Application Hosting - Storage and Space Management
This is hardware and software for the storage of customer data and applications. SDC storage Services provide SDC customers with the ability to utilize and allocate appropriate storage type based on their predetermined business classification and requirements. Through the classification of storage tiers, customers will be able to determine levels of storage performance which best meets their price and availability requirements. Storage tiers are based on connectivity, redundancy, availability, performance, and scalability.
- Tier 1 (Disk): Highest availability with fastest performance (mainframe and databases)
- Tier 2 (Disk): High availability with fast performance (databases and file servers)
- Tier 3 (Disk): high availability with average performance (file servers and backup/archive)
- Tier 4 (Tape): Moderate availability with average performance (backup/archive)
- Tier 5 (Offsite): Available within hours or days (archive/disaster recovery)
There are several types of storage that are provided through the SDC:
Storage Area Network (SAN) - storage devices such as disk array controllers, tape libraries and CD arrays to attached to servers in such a way that to the operating system the devices appear as locally attached devices.
Nearline storage - storage systems that manage discrete volumes, such as tape cartridges, that must be retrieved and staged by mechanical means in order to be accessed by the user. The process is not instantaneous, but only requires a few seconds. It is a compromise between online storage (constant, very rapid access to data) and offline storage (infrequent access for backup purposes or long-term storage).
Offline storage - storage systems that require an operator to physically insert the media into a drive before it can be accessed.

- Consult with vendor technical support staff to escalate issues that cannot be resolved internally
- Notify customers of requested customer and SDC upgrades and changes
- Patch and upgrade storage management products
- Support and maintain SAN and Automated Tape Library (ATL) including associated hardware, software, and micro-code
- Manage physical media used for storage, including definition of media rotation requirements, labeling procedures, tape-handling procedures, off-site storage rotation, and media destruction
- Develop storage usage policies specific to customer business
- Configure storage devices; allocate raw storage; define and configure logical volumes, define SAN zones; and establish security on new volumes
- Plan storage capacity changes based on historical usage patterns and customer needs projections
[1] SDC policy on supported software versions will be developed at a later time

| Customer Responsibilities |
|
- Determine storage requirements in terms of volume capacity and appropriate storage tier
- Define data security, storage, and backup and reorganization requirements
- Monitor rate of consumption of storage media so that need for increased capacity does not become an emergency
- Provide estimates of resource utilization and expected growth in terms of Gb of disk space, and quantity of tape cartridges
- Perform impact analysis of proposed changes in storage media or storage management products on the customer’s applications and end-user commitments
- Test new and upgraded capabilities prior to general release to customer users
- Coordinate schedules of upgrades and product releases so that important customer activities (e.g., application rollouts, application upgrades, training sessions or live service) are not affected by the changes
