data durability and I/O performance for read-intensive applications.References:
