Hello all.
--- Where we are ---
Currently, I've got a single site, colocated on the East Coast. Currently, I've got two NetApps at that site, one serving as a mailspool, the other serving as a location for web documents. This system works via NFS to a fair number of mail and web servers, and it's running happily.
--- Where I'm going ---
What I seek is some help on implementing a second site, and the link between the two. The sites will be more or less the same in terms of the equipment in them, or so I hope.
I want to be able to have the changes made at one site replicated to the other site transparently. That is, if I update a file at site A, I want to be able to see the changes at Site B in a reasonable period of time (i.e., short), and without having to manually move data around. I specifically want to do this for allow both sites to offer the same mailspool, so that customers can check their mail at either site.
I am in the planning phase of bringing up a second site, and at this site, there will be more web servers, and more mail servers. There will also be an additional netapp for each of mail and www.
Between the pair of mail netapps (and to a lesser degree, the www netapps), I want them to replicate changes to the other one. That is, if a file is removed on Mail.NetApp A, it should also disappear on Mail.NetApp B. And if a file is created on netapp B, it should also come into existance on netapp A. Bidirectional updates.
My current setup consists of Linux and FreeBSD systems, and F740 NetApps.
And yes, there is a lot of pressure to stay with the NetApps.
Any hints, or advice will be much appreciated.
You probally want something like snapmirror, but when a file is changed/deleted in the mailbox, you hack your pop/imap server to delete the file on the 'master' fileserver. this isn't really on-topic though, imho. - jared -- Jared Mauch | pgp key available via finger from jared@puck.nether.net clue++; | http://puck.nether.net/~jared/ My statements are only mine.
