Fermi currently supports an xroot service consisting of 33 Sun Thumper/Thor class servers plus 12 Dell R610/620 class servers. Fermi also supports an NFS service consisting of four Sun Thor class servers. One additional Thumper class server is used by LSST. The Sun servers range in age from 4 to 8 years. The oldest Dell systems are three years old.
Fermi is looking to purchase two storage building blocks with ~640 TB TB each year with 1 with ~1/2 to accommodate new incoming data, and the other 1remaining ~1/2 to allow for aged equipment retirement/repurposing. The following proposal resulted from a meeting held 2/18/2015 with Shirley, Yemi, Lance, Wilko, Richard, and Tom.

Two new Dell R620 systems (~640 TB) were purchased summer 2014 and are in the process of being commissioned.
Two additional Dell systems (~640 TB) are anticipated for the summer 2015. The expected use of these servers will be to increase the xroot GPFS pool.
