     1The core cluster includes the infrastructure needed to operation manage UABgrid.  The cluster is currently composed of two vm hosting computational platforms and a data store.  The core cluster hosts the identity management, vo management, job control, and key collaboration applications for UABgrid.

     3It is envisioned that this core will support redundancy via services hosted at multiple sites. This is a long range plan and not part of the initial infrastructure.

     7The existing hardware components are: 
     8 
     9 * 2 Dell 2950s with 8Gb RAM 300 Gb SATA drives 
     10 * 1 Dell 1950 that acts as a multi-protocol NAS front-ends 
     11 * 1 6TB Dell/EMC disk array 
     12 
     13Hardware that is still required to complete the platform is a serial console server and a 24-port 1Gbs switch with a 10Gbs uplink.  This will enable to core cluster to be integrated with the research network backbone and support high performance file staging.
