Disaster Scenarios: Due to the nature of the services provided by AD Domain Administrators, the three typical disaster scenarios (loss of facility <30 days, power outage <72 hours, and university technology infrastructure outage <30 days) are not specific enough to adequately explain workaround procedures as AD Domain Administrators works out of 3 server facilities and have UPS/backup generator power, and the infrastructure is very tightly coupled with OIT’s technology infrastructure.
Therefore it was split into 15 scenarios:
- Loss of Physical Access to Campus: Not Affected
- Campus Power Outage: Server Infrastructure unaffected, but on-campus client machines and labs would be unavailable.
- Campus Network Outage Week+: Staff can likely log into workstations and laptops using cached credentials and work on local data; sneaker net data that users need that resides on servers. Without network access, the usefulness of the lab computers and similar would be extremely limited.
- Poe – Total Loss: Not Affected
- Poe – Facility Infrastructure Outage <72 hours: Not Affected
- Poe – Facility Infrastructure Outage 72+ hours: Not Affected
- EB2 – Total Loss: Not Affected
- EB2 – Facility Infrastructure Outage <72 hours: Not Affected
- EB2 – Facility Infrastructure Outage 72+ hours: Not Affected
- DC1 – Total Loss
- DC1 – Facility Infrastructure Outage <72 hours
- DC1 – Facility Infrastructure Outage 72+ hours
- DC2 – Total Loss
- DC2 – Facility Infrastructure Outage <72 hours
- DC2 – Facility Infrastructure Outage 72+ hours
Out of band access (ILOM, DRAC, Cyclades) will be used for hardware management in the event of a loss of physical access to campus.
- AIM will be used for Instant Messaging in the event of a loss of Jabber services.
- Gmail will be used for Email in the event of a loss of NCSU-provided mail services.
- Ventrilo (running on a VM in VMware) is a free (up to 8 people) voice chat server that will be used for meetings/discussion in the event of a loss of physical access to campus.
- SAN connectivity exists only in DC1, DC2, and Poe.
- References of things “going to tape” implies going from the server, to the VTL in DC2, and then to the tape library in MCNC.
- All instances referring to “Network” implies DNS/DHCP as well.
