Enterprise Storage (SAN/NAS/S3)
There are several storage options available to faculty and staff. All options provide high availability and are scalable but the features of each vary along with how they are billed. See the Comparison Table below to select the option that best fits your needs.
Types of Storage Access
- Storage Area Network (SAN) - Access by block-level devices via fiber channel infrastructure or iSCSI. The SAN is a network that provides access to consolidated, block-level data storage. SANs are primarily used to enhance storage devices, such as disk arrays, and tape libraries accessible to servers so that the devices appear to the operating system as locally attached devices.
- Network Attached Storage (NAS) - File-Level Access via NFS and CIFS. The NAS is a file-level (POSIX file system) connected to a computer network providing data access to a heterogeneous group of clients as a mountable network file share.
- S3 Object Storage (On-prem and Wasabi Cloud) - Object storage is a technology that manages data as objects. All data is stored in one large repository which may be distributed across multiple physical storage devices, instead of being divided into files or folders.
