In addition, because the encryption would be performed with the processing power of the storage array's controller, it would reduce load on the network and on servers. At the same time, EMC wants to be sure the encryption capability doesn't slow down the performance of the storage array, Sadowski said.

EMC is planning to incorporate RSA's PKI management capabilities into the array as well, Sadowski said. The storage array would be used to back up key management information, authenticate key users and provide the appropriate key to appropriate parties, he said.

"These capabilities would address common problems, such as how to prevent database administrators from viewing sensitive data within their databases, as well as how to assure the integrity of information shared by multiple departments, or even multiple companies [such as business partners] on the same storage," he said.
