Density & Easy Management of Hundreds of Terabytes
Scientific research is highly unpredictable by nature; often, leads which at the beginning appear to be promising are abandoned and others which had not initially been considered are pursued. This means that collaborations amongst researchers can change rapidly depending on the leads followed. In an ever shifting context, the IT system adopted must be sufficiently agile to adapt at any time. However, the storage volumes at play impose major constraints. The data gathered from both sea campaigns and satellites is very expensive and is unique as natural environments change constantly. As a consequence, this data must be secured and solid backup is required. The backup windows must be flexible in order to guarantee the global efficiency of the system. Indeed, backup cannot in any circumstances congest networks or slow down applications. Nevertheless, due to specific constraints, a continuous backup system is also being contemplated by LEGOS. Therefore, LEGOS needs both an efficient and scalable primary system for scientific projects (Nexsan systems for servers and work stations) and an appropriately-sized secondary storage system on dedicated hardware (older backup bays). Mr. Buisson’s concern is to “size the storage system correctly and provide the simplest and safest means of access to the data, so each and every scientific project can be carried out comfortably without affecting the others”.
