Highlights

• The IBM System Storage® EXP3500 Express supports attachment to the IBM System Storage DS3500 Express external controller, providing a highly available storage system
• Next-generation SAS expansion enclosures
• Supports high bandwidth and random I/O applications with 6 Gbps x4-wide SAS ports
• Support for up to 24.0 TB of SAS physical disk storage (2.0 TB capacity-optimized SAS) in a single enclosure and up to 192.0 TB when fully expanded up to 96 drives
• Leverages enterprise class, engineering, and development to ensure best-of-breed technology and robustness
• High-performance SAS, capacity-optimized SAS hard disk drives and self-encrypting drives (SEDs) intermix support
• Redundant components support continuous access to data for data availability 24/7/365

• EXP3512 and EXP3524 expansion units can be intermixed behind a single DS3500 for optimal data utilization and efficiency
• EXP3512 for offers the highest flexibility with support for a full range of requirements—high capacity and low cost to high-performance critical applications
• EXP3524 is ideal for IOPs-intensive applications and energy efficiency requirements with the highest IOPs/watt and 134 percent improvement in IOPs/U (compared to EXP3000 expansion unit)
• Power supplies designed to meet multiple power efficiency standards
• Uses Storage Bridge Bay (SBB) standard architecture designed for robust system environments

The EXP3512 and EXP3524 expansion units are designed to meet today’s and tomorrow’s demanding data requirements affordably by building on over 30 years of design expertise. IBM’s legacy in enterprise storage systems, with next-generation 6 Gbps SAS drive technology, allows the EXP3500 expansion units to deliver best-of-breed technology, reliability, and performance. With two models available, the EXP3500 expansion units are 2U cabinet-mountable 6 Gbps drive enclosures that are designed to support either a total of twelve 3.5-in. SAS drives (EXP3512) or twenty-four 2.5-in. SAS drives (EXP3524) for optimal flexibility and efficiency. The EXP3500 expansion units can be a key component of a high-performance storage solution. With each external SAS port on the ESM supporting a 6 Gbps x4-wide connection, the EXP3500 can achieve excellent throughput to the host.

With global commerce and 24/7 information available on-demand, businesses require continuous access to information in order to be productive, competitive and ensure customer satisfaction. The EXP3500 expansion units offer the assurance of high availability with redundant power supplies and environmental service modules (ESMs) which ensure that contact with the drives continues even in the rare instance of a component failure. With hot-swappable components, you can remove and replace ESMs, power supplies and drives with minimal or no downtime. The struggle to manage escalating data volumes also will not stop, even in a slow-growth economy. The EXP3500 expansion units, with next-generation 6 Gbps SAS back-end technology, provides organizations with a seamless path to external storage—improving performance, scalability, and low power consumption—all within a small footprint.
