For engineers deploying Dell Unity storage systems — covering Unity XT hardware and Unity VSA, installation and service tasks, system administration, block/file/VMware storage provisioning, FAST Cache, data reduction, and snapshots and replication for data protection.
Master Unity XT and UnityVSA platform concepts, installation and service, system administration, block/file/VMware storage provisioning, data efficiency technologies, and data protection with snapshots and replication.
Module 01
Unity Platform Concepts
›Unity product family — Unity XT hybrid/all-flash arrays: 300/300F, 380/380F, 480/480F, 680F, 880F; Unity VSA virtual storage appliance; use case differentiation
›Unity hardware architecture — dual Storage Processors (SP A and SP B) active-active; back-end SAS/NVMe drive enclosures; DAE (Disk Array Enclosure) expansion; front-end FC/iSCSI/NAS ports
›UnityVSA — deploy as OVF on VMware vSphere; vCenter Server requirements; three license editions (Developer, 4 TB Community, Subscription); VSA resource requirements
›Unisphere for Unity — browser-based HTML5 management GUI; REST API; Unity CLI (uemcli); storage processor isolation and management interfaces
›Connectivity — FC SAN (8/16/32 Gb), iSCSI (1/10/25 GbE), NAS (10/25 GbE); direct-attached and SAN fabric connectivity; multi-initiator multi-path I/O
›Storage pool types — dynamic pools (flexible RAID, 5+1 RAID, mixed tier); traditional pools (RAID-5, RAID-6, RAID-10) with user-defined drives
Module 02
Installation and Service
›Unity XT installation — rack mounting Unity XT chassis; SPS (Standby Power Supply) cabling; backend SAS cabling to DAE expansions; front-end SFP/FC cabling
›Unity XT initial configuration — connect to initial Unisphere wizard via SP management port; set hostnames, DNS, NTP; update software version; license activation
›UnityVSA deployment — download OVF from Dell Support; deploy to vSphere; configure network adapters: management, iSCSI, NFS; launch VSA Unisphere for initial setup
›Service tasks — replace failed drives (SSD/HDD hot-plug); SP replacement procedure; DAE component replacement; firmware update for drives and SP
›Unity service utilities — Unisphere service menu; uemcli commands for hardware status; collect system logs for Dell EMC support; run diagnostics from Unisphere
Module 03
System Administration
›Unisphere for Unity navigation — dashboard: system health, capacity, performance; storage section tree; settings menu; alert and event log management
›User management — local user accounts; Active Directory/LDAP integration; role-based access control (Administrator, StorageAdmin, Operator, VM Administrator)
›Support settings — ESRS (Embedded Service Enabler) registration for proactive support; call home alert configuration; DNS and NTP verification; SSL certificate management
›System settings — SP hostnames; iSCSI network configuration (portals); network interfaces for NAS; jumbo frame MTU settings; VLAN tagging
›Monitoring and alerting — configure email and SNMP alert recipients; set performance threshold alerts; schedule health checks; interpret hardware status indicators
Module 04
Storage Provisioning and Access
›Dynamic and traditional pools — create dynamic pool with Flash and SAS drives; assign RAID type per tier in traditional pool; pool capacity monitoring; pool expansion
›Block storage — create LUNs (thick and thin provisioned); set storage pool, size, SP owner; host access: add initiators to Unity; create host, host group; LUN Masking View
›File storage — create NAS Server with SP affinity; configure file interfaces (NFS, SMB); create file system; export NFS share with access controls; create SMB share with AD integration
›VMware storage — create VMFS datastore for ESXi; NFS datastore for ESXi; Unity vSphere Plugin for Unisphere integration; vVols Protocol Endpoint and Storage Container creation
›Host access — register FC initiators; configure iSCSI portals and CHAP authentication; SMB/NFS file access for Linux/Windows; multi-path I/O (PowerPath, MPIO) host setup
Module 05
Storage Efficiency
›FAST Cache — configure all-flash SSD FAST Cache pool; enable FAST Cache for LUNs and file systems; FAST Cache read/write caching behavior; monitor cache hit rates in Unisphere
›File Level Retention (FLR) — enable FLR on file system; minimum, maximum, and default retention periods; auto-lock mode vs. compliance mode; FLR event log access
›Data Reduction — enable inline deduplication and compression for dynamic pools; view data reduction ratio and space savings; understand data reduction impact on write performance
›FAST VP — automated storage tiering for traditional pools; promotion/demotion schedules; monitoring tier distribution; initial tier allocation policy; manual relocation
›Thin provisioning and space reclamation — thin LUN subscription ratios; monitor over-subscription; space reclamation with Unisphere; zero-page reclamation for VMware vSphere
Module 06
Data Protection and Mobility
›Snapshots — create snapshots for LUNs, file systems, and VMware datastores; consistency groups for multi-volume consistent snapshots; attach snapshot for host access; restore from snapshot
›Snapshot schedules — create daily/weekly/monthly snapshot schedules; retention policy for automatic deletion; monitor snapshot counts and capacity usage
›Synchronous replication — Unity Metro sync replication; configure replication session between two Unity systems; RPO = 0; failover and failback procedures for sync replication
›Replication management — monitor replication session health in Unisphere; alert on replication lag; scheduled/unscheduled sync; reverse replication after site recovery
