Configuring and Monitoring EMC Celerra (SNMP) Technical Note

Introduction

Microsoft System Center Operations Manager (SCOM) is an end-to-end service-management product that is part of Microsoft System Center Solutions for Dynamic Data Centers. It works seamlessly with Microsoft software and applications, helping organizations increase efficiency while enabling greater control of the IT environment.

EMC® Celerra® offers powerful, multiprotocol network storage through its unified storage platforms. Celerra unified storage systems deliver a single-box block and file solution that offers a centralized point of management for distributed environments, and enables dynamic growth, sharing, and cost-effective management of its multiprotocol file system in addition to providing multiprotocol block access. Its simultaneous support for Network File System (NFS) and Common Internet File System (CIFS) protocols enables Windows and Linux/UNIX clients to share files simultaneously from the same multiprotocol file system. Celerra unified storage systems offer native Fibre Channel for high-bandwidth or latency-sensitive applications and iSCSI for Tier-2 block applications.

By using SCOM’s Simple Network Management Protocol (SNMP) support, IT organizations can monitor Celerra systems directly from SCOM. This document shows you how to monitor Celerra uptime and events by using SCOM.
