Mô tả
THÔNG TIN NỔI BẬT
| Data progression | Intelligent auto-tiering (both physical and RAID tiers) tunes your environment for maximum performance and cost savings based on real-time data usage |
| Dynamic efficiency | Buy fewer drives to meet your application needs with intelligent compression and deduplication for SSDs or HDDs, pervasive thin methods, space-efficient snapshots, disk optimization and more |
| Live Volume | Now includes auto-failover for built-in protection against unplanned outages and disasters ─ move live data seamlessly among arrays with zero workload downtime |
| Dell Storage Manager | “Single pane of glass” multisystem monitoring and control, enterprise chargeback and cross-platform replication between PS Series and SC Series arrays |
| Other | Data-at-rest encryption, synchronous/asynchronous replication, FC or iSCSI network connections, Support Assist |

| Maximum raw capacity (SAN) | 1PB per array (SSD or HDD), more in federated systems* |
| Maximum raw capacity (NAS) | 1PB per array with optional FS8600 6PB in single namespace (with FS8600 and multiple SC4020 arrays) |
| Storage media | SAS and NL-SAS drives; different drive types, transfer rates and rotational speeds can be mixed in the same system • SSD: write-intensive, read-intensive (SLC, MLC and TLC formats) • HDD: 15K, 10K, 7.2K RPM |
| Front-end network protocols | FC, iSCSI (supports simultaneous multiprotocol) |
| Max 16Gb FC ports | 4 per array (SFP+) |
| Max 8Gb/4Gb FC ports | 8 per array (SFP+) |
| Max 10Gb iSCSI ports | 6 total per array – may be used for front-end iSCSI network or replication • 4 SFP+ optical or copper • 2 BASE-T |
| Management ports | 2 per array (1Gb BASE-T) |

| Max back-end expansion ports | 4 per array |
| Array configurations | All-flash, hybrid or HDD arrays |
| Storage format | Block (SAN) and/or file (NAS) from same pool** |
| Auto-tiering method | Policy-based migration based on real-time data usage, customizable 512KB-4MB page size |
| Auto-tiering structure | Up to 3 primary (media-based) tiers total, up to 2 SSD tiers (write- and read-intensive SSDs) |
| Tiering customizations | Default and user-defined profiles, option to “pin” volumes to any tier |
| RAID support | RAID 0, 1, 5, 6, RAID 10, and RAID 10 DM (dual mirror); any combination of RAID levels can exist on a single array |
| RAID tiering | Auto-provisions and dynamically restripes multiple RAID levels on the same tier; no need to pre-allocate RAID groups |
| Thin provisioning | Active by default on all volumes, operates at full performance across all features |
| Deduplication and compression | Selectable option per volume on lowest tier (SSD or HDD) Compression-only option also available |
| HDD optimization | FastTrack moves frequently accessed data to outer tracks for quicker response times |
| Replication | Synchronous/Asynchronous via FC or iSCSI Target/source relationships may be one-to-many or many-to-one Supports all SC data services on source and target volumes Change replication types and topologies on demand Supports cross-platform replication with PS Series/EqualLogic arrays (either direction)*** |
| Volume mobility | Live Migrate (included with base product) enables host-transparent data movement between arrays; see also Federation section Maintains snapshots/replication relationships |
| Thin import | Space-efficient, non-disruptive data migration from PS Series (EqualLogic) arrays |
| Thin clones | Clone standalone volumes with zero duplication of data Clones maintain independent snapshots and replication Ideal for VDI, test/dev, other applications that require discrete instances of common data More efficient than dedupe for database copies |
| Business continuity | Live Volume bi-directional auto-failover, auto-repair*** Continuous operations, disaster recovery, disaster avoidance Includes third-site (tertiary) replication options Zero RTO/RPO with customizable site failover SLAs per volume Does not require identical hardware at each site VMware Metro Stretch Cluster support VMware Site Recovery Manager Microsoft Azure Site Recovery support |
| Thin snapshots | Records changes only, snapshots auto-migrate to lower-cost storage |
| Application data protection | Application Protection Manager Suite protects and restores host-side data from array in Oracle, Microsoft or VMware environments |

| Management interface | Dell Storage Manager (DSM), formerly Enterprise Manager Multi-array, multi-site, cross-platform management from single interface |
| Federation | Create large multi-array systems under unified management, with seamless workload migration between arrays via included Live Migrate feature. Add arrays non-disruptively, efficiently utilizing their combined capacity and performance. Volume Advisor monitors federated arrays to suggest optimal data placement and load balancing.
