Lenovo FlashStorage DE4000F 10GbE iSCSI 8/16/32Gb FC* 24x 2,5" SFF 2x Controller shared Storage

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 1/10 Gb iSCSI or 4/8/16 Gb FC, and 12 Gb SAS, 10/25 Gb iSCSI, or 8/16/32 Gb FC at the same time.
For the ThinkSystem DE4000F, customers can change the host port protocol from FC to iSCSI or from iSCSI to FC for the SFP+ host ports built into the controller (base host ports), or the universal SFP+ host ports on the host interface card (HIC ports), or for all SFP+ base and universal HIC ports.

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 cache 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 1/10 Gb iSCSI or 4/8/16 Gb FC, and 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 120 SFF drives with the attachment of up to four 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
