File Hosting

File Server Hosting allows your UF organization to lease fully managed file server resources (accessible via SMB or NFS) from UFIT's infrastructure. UFIT manages all the elements of purchasing and maintaining hardware resources and overall administration of servers. Your file server will live in UF's private file server cloud which may include NAS appliance failover across multiple physical locations to prevent downtime due to hardware failure or maintenance.

UFIT Provides

UFIT provides all compute and network hardware and infrastructure for the file server appliance. UFIT provisions your file space and works with your IT staff to assign administrative privileges and permit access via network ACLs and file share permissions.

Customer Provides

You will assign one or more of your IT team to fulfill the role of file share administrator. This role will manage snapshot restores, file-system security privileges, drive mappings, and other client-side configurations for users.

Used Terms Definitions

Term Definition/Use Cases
Performance Tier Business/department critical shared files, high throughput and performance with frequent access.
Capacity Tier Default storage tier. Front office fileshares, large datasets, infrequent or occasional access.
Basic Tier Lowest cost durable storage. Limited performance, for files that are rarely accessed but need to be available online.
Size Currently defined in multiples of 250GB for Performance Tier and 1TB for Basic and Capacity Tiers. Larger file share capacities may be available by request and require approval.
RAID Protection Provides industry standard Redundant Array of Independent Disks (RAID) protection via Parity and other redundancy mechanisms.
Mirroring Provides real-time near 0 RPO synchronous mirroring of data to other site (SSRB <--> UFDC), not user configurable.
High Availability Dual site provides controller-level redundancy and data availability cross-site in case of localized site disasters/outages; single site provides controller-level redundancy only.
Snapshot Point in time copy of a storage offering, saved for some time for potential resotration of the storage to the time the snapshot was taken. Snapshots exist on the primary storage system, so failures destroying primary data may affect snapshots too. Contrast with 'backup'.
Snapshot Schedules See "Snapshot Schedule Options" table below.
Nested Shares Ability for a folder/directory within a share to also be shared via another name, usually with different connection permissions.
Nested Quotas Ability to assign a quota to a specific subdirectory within an existing larger quota.
Access Protocols File (SMB, NFS).
Encryption at Rest Industry-standard cryptographic ciphers encrypt your data before writing it to persistent storage. Thus, if a storage drive is lost or stolen, the data stored on it cannot be read. Required by many regulatory standards.
Encryption in Transit for Client Access Provides the ability to encrypt data between file server and client. Currently only available for SMB and requires the client to support SMB3 with encryption. Additional client configuration may be required to enforce this setting. Enabling this feature may prevent unsupported clients from connecting to the share. Create a Service Request (SR) for assistance in enabling this feature.
Average IOPS Per TB A measure of file system performance. Average Input/Output Operations per Second per TB.
Cost Cost per TB per Month.
Replication Copying a share/export from the primary site to a secondary site in the same local region. Available sites are UFDC and SSRB.
Limited Service failover (site disaster) for Basic Tier In the event of a disaster of the primary site, UFIT Storage Team will execute a service failover to the standby site. Only those file shares and exports configured for replication will be available. Non-replicated file shares and exports will remain unavailable. The following conditions and Service Level Expectations (SLEs) apply:
  • Recovery Time Objective (RTO) 1 hr: File Services may be available up to one hour after service failure occurs.
  • Recovery Point Objective (RPO) 1 hr: Up to an hour of changes to your data may be lost in the event of a service failover.
Limited Service failover (site disaster) for Performance and Capacity Tiers The following conditions and Service Level Expectations (SLEs) apply:
  • Recovery Time Objective (RTO) 0: Shares/exports configured for replication are immediately available as READ-ONLY at the secondary site.
  • Recovery Point Objective (RPO) 8 hrs: Up to 8 hours of changes to your data may be lost in the event of a primary site failure. This varies between 2 and 8 hours based upon the configured replication schedule.
  • The export mountpoints or file share UNCs change between primary and secondary sites. Changing this is disruptive to client access.
For suggestions on minimizing impact to clients, refer to the Advanced Client-side Configuration Recommendations section below.
Encryption in transit for Replication This refers to the availability and use of industry standard encryption in the replication of data from the primary site to a secondary site for shares configured for replication.
Backup A data copy stored in a physically independent system. Even catastrophic failure of the primary system does not damage the "backup" copy. (Cold copy, takes time to be restored to production system in event of disaster or outage). Due to performance constraints we cannot offer this service on the Basic Tier.
Archive Data which is intended to be stored for "a long time" in the view of the customer, seldom read, seldom re-written. (vaulted, cold copy, takes longer than backup service to recover, reconstitute and recover to production systems). Due to performance constraints we cannot offer this service on the Basic Tier.

Snapshot Schedule Options (snapshots are taken between 11:55 PM and 5:00 AM (staggered during this period)).

If users define snapshots for the share, they can perform file-level restores via Windows Previous Versions or Linux equivalent functionality.

Should you require longer-term data protection or independent data backups, UFIT staff can assist you in configuring and maintaining a TSM backup service.

Advanced Client-side Configuration Recommendations

For Performance and Capacity shares: to minimize client disruption during File Services failover in the event of disaster, Windows users may ask the UFIT Microsoft Core Team to create a DFS namespace for the share. Then, they may configure the primary site UNC and secondary site UNC as weighted paths in DFS and access their share in this manner. Similarly, Linux users may configure the Linux automount client to fail-over between the primary site and secondary site paths. Fileshare access remains read-only at the secondary site. To restore read-write access to your share/export at the secondary site, create a service request ticket with the storage team.
