Provide details of spare machines and space available at Subaru for MCS Testing

Following the PFS Servers and Infrastructure WG telecon 2018-07-25, it was noted (see email [PFS-Soft-Subaru:488] Notes – Re: July 25 (Wed) 2PM in Hawaii – Re: Kick-off meeting of PFS servers and infrastructure WG) that:

CDM can provide two spare machines (R710). Right now these are bare configurations with no other disks than 2 SSDs. These can be used as spares of Host #1, #2 or NFS #1. They have only six slots in total (so only 4 free slots). CDM also can allocate some space via NFS and export it for PFS infrastructure. How much space can be available for PFS is TBC. These will be immediately available.

CDM need to provide the PFS team details of the spare machines and of the exportable space available.
