Systems for Email • Multiple UNIX sendmail servers. • Multiple UNIX login servers for interactive users. • Multiple UNIX core servers accessing disk space and servicing Pop and IMAP. • Redundant copies of all disks, power supplies and servers. • Round Robin assignments, load balancing, clustering. • Email service separate from Coursework, Web, Netnews and other UNIX services.
FAS Email Systems Disk Farm ~750 Gig Core Servers (Pop/IMAP) (Local Director) bus Sendmail servers (round robin) nfs Interactive logon servers (round robin)

Preparations Completed • Upgrade of core email servers: Three 600 Mhz Alphas (Digital Unix) using Cisco Local Director to balance load. • Increase of disk space to allow for 50 megabyte default with 100 megabyte available on request. • Installation of the UWash IMAP server.
A Creeping Introduction • Eudora 4.x distributed to all users. • No sweeping formal action to move people to IMAP. If Pine/Eudora-Pop3 works for a user there is no need to change. • “Brown bag” sessions to introduce IMAP features. • Training sessions set up to help users who wish to switch. • Advice from Help Desks and student consulting.
Calendaring in FAS at Harvard • Meeting Maker 5.03 for offices on a voluntary basis. Offices must pay for their own clients. We manage the server. 400 users among 3000 faculty and staff. PalmPilot support. No students. • Harvard College events calendar--student/staff written. Oracle based. Student group local management • Three-tiered classroom scheduler being written to deal with Harvard’s FAS’s local scheduling control issues.
