...
Servers can run either the latest Windows Server operating system or a Linux-based operating system (RedHat Enterprise Linux [Oracle] or Ubuntu Linux). CIT provides system administration support for Windows and Linux servers, as well as well as maintaining the infrastructure.
Running on a highly available cluster running in two data centers able to withstand loss of an entire datacenter and individual hosts
Server hardware is transparently upgraded every 3 years
OS Licensing
CIT will provide appropriate operating system licensing so that virtual machines can run on any node in the cluster.
...
The first tier (Tier 1 storage has no single point of failure. It has the following characteristics:
Redundant data connections
Mirrored between two storage arrays (in South Hall Data Center and Erwin Data Center) in an active-active configuration (zero data loss on outage of one building)
Configured for off-campus storage array based disaster recovery (Once per day by default, more often if business case allows)
Configured for off-campus backup (Once per day by default, more often if business case allows)
Snapshotting capabilities for rolling back planned upgrades.
Tier 2
The second tier (Tier 2) storage also has no single point of failure. It has the following characteristics:
Redundant data connections
Mirrored between two storage arrays (in South Hall Data Center and Erwin Data Center) in an active-active configuration (zero data loss on outage of one building)
Configured for campus on-site backup (Once per day by default, more often if business case allows)
Snapshotting capabilities for rolling back planned upgrades.
Tier 3
The third tier (Tier 3) storage has a single point of failure and has no backups. This tier is for experimental and developmental purposes. No production server should run on this infrastructure.
Backups of virtual machines
...
CIT has defined five criticality levels for servers:
High Impact/High Threshold of Pain Production System – Affects a high percentage of the community/college if unavailable. Business continuity procedures are difficult.
High Impact/Low Threshold of Pain Production System – Affects a high percentage of the community/college if unavailable. Business continuity procedures are manageable.
Low Impact/High Threshold of Pain Production System – Affects a small percentage of the community/college if unavailable. Business continuity procedures are difficult.
Low Impact/Low Threshold of Pain Production System – Affects a small percentage of the community/college if unavailable. Business continuity procedures are manageable.
Testing/development system – Minimal impact if unavailable
Virtual Machine Operating System Updates & Security
...
CIT will ensure that enough resources are available in the virtual infrastructure to support all running virtual machines. Hardware upgrades to the physical servers in the infrastructure will be performed at a minimum of every three years. CIT will provide N+1 physical servers such that loss of one physical server will not prevent any virtual machines from running.
