SRDF

SRDF is an EMC product family that provides synchronous or async data replication between LUs (logical disk units) of two SAN (Storage Area Networks).

Here is a story about how data replication saved the day in a trading environment at a Tier-1 bank.

Here is a description of a high-performance trading system that uses SRDF. The brochure contains some good points to consider when designing the infrastructure of a trading system. These kinds of infrastructure components were things that I never had to consider previously when I was concentrating solely on writing good software and managing development teams, but in the architecture group, I have to pay attention to this stuff now.
