The other reason is the uptime > requirements. the DS<X> or the old T<X> standard does not still deliver better performance, reliability or maintainability/manageability than a network cable plugged into the rack switch in a hosting facility. Also, with these sort of telco links in ( not consumer grade adsl etc ) one needs fairly expensive and hard to manage LTE kit. Then there is the p-o-f issues. In this day and age, building out a facility inhouse only makes sense if you have hundreds or more servers or need a facility that has no internet links ( very very few of those these days ) or you are a hosting company looking to build 30,000 odd sqft space to then lease out and are going to plumb in multi fibre inbound. Think about it - do you even want Inergen Canisters floating around a residential facility ? Halon 1301 ? Or are you going to put in a sprinker system and hope the insurance man does not test-run it and kill every bit of electric equipment you have on site. Just my 2bits. -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh ICQ: 2522219 | Yahoo IM: z00dax | Gtalk: z00dax GnuPG Key : http://www.karan.org/publickey.asc _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
