LDC's IT infrastructure is a comprehensive, autonomous and internally-managed system within the University of Pennsylvania's infrastructure, permitting the modularity and flexibility required to match LDC needs.
- In-house Storage-as-a-Service (SaaS) integrating heterogeneous storage solutions, from DA, to NAS and fibre channel-based SAN. More than 200TB are currently online with the capability to scale up to Petabytes rapidly and transparently.
- Comprehensive backup and disk replication.
- In house Compute-as-a-Service (CaaS) with multitiered service model and physically distributed compute nodes.
- Standard Internet services (e-mail, web, etc.) with more than 300 Gigabit switched ports, a /22 private IP space, a public /24, and public /23 on two separate networks. Two autonomous WiFi networks are provided on the private IP space as well.
- A helpdesk and support service for LDC staff and researchers with real-time monitoring, alarming and trouble ticket processing tools.
