Description: Dell EqualLogic volume balancer MIB for configuring and monitoring automatic workload rebalancing across storage members.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is EQLVOLBALANCER-MIB?

EQLVOLBALANCER-MIB is Dell EqualLogic's proprietary MIB for the volume balancer feature, which automatically redistributes volume "slices" across storage pool members to balance load and capacity. It exposes configuration for cost calculation frequency and rollup timing, along with tables tracking per-volume-slice cost over time and daily aggregated volume costs. Its monitoring role is performance-oriented: administrators can track volume slice cost trends per array member (eqlvolbalancerVolumeSliceCostPsaId) to see how the balancer is redistributing load, and use daily cost data to identify volumes causing hotspots or imbalance across the storage pool. It operates within the broader EqualLogic array/pool architecture, depending on the underlying storage pool and volume identification scheme shared with other EqualLogic MIBs. It is typically deployed in multi-member Dell EqualLogic PS Series storage pools where automatic load balancing across arrays is enabled. Engineers can download the EQLVOLBALANCER-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in EQLVOLBALANCER-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

  • Dell EqualLogic PS Series storage arrays (multi-member pools)

Monitoring Examples

Polling eqlvolbalancerVolumeSliceCostTable for eqlvolbalancerVolumeSliceCostCost per eqlvolbalancerVolumeSliceCostVolumeId and eqlvolbalancerVolumeSliceCostPsaId reveals which volumes are generating high load-balancing cost on a given array member, and eqlvolbalancerVolumeSliceCostStatus indicates whether that cost calculation is current or stale. Reviewing eqlvolbalancerDailyVolumeCostTable by eqlvolbalancerDailyVolumeCostDay shows longer-term trends, helping an admin decide if a volume should be manually pinned to a specific pool member instead of relying on automatic rebalancing.

What Can Be Monitored

  • per-volume-slice cost
  • daily aggregated volume cost
  • cost calculation frequency/rollup timing
  • cost calculation status (current/stale)
