SAN JOSE, Calif. – PMC-Sierra, Inc. has rolled encryption technology into two new versions of its 6 Gbit/s Serial-attached SCSI controllers. The Tachyon SPCve chips let storage array designers provide embedded security as an alternative to external appliances, software, self-encrypting drives or separate security chips.
"We are in the data path, and this is the right place to handle security because the chips also can help control other storage functions like compression and de-duplication," said Kevin Burbank, director of marketing for enterprise storage at PMC.
The company announced 8- and 16-port versions of the security-enabled SAS controllers. Three years ago, PMC rolled out a similar set of Fibre Channel controllers with embedded security.
"Fibre Channel is still strong on the storage network side, Fiber Channel over Ethernet and iSCSI hasn’t replaced Fibre Channel there yet," said Burbank. "But SAS is replacing Fibre Channel on the back end as the drive interface," he added.
The new chips can work with hard drives or flash disks. They include four hardware encryption engines that handle inline encryption and decryption of data at throughput estimated at about 6 GBytes/second, about 90 percent of the maximum SAS data rate.
The chips have similar package and power requirements as controllers without security. They will be priced at about a 50 percent premium over parts without security features.
The new devices support the IEEE 1619 standard and 256-bit AES encryption keys. PMC provides security APIs and reference software along with the chips.
The components ride an eight-lane PCI Express 3.0 bus. They are sampling now with production before June.
