Research Council UK (RCUK), which is responsible for co-ordinating all scientific research at UK universities, has updated its storage area network (San) with mutli-tiered storage to lower costs.
RCUK had a large information repository which was pushing existing storage systems to capacity. It was holding millions of data files, many of which were infrequently accessed but had to be kept for auditing purposes. It also held about two million files attached to the database which needed to be kept for auditing.
This was an expensive way to store infrequently accessed legacy data. RCUK has now deployed a Compellent Storage Center San, which uses tiered storage to reduce the costs of long-term low-level storage in comparison with the existing San.
The tiered storage and automatic data migration of the Compellent Storage Center San means that infrequently accessed data is automatically migrated to lower-cost SATA drives with no involvement needed from the storage administrator, according to RCUK.
