Solution Overview

Pure Storage FlashArray provides always-on deduplication and encryption of data at rest, providing a secure and efficient storage platform trusted by our customers.  Some customers have additionally decided to encrypt data at the host level, which has traditionally proved a challenge to storage-level deduplication such as that provided by FlashArray. This is because data reduction technologies rely on identifying repeatable patterns in the data and removing them whereas host-level host-level encryption has the effect of randomizing & scrambling the data that does not leave any repeatable patterns in it, thus preventing efficient storage-level deduplication. As a result, one has to trade-off host-level encryption against storage deduplication, which can in turn require the purchase of more storage capacity - not an ideal choice!
