Chapter 11: Brocade Data Encryption Productsused for cross-site backups, where data stored at one site is backedup to a tape library located at another site. Figure 50 demonstrateshow the data-in-flight for a cross-site backup can be encrypted using adata-at-rest encryption solution.asSite ACiphertextSite BBrocadeEncryptionSwitchEncryptedframe payloadServersTape libraryFigure 10. Encrypted cross-site backupSimilarly, this same strategy could be used for data replicationbetween two sites.Figure 51 illustrates how a data-at-rest encryption solution can be usedto encrypt data on the dark fiber during data replication. In this case, thedata stored on the primary data center is encrypted using the encryptiondevice. The disk-to-disk replication application (such as EMC SRDF orIBM PPRC) will simply copy the data which is already in ciphertext formatto the alternate site where it will be stored as is in ciphertext.The latest Brocade FC products are based on the 16 Gbps Condor-3ASIC. This new ASIC has built-in encryption and compression capabilitiesthat allow SAN administrators to configure up to two ISL ports (E_Ports)per ASIC for data-in-flight encryption. This feature may also be used toencrypt replicated disk data between two sites or for cross-site backupswhen both sites are connected via ISLs using dark fiber. A new 16 Gbpsswitch at one data center will encrypt outbound frames on the ISL andget decrypted at the other end by another 16 Gbps FC switch. The Condor-3ASIC is also capable of compressing data. As seen previously, it isnot possible to compress encrypted data, so the compression is the firstoperation to take place when used in conjunction with encryption.196 Securing Fibre Channel Fabrics
Chapter SummarySite ACiphertextSite BBrocadeEncryptionSwitchServersTape libraryFigure 11. Encrypting data over dark fiber with data-at-rest encryptionChapter SummaryBrocade provides encryption solutions for both data-at-rest and datain-flight.The Brocade Encryption Switch and the Brocade FS8-18Encryption Blade for the Brocade DCX backbone family can be usedfor both disk and tape media to encrypt data-at-rest. The Brocadeencryption switch is a standard 8 Gbps Layer 2 FC platform and, whenused in encryption mode, provides robust encryption (and compression)in combination with third-party key management. The addition ofa Smart Card reader for an ignition key provides additional security.Brocade offers data encryption for data-in-flight in the Brocade 7800Extension Switch and Brocade FX8-24 Extension Blade, both of whichsupport IPSec for encryption of data transported over an FCIP tunnel.The Brocade data-at-rest encryption solution, described in detail inthis chapter, can be used to encrypt data-in-flight. The encryptiondevice in the primary data center encrypts the frame payload beforesending it over the dark fiber connection.The latest Brocade 16 Gbps FC technology, based on the Condor-3ASIC, also offers the capability to encrypt data-in-flight for up to twoISLs.Securing Fibre Channel Fabrics 197
