Storage Security Performance Challenges

Our favorite storage pundit Henry Newman writes on the performance challenges of Storage Security:
“We all know that the complexity of the calculation of a checksum is far less than the complexity of an encryption algorithm. Complex encryption algorithms are computationally intensive and commodity CPUs are not likely the best place to do this type of algorithm. These types of algorithms are best suited to specialized hardware such as an ASIC or some of the faster FPGAs. CPUs are getting faster and faster but memory bandwidth is not growing at the same rate as CPU performance, and moving data in and out of memory to encrypt it and decrypt it in systems that do a lot of I/O (databases, video and audio applications and backup systems) will not likely be able to keep up with the decryption requirements to ensure that the machine can meet I/O requirements.

About Rich
FlexRex began his life as a cartoon character I created a Sun Microsystems. As the world's first "fictional blogger," he appeared in numerous parody films that made fun of the whole work-from-home thing. Somewhere along the line, the Sun IT department adopted FlexRex as their spokesman in a half-dozen security awareness films for employees. So when I left Sun recently, I started FlexRex Communications, a Marketing company in Portland, Oregon.
