Buses


n Parts 1-4 of the Future Storage Systems articles, we focused on the SAN-facing technologies that would enable scalable propcessing growth, purpose-built technologies for deduplication and encryption, as well as the fabric that would tie nodes together.  However, in each of these articles, I never got into WHERE  that information would eventually be stored.  Today, I’m hoping to remedy that problem.  I’ll be referencing the diagram below as usual.

Search Term Reviews: October 15th Edition

It’s been awhile since I last did a review of what people are searching for (July 30th was the last time…wow) so, let’s see what’s new.

Search Term #1: EMC NX4

Not really suprised here.  Honestly, take the Celerra NS-20, cut the price signficantly, allow blended SAS/SATA drive trays, [click to continue…]

So, I’ve been toying around with this in my mind for some time.  Essentially, I’ve tried to understand the basic “Storage Processor” limitation of current storage systems and propose an admittedly simplistic design to get around some of the difficulties.  The biggest hurdle, in my mind, is to have cache coherency, low latency memory access to other nodes in a “cluster,” and have a communications “bus” between nodes that is extensible (or at least will grow bandwidth with more devices on the signal chain).  Staring at that problem, then, look at the image below.
