UK Retail giant Co-Op opts for DataCore Software
Co-Op Jersey has implemented DataCore Software's SANmelody software-based storage-area network (SAN) as shared storage to support a VMware-based server virtualisation project. The resulting iSCSI SAN -- which replaced existing direct-attached storage (DAS) -- runs on two IBM servers in which all disk writes are replicated instantly across the wide-area network to provide total redundancy.
"Downtime for maintenance and provisioning new servers isn't acceptable," said Don Le Clercq, IT manager at Co-Op Jersey. "To enable this, we have used a combination of two IBM servers along with DataCore's SANmelody to provide a synchronously mirrored high-availability architecture."
