Performance, Capacity, and Scaling | Latency, IOPS, Bandwidth, capacity and scaling | Scale out architecture - addition control nodes to manage capacity and provide greater performance. FC and IP attached external storage. NVMe over Fabric hardware support. | Different models to meet performance needs - each limited by DRAM cache. No industry standard storage performance numbers. No NVMe over Fabric plans disclosed. | Scale with adding controller cards. Not a true scale out system. No industry stg perf numbers. Does have NVMe. | End-to-End NVMe. Scale out to 8 controller pairs in block mode. Block mode converts blocks to files. | Large scale storage system with virtualization feature. Scale with addition of up to 8 controller cards. No direction on NVMe support. |
Economics – including data reduction & evergreen | Economics - This includes data reduction effect – compaction, compression, deduplication as well as value from simplicity. | Data reduction - inline dedupe & compression with no impact with internal storage. Data reduction for external storage. Controller upgrade program. | No data reduction or thin provisioning. Not part of future proof program. Complexity of system requires specially trained administrators. | Future proof program - no controller replacement. Data reduction with add-in card. Expensive add-on software. | NextCredit program for evergreen. Inline data reduction does have some performance impact. | Data reduction in FMDs and with controller software for external storage. No evergreen program. |
Advanced Features | Additional functional capabilities transparent migration, volume passthru, and including data protection (sync & async), snapshots, business continuity, tiering to cloud | Transparent migration and passthru access. Large suite of data protection functions. HyperSwap business continuity. Transparent Cloud Tiering. Easy Tier for other classes of storage. | Must add RecoverPoint for snapshot. No encyption. No internal cloud tiering with system. | Limited set of virtualized external storage systems. Extensive VMAX features. No internal cloud tiering. | Direct backup to FAS. FabricPool tiering to cloud & object storage: LUNs and snapshots. Large set of features but most are added cost. Limited set of systems that can be virtualized. | Transparent migration and passthru LUNs. No cloud tiering included in system. GAD for business continuity. |
Management and integration | Centralized management for virtualized systems. Incorporated with solutions such as VMware VAAI, VASA, SRM, etc. and MS ODX | Common management and advanced features across external and internal storage. Integration with VMware and Hyper-V and other major applications. | Complex system with very complex management. Very limited integration with other software. | Very complex system. Integration with major applications and Dell EMC data protection. Also VMware, Hyper-V for VMs and management. | Cluster mode is complex. Major application and VMware, MS Hyper-V integration | Complex system with complex management. Does have integration with major applications and VMware, MS Hyper-V. |
Special capabilities | Unified would be an example of a special function. | Over 440 external systems virtualized. Storage Insights predictive analytics and SRM. System in wide usage. | Distance extension. | Virtualization is complicated and rarely used by customers. eNAS feature is clumsy and not in use. | True unified block and file. Limited virtualization with FlexArray feature. ActiveIQ storage analytics. | NAS is an internal bolt-on design. |
