 Temperature Sensitive Storage Efficiency (TSSE) is a method of compressing data based on data “temperature”, or how often the data is used. “Cold” data, or data that is not used often, is recompressed with a higher compression ratio for increased storage efficiency. TSSE is enabled automatically on newly created thinly provisioned AFF volumes, not thick provisioned volumes. TSSE operations on AFF arrays are automatically throttled depending on whether data is hot or cold, to balance performance and efficiency. TSSE is not supported on Cloud Volumes ONTAP or ONTAP Select, as these platforms have different storage characteristics and requirements. References :- Temperature-sensitive storage efficiency overview, How does Temperature Sensitive Storage Efficiency affect SnapMirror?, ONTAP Temperature Sensitive Storage Efficiency (TSSE) – A Simple Introduction

The space guarantee setting determines how much space is reserved in the aggregate for the volume. A space guarantee of “none” means that no space is reserved for the volume, and the volume can use any available space in the aggregate. This approach to space management is called thin provisioning. This setting would prevent the hosting aggregates from showing a decrease in available space when creating new volumes, as long as the aggregate is not overcommitted. References :- How volume guarantees work with FlexVol volumes, How you set space guarantees for new or existing volumes, What is the impact of changing volume space-guarantee from “volume” to “none”?

The point-to-point topology is the simplest and most common way to connect a single host to a storage system using FC. It allows direct communication between two devices without any intermediate devices. The UTA2 ports on the AFF A220 cluster support the point-to-point topology when configured as FC ports. Therefore, to connect a single Windows host directly to the storage using FC, you need to use the point-to-point topology on all ports and make sure that the host and the storage have compatible FC settings, such as speed, WWPN, and zoning. The other options are not correct because they involve additional devices or topologies that are not necessary or supported for this scenario. References :- Quick guide - AFF A220, Detailed guide - AFF A220, ONTAP 9 SAN Configuration Guide
