Certification Exam (HH0-440) - Hitachi Data Systems

Hitachi - Inspire the Next

Hitachi Data Systems Architect - Performance exam (HH0-440)

This test will verify the successful candidate has knowledge of storage performance concepts, Hitachi storage performance tools and products, standard performance analysis tools, optimal storage design principles and bottleneck analysis and resolution.

Storage performance architects need a knowledge of servers, operating systems, file systems, disk drives, Fibre Channel, host bus adapters, fabric and host, interconnect hardware, applications and virtualization in storage systems. They also need to have a deep understanding of RAID, I/O concepts and storage design principles.

Day-to-day activities include designing data storage configurations for new IT databases and applications. They assess, plan and design storage solutions to meet the business needs of Hitachi Data Systems customers. An architect can technically assess an enterprise infrastructure to create business solutions from a storage perspective. They in turn hand off the design to Implementation Specialists or Storage Managers to execute.

Audience: Hitachi Data Systems and partner consultants, architects and engineers

Requirement: Hitachi Data Systems Certified Professional credential.

To earn the Hitachi Certified Architect, a candidate must pass the Hitachi Data Systems Storage Foundation certification exam in addition to passing this exam.

Passing score: 68%
Test questions: 57
Test duration: 60 minutes; 90 minutes for non-English speaking countries
Cost: US$200 in North America, US$225 outside of North America.
