Highlights

  • Meet growing business needs with a robust and expandable infrastructure designed for non-disruptive expansion to more than 4.3 petabytes (PB) (4,320 terabytes (TB)) storage capacity
  • Gain management versatility with simultaneous file serving and block input/output (I/O) over Ethernet and Fibre Channel (FC) storage area network (SAN) infrastructures
  • Ensure that critical workloads get priority service with FlexShare
  • Enable continuous operations with support for application-level recovery in minutes, not hours
  • Deliver consistent high performance for mission-critical applications in storage and data protection.

In an increasingly demanding and competitive business landscape, effective data management is essential to the success of your business. Employees, partners and customers need access to up-to-date information to work productively, make timely decisions and meet business goals. IT is under pressure to deliver more storage capacity at higher levels of service. Yet critical resources, including staffing, budget, power, cooling and floor space, are often constrained. Storage efficiency becomes the key to keeping pace with this growing environment.

These demands call for enterprise-class storage systems with the flexibility to support changing IT requirements, accommodate continuous data growth, satisfy application-level service requirements of network attached storage (NAS) environments and support SAN infrastructures – all at a low overall cost.

Feature Benefits
