I did some of the original implementation (ten years earlier than the referenced email) ... abut the same time that also i worked on some of the original relational/sql implementation. http://www.garlic.com/~lynn/subtopic.html#systemr i've since gone thru a couple complete rewrites from scratch. http://www.garlic.com/~lynn/index.html it is what i use for my rfc index http://www.garlic.com/~lynn/rfcietff.html and the merged taxonomy and glossaries http://www.garlic.com/~lynn/index.html#glosnote

That would be Mosis most likely and you don't get the latest stuff. Or very many square mm. If you want 65nm or even maybe 45nm SOI you gotta pay. del cecchi

How much does a real mask cost nowadays?

With a 32+7 ECC code they could transparently recover from both 'high-level' writes and misaddressed writes, along with the usual read errors. Most RAID systems today depend on the disk itself to tell that there's a problem with one of the inputs: Recovering from silent faults require more redundancy. > > We also offer double-capacity DVs with 84 drives; no more bandwidth, > just a 2nd tier of drives off of each channel. BTW, how much data were they capable of stuffing onto those 32 (or 64) data drives at that time? Around a GB/shelf?
