Did you know?

The ThinkSystem DE4000F scales up to 1.84 PB of raw storage capacity.

The ThinkSystem DE4000F offers block storage connectivity with support for 12 Gb SAS, 10/25 Gb iSCSI, or 8/16/32 Gb FC at the same time.

Key features

The ThinkSystem DE4000F offers the following key features and benefits:

  • All-flash array capabilities to meet the demand for higher speed storage and provide higher IOPs and bandwidth with lower power usage and total cost of ownership than hybrid or HDD-based solutions.
  • Scalable entry-level storage with dual active/active controller configurations with 32 GB system memory per controller for high availability and performance.
  • Improved performance and data protection with Dynamic Disk Pools (DDP) technology, as well as support for traditional RAID 0, 1, 3, 5, 6, and 10.
  • Flexible host connectivity to match diverse client needs with support for 12 Gb SAS, 10/25 Gb iSCSI, or 8/16/32 Gb FC connectivity at the same time.
  • 12 Gb SAS drive-side connectivity with support for up to 24x 2.5-inch small form factor (SFF) drives in the 2U24 SFF enclosures.
  • Scalability to up to 96 SFF drives with the attachment of up to 3 ThinkSystem DE240S 2U24 SFF expansion enclosures to satisfy growing needs for storage capacity and performance.
  • Rich set of storage management functions comes with the system, including Dynamic Disk Pools, snapshots, volume copy, thin provisioning, and asynchronous mirroring.
  • Optional synchronous mirroring licensed function for continuous data availability.
  • Intuitive, web-based GUI for easy system setup and management.
  • Designed for 99.9999% availability with redundant hot-swap components, including controllers and I/O modules, power supplies, proactive maintenance, and non-disruptive firmware upgrades.

The following solid-state drives are supported in the 2U24 SFF enclosures:

  • Capacity-optimized SSDs (1 drive write per day [DWD]): 3.84 TB, 7.68 TB, and 15.36 TB
  • High performance SSDs (3 DWD): 800 GB, 1.6 TB
  • High performance self-encrypting FIPS SSDs (3 DWD): 1.6 TB

All drives are dual-port and hot-swappable. Drives of the same form factor can be intermixed within the appropriate enclosure, which provides the flexibility to address performance and capacity needs within a single enclosure.

Up to four ThinkSystem DE240S 2U24 SFF expansion enclosures are supported by a single ThinkSystem DE4000F system. More drives and expansion enclosures are designed to be dynamically added with virtually no downtime, which helps to quickly and seamlessly respond to ever-growing capacity demands.

The ThinkSystem DE4000F offers high levels of system and data availability with the following technologies:

  • Dual-active controller modules with automatic load balancing and failover
  • Mirrored data cache with flash backup (battery-backed destaging to flash)
  • Dual-port SAS SSDs with automatic drive failure detection and rebuild with global hot spares
  • Redundant, hot-swappable and customer replaceable hardware components, including SFP/SFP+ transceivers, controller and I/O modules, power supplies, and drives
  • Automated path failover support for the data path between the host and the drives with multipathing software
  • Non-disruptive controller and drive firmware upgrades
