Hi Darren
The buildings are connected by fibre, currently with equipment running at
40gbps, soon to be 100gbps, with sub-millisecond latency, so if the data is
getting pulled from either building it's not a massive issue, as long as the
cluster can stay operational if an entire building goes
Hi Brett,
So how far apart are your buildings and what is the network connectivity
between the buildings? I am going to assume they are close and you have lots of
bandwidth.
There are a couple of options depending on the protocol and the distance
between the buildings.
You could build an EC
SD?

Hi Brett,
I'm far from being an expert, but you may consider rbd-mirroring between
EC-pools.
Cheers,
Lars

Hi Brett,
Our concern with Ceph is the cost of having three replicas. Storage
may be cheap but I’d rather not buy ANOTHER 5pb

Hi Brett,
Our concern with Ceph is the cost of having three replicas. Storage
may be cheap but I’d rather not buy ANOTHER 5pb for a third replica
if there are ways to do this more efficiently. Site-level redundancy
is important to us so we can’t simply create an erasure-coded volume
