Integrating Dell EqualLogic storage solutions with VMware vSphere enhances the management and functionality of your virtual environment by utilizing advanced API interfaces. This comprehensive guide discusses the available methods for integrating Dell storage arrays with VMware vSphere, focusing on the EqualLogic product line.
Integration Approaches
vSphere Client Plug-In
The first method involves using a vCenter Server plug-in to integrate the storage management interface directly into the vSphere Client. This approach varies in strength of integration depending on the storage system. While some devices offer robust interactions, others may experience limitations, particularly when using the vSphere Web Client. This plug-in provides access to specific storage management functionalities directly within the vSphere Client interface, simplifying administration tasks.
Direct Communication via APIs
The second integration method leverages APIs, such as VMware vSphere Storage APIs for Storage Awareness (VASA). These APIs allow storage arrays or specific providers to directly communicate with vCenter, enabling detailed insight into logical units (LUNs) and storage profiles. Another set of APIs, known for storage acceleration and offload capabilities, is VMware vSphere APIs for Array Integration (VAAI), although their use is typically confined to the backend systems.
EqualLogic Integration
EqualLogic was among the first in Dell’s portfolio to implement both integration methods: a vCenter plug-in and a VASA provider. The Host Integration Toolkit (HIT) for vSphere, implemented as a single virtual appliance, consolidates these integration features, providing both management and awareness capabilities.
Considerations and Limitations
When implementing these integrations, it is essential to understand the limitations inherent in VASA, which primarily focuses on retrieving storage information rather than managing it. Consequently, organizations often utilize both integration types to achieve a comprehensive management solution, balancing insights with control capabilities.
For further details on deploying these integrations and enhanced configurations, refer to official Dell EqualLogic Deployment Guides or consult VMware’s Knowledge Base.
These integration methods not only streamline storage management within a virtual environment but also leverage the full potential of Dell EqualLogic arrays, enhancing performance and simplifying administrative workflows. For IT professionals managing complex storage ecosystems, employing both vCenter plug-ins and direct API communications is a best practice. This combined approach leads to a more efficient and responsive virtualized storage framework.
