Chapter 11: Brocade Data Encryption ProductsOne advantage of using encryptino blades is that you do not need tobe concerned with ISLs, since all of the encryption is performed via thebackplane. It is not necessary to connect the hosts or storage devicesinvolved in the encryption process into one of the 16 FC ports on theblade. In fact, encryption will take place even though there are nodevices directly connected into the blade. This is accomplished usingthe frame redirection technology described in “Frame Redirection” onpage 33.Brocade Encryption FeaturesThe Brocade encryption solution offers several features that wereintroduced in releases of Fabric OS subsequent to the initial release ofthe hardware.The following are the encryption features of the Brocade encryptionsolution:• NetApp KM500 Applicance• EMC Data Protection Manager (DPM, formerly RKM)• HP Enterprise Secure Key Manager (ESKM)• IBM Tivoli Key Lifecycle Manager (TKLM)• Thales e-Security keyAuthority (formerly TEMS)• SafeNet KeySecure• Symantec NetBackup• EMC NetWorker• CommVault Data Protection• HP Data Protector• BakBone NetVault• CA ARCserv• Symantec Backup Exec• Microsoft System Center Data Protection Manager• Disk encryption• Tape encryption• Offline, in-place, first-time encryption and rekeying• Online, in-place, first-time encryption and rekeying• High availability (HA) cluster178 Securing Fibre Channel Fabrics
Brocade Encryption Features• Data encryption key (DEK) cluster• DataFort compatibility mode• FIPS 140-2 Level 3• Common Criteria (EAL-4+)• Multi-path rekeying to a LUN through an EE• System card to enable crypto capability• Quorum authorization of sensitive operations• Access Gateway for third-party support (switch only)• LUN DecommissioningBrocade Encryption ProcessThe Brocade encryption solution uses the industry standard AES-256encryption algorithm implemented in hardware:• Disk encryption is performed using the XTS mode of encryption,which is better suited for fixed-block data• Tape encryption is performed using the GCM mode of encryption,which is better suited for variable-length and streaming dataCompression is an important component of a data-at-rest encryptionsolution for tape. Once data is encrypted, it is no longer compressible.Compression works on the principle of searching for patterns and optimizingthem. Encryption takes data and removes all patterns byrandomizing the data. Once the data is randomized and all patternsare removed, then the compression algorithm has no patterns to optimize.If encrypted data is sent directly to a tape drive, the nativecompression capabilities of that tape drive will no longer be effective.Hence, it is important to compress the data first and then send it tothe tape drive to prevent an unnecessary increase in the number oftape media used for backups.The compression algorithm used in the Brocade encryption solution isbased on a variant of the standard gzip algorithm. The compressionratio obtained using this compression algorithm may vary, like anyother compression algorithm, depending on the type of data and howcompressible it is. Data with a a great deal of white space compressesquite well, while some data may not compress at all.CryptoTarget ContainersA Crypto Target Container (CTC) is created for each storage target porthosted on a Brocade encryption device and is used to set up theencryption to a media. A CTC can be composed of only one storageSecuring Fibre Channel Fabrics 179
