Storage Performance Survey
The first step to developing quality storage solutions is to perform a
discovery evaluation of your current storage performance, data
availability, and future storage needs. Engineers can, with the assis-
tance of staff, perform and execute rigorous site surveys to develop
comprehensive statements regarding current and future data man-
agement requirements. Then the requirements must be mapped
against the business mission or objectives. Storage performance sur-
veys may include
 % Written assessment of the current information technology (IT)
storage infrastructure
 % Network and data flow diagrams
 % Storage use and optimization analysis

Storage Architecture and Design
The key to powerful networked storage design is in the quality of the
design and the response to your requirements. Well-organized
knowledge bases are necessary to design enterprise-class informa-
tion and storage infrastructures. Talented, experienced storage engi-
neers will provide custom data management solutions to meet broad
continuums of challenges and deliverables that should be supported
by detailed, documented strategies, including diagrams and imple-
mentation plans for data management. When appropriate, cost/
benefit plans showing payback periods and returns on investment,
including optional lease analyses for all proposed products and ser-
vices, can be requested. Storage architecture and design planning
should include
 % Written recommendations for the storage infrastructure
 % Complete design specifications
 % Installation and integration
Whether you hire certified engineers through consultancy or des-
ignate in-house engineering teams to implement and configure your
SAN, you will need to have them do the following:
 % Install the hardware load.
 % Configure software for all backups.
 % Archive.
 % Perform media management.
 % Provide off-site vaulting, if necessary.
 % Implement verification and testing of backups, archivals, and
restores.
 % Develop operating policies and procedures.
 % Recommend changes where appropriate.
 % Provide detailed information on installation and integration,
implementation, storage management software installation,

switches, hub and adapter integration, redundant arrays of
independent disks (RAID) reconfigurations, server consolidation,
and so on.
These solutions link multiple and disparate storage systems and
servers over secure high-speed storage networks dedicated to data
management. Integration of these solutions enables storage effi-
ciency across tape libraries and disk arrays with optimal shared
resource pooling. These solutions contribute to
 % Improved data availability
 % Decreased administrative complexity and costs
 % Improved asset utilization
 % Reduced downtime
 % Point solutions (backup and recovery solutions, archival systems,
automated storage management data environments)
 % SAN-ready architecture (implements storage infrastructure
components that enable you to take advantage of new
technologies and scalability features as you choose)
 % True SANs (fully networked Fibre-Channel-based SAN with
maximum scalability and advanced data management capability,
the most powerful storage infrastructure for the greatest
operational cost savings)
 % Client site outsourcing (proactive on-site storage systems
management)
