Monitoring and Management of RAIDs in OpManager

Heterogeneous management tool for storage area networks

ManageEngine® OpManager uses SNMP / CLI / SMI-S/ vendor-specific APIs to discover the RAIDs in your network. Complete set of asset, capacity, performance, and configuration information of the RAID and its components are discovered and represented in the OpManager client.

OpManager provides out-of box reports spanning inventory, performance, and availability as given below

I use OpManager to receive alerts for EVA4400, 6500 of any failures for example Disk LUN issues. My experience so far has been positive.

Asset Management

RAID Assets
  • Up-to-date device summary
  • Administrators can key in details such as device location, vendor details, and technical support info.
  • Comprehensive physical and logical asset details in RAIDs
  • Device level problem report filing and maintenance

Fault Management

RAID Alarms

OpManager periodically polls the devices to check the health, availabiity, and utilization of storage RAIDs. Early indications are provided on hardware/software problems and alarms are generated on drive failures, sensor faults such as Fan Failure, Battery Failure, Power supply failure. SNMP traps from the arrays are also captured and appropriate alarm is generated.

  • Captures Storage Array & Component Status Change Notifications
  • Management functions such as assign owner, annotate, clear, and delete
  • Reports alarms to administrators through email or SMS messages based on customizable rules
  • Escalates unattended alarms to higher ups based on pre-defined rules

Availability Trends

RAID Availability

Availability reports on RAID controllers and its ports show the availability trends, downtime history, MTTR, MTBF, etc

You can generate the reports for various time periods such as today, yesterday, last N days, last week, this month, last month, and between two selected days

Performance Reports

RAID Controller Reports

Performance statistics are computed at periodic intervals and reports generated to provide trend analysis for the storage array components like

  • Storage Array Capacity
  • Storage Array
  • Controller / Storage Processor
  • Virtual Disks
  • Raid Groups
  • Disk Groups
  • Disk Drives
  • Controller Port Statistics

The parameters collected include the following ,

  • Traffic - Read / Write / Total
  • Utilization - Read / Write / Total
  • Bandwidth - Read / Write / Total
  • Throughput - Read / Write / Total
  • Latency - Read / Write
  • Queue Depth
  • Storage array capacity - Total / Configured / Used / Free

You can visually see the utilization of components like LUN volumes and take preventive measures as they reach their peak capacities

Visualization

RAID Map View
  • Topological map shows arrays and their connections to switches and host servers.
  • Link details table shows link name, source, and destination.
  • Color-coded icons depict switch and interconnection status.
  • Drill-down views - Array Sub-map views
