Bloombase Spitfire Ethernet Encryptor can be deployed in a real-time storage data replication environment such as in above visual. Delta changes committed to primary storage sub-system are picked up by SAN router at primary site and packaged into IP data to be synchronized to remote secondary site for data mirroring. Spitfire Ethernet Encryptor works as a charm to encrypt outbound sensitive storage data before they are traversed through the unsecure MAN/WAN via SONET or dark fiber. Another Spitfire Ethernet Encryptor resides as gateway to the destination site, decrypts incoming ciphered SAN delta changes before they are applied to the disaster recovery storage system.
