Actually, Mr. Willett wrote that they (Storage Computer R&D) had ironed out the performance problems of RAID 3 and RAID 5 (by developing high performance RAID 7 over 10 years). >in this so-called "RAID7", I'd advise that you do a diligent search of >the literature about this so-called product. Try an altavista search >of the WEB and/or USENET looking for RAID7. Using AltaVista you would need to put in a space in the middle. Using AltaVista, you can search for "RAID 7" or just "RAID" to find quite a lot of information on the topic. (When searching with AltaVista, it's best to actually use the quotes.) Infoseek is also another excellent WWW search engine with the URL of http://www.infoseek.com/. The URL of AltaVista is: http://www.altavista.digital.com AltaVista produces better results on some kinds of searches, while Infoseek does better than AltaVista on others. >Earlier this year, I was at a conference in Germany where one of these >RAID7 vendors presented a grandiose plan for a "data fortress" or some >such malarkey, supposedly a foolproof way to protect your data by striping >it acorss multiple machines.

I believe Mr. Lumbley may be correct in this particular case. I am not aware that this product has been actually released or officially announced. Most large Fortune 100 companies do expect their computer vendors to make strategic presentations on future products, showing where they are going. >They also responded to my request for referenceable accounts with a Storage Computer has a large number of referenceable accounts in over 30 countries around the world, and the information is readily supplied to serious organizations. >The RAID 7folks point to relationships with a lot of the big vendors. >Take it with a grain of salt. Check them out with users, if you can. That's a good approach and makes a lot of sense. Potential users often check out their proposed storage vendors with other real users with large installations, helping to mimimize their risk. M Willett Storage Computer http://www.storage.com/
