Hi,
IBM has installed approximately 300 infrastructure clusters at
Oxfordshire schools in the UK. Each of these clusters has two IBM
servers running Linux, including DRBD (http://www.drbd.org) and
Heartbeat (http://linux-ha.org) to provide high-availability management
for the provided services.
IIRC, these services include:
proxy caching server
LDAP authentication using IBM's LDAP server running on DB2
DNS
DHCP
Samba file server services
etc.
In the end, each school has a highly-available, remotely manageable base
infrastructure which is resilient to disk failure, server failure,
software upgrades, hardware upgrades, other administrative events, etc.
Of course, this is not as ambitious as making your school
fully-Linux-run, but it will work for _any_ school, and is a modest and
very doable step in the right direction.
It is my understanding that because these services included "proxy
caching", that they were considered an "internet enablement" project and
were therefore subject to getting UK grant monies. It is my
understanding that in the US, that such clusters might possibly qualify
for Internet enablement grants from "erate" funding.
I hope the above statements don't cause any SPAM filters to assume this
is one of those Nigerian scams ;-).
