Dovecot + SAN with dedup+compression

[María Arrea]

Hello

     We have a big Dovecot Server (over 20 TB of mail, 40K users, over 
30K iops) and we are evaluating a new SAN Array. We have competitive 
proposals from Pure Storage (All Flash) , HP 3Par (Hybrid), NetApp FaaS 
(Hybrid) & EMC Unity (Hybrid). We rely in mdbox+zlib for main storage 
and mdbox+lzma for secondary storage, does anybody in the list have 
experience with SAN-based deduplication/compression?
     Regards
     Maria.
