 There are 557 lines in ''/etc/passwd'' at this writing. Assume 25 are system accounts, 25 collaboration accounts (hpc01-hpc25, can VPN, for non Wesleyan faculty/PI, AD accounts), 100 temporary/recyclable class accounts (hpc100-hpc200, can not VPN, local accounts) which then leaves a lifetime user base of roughly 400 user accounts.  Of those, which come and go, 2 to 2 dozen users may be logged in at any time. There are 557 lines in ''/etc/passwd'' at this writing.

-Rstore is a platform for storing research static data. The hope is to move static data off the HPCC and mount it read-only back onto the HPCC login nodes.  440 tb, fully replicated, is provided for this purpose (Supermicro storage boxes using Rsync as replication engine) for HPCC users and other Wesleyan groups.+Rstore is a platform for storing research static data.

 The Data Center has recently been renovated so the HPCC has no more cooling power problems (It used to be in the event of a cooling tower failure, within 3 hours the HPCC would push temps above 85F). No more. We have sufficient rack space (5) and power for expansion. For details on that "live renovation" process visit [[cluster:178|Data Center Renovation]]. It turned out the HPCC was consuming 1/3rd of all electric and cooling capacities.
