Steve Johnson, who works in storage architectural strategic planning with LSI's Corporate CTO office, leads us through the use of a new 12Gb/s SAS 40- port expander in development. The use of SAS expanders will help enable flexible and shareable storage volumes within a scaleable SAN-like architecture.

The use of switches to connect all storage in a DAS environment allows for more complex RAID schemes to significantly reduce RAID rebuild times. Utilizing the 12Gb/s MegaRAID controllers in tandem with a new LSI technology, dubbed 'D-RAID', will provide a massive reduction in RAID rebuild times, from a week to within roughly 20 min per volume.

The quest for benchmark world records led Paul further and further down the overclocking rabbit hole. SSDs and RAID controllers were a big part of that equation, allowing him to push performance to the bleeding edge. Finding the fastest and most extreme storage solutions led to experience with a myriad of high-end enterprise devices. Soon testing SSDs and Enterprise RAID controllers at the limits of their performance became Paul's real passion, one that is carried out through writing articles and reviews.
