This document is an analysis of the Hitachi Protection Platform backup appliances, the S2500 for the central datacenter and DR site(s), and the S1500 for the remote office/branch office (ROBO).
These appliances are successors to the Sepaton S2100 following the acquisition of Sepaton by HDS in August, 2014. The S2500 competes at the high end with products from EMC, HP, IBM, NEC, and Quantum. It is essentially a hardened version of the Sepaton S2100-ES3. The S1500, made generally available in June, 2015, is a new addition to the product line.
The S2500 is designed to be the central datacenter repository for backup data and/or the repository at a DR site. It can serve as the hub for spokes out to S1500 appliances in remote/branch offices.
The S2500 is a grid architecture disk-based backup appliance that can scale capacity and performance independently for enterprise environments.
Using standard Hitachi storage on the backend and supporting major backup applications on the front end, the S2500 requires no client or host agents.
