We have two cs300's and a cs500 all at These store only VMware VMDK and related files. I know compression can vary widely bases on what data types are in given files. In our case we have mostly Windows 2k3 through 2k12r2 running file services, SQL, oracle on linux and various other apps, fairly typical mix of "stuff".


cs300-1: 21% compression with 28% of 15T used, 2% snapshot space

cs300-2: 27% with 60% of 15T used, 5% snapshot space

cs500: 39% with 30% of 51T used, 5% snapshot space


Are other people seeing better compression rates in this kind of environment?
