File Services For our purposes, I’ll loosely define File Services as storing and sharing File Services For our purposes, I’ll loosely define File Services as storing and sharing files.

File Services - Goals • All Inclusive: everyone is part of File Services • File Services - Goals • All Inclusive: everyone is part of File Services • Consistent: When I want to get something from the finance office, I know what to expect, because it’s the same as my department • Universal Access: from any platform • “Easy to use” • Secure • Reliable

Functional Requirements • Put personal files that can be accessible from any computer on Functional Requirements • Put personal files that can be accessible from any computer on campus (file storage) – diskless Eudora • A place to share files with others (file sharing) – departments – courses – organizations – other collaborations and communities

Functional Requirements (cont. ) • A mechanism to “give” files to others • A Functional Requirements (cont. ) • A mechanism to “give” files to others • A place for web pages

File Servers • NT Server • RAID 5, nightly backups • Scalable architecture Students File Servers • NT Server • RAID 5, nightly backups • Scalable architecture Students A-K (We can easily add another student server, if needed) • Sized for growth (servers all have capacity for more hard disk, memory) Students L-Z • Meaningful names • 3 Year Life Admin Depts Academic Depts

Switching Gears To Web Architecture Switching Gears To Web Architecture

Web Strategy • Started with a single central web server – this is currently Web Strategy • Started with a single central web server – this is currently www. bucknell. edu – running on Unix – Apache server • Migrating to a strategy of supporting web pages within the existing file services

Web Server • Windows NT 4. 0 • Microsoft Internet Information Server 4. 0 Web Server • Windows NT 4. 0 • Microsoft Internet Information Server 4. 0 • Multiple IP Addresses and Host Names • www. facstaff, www. students, www. departments, www. orgs • Allows for scalability - we can easily add one or more additional servers • Will become www. bucknell. edu • Only contains Bucknell’s top level pages

Switching Gears To Building Reliability Switching Gears To Building Reliability

Building Reliability • Programs – “Triage” Students – Automatic System Checks • Includes all Building Reliability • Programs – “Triage” Students – Automatic System Checks • Includes all systems, not just File Services • Documentation, including • • list of servers and services who’s responsible priority/response expectations hours of support

“Triage” Students • 3 Students • On call from 5: 00 pm to 8: “Triage” Students • 3 Students • On call from 5: 00 pm to 8: 00 am, and all weekend • Carry a beeper • Trained to provide a first level diagnosis (triage) when problems are encountered during non-work hours

“Triage” Students - (cont. ) • Perform system checks at 9: 00 pm and “Triage” Students - (cont. ) • Perform system checks at 9: 00 pm and 6: 00 am every day. – send e-mail to themselves – post to a newsgroup – copy a file from each file server – print to lab printers – ping lots of hosts – access servers via Apple. Share – visit web pages on various servers

Automatic System Checks • Had a homegrown system that: – performed checks every two Automatic System Checks • Had a homegrown system that: – performed checks every two minutes • pinged lots of devices • copied a file from each server to exercise netbios – provided an audible alert to operators – sent e-mail to appropriate person when a system didn’t respond – worked most of the time

Automatic System Checks (cont. ) • Recently started using a commercial product – What’s Automatic System Checks (cont. ) • Recently started using a commercial product – What’s Up Gold – Does many of the same things, only better – Much easier to set up – Can also check services, such as NNTP and SMTP – Flexibility in configuring alerts – Support for e-mail, beepers, pagers, and voice

What’s Up - Console • In computer room • Visible to operators • Audible What’s Up - Console • In computer room • Visible to operators • Audible alarm when something is down
