The IBM DCS3700 storage system is a mid-tier storage system from IBM with an enhanced version called the DCS3700+. The DCS3700 offering is targeted for usage with System x, BladeCenter, and Power systems. The DCS3700 can scale from a single module 60 drive system to 180 disks (360 for the DCS3700+). The DCS3700 is the turbo model of the DS3500 in the 60 drive package sourced from NetApp Engenio.
Competitive multi-platform distributed storage hardware systems include alternatives such as EMC’s VNX series, Hitachi Data System (HDS) G-Series, and Hewlett Packard’s (HP) StoreVirtual and MSA series.
The DCS3700 Express storage system represents the continuation of the hardware evolution of the systems developed by NetApp Engenio and offered by IBM in their mid-range lineup. There are a variety of packaging options using the modular controller. The DCS3700 provides advanced features that have evolved over time to provide high-value capabilities to customers. As a system that combines performance with advanced features, the DCS3700 meets a wide-range of demands in the market for open systems. The flexibility of SAN attachment for both Fibre Channel and iSCSI interfaces and the 12 Gb/s SAS host connection allows the DCS3700 to be used in multiple environments that cover many different customer needs.
The DCS3700+ model or DCS3700 with Performance Modules has “performance modules” added which include the ability to install more cache, more host interfaces, and additional disk drives.
