Dell 0WT92N Equallogic iSCSI Storage Controller

Product Description

The Dell 0WT92N is an iSCSI Storage Controller, a specialized hardware component integral to Dell's Equallogic line of storage arrays. Its primary function is to manage the storage resources within the array and present them as block-level devices to servers over standard Ethernet networks using the iSCSI protocol. This approach allows organizations to build Storage Area Networks (SANs) using cost-effective and widely adopted IP infrastructure, offering a compelling alternative to Fibre Channel SANs. This controller is designed to handle the complexities of iSCSI communication, including data encapsulation, error checking, and session management, ensuring reliable and high-performance data transfer between servers and the storage array. It typically features multiple high-speed Ethernet ports (often 1GbE or 10GbE) to provide sufficient bandwidth and redundancy for storage traffic. The controller also plays a crucial role in implementing advanced Equallogic features such as data replication, snapshots, thin provisioning, and automated load balancing across the array's disks. As a core component of the Equallogic system, the 0WT92N controller is engineered for high availability and performance. In many Equallogic configurations, dual controllers are used to provide redundancy; if one controller fails, the other can seamlessly take over its workload, ensuring continuous access to data. This makes the Dell 0WT92N a critical element for businesses seeking scalable, reliable, and efficient storage solutions managed over an IP network.
