A. Inline Compression is enabled by default, administrator does not need to do anything D. For cold data (no read/write for 3 days). As data cools, LZ4HC further compresses it to improve the compression ratio. https://portal.nutanix.com/page/documents/solutions/details?targetId=TN-2032-Data-Efficiency:TN-2032-Data-Efficiency

Agreed. Almost always use inline compression (compression delay=0) because this setting only compresses larger or sequential writes and does not impact random write performance. In fact, inline compression typically increases effective performance by increasing the usable size of the SSD tier. In addition, when the system replicates larger or sequential data for protection, it can send compressed data, further increasing performance because less data crosses the wire. Inline compression also pairs perfectly with erasure coding.
