MDM cluster component layouts
This topic provides examples of layouts for MDM components in a PowerFlex appliance with two to five cabinets.
The Metadata Manager (MDM) cluster contains the following components:
- Primary MDM 1
- Secondary MDM 2 and 3
- Tiebreaker 1 and 2
When a PowerFlex appliance contains multiple cabinets, distribute the MDM components to maximize resiliency.
Distribute the primary MDM, secondary MDMs, and tiebreakers across physical cabinets and access switch pairs to ensure maximum availability of the cluster. When introducing new or standby MDM components into the cluster, make sure you adhere to the MDM redistribution methodology and select your hosts appropriately, so the cluster remains properly distributed across the physical cabinets and access switch pairs.
The following illustrations provide examples of MDM component layouts for two to five cabinets:
