The article reports on the use of a new tiered storage infrastructure by energy trading firm EDF Trading Ltd. to improve its performance. EDF Trading, whose parent company distributes electricity to London and the South East, has grown from a 14-person firm in 2000 to employ 250 staff worldwide. Managing information efficiently is essential to the company, which relies on up-to-the-minute trading information for its daily business. EDF's storage infrastructure is based around Cisco switches and EMC storage devices, all of which are mirrored at a disaster recovery centre. The top tier consists of mirrored EMC DMX 1000 high-speed disc arrays for storing essential daily data. Resilient, but expensive, the DMX 1000s give EDF the highest availability of all its data platforms. It includes fibre channel discs, with flat file data served by an EMC Celera file server, which is also mirrored at the disaster recovery site. EDF uses a client-server architecture based on HP servers running Microsoft Windows Server 2005 with Active Directory, an Oracle database and Biztalk. INSET: Virtual servers save space and money.
