NAS Server and Archive

Duke's NAS is a file storage server used for departments and schools. The NAS allows your stored files to be shared by multiple clients.

You may also use NAS-Archive. This offering is an addition to the existing tiers of storage OIT offers. The NAS-Archive solution is targeted at meeting data needs that can withstand some reduction in performance and uptime with the benefit of a lower cost solution. 

The below chart shows the differences in NAS and NAS-Archive storage options.

Item NAS NAS-Archive
Targeted Storage Almost any network accessible (CIFS or NFS) storage across Duke University Any archive type data that will be written once and accessed minimally and does not require backups.  If read/write times and/or uptime is a critical factor, the standard NAS should be used instead.
Minimum amount  "None".  Current NAS volumes are as small as 10 Gb. 5 TB initial request with increments of 5 TB thereafter.
I/O Requirements Production NAS storage.  10 Gb connections from the NAS to the core with tools to monitor and identify bottlenecks 1 Gb connection with only minimal monitoring.  Data will be maintained on spinning disks and should be accessible at all times, but expectations on time to write and/or retrieve data should be minimal (within reasonable expectations)
Monitoring Multi-level monitoring and alerts that allow for proactive identification of issues and bottlenecks at all levels (network, array, disk, volume, etc.) before they become user impacting issues. Very minimal monitoring and alerts beyond simple up/down, network connectivity, and/or high level capabilities.
Backups Snapshots for file-based recoveries and OIT backup service for Standard and Disaster Recovery options. Same as NAS
Support 24/7 OIT support with 24/7 "gold level" vendor support and monitoring.  Full vendor call home functionality identifies faluts to the vendor's supportteam often prior to actual failures. Minimal up/down availability monitoring.  8/5 vendor support.  As with all OIT supported services, downtime will be minimizied, however, up to 24 hours of downtime may be scheduled periodically to allow for upgrades and/or rebalancing of the storage arrays.
Hardware High level of hardware redundancy built in (controllers, backplanes, power, etc.) to minimize downtime. Minimal hardware redundancy built in (power & RAID disks).
Access Method NFS and/or CIFS NFS and/or CIFS
Cost (Actual and Charged) See pricing See pricing
