Introduction

Lenovo ThinkSystem DM7000H is a scalable, unified, hybrid storage system that is designed to provide high performance, simplicity, capacity, security, and high availability for large enterprises. Powered by the ONTAP software, ThinkSystem DM7000H delivers enterprise-class storage management capabilities with a wide choice of host connectivity options, flexible drive configurations, and enhanced data management features. The ThinkSystem DM7000H is a perfect fit for a wide range of enterprise workloads, including big data and analytics, artificial intelligence, engineering and design, hybrid clouds, and other storage I/O-intensive applications.

ThinkSystem DM7000H models are 3U rack-mount controller enclosures that include two controllers, and 256 GB RAM and 16 GB battery-backed NVRAM (128 GB RAM and 8 GB NVRAM per controller). Universal 1/10 GbE NAS/iSCSI or 4/8/16 Gb Fibre Channel (FC) ports and 1/10 GbE RJ-45 ports provide base host connectivity, with an option for additional 1/10 GbE, 25 GbE, or 40 GbE NAS/iSCSI, or 8/16/32 Gb FC connections with the adapter cards.

A single ThinkSystem DM7000H Storage Array scales up to 480 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, 10 K rpm SAS and 7.2 K rpm NL SAS hard disk drives (HDDs), and SAS solid-state drives (SSDs).


Up to 12 DM7000H Storage Arrays can be combined into a clustered system in a NAS environment, or up to 6 DM7000H Storage Arrays can be combined into a clustered system in a SAN environment.

Did you know?

A single ThinkSystem DM7000H scales up to 4.8 PB of raw storage capacity. A cluster of the DM7000H storage systems scales up to 57.6 PB for NAS or up to 28.8 PB for SAN environments.
The ThinkSystem DM7000H offers unified file and block storage connectivity with support for 1 GbE, 10 GbE, 25 GbE, and 40 GbE NAS and iSCSI, and 8 Gb, 16 Gb, and 32 Gb Fibre Channel protocols at the same time.

• Rich set of standard storage management functions available at no extra cost, 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, and asynchronous replication.
• Optional WORM (write once, read many) (SnapLock) and storage virtualization (FlexArray) licensed functions to reinforce permanence and integrity of stored data and to provide additional storage capacity in an ONTAP environment by consolidating storage systems from multiple vendors.
• Scale-out clustering of up to 12 ThinkSystem DM Series storage systems for NAS connectivity or up to six 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 99.9999% availability with redundant hot-swap components, including controllers and I/O modules, power supplies, cooling modules (4U60 LFF enclosures only), and non-disruptive firmware upgrades.
• Certified storage for Oracle VM.
• Certified storage for Citrix XenServer: http://hcl.xenserver.org/storage/910/Lenovo_DM_Series.

The ThinkSystem DM7000H supports the complete range of data storage requirements, from highly used applications to high-capacity, low usage applications. The following drives are supported:

• 2U24 SFF performance-optimized, enterprise class HDDs: 900 GB, 1.2 TB, and 1.8 TB 10K rpm
• 2U24 SFF capacity-optimized SSDs: 960 GB, 3.84 TB, 7.68 TB, and 15.36 TB
• 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 DM7000H supports attachment of the following ThinkSystem DM Series expansion enclosures:

• Up to 20 ThinkSystem DM240S 2U24 SFF enclosures.
