ISP Information:
This form of RAID was originally called RAID 1+0, and is now commonly referred to as RAID 10. This is basically a bunch of RAID 1 drives linked together with RAID 0. Hence you get the speed benefits of RAID 0 with the redundancy benefits of RAID 1. The only problem is that you use a lot of drives to do it. Like RAID 1, you only get half of the space that you've paid for. Of course it may be worth it if you can rest easie

RAID 10 - On 22 Mar 2004 07:48:57 -0800, hancock4@bbs.cpcn.com (Lisa Hancock)wrote: All calls by prison inmates are made collect. The recipient must pay extremely high charges.There is another, relatively new, growing problem -- the fact thatcollect calls are becoming an anachronism because of the growingamount of competition in the telecom business.* Try calling a cell phone collect -- can't do it.* Try calling a number served by a CLEC collect -- in the vastmajority of cases, can't do it (most CLECs refuse to handle billingfor other carriers and so most CLEC customers can't receive collectcalls.)* Try calling a number served by a VoIP provider (Vonage, VoicePulse,etc.) collect -- can't do it. (VoIP providers are invariablycustomers of CLECs, and don't want to handle billing for othercarriers either.)I know quite a few people who would be unable to call *anyone* if theywere to be arrested because the only numbers they have for friends andfamily are cell phones, CLEC or VoIP numbers, etc. (I still have aBellSouth POTS line that is not restricted from receiving collectcalls, but very few people have the number ...)IMO, the whole "prison phone" business is in need of serious reform,and not just because of what the carriers handling the calls arecharging and where revenues are going. The mindset that "everyone isstill a customer of the ILEC and can receive collect calls" is simplyobsolete -- there has to be a better way.Stanley Cline -- sc1 at roamer1 dot org -- http://www.roamer1.org/"Never put off until tomorrow what you can do today. There mightbe a law against it by that time." -/usr/games/fortune[TELECOM Digest Editor's Note: When I was living in Skokie, Illinois(Chicago suburb, and god -- how long ago it now seems) I had a neighbornamed Ken who was employed by the Cook County Jail as an 'intake clerk';that is, a person who sits there checking in new inmates (of whichthere are several hundred every 24 hours.) Ken was not precisely amodel citizen himself and had gotten his job at the jail through thepatronage system (what else is new?) because he had probably votedfor, and encouraged others to vote for the 'right candidate' for oneof the various government offices. The person got elected and handedout many jobs to reward his workers. But Ken could make sense now andthen when speaking frankly about jail conditions.He said it was all too often that an arrested person getting to thejail would ask about being allowed to make a phone call to his wifeor family to let them know where he was at, and it was a situationwhere jail (inmate) phones were 'incompatible' with the phones usedby the general public (which is to say, the recipient could notreceive a 'collect' call, and jail phones did not allow one to placea call to an '800' number, etc.) "The police who brought me heresaid I would be allowed to make a call when I got here, I have beenin booking for eight hours, and still can't make any calls!"Ken said if the newly arrived inmate was an 'asshole' he would justfollow the script and tell him "try calling from the phone in yourcell block when you get there", knowing that would not work either,but hoping the new inmate was unaware of it. "But then one day, therewas this very mild-mannered older guy getting checked in who said tome, 'what if *you* were on the 'wrong side of the counter for a changegetting checked in?'" Ken said he thought about that silently andsaid silently to himself, "well, only through Gods grace I am not,"so he handed *his* phone to the man and said "go ahead and dial alocal call." The old dude was so grateful that someone had given hima chance to make a one minute phone call to his family.Cook County Jail is on the same phone centrex (773-890) as the inmate'scell block phones, but the employee phones are unrestricted. Theycost no more or less to use for local calls than the inmate phones,and because it is a HUGE centrex (the entire 773-890 range) they morethan likely get calls cheaper than 'regular citizens' anyway. Sowhy not allow them to be used sinc
