As i'm planning a new email infrastructure with Gluster storage, I would like to get a fully geographically redundant storage. Speed should not be a critical factor for a mailbox (I think) What would happen by setting a peer across a WAN connection ? (fibre 100mbit) ? Currenty I don't have 100mbit/s of disk writes on my email servers. In a replica 3, all reads are distributed across the whole cluster or only on first node? Because having all reads to cross the Internet is not good. Any advice? Georeplication is async, thus I can't load-balance the IMAP servers nor using a failover, because the replicated cluster is always out-of-sync
I've forgot: how much ram/cpu are needed by Dovecot Proxy/Director ? I have to evaluate some cloud services. Are there any specs like "128MB for each concurrent connection" and so on ? 2016-10-29 15:56 GMT+02:00 Gandalf Corvotempesta <gandalf.corvotempesta at gmail.com>:> As i'm planning a new email infrastructure with Gluster storage, I > would like to get a fully geographically redundant storage. > > Speed should not be a critical factor for a mailbox (I think) > What would happen by setting a peer across a WAN connection ?

You can feel even 10ms between the peers though, but for a mail server that probably won't matter, we used to be running VMs off that. -- Kevin Lemonnier PGP Fingerprint : 89A5 2283 04A0 E6E9 0111 -------------- next part -------------- A non-text attachment was scrubbed...
