 ==== Storage Capacity Upgrade ====
-Adding additional storage capacity to the NAS is easy. The NAS is setup to accept the failure of two hard disks at the same time without losing any data from storage. This requires a large amount of storage overhead for limited disk arrays but allows subsequent disks added to contribute almost all of its space towards the effective capacity. This means that by adding a single, 3TB disk to the current setup the total effective storage space will also increase by 3TB, and so on for additional disks. Below are the specifications for a hard disk:

-The OBCP cluster was purchased as part of a loose coalition between the Ohio Biodiversity Conservation Partnership (OBCP), the [http://ael.osu.edu/ Aquatic Ecology Laboratory (AEL)], and the Center for Biodiversity Research & Analysis (CEBRA) and provides computational support for parties associated with these groups. The cluster is designed to facilitate population genetics, ecological modeling, phylogenetic analyses, or any other computationally intensive scientific need for the researchers involved.

The cluster is designed to facilitate population genetics, ecological modeling, phylogenetic analyses, or any other computationally intensive scientific need for the researchers involved.
 Rather than begin with a restrictive policy towards resource utilization per user, we intend to take a more hands-off approach that assumes that all users will exhibit self restraint towards resource monopolization. Although potentially naive, we do not want to create an unnecessary impediment towards cluster usage that may occur from firm CPU / memory limits, batch job queuing, etc. If you are having difficulties with successfully running a task which you believe is caused by a lack of available cluster resources, please email [mailto:cora.1@osu.edu Joe Cora] and explain your issue. A restrictive policy towards resource usage will be enacted if a proper equilibrium amongst users can not be achieved organically.
