Which statement is accurate about deduplication on an XtremlO array?

Deduplication on an XtremIO array is a process where redundant data blocks are identified and only unique data is stored. This results in a reduction of the physical storage required, which is referred to as the deduplication ratio. As the deduplication ratio increases, meaning more redundant data is eliminated, the bandwidth effectively increases because less data needs to be transferred over the network.Additionally, latency decreases because the system has to process fewer data blocks, leading to faster response times1.

The Dell EMC XtremIO X2: Next-Generation All-Flash Array document explains that XtremIO’s in-memory deduplication is global across the entire cluster, which means that only unique data is written to the SSDs.This inline deduplication not only saves significant capacity but can also improve performance1.

The Introduction to XtremIO X2 Storage Array document details how the XtremIO X2 Storage Array automatically reduces (deduplicates and compresses) data on the fly, as it enters the system, which reduces the amount of data written to flash, improving the longevity of the media and driving down cost2.
