Introduction

Lenovo ThinkSystem DE4000H is a scalable, hybrid entry-level storage system that is designed to provide performance, simplicity, capacity, security, and high availability for medium to large businesses. It delivers enterprise-class storage management capabilities with a wide choice of host connectivity options, flexible drive configurations, and enhanced data management features. The ThinkSystem DE4000H is a perfect fit for a wide range of enterprise workloads, including big data and analytics, video surveillance, technical computing, backup and recovery, and other storage I/O-intensive applications.

ThinkSystem DE4000H models are available in a 2U rack form-factor with 24 small form-factor (2.5-inch SFF) drives (2U24 SFF), 12 large form-factor (3.5-inch LFF) drives (2U12 LFF), or a 4U rack form-factor with 60 LFF drives (4U60 LFF) and include two controllers, each with 8 GB or 32 GB cache for a system total of 16 GB or 64 GB. Universal 1/10 Gb iSCSI or 4/8/16 Gb Fibre Channel (FC) ports provide base host connectivity, and the host interface cards provide additional 1/10 Gb iSCSI or 4/8/16 Gb FC, 12 Gb SAS, 10/25 Gb iSCSI, or 8/16/32 Gb FC connections.

The ThinkSystem DE4000H Storage Array scales up to 192 drives with the attachment of Lenovo ThinkSystem DE120S 2U12, DE240S 2U24 SFF, and DE600S 4U60 LFF Expansion Enclosures. It also offers flexible drive configurations with the choice of 2.5-inch (SFF) and 3.5-inch (LFF) form factors, 10 K rpm SAS and 7.2 K rpm NL SAS hard disk drives (HDDs), and SAS solid-state drives (SSDs).

Did you know?

The ThinkSystem DE4000H scales up to 2.3 PB of raw storage capacity, and it 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 DE4000H, 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

• Rich set of standard storage management functions available at no extra cost, including Dynamic Disk Pools, SSD read cache, snapshots, volume copy, thin provisioning, and encryption (requires optional FIPS drives).
• Optional licensed functions, including higher number of snapshots for greater scalability and synchronous or asynchronous mirroring for continuous data availability.
• Intuitive, web-based GUI for easy system setup and management.
• Designed for 99.999% availability with redundant hot-swap components, including controllers and I/O modules, power supplies, cooling modules (4U60 LFF enclosures only), proactive maintenance, and non-disruptive firmware upgrades.

The ThinkSystem DE4000H supports the complete range of data storage requirements, from highly used applications to high-capacity, low usage applications.
The following 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, and 3.2 TB
• High performance self-encrypting FIPS SSDs (3 DWD): 1.6 TB
• Performance-optimized, enterprise class HDDs: 1.2 TB and 1.8 TB 10K rpm
• Performance-optimized, enterprise class self-encrypting FIPS HDDs: 1.8 TB 10K rpm

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 seven ThinkSystem DE240S 2U24 SFF or ThinkSystem DE120S 2U12 LFF, or up to three ThinkSystem DE600S 4U60 LFF, or a combination of the ThinkSystem DE240S, DE120S, and DE600S expansion enclosures for a total of up to 192 drives per system (including controller and expansion enclosures) are supported by a single ThinkSystem DE4000H system.
Customers can intermix 2U24 SFF, 2U12 LFF, and 4U60 LFF expansion enclosures behind a 2U24 SFF, 2U12 LFF, or 4U60 LFF controller enclosure. This configuration delivers the added flexibility to mix 3.5-inch and 2.5-inch drives within a single system (but not within the enclosure).
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.
