Primary Storage
We offer primary data storage in quarter-terabyte increments. Our hardware implementation is modular and grows with demand, with approximately 70 terabytes of usable storage currently deployed.
Storage can be accessed over the network in various ways...
from Mac and Windows desktop systems via Windows Filesharing (samba)
from the computational grid via NFS (Network Filesystem)
from hosted servers via iSCSI or NFS
All primary data storage is backed up nightly to our Tivoli Storage Manager backup service. One backup copy is kept onsite for on-demand restores; a second encrypted backup copy is stored offsite for disaster recovery.
Our enterprise-class backup/archive solution is based on IBM’s Tivoli Storage Manager (TSM) software and supports a wide range of client operating systems including MacOS, Windows and Linux.
Features
Retention Policy
Retention policy applies to data that has marked “expired” because it no longer exists on primary storage. Our default policy is to retain backup data for 30 days after it has been deleted from the client. In other words: If you delete data which has been backed up to our TSM server, you have 30 days to change your mind. (Longer retention periods are available on request, however this can increase the overall size of the backup data.)
Archive retention is unlimited, because deletion from primary storage is assumed.
Rates
Backup/archive storage space on our TSM server is available in 1TB increments at $40/TB/month.
This rate includes an encrypted offsite copy for disaster recovery. Note that space utilized is determined on the backup server, not the client. Thus, data occupancy may be greatly reduced by compression. For example, if 10TB of primary storage compresses to 5TB when stored on the TSM server, the storage fee would only be $200/month (5TB * $40/TB/month). There is no additional fee for the offsite copy.
LAN/Desktop Services
We provide comprehensive on-site support for desktop workstations, laptops, printers, and tablets. Services include:
Rates
Our standard rate for cradle-to-grave contract support is $360/device/year.
Non-contract support is available at $80/hour (half-hour minimum).
Hosting Services
In order to meet the complex and varied individual demands of research, academic, and administrative clients, paradIGM offers flexible custom hosting services.
We can deliver turnkey virtual servers for projects with modest disk and memory requirements, and whose software components are fully supported by the Red Hat application stack (e.g. apache, mysql, postgresql). Most web-database applications fall into this category.
For complex projects, we can engineer highly specialized solutions, including the deployment of dedicated data center hardware, hardware-software integration, custom web/database application development, and high-availability failover.
Deployment options include:
Explanation of Rates
Our server hosting rates are calibrated to cover deployment, security, maintenance, monitoring, and troubleshooting. The basic rate is $75/month, adjusted for complexity according to the number of “modules” in the service.
