Lenovo ThinkSystem DE4000H (64GB Cache) FC Hybrid Flash Array 2U24 SFF – 7Y751003EA
Performance, reliability, and simplicity
Overview
Features
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).
Performance and availability
The ThinkSystem DE Series Hybrid Flash Array with adaptive-caching algorithms was engineered for workloads ranging from high-IOPS or bandwidth-intensive streaming applications to high-performance storage consolidation.
These systems are targeted at backup and recovery, high-performance computing markets, Big Data/analytics, and virtualization, yet they work equally well in general computing environments.
ThinkSystem DE Series is designed to achieve up to 99.9999% availability via fully redundant I/O paths, advanced data protection features, and extensive diagnostic capabilities.
It’s also highly secure, with robust data integrity that protects your critical business data as well as your customers’ sensitive personal information.
Proven simplicity
Scaling is easy, due to the modular design of ThinkSystem DE Series and the simple management tools provided. You can start working with your data in less than 10 minutes.
Extensive configuration flexibility, custom performance tuning, and complete control over data placement enable administrators to maximize performance and ease of use.
Multiple viewpoints provided by graphical performance tools supply the key information about storage I/O that administrators need to further refine performance.
Advanced data protection
With Dynamic Disk Pools (DDP) technology, there are no idle spares to manage, and you don’t need to reconfigure RAID when you expand your system. It distributes data parity information and spare capacity across a pool of drives to simplify the management of traditional RAID groups.
It also enhances data protection by enabling faster rebuilds after a drive failure. DDP dynamic-rebuild technology reduces the likelihood of another failure by using every drive in the pool for faster rebuilds.
The capability to dynamically rebalance data across all drives in the pool when drives are added or removed is one of the key features of DDP technology. A traditional RAID volume group is limited to a fixed number of drives. DDP, on the other hand, lets you add or remove multiple drives in a single operation.
ThinkSystem DE Series offers advanced enterprise-class data protection, both locally and over long distance, including:
- Snapshot / Volume copy
- Asynchronous mirroring
- Synchronous mirroring
