Indexes are very random, mostly read, some writes if using dovecot-lda (ej: dbox). The average size is rather small, maybe 5 KB in our setup. Bandwith is rather low, 20-30 MB/sec
We are using HP LeftHand for our replicated storage needs. Regards Javier El 11/05/2012 08:41, Cor Bosman escribió: > Hey all, we're in the process of checking out alternatives to our index storage.
