Data storage is an important aspect of every business. In our data-driven world, a sound storage concept along with a backup and disaster recovery plan is essential. How do you monitor these critical parts of your IT infrastructure? If you rely on Dell EqualLogic SAN (Storage Area Network) arrays for storage, you're in for a treat: PRTG Network Monitor 16.2.24 comes with three new sensor types for EqualLogic monitoring. Whether you want to know what's going on with your logical disks, your physical discs, or the health of your storage array members—you now can easily gather the desired information with three brand-new dedicated sensor types.


SNMP Dell EqualLogic Logical Disk Sensor

To help you keep an eye on the logical volumes of your Dell EqualLogic storage system via SNMP (Simple Network Management Protocol), the SNMP Dell EqualLogic Logical Disk sensor provides the following values:

  • Availability,
  • Average read/write latency,
  • Number of connections,
  • Amount of read/written data,
  • Operational status, and
  • Number of IOPS (Input/Output operations per second).

SNMP Dell EqualLogic Physical Disk Sensor

In addition to knowing what's going on with your logical volumes, it's essential to keep an eye on the status of your physical disks.  Here the SNMP Dell EqualLogic Physical Disk sensor comes into play by offering the following information:

  • Disk status,
  • Bytes read/written,
  • Failed transfers, and
  • Health status of disk.

SNMP Dell EqualLogic Member Health Sensor

To complement monitoring your logical and physical disks, the SNMP Dell EqualLogic Member Health sensor provides you with everything you need to know about the health of your array members:

  • Member status,
  • Cooling power of the fan module in rpm (rotations per minute),
  • Power supply status of cooling system,
  • Temperature of the backplane,
  • Temperature measured by temperature control module,
  • System temperature,
  • Member health status,
  • RAID status,
  • Average read/write latency in milliseconds or as percentage of the largest value,
  • Free storage capacity,
  • Amount of data handled per second, and
  • Number of spare drives available.

Please note: These sensor types are currently in beta status, so please send us your feedback! For more information on these sensor types, please also have a look the corresponding pages of the PRTG manual:
