Introduction

Lenovo ThinkSystem DM5000H is a unified, hybrid storage system that is designed to provide performance, simplicity, capacity, security, and high availability for medium enterprises. Powered by the ONTAP software, ThinkSystem DM5000H delivers enterprise-class storage management capabilities with a wide choice of host connectivity options, flexible drive configurations, and enhanced data management features. The ThinkSystem DM5000H is a perfect fit for a wide range of enterprise workloads, including data analytics, artificial intelligence, engineering and design, enterprise applications, and other storage I/O-intensive applications.

ThinkSystem DM5000H models are 2U rack-mount controller enclosures that include two controllers, 64 GB RAM and 8 GB battery-backed NVRAM (32 GB RAM and 4 GB NVRAM per controller), and 24 SFF hot-swap drive bays (2U24 form factor). Controllers provide universal 1/10 GbE NAS/iSCSI or 4/8/16 Gb Fibre Channel (FC) ports, or 1/10 GbE RJ-45 ports for host connectivity.

A single ThinkSystem DM5000H Storage Array scales up to 144 drives with the attachment of Lenovo ThinkSystem DM240S 2U24 SFF, DM120S 2U12, and DM600S 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, 7.2 K rpm NL SAS hard disk drives (HDDs), and SAS solid-state drives (SSDs).


Up to 12 DM5000H Storage Arrays can be combined into a clustered system in a NAS environment, or up to 6 DM5000H Storage Arrays can be combined into a clustered system in a SAN environment.

Did you know?

A single ThinkSystem DM5000H can scale up to 1.24 PB of raw storage capacity. A cluster of the DM5000H storage systems can scale up to 14.9 PB for NAS or up to 7.45 PB for SAN environments.
The ThinkSystem DM5000H offers unified file and block storage connectivity with support for 1 GbE or 10 GbE NAS and iSCSI, and 8 Gb or 16 Gb Fibre Channel protocols at the same time.

• Acceleration of read-centric workloads with the high-speed, low-latency onboard NVMe SSD caching.
• A comprehensive set of advanced storage management features with the ONTAP software, including SSD read cache, hybrid storage pools, snapshots, volume copy, quality of service, thin provisioning, compression, deduplication, encryption, disk-based backup, application- and virtual machine-aware backup, quick data recovery, clustering, synchronous replication, asynchronous replication, and up to 84 drives.
• A core set of storage management features with the ONTAP Fundamentals software, including SSD read cache, hybrid storage pools, snapshots, quality of service, thin provisioning, compression, deduplication, encryption, quick data recovery, and asynchronous replication.
• Optional WORM (write once, read many) (SnapLock) licensed function for the ONTAP software to reinforce permanence and integrity of stored data and to ensure compliance with applicable regulations.
• Scale-out clustering of up to 12 ThinkSystem DM Series storage systems for NAS connectivity or up to 6 DM Series storage systems for SAN connectivity.
• Intuitive, web-based GUI for easy system setup and management.
• Lenovo XClarity support for centralized systems management of Lenovo x86 servers, switches, and storage, which provides automated agent-less discovery, inventory, monitoring, and additional platform-specific functions across multiple systems.
• Designed for high availability with redundant hot-swap components, including controllers and I/O modules, power supplies, and non-disruptive firmware upgrades.
• Certified storage for Oracle VM.

The ThinkSystem DM5000H supports the following drives:

• 2U24 SFF capacity-optimized SSDs: 960 GB, 3.84 TB, 7.68 TB, and 15.36 TB
• 2U24 SFF enterprise SAS HDDs: 900 GB, 1.2 TB, and 1.8 TB 10K rpm
• 2U12 LFF and 4U60 LFF high-capacity nearline HDDs: 4 TB, 8 TB, and 10 TB 7.2K rpm

All drives are dual-port and hot-swappable.
The ThinkSystem DM5000H supports attachment of the following ThinkSystem DM Series expansion enclosures:

• Up to 5 ThinkSystem DM240S 2U24 SFF enclosures.
