Dell DEE-1111: The Retired Expert PowerMax and VMAX All Flash Exam

Dell DEE-1111 was the Expert - PowerMax and VMAX All Flash Solutions exam. Dell retired it on February 2, 2024 and its retirement notice did not name a direct replacement. This page therefore preserves the historical expert scope—performance analysis, security, multi-site SRDF, SRDF/Metro, and non-disruptive migration—without presenting the exam as currently available.

The skills themselves remain relevant to modern Dell PowerMax environments. Current learners can map portions of the old expert blueprint to D-PVM-OE-01 PowerMax Operate and D-PVM-DS-01 PowerMax Design, but those exams are not described here as direct successors. They represent current, skill-aligned destinations in the PowerMax subject area.

DEE-1111 was intentionally advanced. Dell expected significant hands-on experience and used both knowledge questions and performance-based simulations. The historical blueprint is most useful for experienced administrators and architects who want to understand the depth Dell once expected at expert level: not just how to configure a feature, but how to analyze behavior under load, secure management and data paths, and operate complex replication or migration during fault conditions.

Performance analysis began with workload characterization and array architecture

A large portion of DEE-1111 focused on performance. Candidates needed to relate I/O operations to PowerMax and VMAX architecture, characterize workloads, and understand how metrics interact rather than relying on one utilization number. The historical objectives explicitly referenced workload profiles and Little’s Law, signaling that queue depth, response time, and throughput had to be interpreted together.

A useful expert workflow starts with the application complaint and time window, then checks host demand, front-end behavior, cache, backend activity, service levels, and protection operations. Performance evidence should tell a coherent story. If latency increases without corresponding array load, the bottleneck may be outside the array; if a replication or copy operation aligns with the change, protection workload may be relevant.

A baseline is essential before performance can be called abnormal. Record typical IOPS, bandwidth, response time, read/write mix, block size, cache behavior, and service-level behavior during representative business periods. Little’s Law becomes useful because it links outstanding work, throughput, and response time; it helps explain why queues grow as a system approaches a constrained resource even when raw utilization does not look catastrophic.

Front-end, cache, and backend metrics must be correlated rather than viewed in isolation

Host connectivity is part of PowerMax performance, so understanding Fibre Channel storage networking and multipathing helps when diagnosing uneven path use, queueing, or a failed link. A storage array can appear healthy while one host path is saturated or while the multipath policy sends traffic through a reduced set of connections.

Cache and backend analysis require similar discipline. High cache utilization can be normal under one workload and problematic under another. Backend pressure may reflect drive activity, rebuilds, or data movement. The expert task is to identify which metric is causally related to the observed response time and to avoid “fixes” that merely move the bottleneck.

Security combined data protection with administrative control

The legacy exam included data-at-rest encryption, user authentication, role-based permissions, and host-based access controls. The general principles of encryption help separate confidentiality of stored data from the identity and authorization controls that govern who can configure or access the array.

Expert administration also requires change control. Limit privileged roles, protect management interfaces, review audit records, and understand how security configuration affects operations. A secure array is not one where only the media is encrypted; the control plane, host access, credentials, and recovery procedures must also resist unauthorized change.

Separate operational roles where possible. A storage administrator who provisions capacity does not necessarily need authority to alter every security policy or replication target, and service accounts should have only the permissions required by their automation. Expert security design considers the blast radius of a stolen credential and builds controls so one account cannot silently change host access, disable protection, and erase audit evidence.

Multi-site SRDF required understanding topology and failure-state operations

DEE-1111 tested concurrent and cascaded SRDF, R22 devices, SRDF/Star, synchronous and asynchronous consistency, and operations under normal and fault conditions. These technologies create multiple copies and paths, but their value depends on knowing which site has authoritative data and how consistency is maintained when links or sites fail.

A disaster-recovery plan gives these topologies business meaning. Map each site, replication mode, and failure domain to the application’s recovery objectives. Then rehearse loss of a link, loss of a site, and re-establishment after recovery. Expert knowledge is the ability to predict data state and safe next action before issuing a command.

Expert practice should include planned and unplanned state transitions. Simulate a remote-link interruption, a target-site outage, a recovery-site promotion, and the later resynchronization of data. At each stage, write down which devices are writable, which copy is authoritative, whether consistency is preserved, and what host action is required. This prevents a replication diagram from becoming disconnected from actual application behavior during an incident.

SRDF/Metro introduced active access and Smart DR considerations

The old blueprint separately covered SRDF/Metro, device access operations, and Smart DR. Metro designs can provide active access across sites, but that changes how host paths, witness decisions, and failure handling are reasoned about. A site pair that is healthy during normal operation must still have deterministic behavior when connectivity becomes asymmetric or a component disappears.

Study the control and data paths separately. Determine what hosts can access, which side is preferred under different conditions, and how recovery relationships interact with Metro behavior. This avoids treating “active-active” as a guarantee that every failure is automatically harmless.

Non-disruptive migration was a controlled state transition, not a copy job

DEE-1111 included both non-disruptive migration and Metro-based migration workflows through Unisphere and SYMCLI. The expert skill was understanding prerequisites, host visibility, synchronization, cutover state, and rollback options well enough to move production storage while controlling service impact.

Migration planning should document the source and target, supported paths, host requirements, protection relationships, maintenance boundaries, and acceptance tests. After cutover, verify not only that devices are visible but that application I/O, multipathing, performance, and protection behave as expected. A technically completed migration can still be an operational failure if validation is incomplete.

Performance must be watched throughout a migration as well. Background copying can consume array, host, and fabric resources even when application access remains online. Establish acceptable latency and throughput thresholds before the move, monitor them during synchronization and cutover, and know when to pause or reschedule work. “Non-disruptive” describes service intent, not permission to ignore workload impact.

Unisphere and SYMCLI were complementary operational tools

The historical exam required candidates to work with both Unisphere for PowerMax and SYMCLI. Expert-level preparation should treat them as two interfaces to the same underlying state, not as separate products to memorize. A graphical workflow and a command-line workflow should produce consistent storage, replication, and migration relationships.

The current PowerMax Operate scope continues this operational emphasis with Unisphere 10 and Solutions Enabler 10. Learners revisiting DEE-1111 should update command syntax and product versions through current documentation while preserving the deeper skill of interpreting state and choosing safe operations.

Performance-based simulations rewarded field experience and verification habits

DEE-1111 had a simulation component in addition to knowledge questions. That format meant a candidate could not rely only on recognizing terminology. They needed to navigate tools, interpret output, and complete tasks under realistic constraints. Even though the exam is retired, simulation-style practice remains one of the best ways to build PowerMax competence.

Create labs around real incidents: a host with degraded pathing, an unexpected latency increase, an SRDF relationship in a non-normal state, a permission problem, or a migration that has not reached the expected phase. Require yourself to collect evidence before changing anything and to document the post-change state.

Time-box those labs and require a final explanation of root cause and risk. Expert competence is not only reaching a working state; it is reaching it without creating a second problem elsewhere in the array or replication topology.

Use the retired expert blueprint to deepen current PowerMax skills, not to recreate an obsolete exam

Current PowerMax learners should start from the live PowerMax Design and PowerMax Operate objectives, then use DEE-1111 selectively for deeper practice in performance, security, SRDF, and migration. The older exam referenced PowerMax OS 5978, Unisphere 9.2, and Solutions Enabler 9.1, so version-specific screens and commands must be updated.

The enduring standard is expert reasoning: characterize the workload, understand the array and path architecture, predict the state transition, protect data and control access, and verify every recovery or migration operation. That is the part of DEE-1111 worth preserving after retirement.

Also compare the old expert depth with the current role-based structure. Modern design and operate exams separate architecture decisions from day-to-day administration, while DEE-1111 combined several advanced specialties into one expert assessment. A useful learning plan can therefore use the current exams for supported products and workflows, then borrow selected DEE-1111 scenarios to add complexity: multi-site failure handling, performance diagnosis under protection load, and migrations with strict service objectives.
