Dell PowerMax Operate case studies
Dell PowerMax Operate · Put your knowledge to work in context.
The Dell PowerMax Operate exam validates the day-to-day operational skills needed to run a PowerMax array: understanding its architecture and hardware components, navigating Unisphere for PowerMax and the management interfaces, provisioning storage groups, volumes, and masking views, configuring host connectivity and multipathing, performing SnapVX local snapshots and SRDF remote replication operations, monitoring performance and capacity, handling health alerts and routine maintenance, and troubleshooting basic faults. It suits storage administrators, infrastructure engineers, and data-center operations staff who already work with PowerMax or are moving into a role where they will. The Dell PowerMax Operate case studies are 5 cases and about 3,577 words.
1Cluster Host Sees Four LUNs but Only Two Paths
A two-node Linux cluster needs four 2 TB volumes. You create storage group SG APP PROD with four thin volumes and one masking view MV APP PROD, using initiator group IG APP PROD (both nodes' four HBAs) and existing port group PG FE 01 (four front-end ports).

An 8 TB storage group SG ORACLE PROD is protected by a SnapVX policy that runs every 4 hours and retains 7 days (42 snapshots). The array's 40 TB SRP is at 86% used; snapshot space is 32 TB and rising.

SRDF/A is configured between two PowerMax 2500 arrays for a 12 TB SG PAYMENTS storage group. The RDF group uses two 10 GbE RDF ports over a 35 ms RTT FCIP link.

Capacity review for a PowerMax 2500: SRP PROD has 200 TB usable, 175 TB subscribed, and 25 TB free. Thin volumes account for 150 TB allocated; snapshot usage is 30 TB; compression ratio is 1.6:1; 18 TB of thin volumes have never been written.
